All of these inputs will be 'swallowed' by the private kernel snark.
Note: for a private circuit, we don't need a field for 'custom outputs' from the circuit, since all inputs/output must be known in advance, and so for simplicity can all be considered 'inputs'. | +| `emittedPublicInputs` | Public inputs which will be revealed to the 'public world' (L1 or L2). E.g. allowing certain inputs to be more-easily extracted by the RollupProcessor contract (rather than having to unpack this vast ABI object of inputs, which would cost too much hash-wise). An example of its usefulness is passing a value from L1 to L2 when doing an L1->L2 tx (see 'deposit' example in the other doc). TODO: consider whether this could be a single value, for simplicity. It could be a hash of data if more values need to be exposed. If so, we'll rename to `emittedPublicInputsHash`. | +| `executedCallback: {` | Populated if this circuit is a callback, so that the purported L1 Result to which this circuit is responding can be validated against the l1ResultsTree. | +| `- l1ResultHash`, | If this function is a callback function, following some L1 call, then it needs to expose the `l1ResultHash` to ensure the callback is actually using data emitted by L1. The preimage of the `l1ResultHash` will need to be passed in as private inputs to the circuit. Note: the `l1ResultHash` MUST be computed with a sha256 hash, because that's what the RollupProcessor will have used. This is unfortunate, as it forces apps to adhere to a specific calculation within their circuits. | +| `- l1ResultsTreeLeafIndex`, | Communicates to the rollup provider the correct leaf to prove membership against in the l1ResultsTree. Only if we don't want to hide the callback will the rollup provider perform the membership check (within the Base Rollup Circuit). Otherwise it'll be performed in the Private Kernel Circuit. | +| `}`| +| `outputCommitments` | output notes to be added into the `privateDataTree` (up to 16) | +| `inputNullifiers` | input nullifiers to be added into the `nullifierTree` (up to 16) | +| `privateCallStack` | additional private calls created by this transaction (up to 16) | +| `publicCallStack` | additional public calls created by this transaction (up to 16) | +| `contractDeploymentCallStack` | additional calls which _deploy contracts_, created by this transaction (up to 1?) | +| `partialL1CallStack` | additional calls to L1 created by this transaction (up to 16).

  • `functionSignature` - so that the rollup provider can see how they're to be paid
  • `emittedPublicInputs` - so that the rollup provider can validate the amount they'll be paid (they'll need to be provided with the underlying public inputs separately, to validate the hash).
| +| `bool payFeeFromL1`| Provides a way of paying for private L2 function execution from L1 (the RollupProcessor.sol could provide the interface for ETH or ERC20... but we could generalise this by somehow pointing to a particular 'other' payment L1 contract state?). "Submit on-chain the callHash and state a fee (in L1 currency) for the L2 tx, and then when the L2 tx is executed, the rollup provider may redeem the previously-published fee".

Notifies the kernel circuit that the following public inputs of this private circuit MUST be revealed to the public kernel circuit:
  • `callHash` - no other data is needed (in order to allow the user to keep the function they've actually executed private).
| +| `bool payFeeFromPublicL2`| Provides a way of paying for private L2 function execution from a public L2 circuit. This input being `true` will cause the rollup provider to look for an `isFeePayment` tx in the _public_ callStack. | +| `bool calledFromL1` | If the L1 contract wants to call a specific L2 circuit, then the function signature needs to be revealed on-chain so that it can be checked that the correct, intended function was executed.

Notifies the private kernel circuit that an L1 contract wants to call this specific private L2 circuit, and so the following MUST be revealed to the public kernel circuit:
  • `functionSignature` - needed so the L1 contract can confirm the intended function was executed on L2. Although a callHash contains the functionSignature, the L1 contract wouldn't (cheaply) be able to unpack the callHash. So we expose the function signature as well to keep costs down. Although this leaks the function which was called, there's no way around that; this is an L1 -> L2 call after all.
  • `callHash` - used as a 'lookup' key. The RollupProcessor will store this `callHash`, and await an L2 tx with this `callHash` before triggering a callback to the L1 contract which made this L1 -> L2 call in the first place.
  • `emittedPublicInputs` - needed so that a set of values can be emitted by an L2 function and exposed to L1. It would be too expensive to unpack the callHash and extract all of the custom public inputs of a circuit. This is much cheaper, and is very similar to how the EVM exposes only a few values (via event emissions) to JavaScript (for example).

But that doesn't require explicit public -> private calls. + + +> **Aside:** we don't think we need chained transactions for Aztec 3. Recall: chained transactions give the ability to nullify a newly-created commitment _within_ the same rollup; before it's been added to the dataTree. This isn't needed. For a user to chain state to themselves, they can just create a callstack. The notion of chaining _between_ users is really complicated, and possibly not useful in practice. In particular, chaining doesn't play well with the idea of binary rollup trees, since the number of 'chaining' comparisons would blow up exponentially with the level of the rollup tree (meaning we'd need to build differently-sized rollup circuits per level). Recall: linked transactions give the ability to 'await' the inclusion of 'other' transactions in the rollup, before processing 'this' transaction. Unsure whether that's needed. + + + + + + +## Public Circuit ABI + +The public contract ABI is similar to the private one. + +Whilst the _user_ provides all the values specified by this Public Circuit ABI, it's the _rollup provider_ who actually generates public contract proofs. This is because the rollup provider is the only party with perfect knowledge of the current Merkle roots, meaning only they can access/update the public data tree, as well as know the exact block number etc. + + +| Data Type | Description | +| -------- | -------- | +| `customPublicInputs` | Up to 32 circuit-specific inputs passed into this circuit. All of these inputs will be 'swallowed' by the public kernel circuit. | +| `customOutputs` | Up to 32 variables 'returned' by calling this function. All of these inputs will be 'swallowed' by the public kernel circuit. Note, unlike the private circuit ABI (which doesn't have a `customOutputs` field like this), it's possible for public circuit execution to output values which were derived from the current state of the public data tree - such values cannot have been known by the caller of the function, and hence can truly be considered 'outputs'. Note, since the caller won't necessarily known what these outputs will be when they make the call, this entire `customOutputs` field is omitted from the `callStackItemHash` when the user makes the call. | +| `emittedPublicInputs` | Public inputs which may be revealed to L1. E.g. allowing certain inputs to be more-easily extracted by the RollupProcessor contract (rather than having to unpack this vast ABI object of inputs, which would cost too much hash-wise). An example of its usefulness is passing a value from L1 to L2 when doing an L1->L2 tx (see 'deposit' example in the other doc). | +| `emittedOutputs` | As above, except these values won't necessarily be known when the call is made; only when the rollup provider is generating the witness for this function's execution. Note, since the caller won't necessarily known what these outputs will be when they make the call, this entire `customOutputs` field is omitted from the `callStackItemHash` when the user makes the call. | +| `executedCallback: {` | Populated if this circuit is a callback, so that the purported L1 Result to which this circuit is responding can be validated against the l1ResultsTree. | +| `- l1ResultHash`, | If this function is a callback function, following some L1 call, then it needs to expose the `l1ResultHash` to ensure the callback is actually using data emitted by L1. The preimage of the `l1ResultHash` will need to be passed in as private inputs to the circuit. Note: the `l1ResultHash` MUST be computed with a sha256 hash, because that's what the RollupProcessor will have used. This is unfortunate, as it forces apps to adhere to a specific calculation within their circuits. | +| `- l1ResultsTreeLeafIndex`, | Communicates to the rollup provider the correct leaf to prove membership against in the l1ResultsTree. Only if we don't want to hide the callback will the rollup provider perform the membership check (within the Base Rollup Circuit). Otherwise it'll be performed in the Private Kernel Circuit. | +| `}`| +| 256 `stateTransitions` | Describes up to 256 `publicDataTree` read+write operations.
A 'state transition' is expressed as:
`[storageSlot, old_value, new_value]`.
:heavy_exclamation_mark: For state transitions, the caller might not know the `old_value` nor the `new_value` when they make the call (i.e. when they add the call to their callStack), since the value will depend on the current state of the publicDataTree. (Imagine if the storage slot represented total liquidity in some pool which changes frequently. Then the old and new values are only known at the time the rollup processor actually organises the ordering of txs in their block). Conclusion: the `publicInputsHash` which is included in a public call's `callStackItemHash` cannot include the `old_value` nor `new_value` inputs.

Therefore, the `stateTransitions` that are populated by a user and hashed when generating the `callStackItemHash` will have `0`-valued placeholders for `old_value` and `new_value`.

Pure reads can be emulated by setting a new write value to equal the read value. However, for this tree, we could halve the amount of hashing for pure reads by having a separate `reads` set of inputs. A read can be done without a write for this tree (see next field). | +| `stateReads` | Pure reads. Each 'read' request is simply the `[storageSlot, current_value]`. As explained above, the `current_value` won't necessarily be known by the user when they generate the call, so `current_value` is replaced with `0` when the `callStackItemHash` is generated for calls to a public function. | +| `publicCallStack` | additional public calls to be made by this transaction (up to 16) | +| `contractDeploymentCallStack` | additional calls which _deploy contracts_, created by this transaction (up to 1?) | +| `partialL1CallStack` | Additional L1 calls to be made by this transaction (up to 16). "Partial" because the kernel circuit will add the correct portal contract address to 'complete' the call into a proper L1 CallStack Item. See [here](../contracts/l1-calls.md). | +| 
callbackStack = [{
  callbackPublicKey, 
  successCallbackCallHash, 
  failureCallbackCallHash, 
  successResultArgMapAcc,

| An element in the array for each new L1 call on the `partialL1CallStack`. See [more](../contracts/l1-calls.md). We need to expose all of this data so that the kernel snark ensures the callback is a function of the same contract which made the call. | +| `oldPrivateDataTreeRoot` | used to query the `privateDataTree` | +| `proverAddress` | Who is going to be generating the proof for this circuit (any value can be injected here by the prover). :question: IS THIS ALLOWED HERE? It can be allowed here as long as Noir abstracts its existence away from the circuit developer. | +| Booleans: | | +| `bool isFeePayment` | Notifies the rollup provider that this function pays them their fee. The rollup provider will need a way to interpret the many ways it can be paid. :question: Perhaps a fee payment ABI is required for the structure of the `emittedPublicInputs`, for example? | +| `bool payFeeFromL1`| Provides a way of paying for L2 function execution from L1 (the RollupProcessor.sol could provide the interface for ETH or ERC20... but we could generalise this by somehow pointing to a particular 'other' payment L1 contract state?). "Submit on-chain the callHash and state a fee (in L1 currency) for the L2 tx, and then when the L2 tx is executed, the rollup provider may redeem the previously-published fee".

Notifies the kernel circuit that the following public inputs of this public circuit MUST also be revealed by the public kernel circuit:
  • `callHash`
| +| `bool calledFromL1` | If the L1 contract wants to call a specific L2 circuit, then the function signature needs to be revealed on-chain so that it can be checked that the correct, intended function was executed.

Notifies the public kernel circuit that an L1 contract wants to call this specific public L2 circuit, and so the following MUST be revealed by the public kernel circuit:
  • `functionSignature`
  • `callHash`
  • `emittedPublicInputs` (possibly)


We need this convoluted process, because the RollupProcessor has to be _sure_ an L1 fee has been set-aside for them, before they add any corresponding L2 states. | +| Global vars: | | +| `block.timestamp` | aztec block timestamp | +| `block.number` | aztec block number | +| `prevBlock.ethTimestamp` | Ethereum timestamp of block that contained previous Aztec 3 block | +| `prevBlock.ethNumber` | block number of Ethereum block that contained previous Aztec 3 block | + +### publicInputsHash + +As explained briefly in the table above, for calls to a public circuit, certain inputs are _not_ known when the user makes the call (since their values might depend on the state of the public data tree at the time of proof generation (rather than at the time of making the call)). Therefore, the `publicInputsHash` for public calls is defined as the hash of the above ABI data, _except_ for the following modifications to the preimage: +- `customOutputs` fields are completely omitted from the preimage. +- `emittedOutputs` fields are completely omitted from the preimage. +- Each state transition is truncated to be `storageSlot` (instead of `[storageSlot, old_value, new_value]`). +- Each state read is truncated to be `storageSlot` (instead of `[storageSlot, current_value]`). + + + + + + + + + +## Contract Deployment ABI + +Recall: + +Contracts can be deployed to Aztec's Layer 2.

These public inputs will then be hashed into a `publicInputsHash` which will form part of the [`callStackItemHash`](../contracts/transactions.md#callstackitemhash) which will get added to the `contractDeploymentCallStack`. + +**Important note**: Unlike for the above Public Input ABIs for private circuits and public circuits, we don't actually have a 'contract deployment' _circuit_. These public inputs are simply defined so that a callStackItem can be created. These public inputs (and others) are then fed directly into a [Contract Deployment _Kernel_ Circuit](../kernel-circuits/contract-deployment-kernel.md). + + +TODO: we might be able to remove some of these public inputs and provide them privately instead; but such optimisations can happen _much_ later in this project. + +| Data Type | Description | +| -------- | -------- | +| `privateConstructorPublicInputsHash` | So that vested parties (with access to the underlying public inputs) can confirm the constructor was executed with the correct params. Note: a user (or contract) cannot provide a conventional callStackItem to make a call to a private constructor, because the constructor's function signature isn't known until the contract address is known, but the contract address needs to contain the constructor arguments (i.e. the privateConstructorPublicInputsHash), so we'd get a cyclic dependency. | +| `publicConstructorPublicInputsHash` | As above, but public. | +| `privateConstructorVKHash` | The hash of the vk that was used to verify the private constructor, so that vested parties can confirm the correct function was run as a constructor (the vk itself may OPTIONALLY be submitted on-chain as calldata (for data availability), but some users might want to keep that private).
(Note, we can't use function signatures here, because the contract hasn't yet been deployed, so no contract address exists!) | +| `publicConstructorVKHash` | As above, but public. | +| `contractAddress` | The proposed contract address that this new contract will be deployed to. | +| `salt` | The salt used in the preimage of the contractAddress derivation - to have some control over the contract address | +| `vkRoot` | The root of the mini merkle tree of VKs. Note: the underlying data (the circuit's compressed ACIR representation) can optionally be submitted on-chain as calldata (for data availability), but some users might want to keep that info private, or might not want to pay for that. | +| `circuitDataKeccakHash` | For example, a hash of the circuit's compressed ACIR representation. This value will be read on-chain by the RollupProcessor.sol. If it's `0`, it's assumed the user didn't want data to be submitted (to keep their contract logic private). If it's nonzero, the rollup provider MUST submit the hash's preimage as calldata. To ensure the rollup provider does actually submit, the RollupProcessor.sol will try to reconcile the hash, and reject if it doesn't reconcile. Note, there's no explicit checks that can be done (within a snark or on-chain, due to expense) to ensure this `circuitDataKeccakHash` actually corresponds to the `vkRoot`. Clients (off-chain) must decompress the submitted circuit data, recreate the verification keys, then recreate the `vkRoot`, to be convinced the deployed contract actually represents the logic they expect. If circuit data isn't submitted here (to keep the logic of the contract private), then the developer must find another way (off-chain) to circulate the ACIR representations of the circuits to their users. | +| `portalContractAddress` | Gets calculated within the circuit and stored in the `contractTree` (within the same leaf as the contract's vkTree). We expose it here, because the RollupProcessor will need redo this calculation to ensure it's been done correctly. | + + + + + + + ## Custom inputs ABI + +Circuits have up to 32 custom 'inputs' (and 'outputs' for public circuits). Each Noir data type that is set to be a public input is represented by a single field element (we don't need to do this for private inputs). If the data type is >1 field element, the data is Pedersen hashed. We apply this heuristic recursively for structs and nested data. e.g. for + +``` +struct foo { + field a; + bytes b[256]; +}; +``` + +`b = pedersen(b.values), foo = pedersen(b, a)` + +:question: Can we instead go for `foo = pedersen(a, b)`? Hmmm, actually, maybe it is easier to mirror the Solidity ABI, to avoid mistakes? + +The full, uncompressed values will be attached to the transaction as 'auxiliary data', used by the proof creator to unpack the hashed values. This data will be swallowed before the transaction gets mined into a block.

Indeed, conventional programs execute in the order dictated by their code: if a line makes a call to another function, the program will 'jump into' that function and start executing its code, and so-on in a big nesting of calls, until eventually the inner-most call completes and returns some variables. Then program starts unwinding back up the nesting to the originally-called function. That's perhaps not the best mental model for Aztec programs ('transactions')... + +As you might have guessed, 'functions' in Aztec's L2 will actually be circuits. Execution of a function will be performed by generating a zk-snark to prove its correct execution with a particular set of inputs. If a function makes a call to another function, a proof of each function's execution must be made _separately_. We need to then 'connect' those two proofs in a way which says "this function made a call to this other function, it passed-in these arguments and received these values in return". To do this, we make use of zk-snark recursion and a special 'callstack'. Notice that if each function must be executed as a standalone lego brick (a proof), then all input arguments and return values of every function call in a transaction must be known ahead of time, so that each proof can be generated separately. That'll be a fun engineering challenge! + +This is all expanded-on later in this book. When a function calls another function, we'll add details of the function _being called_ to a callstack[^1]: the contract address, the function signature, arguments, return values and a call context. We describe a 'Kernel Snark' which: pops the first proof off the callstack, verifies it, then adds new callstack items for any functions which the first function called. Kernel Snark execution proceeds recursively: the next Kernel Snark will verify the previous Kernel Snark's correctness, then will pop the next proof off the callstack, and add even more callstack items for any functions which this latest function has called. The 'stitching together' of arguments passed to functions and values returned from functions is implicit in this process, since each callstack item contains this information. + +This protocol describes 'private states' (a state whose value is known by a single user) and 'public states' (states whose values are visible to everyone).

Private circuit proofs are generated by msg.sender's client, and are hidden by the client by verifying the proof inside a private kernel circuit (thereby hiding which verification key in the contractTree has been used). + +_Note_: input and output values will also be hidden, unless calling a public or L1 function, in which case any arguments passed to the public or L1 function will need to be public. The number of such arguments and the values of such arguments might leak information about the nature of the private function being executed. This must be clear to developers who write private functions. +_Note_: The function and contract address are hidden _up-to_ the number of commitments and nullifiers (so observers might be able to 'guess' the function being called from this info). This can be mitigated by adding an extra call at the end of the private callstack (see later) which calls a special 'padding' function which adds extra commitments/nullifiers to the kernel snark's `end` arrays. + +## Public Function + +As mentioned, in addition to private transactions and calls to L1 contracts, it will be valuable to add support for general-purpose 'public' functions, that are not privacy preserving.

Aztec Connect did a lot of the thinking, and here we're just trying to generalise those ideas beyond the single 'defi interaction' interface. + +Firstly, in order for a contract (or user) to make a call to an L1 function, they need an L1 address. That's one of the main purposes of the Portal Contract; to provide an Aztec L2 contract with an L1 contract address through which it can make calls to other L1 functions. So an L2 contract MUST make L1 calls _through_ its Portal Contract. I.e. _all_ calls from an L2 contract will be _to_ that contract's Portal Contract. It's then up to the logic of the Portal Contract to forward calls to other L1 contracts' functions. + +Now, an L2 circuit might both make state changes _and_ make calls to L1. The L2 circuit's execution MUST NOT be considered 'final', until the L1 calls have been mined, as only then can we know if the L1 calls were successful/unsuccessful. That means any state changes which the L2 circuit is proposing to make (to either the `privateDataTree` or the `publicDataTree`) MUST NOT be included (as final states) in the trees until the L1 execution completes. Furthermore, the L2 circuit might also be 'awaiting' some values or on-chain state updates from the L1 call(s) before being able to insert new L2 states into the trees. + +> An example is Aztec Connect's defi interactions. You can think of the 'defi deposit' circuit as calling a bridge on L1. We _want_ to create states containing the user's share of funds _returned_ by the L1 bridge. But the defi deposit circuit cannot make such state updates. So it instead creates a partial commitment (which in Aztec 3 we can add to a state variable in the public data tree). It's only after the L1 tx is completed that we know the value to inject into that partial (or 'pending') state. The claim circuit then injects the value and adds the _finalised_ state to the privateDataTree. See more on this example [here](./function-types.md#examples). + +As a generalisation for Aztec 3, we we can think of the claim circuit as a 'callback function', which is executed after the result of the L1 tx is known. + +We outline a general protocol below. Here are the main differences from Aztec Connect: +- For each L1 call, two 'callback functions' are submitted; one to be executed upon success, and one upon failure of the L1 tx. +- Whereas 'defi deposits' are summed in the rollup circuit in Aztec Connect, that cannot happen in Aztec 3, because app specific logic must not live in a rollup circuit. Instead, such app-specific logic would need to be in a public circuit. See the dedicated example [TODO: EXAMPLE] for more details. +- In Aztec Connect, the rollup circuit expects a defi interaction note to have a specific format (that of a defi interaction). In Aztec 3, the rollup circuit has no knowledge of the number of values contained in an L1 result; it deals with already-compressed (hashed) leaves which contain callback and result data. +- In Aztec Connect, there's no callback in case a withdrawal's L1 call fails. If it fails, a user has spent money on L2, but hasn't received money on L1 (they've lost money effectively). In Aztec 3, we could specify a failure callback which could reinstate the user's L2 balance (for example). + + + +### Protocol for L2 --> L1 calls. + + +#### Overview + +- L2 function makes call to L1 +- Two callback hashes (see below) get encoded into a single leaf of the `l1ResultsTree` - one for success and one for failure. + - A callback hash contains a: + - function selector + - a set of `emittedPublicInputs` that must be emitted by the callback. + - Leaves without data relating to the success/failure of the L1 call are considered "pending". +- The RollupProcessor.sol makes an L1 call for every callstack item on the `l1Callstack`. +- The return data of each L1 call is sha256-hashed into an `l1ResultHash` (singular). + - If the L1 call failed, this is also encoded in the `l1ResultHash`. +- Those hashes are all sha256-hashed together into a single `l1ResultsHash` (plural), to save on storage costs. The RollupProcessor.sol stores this for reference, so it may do a comparison against the next rollup. +- In the very next rollup, the rollup provider is _forced_ to execute an "L1 Results Copier Circuit" which copies all L1 results of the previous rollup over to L2, so that L2 circuits may access the results more easily. + - The circuit "finalises" each "pending" leaf of the `l1ResultsTree` by adding the `l1ResultHash` to the leaf. The leaf will be structured in such a way that a success result will be stored against the success callback. + - The RollupProcessor.sol will check the "L1 Results Copier Circuit" was executed correctly, by checking: + - The `l1ResultsHash` matches that which was stored. + - The leaf indices of the `l1ResultsTree` which were updated, were the correct leaves to update. +- A user can then call the relevant L2 callback function of a particular 'completed' L1 call. + - Public/Private circuit ABIs contain an `isCallback` indicator, to enable the kernel/rollup circuits to perform extra checks on the validity of this callback, relative to the data in the `l1ResultsTree`. + - The callback circuit will expose: + - its `emittedPublicInputs` + - The `l1ResultHash` of the L1 call to which this callback is responding.

The syntax might look something like the below, where we intentially use the result in a tricky way: + +```js +uint x; + +L1Promise promise = await L1_Portal_Contract.my_l1_function(amount_a); + +promise.then( + result => fn1(result[1], x, result[0], result[2]), // on success, the result will + // effectively be an array of + // values. + fn2(x), // results cannot be passed to the failure + // callback. +); + +function fn1(uint a, uint b, uint c, uint d) { + // do stuff +} + +function fn2(uint a) { + // do stuff +} +``` + +Notice how, upon success of the `promise`, the `result` array (in this example) is passed to `fn1` in a funny order. This is what the `successResultArgMapAcc` is for (until we find a better method). For now, we can create a simple 'accumulator' (although it's not a one-way function) using prime numbers. Later, we can do something cleverer (although anything more than 10 L1 Results and plookup might not be an option, since 11! = 40 million mapping combos). With this 'simple' approach, we can allow up to 10 result values to be returned (since `max := 29^10 * 23^9 * 19^8 * 17^7 * 13^6 * 11^5 * 7^4 * 5^3 * 3^2 * 2^1` doesn't overflow (it's 214-bits), but `31^11 * max` is 269-bits. Actually, initially let's allow 8 L1 Results + +``` +result index: 0, 1, 2, 3, 4, 5, 6, 7, +... maps to arg position: 3, 1, 4, -, -, -, -, -, (indexed from 1) +prime for this arg position: 2, 3, 5, 7, 11, 13, 17, 19, + + +successResultArgMapAcc = 2^3 * 3^1 * 5^4 = 15000 // we can do powers, since the power is + // always bounded by 8. It's messy + // though. +``` + +When the callback is eventually executed, it'll expose its `customPublicInputs`, the `successResultArgMapAcc`, and the `l1ResultHash` to the kernel circuit. In this 'simple' solution, we can also pass binary decompositions of the arg positions (`l1SuccessResultArgPositions`) and the underlying values of the `l1ResultHash` (`l1ResultValues`) as private inputs to the kernel circuit. Using these, we can ensure the results were mapped to the correct argument positions of the callback circuit. + +## Alternative approach to callbacks + +The approach to callbacks described in this book (at the moment) is that a callback can only be executed once, and then it's 'nullified' from the L1 Results Tree by the kernel circuit (or rollup circuit). That means an L1 result can only be 'referred-to' once, by a single callback. This differs from Aztec Connect's claim circuit functionality, where the L1 Result (the defi interaction note) can be referred-to many times by the claim circuit; it's up to the claim circuit to ensure it has logic to allow multiple 'nullifications' of the L1 result. We _could_ adopt a similar approach; leaving handling of nullification of an L1 Result to the callback circuit (rather than nullifying in the kernel), but that would require much more care from users to ensure the nullifier is well defined. + +**Pros** (of the approach currently described in this book): +- The kernel snarks handle all callback handling logic and L1 Result nullification logic, so it's simpler for users (devs). + - A 'nullifier' of an L1 Result can always be understood to be a 'one time use' thing. + - In the 'alternative approach', 'nullification' logic (of L1 Results) is up to the developer. +- The L1 Result callbacks are structured similarly to other languages, e.g. in Rust, a Result has an 'OK' and an 'Err' callback, and the callback can only be called once. + +**Cons** +- To achieve defi-bridge logic with this book's approach, there needs to be an extra step: + - The L1 Result callback would need to copy the L1 Result (the 'total amounts' from the defi interaction) into the public data tree. + - Then individual 'claim circuits' could be executed - they'd lookup the 'total amounts' from the public data tree (not from the L1 Result tree, since an L1 result can only be referred-to once, before it gets nullified). +- The 'alternative approach' is perhaps more flexible if a dev knows what they're doing. +- The 'alternative approach' might make kernel and rollup snarks slightly cleaner. \ No newline at end of file diff --git a/circuits/specs/src/architecture/contracts/states-and-storage.md b/circuits/specs/src/architecture/contracts/states-and-storage.md new file mode 100644 index 00000000000..2c7e4126d25 --- /dev/null +++ b/circuits/specs/src/architecture/contracts/states-and-storage.md @@ -0,0 +1,114 @@ +# States & Storage + +# States + +There are 3 kinds of state to be aware of in Aztec 3, and these reflect the [function types](./function-types.md) of Aztec 3: + +- Private States (L2) +- Public States (L2) +- L1 states (public by definition) + + +## Private States + +Private states are state variables which are private to a single user (or a group of users if we do multisig stuff).

:question: Is this needed? Perhaps the differences in private/public ABIs is sufficient to cause a circuit to fail if passed the wrong proof type? Or, maybe the vk tree could be arranged in a way which clearly separates public/private vks. | +| 62 (1-bit) | `isConstructor` - If a function is a constructor, it's going to be called by the Contract Deployment Kernel circuit. This flag notifies the kernel circuit that this private circuit is being executed as a constructor for the deployment of a new contract, and so the following public inputs of this private circuit MUST be revealed to the public kernel circuit (so that the Contract Deployment kernel circuit may validate them):
  • `callStackItemHash` - so that the Contract Deployment kernel circuit (and interested parties) can be convinced that the constructor was run with the correct set of inputs (this might need to exposed all the way to L1)
  • `vkHash` - so that the Contract Deplyment constructor can validate that the correct function was executed. (Notice, we don't use a conventional `functionSignature` because we won't be adding constructor vkHashes to the vkTree). Notice, by design, this doesn't reveal any details to observers about the nature of the executed function. We might want to optionally allow the underlying vk to be broadcast (and hence we might need to expose this vkHash all the way to L1).
  • `emittedPublicInputs` - to pass particular inputs to L1.

Special note: this `isConstructor` flag is not part of the private circuit's ABI (as it potentially could have been), because the checks in the contract deployment kernel circuit are much cheaper if it's accessible here. | +| 63 (1-bit) | `isCallback` - Tells the kernel circuit that this function is being executed as a callback from an earlier L2 --> L1 call. | + + +_Note_: the `contractTree` is append-only, so individual verification keys can't be 'replaced' for bug-fixes etc.; the entire contract (a `vkTree`) would need to be re-deployed to the next available slot in the `contractTree`. Such re-deployments, of course, would change the contract address. + +--- + +## Call Stacks + +To fully define how Aztec 3 implements call semantics, we start by defining 4 call stack data structures. + +A call stack is a vector where each entry describes a transaction that is yet to be processed. + +There are 4 call stack types in the Aztec 3 architecture: public calls, private calls, L1 calls (see [earlier](./function-types.md) for details of those 3), and [contract deployment](./deployment.md) calls. + + +### Structure of a call stack item + +A call stack item contains the following witnesses: + +| Data | Description | +| -------- | -------- | +| `functionSignature` | The 'function signature' of the circuit being called. I.e. `concat(contractAddress, vkIndex, isPrivate)` (see earlier) | +| `publicInputsHash` | The public inputs of the call (represented as a pedersen hash. Preimage provided as auxiliary data. When a call stack item is processed, the preimage is unpacked).

Note: for the public circuit ABI, _not all_ public inputs are hashed to form this `publicInputsHash`, since variables read/written from/to the publicDataTree are not known at the time the call is made by the user (or by another circuit). See the Public Circuit ABI section. | +| `callContext: {` | 'Object' for distinguishing between `call` and `delegateCall` | +| ` - msgSender,` | - If doing a `call` or `staticCall`: Either the user address or the address of the contract that created the call. (Can be set to `0` for private -> public calls)
- If doing a `delegateCall`: the address of the calling contract's own `callContext.msgSender` (since delegate calls can be chained). | +| ` - storageContractAddress,` | - If doing a `call` or `staticCall`: the address of the contract being called.
- If doing a `delegateCall`: the address of the calling contract's own `callContext.storageContractAddress` (since delegate calls can be chained). | +| `}` | | +| `bool isDelegateCall` | Used by the kernel snark to validate that the `callContext` of newly-pushed `callStackItems` is consistent with the contract making the call. | +| `bool isStaticCall` | Informs the kernel snark that it MUST fail if the function being called modifies state.

A state modification includes: creating a new contract; emitting events; writing to trees; making a 'call' to another contract. :question: Not sure why 'delegatecall' is not included as a potentially state-modifying tx in ethereum specs?

Note: static calls to private circuits might not make sense. 'Reads' from the privateDataTree require a write of equal value, but the kernel snark cannot 'see' what has been written (it's a private tx), and so cannot validate that a state change didn't take place. So there would be no output commitments or nullifiers for a private static call. But a private call's only use is (I think :question:) to read/modify private state. So I'm thinking a staticCall to a private circuit doesn't make sense. | + +> Note: A `proof` is not included in the call stack item. For public calls, the proof is not known at the time the call is made, because public proofs are generated by the rollup provider. For private calls, the proof isn't needed for a call stack item to be unique; the input nullifiers and output commitments ensure uniqueness of calls. :question: Q: is a private call which doesn't read/modify state nonsensical (if so, that's good - we can reject such calls (they won't have any nullifiers or commitments), thereby ensuring uniqueness of private callStack items)? + +> Note: Certain public inputs are omitted when calculating the publicInputsHash for a public call stack item, because such inputs will depend on the 'current' state of trees, which won't be known by the caller; only by the party executing the call. + +> Note: Certain public inputs are omitted when calculating the publicInputsHash for a callback's call stack item, because such inputs will depend on the L1 Result. + +> Note: The `contractAddress` is sometimes set to `0` in the `functionSignature` if a function is calling another function of the same contract. (Functions cannot know their own contract address, since it is set after the function's circuit has been compiled). The kernel circuits are capable of interpreting this. Examples of a function calling another function of the same contract are: a private-to-public call; and a call to a callback function. + + +#### `callStackItemHash` +`callStackItemHash := hash(functionSignature, publicInputsHash, callContext, etc.)` +a.k.a. `callHash` - similar to Ethereum's notion of a txHash. + +We also use the term `callbackCallHash` to refer to the `callHash` of a callback function (which has certain public inputs omitted when calculating the call stack item). + +Having a single value for each item on the stack (a hash) makes thinking about the callstack easier. + +#### Contract Deployment call stack item + +An instruction to deploy a contract is also expressed through a call, but the call stack item's data is slightly abbreviated (no function signature): + +| Data | Description | +| -------- | -------- | +| `publicInputsHash` | The public inputs of the call (represented as a pedersen hash. Preimage provided as auxiliary data. When a call stack item is processed, the preimage is unpacked). | +| `callContext: {` | 'Object' for distinguishing between `call` and `delegateCall`. :question: Not sure if we need this for a contract deployment? | +| ` - msgSender,` | | +| ` - storageContractAddress,` | | +| `}` | | +| `bool isDelegateCall` | | +| `bool isStaticCall` | | + +### L1 callstack items + +An L1 callstack item is a call to L1. So it's the Ethereum-defined tuple (functionSelector, argument encoding). See [here](https://docs.soliditylang.org/en/v0.8.11/abi-spec.html#function-selector-and-argument-encoding). + +Given that the argument encoding is of a variable size, we can't handle such a thing in our kernel snarks. The easiest thing to do is probably to hash the L1 call's `functionSelector, argumentEncoding` into a single value, and then unpack that value when we come to use it on-chain in the RollupProcessor.sol contract. We should probably use a **keccak256** hash for this, which is cheap on-chain (but unfortunately expensive within a snark). + +To ensure the `l1CallStackItem` is a call to the correct portal contract (that is associated with the contract making the call), the kernel circuit adds the `portalContractAddress` to the preimage of an `l1CallStackItem`. + +We disambiguate the two calls (with and without a portal contract address) with their name. + +So: +- In an app-specific circuit: + - `partialL1CallStackItem = keccak(functionSelector, argumentEncoding)` +- In the kernel circuit, it gets modified to include the portal contract address of the calling contract: + - `l1CallStackItem = keccak(portalContractAddress,l1FunctionCall)` + - We don't do this within the app-specific circuit to save on expensive keccak hashing (since the kernel has to do a portal contract address check, so needs to do this hashing already). + + +### Passing inputs between functions + +Brief explanation of passing inputs between functions: + +Suppose function F0 calls F1 and F2, passing parameter set P1 to F1 receiving response R1 (similar for F2). + +Firstly, note that R1 & R2 don't really exist (for private circuits, at least) - there's no return data, it's all input params P1 & P2, because it's a circuit. + +So to call F1, F0 adds a callstack item to its public inputs representing a call to F1: + +``` +callStackItem = { + functionSignature, + publicInputsHash, + callContext, + etc. +} +``` + +Notice the parameters P1 are squished into the `publicInputsHash`. It's up to the logic of function F0 to interpret the underlying public inputs of this callstack item as input params or return params of F1. + +Similarly, it's up to the logic of function F0 to interpret the underlying public inputs of the F2 callstack item as input params or return params of F2. + + + +## Function visibility + +TODO: maybe move this section? + +Aztec contracts will support `internal`, `public` and maybe also `external` function visibility. But this logic will happen at the Noir level. We don't need the core architecture (i.e. the kernel circuits) to perform checks on the visibility of functions, as explained below: + +Suppose a contract `A` is calling a contract `B`: + +- If `B` is `internal` it won’t exist as a distinct verification key (it'll just be part of A's circuit). +- If `B` is `public` it will exist as a distinct verification key but there is nothing stopping a compiler from rolling an implementation of `B` into other functions in the same contract that call `B` (in fact this is probably exactly what will happen). +- If `B` is `external` there is nothing the kernel snark can do to validate the compiler has chosen or not chosen to roll an implementation of an external function into a different function in the same contract. + +It's just language semantics.

+
+- `require(previousKernel.publicInputs.isPublic == false && previousKernel.publicInputs.isContractDeployment == false)`
+
+
+TODO: less nesting! (Or, in practice, we'll modularise this all into neat functions).
+
+Base case:
+* if `start.privateCallCount == 0`:
+    * Require previous kernel data to be empty.
+    * Validate that `start.privateCallStack.length == 1 && start.publicCallStack.length == 0 && start.contractDeploymentCallStack.length == 0 && start.l1CallStack.length == 0`
+        - TBD: to allow the option of a fee payment, we might require `start.privateCallStack.length` to be "1" or "2, where one tx has an `isFeePayment` indicator". We could even allow any number of initial private calls on the stack, but that's a pretty big deviation from the ethereum tx model.
+    * Pop the only (TBD) `privateCallStackItemHash` off the `start.privateCallStack`.
+        - If `privateCall.functionSignature.isConstructor == true`:
+            - then we don't need a signature from the user, since this entire 'callstack' has been instantiated by a Contract Deployment kernel snark (which itself will have been signed by the user).
+            - Set `constants.isConstructorRecursion := true` - This public input will percolate to, and be checked by. the Contract Deployment Kernel Circuit which calls this constructor. This check is required to prevent a person from circumventing the ECDSA signature check by simply setting `isConstructor = true` when making a private call. If this aggregated kernel snark reaches the rollup circuit without this flag being reset to `false` by the Contract Deployment Kernel Circuit (to say "yes, this kernel was indeed a constructor for a Contract Deployment Kernel Circuit"), then the entire tx will be rejected by the rollup circuit.
+        - Else:
+            - Set `constants.isConstructorRecursion := false`
+            - Verify the ECDSA `signature`, with `message := privateCallStackItemHash` and `signer := privateCall.callContext.msgSender`.
+            - Validate the `callContext`. Usually the correctness of a callContext is checked between the `privateCall` and all the new calls it makes (see later in this logic). That means for this 'Base case', those checks haven't been done for this `privateCall` (since there was no prior iteration of this kernel circuit to make those checks).
+                - If `privateCall.isDelegateCall == true || privateCall.isStaticCall == true`:
+                    - Revert - a user cannot make a delegateCall or staticCall.
+                - Else:
+                    - Assert `privateCall.callContext.storageContractAddress == privateCall.functionSignature.contractAddress`
+        - If `privateCall.functionSignature.isCallback == true`:
+            - Set `constants.isCallbackRecursion = true;` - this can only be set in the _first_ call of a recursion.
+            - We can infer whether the user wants to keep this callback's execution private, or if they want to expose it, from the `privatelyExecutedCallback` private inputs:
+            - If `privatelyExecutedCallback` is zeroes, then the user doesn't want to execute this callback privately (maybe it interacts with some public state tree data).
+                - Let `exposeCallback := true;`
+                - Copy over the `privateCall.publicInputs.executedCallback` data to this snark's output: `constants.executedCallback`.

+                - Extract `{ l1ResultHash, l1ResultsTreeLeafIndex } = privateCall.publicInputs.executedCallback;`
+                - If `l1ResultHash != 0` (success):
+                    - Check the successCallback's `functionSignature` matches the `privateCall`'s:
+                    - `require(successCallback.functionSignature == privateCall.functionSignature)`
+                    - In fact, check the entire callbackCallHash reconciles.
+                    - Also check the `successResultArgMapAcc` reconciles.
+                      - Extract array `positionData = privateCall.privatelyExecutedCallback.l1SuccessResultArgPositions;`
+                      - Extract the underlying results `l1SuccessResultValues = privateCall.privatelyExecutedCallback.l1SuccessResultValues;`
+                      - Reconcile the `privateCall.privatelyExecutedCallback.callbackStackItem.successResultArgMapAcc` against `positionData` (messy computation if using turboplonk).
+                        - `positionData` is probably binary decompositions, so range checks aren't needed. Multiply all the stuff together with the primes (details omitted, since this solution is a stop-gap). No need to prevent duplicate positions here: the app circuit must do that when it makes the initial call.
+                        - Compare the resulting value against `successResultArgMapAcc`.
+                        - Then, for turbo: sum each of the `positionData` 'columns' to get the `position` as a value. For each `position` loop through the `privateCall.publicInputs.customPublicInputs` until reaching the index `i` of the `position`, and then `require(customPublicInputs[i] == l1SuccessResultValue[i]`. What a pain - Bring on ultraplonk!
+                - Else:

+                    - `l1ResultsTreeLeafIndex`
+                    - `l1ResultsTreeSiblingPath`
+                    - `constants.oldTreeRoots.l1ResultsTree`
+                - Validate the `callbackPrivateKey`:
+                    - `require(callbackPrivateKey * G = callbackPublicKey)` (for some fixed point `G`).
+                - Set `callbackNullifier := hash(callbackDatumHash, callbackPrivateKey)` to prevent this callback from being executed again.
+                - Set `isCallbackRecursion = false;` to hide that this is a callback, and to prevent callback logic being triggered later in the Base Rollup circuit.
+                - Ensure `constants.executedCallback` is zeroes.
+                - We don't include the whole `leafValue` in the preimage of the nullifier, to prevent a user maliciously calling the callback twice: once for 'success' and once for 'fail' (although that shouldn't be possible if the 'L1 results copier' circuit works correctly).
+        - Else:
+            - Set `isCallbackRecursion = false;`
+            - Assert `l1ResultHash == 0`

+Recursion:
+* If `previousKernel.publicInputs.isPrivate && start.privateCallCount > 0`:
+    - If `privateCall.functionSignature.isConstructor == true || privateCall.functionSignature.isCallback == true`:
+        - Revert - only the first call in the kernel recursion can be a constructor or a callback.
+    * Verify the `previousKernelProof` using the `previousKernelVK`
+    * Validate that the `previousKernelVK` is a valid private kernel VK with a membership check:
+        * Calculate `previousKernelVKHash := hash(previousKernelVK);`
+        * Compute `root` using the `previousKernelVKHash`, `previousKernelVKPath` and `previousKernelVKIndex`.
+        * Validate that `root == privateKernelVKTreeRoot`.
+    * Validate consistency of 'starting' and 'previous end' values:
+        - verify that the `start...` values match the `previousKernelProofPublicInputs.end...` equivalents. (As mentioned in the table above, we might be able to just pass one set of inputs to avoid this cross-checking)
+    * Validate consistency of values which must remain the same throughout the recursion (when passed from kernel circuit to kernel circuit):
+        * ensure this kernel circuit's 'constant' public inputs match the `previousKernelProof`'s public inputs.
+            * E.g. old tree roots.
+        - Also ensure that any 'append-only' stacks or arrays have the same entries as the previous kernel proof, before pushing more data onto them!
+
+Verify the next call on the callstack:
+* Verify `start.privateCallStack.length > 0` and (if not already done during the 'Base Case' logic above), pop 1 item off of `start.privateCallStack`.
+* Validate that `privateCall.functionSignature.isPrivate == true` (otherwise this is the wrong type of kernel circuit to be using).
+* Validate that this newly-popped  `privateCallStackItemHash` corresponds to the `privateCall` data passed into this circuit:
+    * Calculate `privateCallPublicInputsHash := hash(privateCall.publicInputs);`
+    * Verify that `privateCallStackItemHash == hash(privateCall.functionSignature, privateCallPublicInputsHash, privateCall.callContext, etc...)`
+    * Recall, the structure of a callstack item:
+    * ```js
+      privateCall = {
+        functionSignature: {
+          contractAddress,
+          vkIndex,
+          isPrivate,
+          isConstructor,
+          isCallback,
+        },
+        publicInputsHash,
+        callContext,
+        isDelegateCall,
+        isStaticCall,
+      }
+      ```
+* Verify the correctness of `(proof, privateCallPublicInputsHash)` using the `vk`.
+* Validate the `vk` actually represents the function that is purportedly being executed:
+    * Extract the `contractAddress` and `vkIndex` from `privateCall.functionSignature`.
+    * Compute `vkHash := hash(vk)`
+    * Compute the `vkRoot` of this function's contract using the `vkIndex`, `vkPath`, and `vkHash`.
+    * Compute the contract's leaf in the `contractTree`:
+      * Let `leafValue := hash(contractAddress, portalContractAddress, vkRoot)`
+    * Compute `contractTreeRoot` using the `contractLeafIndex`, `contractPath` and `leafValue`.
+    * Validate that `contractTreeRoot == constants.oldTreeRoots.contractTree`.
+* Validate consistency of the `privateCall`'s `constant` data with that of the kernel circuit's public inputs (and those of the previousKernelProof). I.e.:
+    * same old tree roots
+    * same timestamp values, etc.
+
+Update the `end` values:
+* Extract the private call's `outputCommitments` and `inputNullifiers`.
+    - If `privateCall.isStaticCall == true`:
+        - Assert that the `outputCommitments` and `inputNullifiers` are empty, since no state changes are allowed for static calls.
+        - NOTE: although it's technically possible to emulate pure reads from the privateDataTree by creating an output commitment with value equal to the input commitment being nullified (i.e. being 'read') - there's no way for the kernel circuit to 'trust' that the logic of the private circuit actually did a pure read and didn't change state (since everything is private).
+    - Else, 'silo' the `outputCommitments` and `inputNullifiers` with the contract address of the callContext: `storageContractAddress := privateCall.callContext.storageContractAddress`:
+        - For each `outputCommitment` in `outputCommitments`:
+            - `siloedOutputCommitment := hash(storageContractAddress, outputCommitment);`
+        - For each `inputNullifier` in `inputNullifiers`:
+            - `siloedInputNullifier := hash(storageContractAddress, inputNullifier);`
+    - Push those values (`siloedOutputCommitments` and `siloedInputNullifiers`) onto `end.outputCommitments`, `end.inputNullifiers`
+    - Also push `callbackNullifier` onto `end.inputNullifiers`, if it exists.
+    * It would be great if these new commitments & nullifiers could be pushed onto the first nonzero element of the `end` lists, so that these `end` lists remain tightly-packed, allowing many more rounds of recursion. Within a circuit, searching for this first nonzero element's index and then pushing to that position will use approx `(3 * 16 + 1) * 256 = 12544` constraints - so `2 * 12544 = 25088` constraints to push both the nullifier and commitment lists.
+        * n = 256
+        * m = 16
+        * `n` checks for the first nonzero entry in the `end` list.
+        * For each of the m nullifiers, loop through the `end` list and conditionally add the nullifier to that position of the `end` list if it's the next nonzero index available. Assuming 3 constraints per iteraction, that's `3mn` constraints.
+        * So `(3m + 1)n` altogether. (Of course it'll end up being way more in practice).
+* Extract the private call's `privateCallStack`, `publicCallStack`, `contractDeploymentCallStack`.
+    - Validate the call contexts of these calls:
+        - For each `newCallStackItem` in `privateCallStack`, `publicCallStack`, `contractDeploymentCallStack` and `partialL1CallStack`.
+            - If `newCallStackItem.functionSignature.contractAddress == 0`:
+                - Then this `0` is understood to be a call to `address(this)`, which cannot be populated by the app's circuit itself.
+                - We must mutate the contract address to be that of the `privateCall`.
+                - Mutation: Set `newCallStackItem.functionSignature.contractAddress = privateCall.functionSignature.contractAddress`
+            - If `newCallStackItem.isDelegateCall == true`:
+                - Assert `newCallStackItem.callContext == publicCall.callContext`
+            - Else:
+                - Assert `newCallStackItem.callContext.msgSender == publicCall.functionSignature.contractAddress`
+                - Assert `newCallStackItem.callContext.storageContractAddress == newCallStackItem.functionSignature.contractAddress`
+    - Validate `partialL1CallStack` and `callbackStack` lengths:
+      - `require(partialL1CallStack.length == callbackStack.length)` - every L1 call must have a callback entry (even if the callbacks are zeroes).
+    - For each `partialL1CallStackItem` in the `partialL1CallStack` (index `i`):
+      - Ensure that the call is being sent to the associated portal contract address, by adding the `portalContractAddress` here:
+        - Let `l1CallStackItem := keccak(portalContractAddress, partialL1CallStackItem)`
+      - Validate `publicCall.callbackStack[i]`:
+        - Let `successCallback = publicCall.callbackStack[i].successCallback`
+        - Let `failureCallback = publicCall.callbackStack[i].failureCallback`
+        - Ensure the contract address of each of the two callbacks matches that of the public call:
+          - TODO: we might actually want to _mutate_ the contractAddress from `0` to the correct address here. `0` initially, because a contract doesn't know its own address, so `0` can mean an instruction to this kernel snark to insert `address(this)`
+          - `require(successCallback.functionSignature.contractAddress == publicCall.functionSignature.contractAddress)`;
+          - `require(failureCallback.functionSignature.contractAddress == publicCall.functionSignature.contractAddress)`;
+        - Calculate the callbackHashes:
+          - Let `successCallbackHash = hash(successCallback.functionSignature, etc...)`
+          - Let `failureCallbackHash = hash(failureCallback.functionSignature, etc...)`
+    - Push the contents of these call stacks onto the kernel circuit's `end.privateCallStack`, `end.publicCallStack`, `end.contractDeploymentCallStack` and `end.l1CallStack`.
+    - Also push the each `{callbackPublicKey, successCallbackHash, failureCallbackHash}` onto `end.callbackStack`.
+    - As per the commitments/nullifiers bullet immediately above, it would be nice if these 'pushes' could result in tightly-packed stacks.
+- Determine whether any values need to be optionally revealed to the 'public world', by referring to the `publicCall`'s booleans:
+    - Let `optionallyRevealedData = {};`
+    - If `privateCall.functionSignature.isConstructor`, set:
+        - `optionallyRevealedData.callStackItemHash = privateCallStackItemHash;`
+        - `optionallyRevealedData.vkHash = vkHash;`
+        - `optionallyRevealedData.emittedPublicInputs = privateCall.publicInputs.emittedPublicInputs;`
+    - If `privateCall.functionSignature.isCallback && exposeCallback`, set:

+        - `optionallyRevealedData.emittedPublicInputs = privateCall.publicInputs.emittedPublicInputs;`
+          - TODO: consider whether we can get rid of the emittedPublicInputs being emitted by a callback. More [here](../contracts/l1-calls.md#more-details).
+    - If `isFeePayment`, set:
+        - `optionallyRevealedData.callStackItemHash = privateCallStackItemHash;`
+        - `optionallyRevealedData.functionSignature = privateCall.functionSignature;`

+        - `optionallyRevealedData.portalContractAddress = portalContractAddress;` // TODO: we need to check this portal contract address is the correct one within this kernel circuit (with a membership check). We need to decide where in L2 this should be stored: either in the contract tree or in the public data tree (e.g. at storage slot 0 for each contract). Argh, it cannot be in the public data tree, because the private kernel circuit cannot access that :heavy_exclamation_mark:
+    - Push the `optionallyRevealedData` onto the `optionallyRevealedData`.
+- Throw an error if any of the stacks is out of room!
+* If `end.privateCallStack.length == 0`, set `end.privateCallCount = 0`, else `end.privateCallCount = start.privateCallCount + 1`
+* Set `isPrivate := true;` (and the others are false)
+* Ensure all unused public inputs (which are _not_ shown in the table above, but will be included in practice so that all kernel snarks have the same public input ABI) are `0`.
+
+
+A private transaction is executed by creating a private Kernel Snark proof over a circuit that contains 1 entry in either `start.privateCallStack` or `start.publicCallStack` or `start.contractDeploymentCallStack` and a valid ECDSA signature.
+
+Execution finishes when `end.privateCallStack.length == 0`. If this condition is not met, the kernel snark proof is recursively fed into the kernel snark circuit and a new proof is made.

+# Public Kernel Circuit
+
+The public kernel circuit has a very similar structure to that of the private kernel circuit.
+
+The public circuit tracks its own call depth. If `start.publicCallCount == 0` , one of two conditions must be met:
+
+* A valid ECDSA signature is provided by a user (where the message is the callStackItemHash). In this case `msg.sender = user`.
+* A valid private kernel proof is provided where `end.privateCallStack.length == 0`.
+
+Public kernel proofs are generated recursively until `end.publicCallStack.length == 0`. At this point the proof can be included within a rollup circuit.
+
+## Private inputs ABI
+
+| Data Type | Description |
+| -------- | -------- |
+| `signature` | ECDSA signature signed by user (if no private kernel proof has been provided && `start.publicCallCount == 0`, otherwise empty) |
+| `start: {` | |
+| `- aggregatedProof` | The current aggregated proof state (if any) |
+| `- publicCallCount` | How many _public_ calls have been recursively executed so far? |
+| `- publicCallStack` | Starting state of public call stack (max depth 64) |
+| `- contractDeploymentCallStack` |  Starting state of contract deployment call stack (max depth 4?) |
+| `- l1CallStack` | Starting state of l1 call stack (max depth 64?) |
+| `- callbackStack` | See breakdown in the public inputs ABI in the next table |
+| `- optionallyRevealedData` | See breakdown in the public inputs ABI in the next table |
+| `- proverRecords` | |
+| `- outputCommitments` | Starting state of commitments to be added to `privateDataTree`.
Notice that a public circuit is allowed to add commitments to the privateDataTree. Imagine, for example, a defi-bridge between private L2 and public L2. Then the rollup processor can complete partial commitments (partial commitments can be added to the _public_ data tree), and the completed commitments can be added straight to the private data tree. |
+| `- inputNullifiers` | Values being passed-through from the private circuit executions (must be kept constant). Although this MUST be kept constant in the public kernel recursion, shouldn't go in the `constants` object of this ABI, because a more important requirement is for _all_ kernel snarks to have the same public inputs layout, so this needs to live here in `start`/`end` instead. There's a check in each kernel snark to ensure arrays are append-only (and hence unchanged at earlier indices), so constant-ness is ensured. |
+| `- publicDataTreeRoot` | The publicDataTree's root _before_ we make any state transitions (as requested in the publicCall being verified within this circuit). |
+| `}` | |
+| `previousKernel: {` | |
+| `- proof` | |

+| `- vk` | The VK that should be used to verify the `previousKernel.proof`. |
+| `- vkIndex` | The leaf index of the `previousKernel.vk`, to accompany the `previousKernel.vkPath` in doing a membership check. |
+| `- vkPath` | We can support multiple 'sizes' of kernel circuit (i.e. kernel circuits with varying numbers of public inputs) if we store all of the VKs of such circuits as vkHashes in a little Merkle tree. This path is the sibling path from the `previousKernel.vk`'s leaf to the root of such a tree. |
+| `}` | |
+| `publicCall: {` | Data relating to the next public callstack item that we're going to pop off the callstack and verify within this snark. Recall we're representing items in the callstack as a `callStackItemHash`. We'll pass the unpacked data here, for validation within this kernel circuit. |
+| `- functionSignature,` | 64-bits (see earlier section) |
+| `- publicInputs: {...},` | Rather than pass in the `publicInputsHash`, we pass in its preimage here (we'll hash it within this kernel circuit). This is _all_ of the data listed in the Public Circuit ABI's table of public inputs (see earlier section). |
+| `- callContext: {...},` |  |
+| `- isDelegateCall,` | |
+| `- isStaticCall,` | |
+| `- proof` | The proof for this item of the callstack. We'll be verifying this within this kernel circuit. |
+| `- vk` | The full verification key of the public call proof that will be verified within this circuit. (I.e. the proof `start.publicCallStack.pop().proof`) |
+| `- vkPath` | The sibling path of the `vk`'s `vkHash` within the aztec contract's 'mini merkle tree'. |
+| `- portalContractAddress` | Needed to reconstruct the contract's leaf of the `contractTree`. |
+| `- contractLeafIndex` | The leaf index of the contracts tree where this contract's vkTree is stored |
+| `- contractPath` | The sibling path from the contract's root (a leaf of the contract tree) to the `oldContractTreeRoot` |
+| `- stateReadPaths: [` | :question: Discussion needed. We might also need to reveal all the bools to the public kernel snark, so that it may filter out data that doesn't need to be revealed to L1. |
+| `- }, ...]` | :question: Should a callStackItemHash contain a salt, to hide the nature of the call? |
+| `- proverRecords` | We need to record info about who generated public proofs and who generated public kernel snarks, so that they may be rewarded for their work. It's not as simple as there being one prover. Proving might be delegated to various people by the rollup processor, so we need to track an array (obvs of some bounded size) with an element for each prover. Each prover record entry in `proverRecords` will be of the form `[proverAddress, totalNumberOfGates]`, where we track the `totalNumberOfGates` this prover has generated proofs over, as an approximation of the work they've done. |
+| `- outputCommitments` | Output state of commitments to be added to `privateDataTree`.

Notice that a public circuit is allowed to add commitments to the privateDataTree. Imagine, for example, a defi-bridge between private L2 and public L2. Then the rollup processor can complete partial commitments (partial commitments can be added to the _public_ data tree), and the completed commitments can be added straight to the private data tree. |
+| `- inputNullifiers` | Values being passed-through from the private circuit executions (must be kept constant). Although this MUST be kept constant in the public kernel recursion, shouldn't go in the `constants` object of this ABI, because a more important requirement is for _all_ kernel snarks to have the same public inputs layout, so this needs to live here in `start`/`end` instead. There's a check in each kernel snark to ensure arrays are append-only (and hence unchanged at earlier indices), so constant-ness is ensured. |
+| `- publicDataTreeRoot` | The root of the public data tree _after_ performing the stateTransitions requested by the publicCall being verified within this circuit.  |
+| `}` | |
+| `constants: {` | |
+| `- oldTreeRoots: {` | |
+| `- - privateDataTree` | must equal the value used in the final private kernel proof |

+## Execution Logic
+
+:heavy_exclamation_mark: It would be ideal if the number of public inputs of a private kernel and public kernel circuit are the same, so that the below base case and recursion case can use the same verification code path.
+
+- `require(previousKernel.publicInputs.isPrivate == true NAND previousKernel.publicInputs.isPublic == true)`
+- `require(previousKernel.publicInputs.isContractDeployment == false`
+- `require(start.publicCallCount == 0)`
+* `require(start.publicCallStack.length > 0)`
+Base case (verifying a private kernel snark):
+*  if `(previousKernel.proof && previousKernel.publicInputs.isPrivate)`
+    - `require(privateCall.functionSignature.isConstructor == false && privateCall.functionSignature.isCallback == false)`:
+        - only the first call in the kernel recursion can be a constructor or a callback.
+    * Verify the (`previousKernel.proof`, `previousKernel.publicInputs`) using the `previousKernel.vk`.
+    * Validate that the `previousKernel.vk` is a valid _private_ kernel VK with a membership check:
+        * Calculate `previousKernelVKHash := hash(previousKernel.vk)`;
+        * Compute `root` using the `previousKernelVKHash`, `previousKernel.vkPath` and `previousKernel.vkIndex`.
+        * Validate that `root == privateKernelTreeRoot`.
+    * Validate consistency of 'start' and 'previous end' values:
+        - verify that the `start...` values match the `previousKernel.publicInputs.end...` equivalents.
+    * Validate consistency of values which must remain the same throughout the recursion (when passed from kernel circuit to kernel circuit):
+        * ensure this kernel circuit's `constant` public inputs match the `previousKernelProof`'s public inputs.
+            * E.g. old tree roots.
+    - Also ensure that any 'append-only' stacks or arrays have the same entries as the previous kernel proof, before pushing more data onto them!
+- else:
+    - This is the first call of the tx.
+    * Require previous kernel data to be empty.
+    * Validate that `start.publicCallStack.length == 1 && start.contractDeploymentCallStack.length == 0 && start.l1CallStack.length == 0`
+        - TBD: to allow the option of a fee payment, we might require `start.publicCallStack.length` to be "1" or "2, where one tx has an `isFeePayment` indicator". We could even allow any number of initial private calls on the stack, but that's a pretty big deviation from the ethereum tx model.
+    * Pop the only (TBD) `publicCallStackItemHash` off the `start.publicCallStack`.
+        - If `publicCall.functionSignature.isConstructor == true`:
+            - then we don't need a signature from the user, since this entire 'callstack' has been instantiated by a Contract Deployment kernel snark (which itself will have been signed by the user).
+            - Set `isConstructorRecursion := true` - This public input will percolate to, and be checked by. the Contract Deployment Kernel Circuit which calls this constructor. This check is required to prevent a person from circumventing the ECDSA signature check by simply setting `isConstructor = true` when making a private call. If this aggregated kernel snark reaches the rollup circuit without this flag being reset to `false` by the Contract Deployment Kernel Circuit (to say "yes, this kernel was indeed a constructor for a Contract Deployment Kernel Circuit"), then the entire tx will be rejected by the rollup circuit.
+        - Else:
+            - Set `isConstructorRecursion := false`
+            * Verify the ECDSA `signature`, with `message := publicCallStackItemHash` and `signer := publicCall.callContext.msgSender`.
+            - Validate the `callContext`. Usually the correctness of a callContext is checked between the `publicCall` and all the new calls it makes (see later in this logic). That means for this 'Base case', those checks haven't been done for this `publicCall` (since there was no prior iteration of this kernel circuit to make those checks).
+                - If `publicCall.isDelegateCall == true || publicCall.isStaticCall == true`:
+                    - Revert - a user cannot make a delegateCall or staticCall.
+                - Else:
+                    - Assert `publicCall.callContext.storageContractAddress == publicCall.functionSignature.contractAddress`
+        - If `publicCall.functionSignature.isCallback == true`:
+            - Set `isCallbackRecursion = true;` - this can only be set in the _first_ call of a recursion.
+            - Assert `l1ResultHash != 0`
+            - Copy over the `publicCall.publicInputs.executedCallback` data to this snark's output: `constants.executedCallback`.
+        - Else:
+            - Set `isCallbackRecursion = false;`
+            - Assert `l1ResultHash == 0`
+- Set `initialPublicDataTreeRoot := start.publicDataTreeRoot`.
+
+
+Recursion (of public kernel snarks):
+* If `previousKernel.publicInputs.isPublic && start.publicCallCount > 0`:
+    - `require(privateCall.functionSignature.isConstructor == false && privateCall.functionSignature.isCallback == false)`:
+        - only the first call in the kernel recursion can be a constructor or a callback.
+    * Verify the `previousKernel.proof` using the `previousKernel.vk`
+    * Validate that the `previousKernel.vk` is a valid _public_ kernel VK with a membership check:
+        * Calculate `previousKernelVKHash := hash(previousKernel.vk)`;
+        * Compute `root` using the `previousKernelVKHash`, `previousKernel.vkPath` and `previousKernel.vkIndex`.
+        * Validate that `root == publicKernelVKTreeRoot`.
+    * Validate consistency of 'start' and 'previous end' values:
+        - verify that the `start...` values match the `previousKernel.publicInputs.end...` equivalents.
+    * Validate consistency of values which must remain the same throughout the recursion (when passed from kernel circuit to kernel circuit):
+        * ensure this kernel circuit's 'constant' public inputs match the `previousKernel`'s public inputs.
+        * E.g. old tree roots.
+
+Verify the next call on the callstack:
+* Verify `start.publicCallStack.length > 0` and (if not already done during the 'Base Case' logic above), pop 1 item off of `start.publicCallStack`.
+* Validate that `publicCall.functionSignature.isPrivate == false` (otherwise this is the wrong type of kernel circuit to be using).
+* Validate that this newly-popped  `publiceCallStackItemHash` corresponds to the `publicCall` data passed into this circuit:
+    - Calculate the `publicInputsHashPreimage`, given the complexity that 'current' public data wasn't known to the caller at the time they made the call:
+        - Include all data from `publicCall.publicInputs`, except for the data documented earlier in the Public Circuit ABI section.
+    * Calculate `publicCallPublicInputsHash := hash(publicInputsHashPreimage);`
+    * Verify that `publicCallStackItemHash == hash(publicCall.functionSignature, publicCallPublicInputsHash, publicCall.callContext, etc...)`
+    * Recall, the structure of a callstack item:
+    * ```js
+      publicCall = {
+        functionSignature: {
+          contractAddress,
+          vkIndex,
+          isPrivate,
+          isConstructor,
+          isCallback,
+        },
+        publicInputsHash,
+        callContext,
+        isDelegateCall,
+        isStaticCall,
+      }
+      ```
+* Verify the correctness of `(proof, publicCallPublicInputsHash)` using the `vk`.
+* Validate the `vk` actually represents the function that is purportedly being executed:
+    * Extract the `contractAddress` and `vkIndex` from `publicCall.functionSignature`.
+    * Compute `vkHash := hash(vk)`
+    * Compute the `vkRoot` of this function's contract using the `vkIndex`, `vkPath`, and `vkHash`.
+    * Compute the contract's leaf in the `contractTree`:
+      * Let `leafValue := hash(contractAddress, portalContractAddress, vkRoot)`
+    * Compute `contractTreeRoot` using the `contractLeafIndex`, `contractPath` and `leafValue`.
+    * Validate that `contractTreeRoot == constants.oldTreeRoots.contractTree`.
+* Validate consistency of the `publicCall`'s `constant` data with that of the kernel circuit's public inputs (and those of the previousKernelProof). I.e.:
+    * same old tree roots
+    * etc.
+
+
+Update the `end` values:
+- Extract the public call's `stateReads`, which will have been populated with current values by the rollup provider (i.e. each transition will be of the form `[storageSlot, current_value`]).
+    - Extract the contract address of the contract being read from, based on the callContext: `storageContractAddress := publicCall.callContext.storageContractAddress`.
+    - For each `stateRead` in `stateReads` (loop index `i`):
+        - Calculate the `stateLeafIndex = hash(storageContractAddress, stateRead.storageSlot)` (this can be thought of as a 'key' in a key:value mapping. The `stateRead.current_value` is the 'value').
+        - Check the `current_value` is correct:
+            - do a membership check with: `leafValue = current_value, leafIndex = stateLeafIndex, siblingPath = stateReadPaths[i]`
+            - Assert that the calculated root equals `start.publicDataTreeRoot`.
+- Extract the public call's `stateTransitions`, which will have been populated with old and new values by the rollup provider (i.e. each transition will be of the form `[storageSlot, old_value, new_value`]).
+    - Extract the contract address to be used for storage, based on the callContext: `storageContractAddress := publicCall.callContext.storageContractAddress`.
+    - Let `tempPublicDataTreeRoot := start.publicDataTreeRoot`
+    - For each `stateTransition` in `stateTransitions` (loop index `i`):
+        - Calculate the `stateLeafIndex = hash(storageContractAddress, stateTransition.storageSlot)` (this can be thought of as a 'key' in a key:value mapping. The `stateTransition.old_value` is the 'value').
+        - Check the old_value is correct:
+            - do a membership check with: `leafValue = old_value, leafIndex = stateLeafIndex, siblingPath = stateTransitionPaths[i]`
+            - Assert that the calculated root equals `tempPublicDataTreeRoot`.
+        - Update the tree with the new_value:
+            - Hash up the tree using `leafValue = old_value, leafIndex = stateLeafIndex, siblingPath = stateTransitionPaths[i]`.
+            - Set `tempPublicDataTreeRoot = the newly computed root`.
+    - Set `end.publicDataTreeRoot = tempPublicDataTreeRoot`
+* Extract the public call's `outputCommitments` (recall: a public circuit can indeed output new commitments, much like the claim circuit). 
+    - If `publicCall.isStaticCall == true`:
+        - Assert that `outputCommitments` is empty, since no state changes are allowed for static calls.
+    - Else, 'silo' the `outputCommitments` with the contract address of the callContext: `storageContractAddress := publicCall.callContext.storageContractAddress`:
+        - For each `outputCommitment` in `outputCommitments`:
+            - `siloedOutputCommitment := hash(storageContractAddress, outputCommitment);`
+    - Push those values (`siloedOutputCommitments`) onto `end.outputCommitments`.
+    * See earlier note on how we can push these values onto the end arrays without gaps (i.e. dynamically)
+* Calculate new data to push to `proverRecords`:
+    - Extract `publicCallProverAddress := publicCall.publicInputs.proverAddress`.
+    - Extract `publicCallNumberOfGates := vk.n`
+    - Extract `previousKernelProverAddress := previousKernel.publicInputs.proverAddress`
+    - Extract `previousKernelNumberOfGates := previousKernel.vk.n`
+    - Below is expensive looping and dynamic pushing within a circuit (O(n^2) stuff). Consider alternatives.
+    - Find in the `proverRecords` array an entry matching `publicCallProverAddress`.
+        - If found: increment their `totalNumberOfGates += publicCallNumberOfGates`.
+        - If not found: push a new record `[publicCallProverAddress, publicCallNumberOfGates]` onto `proverRecords`.
+    - Find in the `proverRecords` array an entry matching `previousKernelProverAddress`.
+        - If found: increment their `totalNumberOfGates += previousKernelNumberOfGates`.
+        - If not found: push a new record `[previousKernelProverAddress, previousKernelNumberOfGates]` onto `proverRecords`.
+* Extract the public call's `publicCallStack`, `contractDeploymentCallStack` and `partialL1CallStack`.
+    - Validate the call contexts of these calls:
+        - For each `newCallStackItem` in `publicCallStack`, `contractDeploymentCallStack`:
+            - If `newCallStackItem.isDelegateCall == true`:
+                - Assert `newCallStackItem.callContext == publicCall.callContext`
+            - Else:
+                - Assert `newCallStackItem.callContext.msgSender == publicCall.functionSignature.contractAddress`
+                - Assert `newCallStackItem.callContext.storageContractAddress == newCallStackItem.functionSignature.contractAddress`
+    - Validate `partialL1CallStack` and `callbackStack` lengths:
+      - `require(partialL1CallStack.length == callbackStack.length)` - every L1 call must have a callback entry (even if the callbacks are zeroes).
+    - For each `partialL1CallStackItem` in the `partialL1CallStack` (index `i`):
+      - Ensure that the call is being sent to the associated portal contract address, by adding the `portalContractAddress` here:
+        - Let `l1CallStackItem := keccak(portalContractAddress, partialL1CallStackItem)`
+      - Validate `publicCall.callbackStack[i]`:
+        - Let `successCallback = publicCall.callbackStack[i].successCallback`
+        - Let `failureCallback = publicCall.callbackStack[i].failureCallback`
+        - Ensure the contract address of each of the two callbacks matches that of the public call:
+          - `require(successCallback.functionSignature.contractAddress == publicCall.functionSignature.contractAddress)`;
+          - `require(failureCallback.functionSignature.contractAddress == publicCall.functionSignature.contractAddress)`;
+        - Calculate the callbackHashes:
+          - Let `successCallbackHash = hash(successCallback.functionSignature, etc...)`
+          - Let `failureCallbackHash = hash(failureCallback.functionSignature, etc...)`
+    - Push the contents of these call stacks onto the kernel circuit's `end.publicCallStack`, `end.contractDeploymentCallStack` and `end.l1CallStack`.
+    - Also push the each `{callbackPublicKey, successCallbackHash, failureCallbackHash}` onto `end.callbackStack`.
+    - As per the commitments/nullifiers bullet above, it would be nice if these 'pushes' could result in tightly-packed stacks.
+- Determine whether any values need to be optionally revealed to the Contract Deployment kernel circuit, or to L1, by referring to the `publicCall`'s booleans:
+    - Let `optionallyRevealedData = {};`
+    - If `publicCall.functionSignature.isConstructor`, set:
+        - `optionallyRevealedData.callStackItemHash = publicCallStackItemHash;`
+        - `optionallyRevealedData.vkHash = vkHash;`
+        - `optionallyRevealedData.emittedPublicInputs = publicCall.publicInputs.emittedPublicInputs;`
+    - If `publicCall.functionSignature.isCallback`, set:
+        - `optionallyRevealedData.functionSignature = publicCall.functionSignature;`
+        - `optionallyRevealedData.emittedPublicInputs = publicCall.publicInputs.emittedPublicInputs;`
+          - TODO: consider whether we can get rid of the emittedPublicInputs being emitted by a callback. More [here](../contracts/l1-calls.md#more-details).
+    - If `isFeePayment`, set:
+        - `optionallyRevealedData.callStackItemHash = publicCallStackItemHash;`
+        - `optionallyRevealedData.functionSignature = publicCall.functionSignature;`
+        - `optionallyRevealedData.emittedPublicInputs = publicCall.publicInputs.emittedPublicInputs;`
+    - If `payFeeFromL1`, set:
+        - `optionallyRevealedData.callStackItemHash = publicCallStackItemHash;`
+    - If `calledFromL1`, set:
+        - `optionallyRevealedData.callStackItemHash = publicCallStackItemHash;`
+        - `optionallyRevealedData.functionSignature = publicCall.functionSignature;`
+        - `optionallyRevealedData.emittedPublicInputs = publicCall.publicInputs.emittedPublicInputs;`
+    - Push the `optionallyRevealedData` onto the `optionallyRevealedData`.
+* If `end.publicCallStack.length == 0`, set `end.publicCallCount = 0`, else `end.publicCallCount = start.publicCallCount + 1`
+* Set `isPublic := true;` (and the others are false)
+* Ensure all unused public inputs (which are _not_ shown in the table above, but will be included in practice so that all kernel snarks have the same public input ABI) are `0`.

+
+## Execution Logic
+
+We'll do a few things in the circuit:
+- Verify the two kernel snarks
+- Merge some arrays from both inputs
+- Check some tree stuff
+- Check the public inputs of both kernel snarks based on the ordering:
+    - `kernelSnarks[0]` happened first
+    - `kernelSnarks[1]` happened second
+
+So:
+- the base rollup circuit's `start` tree data must line up with the `initial...` tree data of `kernelSnarks[0]`.
+- the `end` tree data of `kernelSnarks[0]` must line up with the `initial...` tree data of `kernelSnarks[1]`.
+- the `end` tree data of `kernelSnarks[1]` must line up with the base rollup circuit's `end` tree data.
+
+Here we go...
+
+- For `i in [0, 1]`:
+    - If `kernelSnarks[i].publicInputs.constants.isConstructorRecursion == true`:
+        - Revert. A constructor kernel can only be verified by the contractDeployment kernel snark.
+    - Verify `(kernelSnarks[i].proof, kernelSnarks[i].publicInputs)` against the vk `kernelSnarks[i].vk`.
+    - Validate that the `kernelSnarks[i].vk` is a valid kernel snark of the correct `kernelSnarks[i].kernelType` with a membership check of the relevent kernel snark vk tree:
+        - Calculate `kernelVKHash := hash(kernelSnarks[i].vk)`;
+        - Compute `root` using the `kernelVKHash`, `kernelSnarks[i].vkPath` and `kernelSnarks[i].vkIndex`.
+        - Validate that `root == constants.KernelVKTreeRoot`.
+
+Validate that the callStacks of both kernel snarks were all completed (are all empty):
+- For `i in [0, 1]`:
+    - `require(callCount == 0);`
+    - Require all values of `privateCallStack`, `publicCallStack`, `contractDeploymentCallStack` to be `0`.
+
+Check the old tree roots (that were referred-to by the users' circuits) have actually existed (at some point in history) as the root of their tree:
+- For `i in [0, 1]`:
+    - Check the old private data tree root once existed:
+        - Calculate `root` using: `leafValue: kernelSnarks[i].publicInputs.constants.oldTreeRoots.privateDataTree, leafIndex: membershipWitnesses.oldPrivateDataTreeRoots[i].leafIndex, siblingPath: membershipWitnesses.oldPrivateDataTreeRoots[i].siblingPath`.
+        - `assert(root == start.privateDataTreeRootsTree.root`
+    - Check the old contract tree root once existed:
+        - Calculate `root` using: `leafValue: kernelSnarks[i].publicInputs.constants.oldTreeRoots.contractTree, leafIndex: membershipWitnesses.oldContractTreeRoots[i].leafIndex, siblingPath: membershipWitnesses.oldContractTreeRoots[i].siblingPath`.
+        - `assert(root == start.contractTreeRootsTree.root`
+    - Check the old L1 results tree root once existed:
+        - Calculate `root` using: `leafValue: kernelSnarks[i].publicInputs.constants.oldTreeRoots.l1ResultsTree, leafIndex: membershipWitnesses.oldL1ResultsTreeRoots[i].leafIndex, siblingPath: membershipWitnesses.oldL1ResultsTreeRoots[i].siblingPath`.
+        - `assert(root == start.contractTreeRootsTree.root`
+
+Check the alignment of the start and end states of the two trees which were updated _within the kernel snarks_ (the publicDataTree and the contractTree). This ensures the kernel snarks didn't make any unexpected changes to those trees:
+
+- `start -> kernelSnarks[0]`:
+    - `require(start.publicDataTree.root == kernelSnarks[0].publicInputs.constants.initialPublicDataTreeRoot);`
+    - `require(start.contractTree.root == kernelSnarks[0].publicInputs.constants.initialContractTreeRoot);`
+    - `require(start.contractTree.nextAvailableLeafIndex == kernelSnarks[0].publicInputs.constants.initialNextAvailableContractTreeLeafIndex);`
+- `kernelSnarks[0] -> kernelSnarks[1]`:
+    - `require(kernelSnarks[0].publicInputs.end.publicDataTreeRoot == kernelSnarks[1].publicInputs.constants.initialPublicDataTreeRoot);`
+    - `require(kernelSnarks[0].publicInputs.end.contractTreeRoot == kernelSnarks[1].publicInputs.constants.initialContractTreeRoot);`
+    - `require(kernelSnarks[0].publicInputs.end.nextAvailableContractTreeLeafIndex == kernelSnarks[1].publicInputs.constants.initialNextAvailableContractTreeLeafIndex);`
+- `kernelSnarks[1] -> end`:
+    - `require(kernelSnarks[1].publicInputs.end.publicDataTreeRoot == end.publicDataTree.root);`
+    - `require(kernelSnarks[1].publicInputs.end.contractTreeRoot == end.contractTree.root);`
+    - `require(kernelSnarks[1].publicInputs.end.nextAvailableContractTreeLeafIndex == end.contractTree.nextAvailableLeafIndex);`
+
+Merge input stacks/arrays to create single output stacks/arrays:
+- `assert(l1CallStack == [...kernelSnarks[0].publicInputs.end.l1CallStack, ...kernelSnarks[1].publicInputs..end.l1CallStack]);`
+- `assert(optionallyRevealedData == [...kernelSnarks[0].publicInputs..end.optionallyRevealedData, ...kernelSnarks[1].publicInputs.end.optionallyRevealedData]);`
+- `assert(deployedContractData == [...kernelSnarks[0].publicInputs..end.deployedContractData, ...kernelSnarks[1].publicInputs.end.deployedContractData]);`
+
+
+If either of the kernel snarks was a callback execution, check that their purported L1 Result is correct (i.e. that it exists in the L1 results tree).
+We do this here, in the base rollup circuit rather than the public kernel circuit, because this only needs to be done at most once per tx, so it'd be wasteful to repeat this calc in every kernel recursion. Having said that, the _private_ kernel circuit does also offer this functionality, so that a user may hide which callback they're calling (and even the fact they're executing a callback at all).
+This logic MUST come before the 'nullifier insertion' logic, because we add a new nullifier to the set here.
+- Let `callbackNullifiers = []`
+- For `i in [0, 1]`:
+    - If `kernelSnarks[i].publicInputs.constants.isCallbackRecursion`
+        - `require(l1ResultHash != 0)` to prevent a user executing a callback which refers to a _pending_ result.
+        - Extract `{ l1ResultHash, l1ResultsTreeLeafIndex } = kernelSnarks[i].publicInputs.constants.executedCallback;`
+        - Extract `{ callbackStackItem: { callbackPublicKey, successCallback, failureCallbac } } = membershipWitnesses.executedCallbacks[i];`
+        - Extract the function signature of the callback which was called (this will always be at the 0th position of the optionallyRevealedData):
+            - Let `executedCallbackFunctionSignature = kernelSnarks[i].publicInputs.end.optionallyRevealedData[0].functionSelector`.
+            - `require(executedCallbackFunctionSignature != 0)`
+            - Let `executedCallbackEmittedPublicInputs = kernelSnarks[i].publicInputs.end.optionallyRevealedData[0].emittedPublicInputs`.
+        - If `l1ResultHash != 0` (success):
+            - Check the successCallback's `functionSignature` matches the kernel snark's:
+            - `require(successCallbackHash.functionSignature == executedCallbackFunctionSignature)`
+            - In fact, check the entire successCallbackCallHash
+        - Else:
+            - Check the failureCallbackHash's `functionSignature` matches the kernel snark's:
+            - `require(failureCallbackHash.functionSignature == executedCallbackFunctionSignature)`
+            - In fact, check the entire successCallbackCallHash
+        - `require(callbackPublicKey == 0)`, otherwise this callback should have been processed in the private kernel snark.
+        - Let `callbackStackItemHash := hash(callbackPublicKey, callbackStackItem.successCallbackHash, callbackStackItem.failureCallbackHash)`
+        - Let `leafValue = hash(l1ResultHash, callbackStackItemHash);`
+        - Check membership of the `leafValue` in the `l1ResultsTree` using:
+            - `l1ResultsTreeLeafIndex`
+            - `membershipWitnesses.executedCallbacks[i].siblingPath`
+            - `kernelSnarks[i].publicInputs.constants.oldTreeRoots.l1ResultsTree`
+        - Set `callbackNullifiers[i] := hash(callbackStackItemHash, callbackPrivateKey = 0)` to prevent this callback from being executed again.
+            - We don't include the whole `leafValue` in the preimage of the nullifier, to prevent a user maliciously calling the callback twice: once for 'success' and once for 'fail' (although that shouldn't be possible if the 'L1 results copier' circuit works correctly).
+            - The `callbackPrivateKey` only gets used if the callback is executed privately (in which case all of the checks of this section are done in the private kernel circuit. The private kernel circuit would then toggle the `isCallbackRecursion` to `false`, to hide the fact that it's a callback, and so that this section is skipped within this circuit).
+
+Add new pending callbacks to the l1ResultsTree:
+- Let `pendingResultLeafValues = [];`
+- For `i in [0, 1]`
+  - For each `callbackStackItem in kernelSnarks[i].publicInputs.end.callbackStack`.
+  - Set `pendingResultLeafValues.push( callbackStackItemHash )` ("pendingResult", because "finalisation" of the leaf happens once the L1 results are added in the next rollup).
+- Batch-insert the `pendingResultLeafValues`, using:
+    - `start.l1ResultsTree.nextAvailableLeafIndex`
+    - `start.l1ResultsTree.root` (to reconcile the starting root before adding more leaves)
+    - `end.l1ResultsTree.nextAvailableLeafIndex`
+    - `end.l1ResultsTree.root`
+    - `membershipWitnesses.callbackStackBatch`
+
+
+
+Add the inputNullifiers and outputCommitments to their trees:
+- Merge the arrays from the two input kernel snarks:
+    - Let `inputNullifiers := [...kernelSnarks[0].publicInputs.end.inputNullifiers, ...kernelSnarks[1].publicInputs.end.inputNullifiers]`;
+    - Let `outputCommitments := [...kernelSnarks[0].publicInputs.end.outputCommitments, ...kernelSnarks[1].publicInputs.end.outputCommitments]`;
+
+Nullifiers:
+- Let `inputNullifierLeafIndex := start.nullifierTree.nextAvailableLeafIndex`
+- Let `rootBeforeInsertion := start.nullifierTree.root`
+- For each `inputNullifier` in `inputNullifiers` (index `i`):        
+    - Do a non-membership check, using:
+        - `membershipWitnesses.lowNullifiers[i]` (to validate `rootBeforeInsertion`)
+        - `inputNullifiers[i]` to validate non-membership.
+        - See the hackmd for the new nullifier tree info.
+    - Update all of the `lowNullifiers[i].leafValue.nextValue` and `lowNullifiers[i].leafValue.nextIndex` values, using:
+        - `membershipWitnesses.lowNullifiers[i]` 
+        - `inputNullifiers[i]` to update the 'next' values.
+    - Batch-insert the new `inputNullifiers`, using:
+        - `start.nullifierTree.nextAvailableLeafIndex`
+        - `start.nullifierTree.root` (to reconcile the starting root before adding more leaves)
+        - `end.nullifierTree.nextAvailableLeafIndex`
+        - `end.nullifierTree.root`
+        - `membershipWitnesses.inputNullifiersBatch`
+
+Commitments:
+- Batch-insert `outputCommitments` (and validate start and end tree states) using:
+    - `start.privateDataTree.nextAvailableLeafIndex`
+    - `start.privateDataTree.root` (to reconcile the starting root before adding more leaves)
+    - `end.privateDataTree.nextAvailableLeafIndex`
+    - `end.privateDataTree.root`
+    - `membershipWitnesses.outputCommitmentsBatch`
+
+
+Update the (difficultly-named) trees whose leaves are the roots of historic trees. I.e. add the newly-calculated roots as the 'latest' roots of the historic trees (`privateDataTreeRootsTree`, `contractTreeRootsTree`, `l1ResultsTreeRootsTree`).
+
+- Insert the newly-calculated `end.privateDataTree.root` as a new leaf in the `privateDataTreeRootsTree` using:
+    - `membershipWitnesses.endPrivateDataTreeRoot.siblingPath`
+    - `start.privateDataTreeRootsTree.nextAvailableLeafIndex`
+    - `start.privateDataTreeRootsTree.root`
+    - `end.privateDataTreeRootsTree.nextAvailableLeafIndex`
+    - `end.privateDataTreeRootsTree.root`
+
+- Insert the newly-calculated `end.contractTree.root` as a new leaf in the `contractTreeRootsTree` using:
+    - `membershipWitnesses.endContractTreeRoot.siblingPath`
+    - `start.contractTreeRootsTree.nextAvailableLeafIndex`
+    - `start.contractTreeRootsTree.root`
+    - `end.contractTreeRootsTree.nextAvailableLeafIndex`
+    - `end.contractTreeRootsTree.root`
+
+- Insert the newly-calculated `end.l1ResultsTree.root` as a new leaf in the `l1ResultsTreeRootsTree` using:
+    - `membershipWitnesses.endl1ResultsTreeRoot.siblingPath`
+    - `start.l1ResultsTreeRootsTree.nextAvailableLeafIndex`
+    - `start.l1ResultsTreeRootsTree.root`
+    - `end.l1ResultsTreeRootsTree.nextAvailableLeafIndex`
+    - `end.l1ResultsTreeRootsTree.root`
+
+* Calculate new data to push to `proverRecords`:
+    - Calculate new prover record data from both input kernelSnarks, using the `proverAddress` and `vk` of the kernel snarks' `publicInputs` (see detailed logic in the kernel snarks' 'execution logic' sections).
+    - Push that data onto the `proverRecords` array.

+# L1 Results Copier Circuit
+
+See the [L2 --> L1 calls](../contracts/l1-calls.md#l2----l1-calls) section for motivation.
+
+This circuit copies results of L1 calls (which were executed by the _previous_ rollup) to the `l1ResultsTree` on L2. It will effectively be updated _before_ any other state changes of this next rollup, so that the results are available for txs (callbacks) in this rollup to use.
+
+This is a generalisation of how the root rollup circuit adds defi interaction notes to the defi tree.
+
+> TODO: consider whether we can safely make execution of this circuit _optional_, so that several sequential rollups can be computed in parallel (meaning much faster rollup throughput). I.e. if we don't force the very next rollup to copy over results data, then the very next rollup (and the one after that, and so on) can start to be computed before the L1 txs are finalised, for mega fast throughput. Every now and then, a rollup provider could include an 'L1 results copy proof'... we just need to incentivise it so that copying actually happens, whenever possible.
+
+> Note: I've separated this circuit for ease of reading, and because (as the above note suggests) we might not need to do this copying for _every_ rollup.

+
+## Execution Logic
+
+- `assert(l1Results.length == pendingResultLeafValues.length)`.
+- Calculate the 'subroot' of the batch of 'pending' leaves (using `pendingResultLeafValues`) before updating them.
+- Recalculate the `start.l1ResultsTree.root` using the calculated subroot and the membership witness `subtreeMembershipWitness.siblingPath` and `start.l1ResultsTree.firstPendingResultLeafIndex`, and assert that the calculated root matches `start.l1ResultsTree.root`.
+  - This step confirms that the pending leaf hashes (`pendingResultLeafValues`) are correct.
+- 'Finalise' each pending leaf:
+  - Let `updatedLeaves[i] := hash(l1Results[i].l1ResultHash, pendingResultLeafValues[i])`
+  - Note: `l1ResultHash = 0` for any failed L1 calls.
+- Update the tree with the batch of completed leaves using the `subtreeMembershipWitness.siblingPath` and `start.l1ResultsTree.firstPendingResultLeafIndex`.
+- Let `end.l1ResultsTree.firstPendingResultLeafIndex = start.l1ResultsTree.firstPendingResultLeafIndex + l1Results.length`
+- Hash all of the results (using the expensive sha256 hash) so that it may be checked on-chain:
+  - `l1ResultsHash = sha256(...l1Results.map(r => r.l1ResultHash));`

+
+
+## Execution Logic
+
+We'll do a few things in the circuit:
+- Verify the two input ROLLUP snarks
+- Merge some arrays from both inputs
+- Check the public inputs of both rollup snarks based on the ordering:
+    - `rollupSnarks[0]` happened first
+    - `rollupSnarks[1]` happened second
+    - I.e. the `end` data of `rollupSnarks[0]` must line up with the `start` data of `rollupSnarks[1]`
+
+Here we go...
+
+- Validate that either both inputs are a BASE snark or both inputs are a MERGE snark. You can't mix the two.
+    - `assert((rollupSnarks[0].rollupType == 'base' && rollupSnarks[1].rollupType == 'base') ^  (rollupSnarks[0].rollupType == 'merge' && rollupSnarks[1].rollupType == 'merge')`:
+- For `i in [0, 1]`:
+    - Verify `(rollupSnarks[i].proof, rollupSnarks[i].publicInputs)` against the vk `rollupSnarks[i].vk`.
+    - Validate that the `rollupSnarks[i].vk` is a valid base/merge snark:
+        - Let `vkHash := hash(rollupSnarks[i].vk)`
+        - If `rollupSnarks[i].rollupType == 'base'`:
+            - `assert(vkHash == constants.baseRollupVKHash)`
+        - Else (`rollupSnarks[i].rollupType == 'merge'`):
+            - `assert(vkHash == constants.mergeRollupVKHash)`
+
+Ensure constants are kept constant.
+- Assert that all items in `constant` are the same between the two input rollup snarks:
+    - `assert(rollupSnarks[0].publicInputs.constants == rollupSnarks[1].publicInputs.constants)`
+- Assert that the input `constant` are the same as the output `constant`
+    - `assert(rollupSnarks[0].publicInputs.constants == constants)`
+
+Check that the `end` data of `rollupSnarks[0]` lines up with the `start` data of `rollupSnarks[1]`
+- `assert(rollupSnarks[0].end == rollupSnarks[1].start)`
+
+
+Merge input stacks/arrays to create single output stacks/arrays:
+- `assert(l1CallStack == [...rollupSnarks[0].publicInputs.l1CallStack, ...rollupSnarks[1].publicInputs.l1CallStack]);`
+- `assert(optionallyRevealedData == [...rollupSnarks[0].publicInputs.optionallyRevealedData, ...rollupSnarks[1].publicInputs.optionallyRevealedData]);`
+- `assert(deployedContractData == [...rollupSnarks[0].publicInputs.deployedContractData, ...rollupSnarks[1].publicInputs.deployedContractData]);`
+
+* Calculate new data to push to `proverRecords`:
+    - Calculate new prover record data from both input rollupSnarks, using the `proverAddress` and `vk` of the rollup snarks' `publicInputs` (see detailed logic in the kernel snarks' 'execution logic' sections).
+    - Push that data onto the `proverRecords` array.

+# Rollup circuit
+
+Takes two snarks, checks they're correct, and does a 'subtree' of state updating for the various trees. Eventually, 2^k kernel snarks will have been verified in a 'rollup tree' of height k, where the root of the rollup tree is a single rollup snark representing 2^k transactions.
+
+There are two kinds of rollup circuit:
+- 'Base' rollup circuit: Verify two kernel snarks.
+- 'Merge' rollup circuit: Verify two rollup snarks (can be either two 'base' snarks or two 'merge' snarks), 'merging' them into 1 rollup snark.

+# Deployment
+
+Let's suppose our aztec contract will have 3 circuits (plus constructor circuits): deposit, transfer, withdraw.
+
+> In reality these can be a single circuit, much like our join-split circuit, but we'll split it into 3 to show off more machinery of aztec 3.0. Suppose the proving keys and verification keys of these circuits have been generated and we're ready to deploy our aztec contract to Aztec 3.0.
+
+## Private Constructor
+
+See [here](../../architecture/contracts/deployment.md#private-constructor) for background.
+
+In this example, we don't need to initialise any private states, so won't be using the private constructor.
+
+## Public constructor
+
+Let's have a think about Aztec 2.0 and what public states are initialised and tracked for the 'zk.money ERC20' functionality:
+- `userPendingDeposits[] (mapping)`
+- `depositProofApprovals[] (mapping)`
+- `supportedAssets[]`
+- `DEFAULT_ERC20_GAS_LIMIT = 75000;`
+- `assetGasLimit[] (mapping)`
+
+Since Aztec 3.0 will be agnostic to applications, we won't be able to store these states in the RollupProcessor contract anymore. So these app-specific states will need to either be stored in the aztec contract's portal contract, or in the L2 contract (in the publicDataTree). Both options are possible.
+
+The `userPendingDeposits, depositProofApprovals` will both start out as empty mappings, so don't need to be initialised in the public constructor. We'll probably also store these on-chain in the L1 portal contract - another reason we won't be initialising them in this constructor.
+
+The `supportedAssets, DEFAULT_ERC20_GAS_LIMIT, assetGasLimit` array _could_ be prepopulated with some values in the constructor, if we wish for these values to be stored in the aztec L2 publicDataTree, instead of in the L1 portal contract.
+
+To show off as much machinery as possible, let's store `supportedAssets` in the publicDataTree and initialise it in the constructor. The other two gas-related values I'll ignore for now, since 'gas limit' stuff still needs some thinking.
+
+:question: TODO: understanding gas limits for portal contract interactions is a complicated thing to spend time thinking about. The rollup provider really needs to know these limits before they process the rollup, in order to gauge their expected profits.
+
+This example public constructor will simply be a Public Circuit (which follows the Public Circuit ABI) which sets the value of `supportedAssets`. Before we can set this value, we need to know its `storageSlot` in our new contract.
+
+[Storage slots in Solidity](https://docs.soliditylang.org/en/v0.8.9/internals/layout_in_storage.html) are assigned based on the order variables are declared (with a few caveats for complex types). Aztec 3 is a bit more complicated, because storage is split across 3 places:
+- On chain storage in the Portal Contract
+- Public L2 storage in the publicDataTree (account-based storage model).
+- Private L2 storage in the privateDataTree (UTXO storage model).
+
+In this example, things will be stored as follows:
+
+- Portal contract:
+    - `userPendingDeposits[] (mapping)`
+    - `depositProofApprovals[] (mapping)`
+    - ~~`DEFAULT_ERC20_GAS_LIMIT = 75000;`~~ For simplicity, we'll ignore this here.
+    - ~~`assetGasLimit[]`~~ - Fees & gas limits are tricky. I'll ignore for now.
+- publicDataTree
+    - `supportedAssets[]` - publicDataTree (for example's sake)
+- privateDataTree
+    - Join-split value notes are a representation of a user's `balance` (in ERC20 terms).
+    - The ERC20 notion of a `balances[]` mapping can be converted into a UTXO-friendly notion for the privateDataTree. Each user's balance is 'partitioned' across set of commitments. The sum of a user's (not-yet-nullified) commitments' values is understood to represent `balances[userAddress]`. 
+
+
+We're only considering writes to the publicDataTree in the public constructor. So what storage slots will be used in the tree?
+
+The 0th storage slot of every contract are reserved (in the current spec) for:
+0. The leafIndex of a contract's vkRoot in the contractTree.
+
+So, `supportedAssets` can start at `storageSlot = 1`. It's a dynamic array, so we can perhaps copy Ethereum's method for deriving storage slots:
+
+- The length of the array can be stored at `storageSlot = 1`.
+- The `i`th index of the array can be stored at `storageSlot = hash(1) + i`.
+
+Suppose we wish to support 3 assets at the beginning: ETH, DAI, WBTC with asset_id values `0, 1, 2` resp.
+
+Then there are **two** `stateTransitions` for the publicDataTree which the public constructor circuit will expose (via the ABI):
+- `[storgeSlot, oldValue, newValue]`:
+    - `[hash(1) + 1, 0, 1]` for (`supportedAssets[1] = 1;`)
+    - `[hash(1) + 2, 0, 2]` for (`supportedAssets[2] = 2;`)
+
+Notice: we don't need to expose a state transition for ETH's asset_id, because it's intended value is `0`.
+
+Here's the public constructor's nonzero public inputs (refer to the Public Circuit ABI for the rest):
+
+```js
+customPublicInputs,
+customPublicOutputs,
+stateTransitions: [
+    [hash(1) + 1, 0, 1],
+    [hash(1) + 2, 0, 2],
+],
+```
+
+(The other public inputs aren't shown, because they're either 0, or global stuff like block timestamps).
+
+> Note: although we can specify a recommended storage layout (which Noir will use), there's nothing technically stopping an app from deciding upon its own storage layout rules. Contracts' storage slots are siloed by hashing with the contract address (see the spec).
+
+
+The `publicConstructorCallstackItem` looks like:
+
+```js
+publicConstructorCallstackItem: {
+  functionSignature: concat(
+      contractAddress,
+      vkIndex = 0, // Constructor vks won't be added to the contract's vkTree.
+                   // This `0` is treated as 'null' when `isConstructor = true`.
+      isPrivate = false,
+      isConstructor = true,
+      isCallback = false,
+  ),
+  publicInputsHash, // hash of public constructor’s public inputs (see earlier section)
+  callContext,
+  isDelegateCall,
+  isStaticCall,
+}
+```
+
+## L2 contract address
+
+Much like Ethereum's create2, L2 contract addresses are specified deterministically:
+
+`newContractAddress := hash(deployerAddress, salt, vkRoot)`
+
+`deployerAddress` can be a user or another contract.
+
+
+
+## L1 Portal Contract
+
+Refer to the [appendix](./appendix/portal-contract.md) for example pseudocode.
+### Motivation
+
+We need a way of depositing erc20 tokens into a shield contract (an L1 contract which holds the erc20 tokens in escrow whilst they're transferred privately via L2). With Aztec 1.0 & 2.0, the RollupProcessor contract served as the escrow contract, since there was only one application (zk-money). But for Aztec 3.0, we need to _silo_ the funds held in escrow on behalf of each L2 aztec contract. Why?
+
+Imagine two similar erc20-shielding aztec contracts get deployed (by different developers) to Aztec 3.0. The contracts are both composed of deposit, transfer and withdraw circuits. Suppose one of the developers is malicious, and put a backdoor into their withdraw circuit to allow them to withdraw 'infinite' L1 tokens that are held in escrow. Then if all of the L1 funds of both L2 contracts were held in a single pool, the malicious dev could withdraw them all. So we definitely need L1 funds to be siloed for each L2 contract.
+
+Why don't we track the siloed funds of the different L2 contracts in the RollupProcessor, still? Because Aztec 3.0 won't just support erc20 shielding. It'll support unlimited use cases, where different L2 contracts will want to manage different L1 states (not necessarily token balances). Therefore we'll put the onus of developing the logic of managing L1 states in the hands of the aztec contract developers. We'll allow devs to deploy an L1 'portal contract' which interacts with other L1 Ethereum contracts and manages L1 state for a particular L2 aztec contract. "Portal" because it links L2 & L1.
+
+Note: portal contracts will be able to make calls to _any_ L2 function. But an L2 function will only be able to make calls to its portal contract; an L2 function cannot call other L1 contracts directly, because it doesn't have an L1 address. That's a nice way of thinking about Portal contracts actually - they provide an L1 address through which calls to other L1 contracts can be made.
+
+### Portal Contract Deployment
+
+See [here](../../architecture/contracts/deployment.md#l1-portal-contract-address) first.
+
+Let's assume option 2 is available to us for this example. The deployer (the dev who's deploying this L2 contract) writes an L1 Portal Contract to handle calls to/from L2. The developer compiles this portal contract (along with constructor arguments) into bytecode. The address of the portal contract can be determined in advance using CREATE2.
+
+```js
+portalContractAddress = keccak256(0xff, deployingAddress, salt, keccak256(bytecode))[12:]
+```
+
+> Notice there's a constructor argument in the [portal contract example](./appendix/portal-contract.md), just to show off as much machinery as possible. We didn't really need this, because the Rollup Processor's address can be accessed via `msg.sender`. 'Bytecode' is understood to include the contructor arguments of a function. I.e. let bytecode be `abi.encodePacked(bytecode, abi.encode(args))`.
+
+_Somehow_ (TODO) the deployer deploys the Portal Contract, and maybe registers it with the RollupProcessor. We need to prevent front-running of the Portal Contract address, whereby an attacker links the wrong L2 contract with the intended Portal Contract (TODO).
+
+
+## Putting it all together and deploying the contract
+
+The dev will:
+- Write circuits in Noir
+- Write Portal Contract
+- Write loads of code (TypeScript probably) to build their app.
+- Send a tx to deploy a contract to the rollup provider.
+    - ```js
+      call = {
+          publicInputs: {
+              // Constructor functions
+              privateConstructorPublicInputsHash,
+              publicConstructorPublicInputsHash,
+              privateConstructorVKHash,
+              publicConstructorVKHash,
+
+              // L2 contract address (create2-like)
+              contractAddress,
+              vkRoot,
+
+              // Distributing L2 contract data
+              circuitDataKeccakHash,
+
+              // Deploying an L1 Portal Contract
+              portalContractAddress,
+          },
+          callContext, // not needed?
+      }
+      ```
+      (the preimages of all these hashes will also need to be sent, so they may be fed in as private inputs to the contract deployment kernel snark).
+- If there's a private constructor, the dev will need to execute that constructor circuit in their client and 'wrap' it in a private kernel snark proof. Then send that kernel proof to the rollup provider too (probably in the same send as above).
+- The rollup provider will need to execute any public calls and public kernel snark recursions if that private call made any public calls.
+- If there's a public constructor, the rollup provider will need to execute that and 'wrap' it in a public kernel snark.
+- The rollup provider will then execute the Contract Deployment Kernel Circuit and generate a proof.
+    - This circuit validates both constructor kernel snarks;
+    - Then adds the contract data to the tree.
+- Then that proof will be fed into the Base Rollup Circuit...
+- ... which will then be fed into the Merge Rollup Circuit...
+- ... which will eventually be sent to the RollupProcessor contract.
+- The RollupProcessor might store a mapping between the Portal Contract's address and the Contract's address.

+# Deposit
+
+
+Refer to the [example portal contract](./appendix/portal-contract.md) and [example rollup contract](../erc20/appendix/rollup-processor.md) when reading this section.
+
+
+A 'deposit' is an example of an [L1 function making a call to an L2 function](../../architecture/contracts/l1-calls.md#l1----l2-calls). A user might not have any money on L2 yet, so we allow for L2 fees to be paid via L1.
+
+## High-level flow:
+
+- User generates inputs for an L2 contract's `deposit` function.
+- User calls `PortalContract.deposit`
+  - Portal Contract stores some stuff.
+- Portal Contract calls Rollup Processor.
+  - Rollup Processor stores more stuff.
+- User generates a proof of the L2 `deposit` function.
+- The `deposit` function emits an event via the `emittedPublicInputs` field.
+- The proof gets added to a rollup.
+- The Rollup Processor receives the rollup and is able to identify and extract info from functions which were 'called by L1 functions'.
+- The Rollup Processor checks the `emittedPublicInputs` against the previously-stored on-chain stuff.
+- A callback function calls the Portal Contract.
+- The Portal Contract changes 'pending' states to finalised (or deletes them).
+- Done.
+
+## Slightly less high-level flow
+
+- User calls `deposit` in the Portal Contract.
+- Money is transferred-to and held by the Portal Contract, in escrow.
+- An L2 circuit must also be executed as an off-chain counterpart to this on-chain deposit, in order to create a private note.
+- The Portal Contract makes a call to the RollupProcessor's `callL2AndPayFee` function.
+- An [`l2CallHash`](../../architecture/contracts/transactions.md#callstackitemhash) representing a call to the L2 circuit is send to the RollupProcessor to store temporarily, until the L2 function is executed.
+- A `callback` function will also be given to the RollupProcessor, for it to call once the L2 circuit has been executed. This callback will call a function of any other L1 contract.
+  - In our example, the callback will call the Portal Contract's `depositCallback` function.
+- Once the L2 circuit is executed, it will be added to a rollup, and the rollup will be submitted by the rollup provider to `RollupProcessor.processRollup`.
+- The RollupProcessor will be able to identify from the rollup calldata any 'event data' emitted by functions which were 'called' by L1.
+  - In this example, the RollupProcessor will be able to extract the `l2CallHash`, `functionSignature`, and `emittedPublicInputs` of the L2 'deposit' circuit.
+- The `l2CallHash`, `functionSignature`, and `emittedPublicInputs` will all be validated against what was previously stored when the L1 `deposit` function was called.
+  - In particular, the `emittedPublicInputs` of this example's 'deposit' circuit will contain the `amount` deposited, as a way of reconciling the L1 call with the L2 call. It might also contain the `msg.sender`.
+- If all of the checks reconcile, then the rollup provider will be paid a fee (if one was provided as part of the initial L1 call).

+# Withdraw
+
+Withdrawal is an example of a [L2 --> L1 call](../../architecture/contracts/l1-calls.md#l2----l1-calls). A user wants to nullify a private note on L2, and then be transferred ERC20 tokens on L1.
+
+- The user generates a 'withdraw' proof. `withdraw` is a private circuit, because it must nullify a private state.
+- The `withdraw` function nullifies an `amount` owned by the caller.
+- Since it's an L2-->L1 call, the `withdraw` function _does_ reveal select information.
+  - It adds an `l1CallStackItem` to its `l1CallStack`.
+    - This `l1CallStackItem` includes the function selector of the L1 function, as well as an encoding of the arguments to be passed to the function. In particular, two arguments for this example will be an `amount` and a `recipient`.
+  - It can add callbacks, which may be executed depending on the outcome of the L1 function.  
+    - In this example, the outcome will either be:
+      - success: the money is transferred; or
+      - fail: the L1 tx failed.
+    - We don't need a 'success' callback in this example. If the money is successfully transferred, nothing else needs to happen on L2 after the L1 call succeeds (the money has already been nullified on L2).
+    - We add a 'failure' callback to reinstate the private value note containing the `amount`, if the L1 tx fails.
+      - This failure callback can either be a public function or private, depending on the developer's preferences. It can be public, since the 'amount' and 'recipient' are already public knowledge by this point. But it could also be private, which would then allow the user to hide that the callback has even been executed.
+        - In particular, in this example, the `customPublicInputs` will need to contain the `amount` and maybe also the `recipient`, as a way of forcing the callback to only reinstate the correct amount to the correct user.
+- Recall that the initial call to L1 must go via the Portal Contract
+  - ...So the Portal Contract will receive a call from RollupProcessor.sol
+  - If successful, it will return some result data (of variable size), and the RollupProcessor will sha256 hash this data (the amount of data to hash might need to be bounded to prevent griefing attacks).
+    - The sha256 hash will be emitted as an L1 result (along with all other L1 results).
+  - If the call fails and it doesn't return data, the RollupProcessor will register an 'L1 Result Hash' of `0`.
+- The RollupProcessor with sha256 all result hashes to get a single L1ResultsHash (plural name).
+- In the next rollup, the rollup provider will be _forced_ to add each L1ResultsHash to the l1ResultsTree. ('Forced', because the RollupProcessor will check the L1ResultsHash when the next rollup is submitted).
+- The previously-stored callback functions can then be executed - either the success or failure callback, depending on the result.
+  - Each callback function exposes the `callbackCallHash` and an `l1ResultHash`. Both of these get checked against the previously-stored data to ensure the callback is responding in a valid way to the result.

+# About
+
+- This spec is very much a work in progress. It will change many times between now and deployment.
+- Much of this document is to aid development and hence is _very_ detailed, so that things which have been thought about aren't forgotten. The detail might make some sections unreadable (e.g. execution logic bullet points).
+- It's such a big document, that there will be mistakes - please ask & we can correct any you see :)
+- All constants in this spec are somewhat arbitrarily chosen, as the architecture must be implemented and performance measured to determine optimal values.
+- Stuff relating to fees and attributing 'work done' by provers in the form of 'proverRecords' is only half thought-out. It needs more work, so skim read it for now.
+# Goals of Aztec 3
+
+- Private L2
+  - General-purpose, private smart contracts.
+- Public L2
+  - Cheaper public state transactions than interacting with L1.
+- Interacting with Ethereum's L1 still supported (and required for many use cases).
+
+> Whenever we refer to 'contract' in this document, we'll be referring to an Aztec 3 L2 contract (which may comprise both public and private functions). If we're talking about an Ethereum contract, we'll explicitly say something like 'Ethereum contract' or 'L1 contracct' or 'Portal contract'.

+# Extremes
+
+This is all investigative.
+
+This section sets out (in non-Noir pseudocode) what Noir functions might look like in two extremes:
+(TODO: feel free to update these to Noir syntax)
+-  Extreme 1: Noir knows all about the architecture of Aztec 3, and so can abstract all of the 'inner workings' of Aztec 3 away from the developer.
+-  Extreme 2: Noir doesn't know any of the inner workings of Aztec 3, and so the developer would have to manually write circuits which exactly conform to Aztec 3's architecture.
+
+We'll probably end up somewhere in the middle.
+
+## Examples covered:
+
+- [incrementation of private state _not_ owned by caller](./incr-private-not-owned.md)
+  - Note: if a private state is _not_ owned by the caller, then this is the only mutation that can safely be done on that state. This is because the caller cannot know the current value of the state they're modifying. So they can only safely add to it. (Unless we relax some design constraints, perhaps).
+- [incrementation of private state owned by the caller](./incr-private-owned.md)
+- [decrementation of private state owned by the caller](./decr-private-owned.md)
+- [editing a public state](./edit-public.md)
+- [reading a public state](./read-public.md)
+- [calling a private function of a different contract](./call-private.md)
+- [calling a public function of a different contract](./call-public.md)
+- [calling a public function from a private function of the same contract](./call-public-same.md)
+- [calling an L1 function](./call-l1.md)
+- [emitting an 'event'](./emit-event.md)
+- [executing a function as a callback, following an L1 result](./callback.md)
+- [deploying a contract from a private/public function](./deploy-contract.md)
+- [new contract constructors]()
+- ['globally' available variables](./global-vars.md)

+There are a few things which have special meaning, or are global 'blockchain' states like:
+- `msg_sender`
+- `min_timestamp`
+- `block.timestamp`
+- `block.number`

Hence any private args can safely be put here, which enables private circuits to call other private circuits, and pass private data to them. To reveal data to the 'public world', either call a public function or emit an event. |

 | `emittedPublicInputs` | Public inputs which will be revealed to the 'public world' (L1 or L2). E.g. allowing certain inputs to be more-easily extracted by the RollupProcessor contract (rather than having to unpack this vast ABI object of inputs, which would cost too much hash-wise). An example of its usefulness is passing a value from L1 to L2 when doing an L1->L2 tx (see 'deposit' example in the other doc). TODO: consider whether this could be a single value, for simplicity. It could be a hash of data if more values need to be exposed. If so, we'll rename to `emittedPublicInputsHash`. |
-| `executedCallback: {` | Populated if this circuit is a callback, so that the purported L1 Result to which this circuit is responding can be validated against the l1ResultsTree. |
-| `- l1ResultHash`, | If this function is a callback function, following some L1 call, then it needs to expose the `l1ResultHash` to ensure the callback is actually using data emitted by L1. The preimage of the `l1ResultHash` will need to be passed in as private inputs to the circuit. Note: the `l1ResultHash` MUST be computed with a sha256 hash, because that's what the RollupProcessor will have used. This is unfortunate, as it forces apps to adhere to a specific calculation within their circuits. |

DISAGREE NOW - we don't need to calcualte this within the app circuit: we can just hash the custom_public_inputs and compare that hash against the L1ResultHash. |

  • `emittedPublicInputs` - so that the rollup provider can validate the amount they'll be paid (they'll need to be provided with the underlying public inputs separately, to validate the hash).
 |
-| `bool payFeeFromL1`| Provides a way of paying for private L2 function execution from L1 (the RollupProcessor.sol could provide the interface for ETH or ERC20... but we could generalise this by somehow pointing to a particular 'other' payment L1 contract state?). "Submit on-chain the callHash and state a fee (in L1 currency) for the L2 tx, and then when the L2 tx is executed, the rollup provider may redeem the previously-published fee". 

  Notifies the kernel circuit that the following public inputs of this private circuit MUST be revealed to the public kernel circuit:
  • `callHash` - no other data is needed (in order to allow the user to keep the function they've actually executed private).
 |

-| `bool calledFromL1` | If the L1 contract wants to call a specific L2 circuit, then the function signature needs to be revealed on-chain so that it can be checked that the correct, intended function was executed. 

 Notifies the private kernel circuit that an L1 contract wants to call this specific private L2 circuit, and so the following MUST be revealed to the public kernel circuit: 
  • `functionSignature` - needed so the L1 contract can confirm the intended function was executed on L2. Although a callHash contains the functionSignature, the L1 contract wouldn't (cheaply) be able to unpack the callHash. So we expose the function signature as well to keep costs down. Although this leaks the function which was called, there's no way around that; this is an L1 -> L2 call after all.
  • `callHash` - used as a 'lookup' key. The RollupProcessor will store this `callHash`, and await an L2 tx with this `callHash` before triggering a callback to the L1 contract which made this L1 -> L2 call in the first place.
  • `emittedPublicInputs` - needed so that a set of values can be emitted by an L2 function and exposed to L1. It would be too expensive to unpack the callHash and extract all of the custom public inputs of a circuit. This is much cheaper, and is very similar to how the EVM exposes only a few values (via event emissions) to JavaScript (for example).
 

 We need this convoluted process, because the RollupProcessor has to be _sure_ an L1 fee has been set-aside for them, before they add any corresponding L2 states. |

It would be too expensive to unpack the callHash and extract all of the custom public inputs of a circuit. This is much cheaper, and is very similar to how the EVM exposes only a few values (via event emissions) to JavaScript (for example).
 

 We need this convoluted process, because the RollupProcessor has to be _sure_ an L1 fee has been set-aside for them, before they add any corresponding L2 states. |
 | Global vars: | |
-| `minTimestamp` | a timestamp value that must be exceeded when the block containing this txn is mined |
+| *`minTimestamp` | a timestamp value that must be exceeded when the block containing this txn is mined |
 
 Apart from the public input API, the structure of a private contract circuit is  undefined by the Aztec 3 architecture.

     - We don't need a 'success' callback in this example. If the money is successfully transferred, nothing else needs to happen on L2 after the L1 call succeeds (the money has already been nullified on L2).
     - We add a 'failure' callback to reinstate the private value note containing the `amount`, if the L1 tx fails.
       - This failure callback can either be a public function or private, depending on the developer's preferences. It can be public, since the 'amount' and 'recipient' are already public knowledge by this point. But it could also be private, which would then allow the user to hide that the callback has even been executed.
-        - In particular, in this example, the `customPublicInputs` will need to contain the `amount` and maybe also the `recipient`, as a way of forcing the callback to only reinstate the correct amount to the correct user.
+        - In particular, in this example, the `customPublicInputs` to the callback will need to contain the `amount` and maybe also the `recipient`, as a way of forcing the callback to only reinstate the correct amount to the correct user. Alternatively, the public input could have been the replacement commitment itself, which could have been created by the withdrawal circuit.
 - Recall that the initial call to L1 must go via the Portal Contract
   - ...So the Portal Contract will receive a call from RollupProcessor.sol
   - If successful, it will return some result data (of variable size), and the RollupProcessor will sha256 hash this data (the amount of data to hash might need to be bounded to prevent griefing attacks).

+
+Contains all ABIs for use by:
+- Test app circuits
+- Kernel circuits
+- Rollup circuits
+
+All ABIs are generalised by an `NCT` template parameter (meaning `NativeOrCircuitTypes`). `NCT` can be either `plonk::stdlib::types::NativeTypes` or `plonk::stdlib::types::CircuitTypes` for some `Composer`. The idea being, there's a single implementation of every struct/class for native and circuit types. NativeType structs can be switched to CircuitType with the `to_circuit_type()` method.

+# aztec3::circuits::apps
+
+All code in this dir is for:
+- Demonstrating how our users' (developers) apps will need to be written, in terms of:
+    - Public inputs
+    - Commitment/nullifier creation (recommendations)
+    - Function calls
+    - Everything from the 'Noir Examples' section of the Aztec3 book.
+- To help illustrate ideas to the Noir team
+- To allow test app circuits to be mocked-up as quickly and easily as possible
+
+## Private State Code
+
+This is some complex code, which attempts to abstract-away stuff to do with creating commitments, nullifiers, and Aztec3 public input ABIs. All that, so that test app circuits can be mocked-up without too much faff. Some explanation is needed:
+
+```

+     |                     |___private_state_var (fr state)

+     |                        |___private_state_note_preimage
+     |                                       |
+     |                                       |___ preimage members are std::optional
+     |                                            so that partial commitments can be
+     |                                            created in one tx, and completed in
+     |                                            a later tx.
+     |
+     |___commitments
+     |___nullifiers      once all notes have been created by the circuit, we can
+                         `finalise()` the state_factory. This will figure out whether
+                         we need more:
+                           - dummy nullifiers (to use as input_nullifiers to
+                             commitments).
+                         Only at this stage are the commitments (and partial commitments)
+                         and nullifiers computed.

+# aztec3::circuits::oracle
+
+When Aztec3 makes a call to a circuit executor (such as Noir or the test apps in aztec3/circuits/apps/test_apps), we don't pass _all_ public inputs when calling the circuit; only the `custom_public_inputs` inputs are sent initially.
+
+Why?
+
+This has two main benefits:
+
+- We only need one implementation of the circuit's logic: the circuit itself. We don't need to implement a separate native version of the circuit to 'predict' what commitments/nullifiers and other values will need to ultimately become inputs to the circuit.
+- There are occasions where it's difficult to predict the inputs required in advance. E.g. if a circuit_1 makes a call to another circuit, circuit_2, at some other contract_address, but that address is calculated within the body of circuit_1. We'd need to independently deduce the address which would be called so that we could grab the correct contract_address, VK, vkIndex, proving key (etc) from the DB.
+
+Instead, we provide an oracle to the circuit executor when we call it. As the circuit is executed, it'll occasionally reach points where it needs more input data. The circuit executor can query the oracle (the Aztec3 node) for more data. The oracle can grab data from its DB and return it the circuit executor. The circuit executor can then convert the data into witnesses and continue with some more of the circuit's execution.

         - If `privateCall.functionSignature.isConstructor == true`:
             - then we don't need a signature from the user, since this entire 'callstack' has been instantiated by a Contract Deployment kernel snark (which itself will have been signed by the user).
             - Set `constants.isConstructorRecursion := true` - This public input will percolate to, and be checked by. the Contract Deployment Kernel Circuit which calls this constructor. This check is required to prevent a person from circumventing the ECDSA signature check by simply setting `isConstructor = true` when making a private call. If this aggregated kernel snark reaches the rollup circuit without this flag being reset to `false` by the Contract Deployment Kernel Circuit (to say "yes, this kernel was indeed a constructor for a Contract Deployment Kernel Circuit"), then the entire tx will be rejected by the rollup circuit.
         - Else:
             - Set `constants.isConstructorRecursion := false`

+            - Verify the ECDSA `signature`, with `message := privateCallHash` and `signer := privateCall.callContext.msgSender`.
             - Validate the `callContext`. Usually the correctness of a callContext is checked between the `privateCall` and all the new calls it makes (see later in this logic). That means for this 'Base case', those checks haven't been done for this `privateCall` (since there was no prior iteration of this kernel circuit to make those checks).
                 - If `privateCall.isDelegateCall == true || privateCall.isStaticCall == true`:
                     - Revert - a user cannot make a delegateCall or staticCall.

@@ -16,7 +16,7 @@ All private contract circuits have a fixed number of public inputs. Most of thes
 | *`customPublicOutputs` | Up to 32 circuit-specific values _returned by_ circuit. All of these inputs will be 'swallowed' by the private kernel snark. Hence any private outputs can safely be put here, which enables private circuits to call other private circuits, and pass private data to them. |
 | `emittedPublicInputs` | Public inputs which will be revealed to the 'public world' (L1 or L2). E.g. allowing certain inputs to be more-easily extracted by the RollupProcessor contract (rather than having to unpack this vast ABI object of inputs, which would cost too much hash-wise). An example of its usefulness is passing a value from L1 to L2 when doing an L1->L2 tx (see 'deposit' example in the other doc). TODO: consider whether this could be a single value, for simplicity. It could be a hash of data if more values need to be exposed. If so, we'll rename to `emittedPublicInputsHash`. |
 | *`executedCallback: {` | Populated if this circuit is a callback, so that the purported L1 Result to which this circuit is responding can be validated against the l1ResultsTree. |
-| `- l1ResultHash`, | If this function is a callback function, following some L1 call, then it needs to expose the `l1ResultHash` to ensure the callback is actually using data emitted by L1. The preimage of the `l1ResultHash` will need to be passed in as private inputs to the circuit. Note: the `l1ResultHash` MUST be computed with a sha256 hash, because that's what the RollupProcessor will have used. This is unfortunate, as it forces apps to adhere to a specific calculation within their circuits. DISAGREE NOW - we don't need to calcualte this within the app circuit: we can just hash the custom_public_inputs and compare that hash against the L1ResultHash. |

-# Questions
-
-A list of random thoughts and questions that haven't been fully considered yet.
-
-This isn't a comprehensive list of questions - there are loads dotted around these pages.
-
-- Where to develop the code?
-  - Will need to make significant edits to Falafel.
-  - Aztec Connect circuits aren't needed.
-- How should I proceeed?
-  - I could plan out lots of distinct tasks.
-  - Roadmap:
-    - Releases with milestones of functionality?
-    - One final big release at the end?
-    - E.g. Charlie suggested ignoring Public circuit functionality altogether initially.
-  - I can start writing kernel circuits, rollup circuits, making changes to falafel, writing smart contracts.
-- Components:
-  - Smart contract language: Noir?
-  - Testing framework: also Noir?
-  - Rollup provider full node: Falafel?
-    - Receives tx requests
-    - Creates rollups
-      - Coordinates delegation of proofs (future enhancement)
-    - Tracks the entire L2 state
-  - Rollup delegate node: Falafel in  different 'mode'.
-    - Can be given / takes instructions to generate proofs for the rollup.
-    - Incentivisation mechanism needed? I think we can avoid this.
-  - User node: Also Falafel in a different 'mode', or separate?
-    - For generating client-side proofs
-    - Submitting proofs to the Rollup Provider pool
-    - For keeping minimal user state witnesses and querying stuff.
-  - User node: non-browser version?
-  - web3.js/ethers.js pacakge to convert JS tx requests into the Aztec 3 ABI format.
-- Noir - how 'high-level' should it be?
-  - One extreme: it 'abstracts away' all of Aztec 3's architecture from the developer.
-    - Problem: one API for developer, and another ABI for the underlying circuit.
-      - Either need Noir plugged into a DB (but I'd prefer it to be stateless)
-      - Or need an ethers.js program to take a JS tx, query the falafel DB, then send an ABI-style tx to Noir.
-    - If we make architecture changes to the Public Inputs ABIs (which we will when optimising), Noir would need corresponding changes.
-  - Other extreme: a developer needs to write, in detail, circuits which conform to the Aztec 3 spec.
-- Once the HONK backend is ready, will we be able to simply 'swap' our kernel circuits' backend from PLONK to HONK?
-- Ask about callbacks:
-  - One-time-use callbacks (my preference) vs callback behaviour designed by each dev.
-  - Dedicated, decorated callback functions vs general functions that don't even _know_ they're a callback.
-    - If decorated as callback, the function can contain L1 result reconciliation logic.
-    - If general functions, then the L1 result reconciliation must happen in the kernel circuit / base rollup circuit.
-- Meh: Take a look at an [alternative suggestion for callbacks](./architecture/contracts/l1-calls.md#alternative-approach-to-callbacks), and decide which is best.
-- Decentralisation Roadmap:
-  - Rollup provider selection process?
-    - Aztec Token tokenomics.
-  - Tx pool - p2p messaging layer? Or direct messaging (if the Rollup Provider is the same for a period of time)?
-- Revisit discussion on fees and attributing L2 fees payments to provers based on their proving work.
-- Use ETH as L2 gas payment currency, or allow any general function to be labelled as a 'fee paying' currency?
-  - If we have specific gas costs relating to SLOAD / GEN_PROOF, then these will need to be paid in ETH surely?
-- Ask about dynamic arrays and what the limitations are in UltraPlonk.
-  - Pushing to all of these callStacks is going to expensive (constraint-wise), especially if we want to tightly pack pushes. Lots of O(n^2) searching for correct positions in arrays.
-  - Unless we can do some clever dynamic array stuff with ultraplonk / honk?
-- Do we need to emit all events to a special log that can be parsed? Like an L2 version of Ethereum's logs?
-  - E.g. how can app-specific javascript code 'react' to an event emitted by an L2 function?
-  - How does Ethereum do it?

 The following describes how many public inputs each public/private circuit will have and how they will be interpreted.
 
 
-## Private Circuit ABI
+## `CallContext`
+
+Much of the CallContext comes from the [`TxContext`](../contracts/transactions.md#txcontext) over which the user signs.
+
+| Value | Description |
+| --- | --- |
+| `txOrigin`: `aztecAddress` | The user who signed over this tx. We'll need this when making nested function calls, because private keys for nested circuits might need to be grabbed from the Private Client's DB based on this address -- not from the calling contract's address (since a contract cannot have private keys). |
+| `msgSender`: `aztecAddress` | - If doing a `call` or `staticCall`: Either the user address or the address of the contract that created the call. (Can be set to `0` for private -> public calls) 
 - If doing a `delegateCall`: the address of the calling contract's own `callContext.msgSender` (since delegate calls can be chained). |
+| `storageContractAddress`: [`ContractAddress`](../contracts/transactions.md#contractaddress) | - If doing a `call` or `staticCall`: the address of the contract being called. 
 - If doing a `delegateCall`: the address of the calling contract's own `callContext.storageContractAddress` (since delegate calls can be chained).
+| `isDelegateCall` : `Bool` | Used by the kernel snark to validate that the `callContext` of newly-pushed `callStackItems` is consistent with the contract making the call. |
+| `isStaticCall` : `Bool` | Informs the kernel snark that it MUST fail if the function being called modifies state. 

 A state modification includes: creating a new contract; emitting events; writing to trees; making a 'call' to another contract. :question: Not sure why 'delegatecall' is not included as a potentially state-modifying tx in ethereum specs? 

 Note: static calls to private circuits might not make sense. 'Reads' from the privateDataTree require a write of equal value, but the kernel snark cannot 'see' what has been written (it's a private tx), and so cannot validate that a state change didn't take place. So there would be no output commitments or nullifiers for a private static call. But a private call's only use is (I think :question:) to read/modify private state. So I'm thinking a staticCall to a private circuit doesn't make sense. |
+| `reference_block_num`: Field | The rollup number which should be used if referring to any historic tree values. Useful if the proof needs to use a particular tree state snapshot of a particular historic rollup. |
+
+## `StateTransition`
+
+Describes a single `publicDataTree` read+write operation.
+
+A 'state transition' is expressed as:
+- `[storageSlot, old_value, new_value]`.
+
+:heavy_exclamation_mark: For state transitions, the caller might not know the `old_value` nor the `new_value` when they make the call (i.e. when they add the call to their callStack), since the value will depend on the current state of the publicDataTree. (Imagine if the storage slot represented total liquidity in some pool which changes frequently. Then the old and new values are only known at the time the rollup processor actually organises the ordering of txs in their block).
+
+Conclusion: the `publicInputs` data which is included in a [`PublicCallStackItem`](../contracts/transactions.md#publiccallstackitem) cannot include the `old_value` nor `new_value` inputs. Therefore, the `stateTransitions` that are populated by a user when generating the `PublicCallStackItemHash` will have `0`-valued placeholders for `old_value` and `new_value`. Pure reads can be emulated by setting a new write value to equal the read value. However, for this tree, we could halve the amount of hashing for pure reads by having a separate `reads` set of inputs. A read can be done without a write for this tree (see next field).
+
+| Value | Description |
+| --- | --- |
+| `storageSlot`: `Field` | The slot that the circuit wants to modify. |
+| `oldValue`: `Field` | Old value is checked by the kernel circuit to be correct. |
+| `newValue`: `Field` | New value inserted by the kernel circuit. |
+
+## `StateRead`
+
+For efficiency (vs a StateTransition), we can read public state without writing. As explained above, the `current_value` won't necessarily be known by the user when they generate the call, so `current_value` is replaced with `0` when the `PublicCallStackItem` is generated for calls to a public function.
+
+| Value | Description |
+| --- | --- |
+| `storageSlot`: `Field` | The slot that the circuit wants to modify. |
+| `currentValue`: `Field` | Current value is checked by the kernel circuit to be correct. |
+
+# Private Circuit ABI
 
 All private contract circuits have a fixed number of public inputs. Most of these public inputs will eventually be swallowed by the [private kernel circuit](../kernel-circuits/private-kernel.md). Under some circumstances, some public inputs will be optionally revealed to the 'public world, depending on the various booleans in this table.
 
 > Note: some of these inputs might be packed into 1 field for efficiencies in the implementation, but for ease of understanding they're kept separate here.
 
+## `PrivateCircuitPublicInputs`
 
 | Data type | Description |
 | -------- | -------- |
-| *`customPublicInputs` | Up to 32 circuit-specific inputs passed into this circuit. All of these inputs will be 'swallowed' by the private kernel snark. Hence any private args can safely be put here, which enables private circuits to call other private circuits, and pass private data to them. To reveal data to the 'public world', either call a public function or emit an event. |
-| *`customPublicOutputs` | Up to 32 circuit-specific values _returned by_ circuit. All of these inputs will be 'swallowed' by the private kernel snark. Hence any private outputs can safely be put here, which enables private circuits to call other private circuits, and pass private data to them. |
-| `emittedPublicInputs` | Public inputs which will be revealed to the 'public world' (L1 or L2). E.g. allowing certain inputs to be more-easily extracted by the RollupProcessor contract (rather than having to unpack this vast ABI object of inputs, which would cost too much hash-wise). An example of its usefulness is passing a value from L1 to L2 when doing an L1->L2 tx (see 'deposit' example in the other doc). TODO: consider whether this could be a single value, for simplicity. It could be a hash of data if more values need to be exposed. If so, we'll rename to `emittedPublicInputsHash`. |
-| *`executedCallback: {` | Populated if this circuit is a callback, so that the purported L1 Result to which this circuit is responding can be validated against the l1ResultsTree. |
-| `- l1ResultHash`, | If this function is a callback function, following some L1 call, then it needs to expose the `l1ResultHash` to ensure the callback is actually using data emitted by L1. The preimage of the `l1ResultHash` will need to be passed in as private inputs to the circuit. Note: the `l1ResultHash` MUST be computed with a sha256 hash, because that's what the RollupProcessor will have used. This is unfortunate, as it forces apps to adhere to a specific calculation within their circuits. DISAGREE NOW - we don't need to calcualte this within the app circuit: we can just hash the custom_inputs and compare that hash against the L1ResultHash. |
-| `- l1ResultsTreeLeafIndex`, | Communicates to the rollup provider the correct leaf to prove membership against in the l1ResultsTree. Only if we don't want to hide the callback will the rollup provider perform the membership check (within the Base Rollup Circuit). Otherwise it'll be performed in the Private Kernel Circuit. |
-| `}`|
-| `outputCommitments` | output notes to be added into the `privateDataTree` (up to 16) | 
-| `inputNullifiers` | input nullifiers to be added into the `nullifierTree` (up to 16) |
-| `privateCallStack` | additional private calls created by this transaction (up to 16) |
-| `publicCallStack` | additional public calls created by this transaction (up to 16) |
-| `contractDeploymentCallStack` | additional calls which  _deploy contracts_, created by this transaction (up to 1?) |
-| `partialL1CallStack` | additional calls to L1 created by this transaction (up to 16). "Partial" because the kernel circuit will add the correct portal contract address to 'complete' the call into a proper L1 CallStack Item. See [here](../contracts/l1-calls.md). |
-| 
callbackStack = [{
  callbackPublicKey, 
  successCallbackCallHash, 
  failureCallbackCallHash, 
  successResultArgMapAcc, 
},...]
 | An element in the array for each new L1 call on the `l1CallStack`. See [more](../contracts/l1-calls.md). We need to expose all of this data so that the kernel snark ensures the callback is a function of the same contract which made the call. |
-| *`oldPrivateDataTreeRoot` | used to query the `privateDataTree` |
-| Booleans: | |
-| *`bool isFeePayment` | Notifies the kernel circuit that the following public inputs of this private circuit MUST be revealed to the public kernel circuit:
  • `functionSignature` - so that the rollup provider can see how they're to be paid 
  • `emittedPublicInputs` - so that the rollup provider can validate the amount they'll be paid (they'll need to be provided with the underlying public inputs separately, to validate the hash).
 |
-| *`bool payFeeFromL1`| Provides a way of paying for private L2 function execution from L1 (the RollupProcessor.sol could provide the interface for ETH or ERC20... but we could generalise this by somehow pointing to a particular 'other' payment L1 contract state?). "Submit on-chain the callHash and state a fee (in L1 currency) for the L2 tx, and then when the L2 tx is executed, the rollup provider may redeem the previously-published fee". 

  Notifies the kernel circuit that the following public inputs of this private circuit MUST be revealed to the public kernel circuit:
  • `callHash` - no other data is needed (in order to allow the user to keep the function they've actually executed private).
 |
-| *`bool payFeeFromPublicL2`| Provides a way of paying for private L2 function execution from a public L2 circuit. This input being `true` will cause the rollup provider to look for an `isFeePayment` tx in the _public_ callStack. |
-| *`bool calledFromL1` | If the L1 contract wants to call a specific L2 circuit, then the function signature needs to be revealed on-chain so that it can be checked that the correct, intended function was executed. 

 Notifies the private kernel circuit that an L1 contract wants to call this specific private L2 circuit, and so the following MUST be revealed to the public kernel circuit: 
  • `functionSignature` - needed so the L1 contract can confirm the intended function was executed on L2. Although a callHash contains the functionSignature, the L1 contract wouldn't (cheaply) be able to unpack the callHash. So we expose the function signature as well to keep costs down. Although this leaks the function which was called, there's no way around that; this is an L1 -> L2 call after all.
  • `callHash` - used as a 'lookup' key. The RollupProcessor will store this `callHash`, and await an L2 tx with this `callHash` before triggering a callback to the L1 contract which made this L1 -> L2 call in the first place.
  • `emittedPublicInputs` - needed so that a set of values can be emitted by an L2 function and exposed to L1. It would be too expensive to unpack the callHash and extract all of the custom public inputs of a circuit. This is much cheaper, and is very similar to how the EVM exposes only a few values (via event emissions) to JavaScript (for example).
 

 We need this convoluted process, because the RollupProcessor has to be _sure_ an L1 fee has been set-aside for them, before they add any corresponding L2 states. |
-| Global vars: | |
-| *`minTimestamp` | a timestamp value that must be exceeded when the block containing this txn is mined |
+| `callContext`: [`CallContext`](#callcontext) | Information about what this function used as its call context, so that the kernel circuit may validate that the correct context was indeed used. |
+| `args`: `Array[Field]` | Arguments passed into this circuit. All of these inputs will be 'swallowed' by the private kernel snark. Hence any private args can safely be put here, which enables private circuits to call other private circuits, and pass private data to them. To reveal data to the 'public world', either call a public function or emit an event. |
+| `returnValues`: `Array[Field]` | Values _returned by_ circuit. All of these outputs will be 'swallowed' by the private kernel snark. Hence any private outputs can safely be put here, which enables private circuits to call other private circuits, and receive return data from them. |
+| `emittedEvents`: `Array[Field]` | Public inputs which will be revealed to the 'public world' (L1 or L2). E.g. allowing certain inputs to be more-easily extracted by the RollupProcessor contract (rather than having to unpack this vast ABI object of inputs, which would cost too much hash-wise). An example of its usefulness is passing a value from L1 to L2 when doing an L1->L2 tx. |
+| `newCommitments`: `Array[Field]` | new commitments to be added into the `privateDataTree` | 
+| `newNullifiers`: `Array[Field]` | new nullifiers to be added into the `nullifierTree` |
+| `privateCallStack`: `Array[Field]` | Additional private calls made by this function. The `Field` is a hash of a [`PrivateCallStackItem`](../contracts/transactions.md#privatecallstackitem). |
+| `publicCallStack`: `Array[Field]` | Additional public calls created by this transaction. The `Field` is a hash of a [`PublicCallStackItem`](../contracts/transactions.md#publiccallstackitem). |
+| `contractDeploymentCallStack`: `Array[Field]` | Additional calls which  _deploy contracts_, created by this transaction. The `Field` is a hash of a [`ContractDeploymentCallStackItem`](../contracts/transactions.md#contractdeploymentcallstackitem). |
+| `partialL1CallStack`: [`Array[PartialL1CallStackItem]`](../contracts/transactions.md#l1callstackitem) | Additional calls to L1 created by this transaction. "Partial" because the kernel circuit will add the correct portal contract address to 'complete' the call into a proper L1 CallStack Item. See [here](../contracts/l1-calls.md). We need to expose all of this data (rather than hashing it to a `Field`), because the kernel snark needs to pass this data to L1, and unlike the earlier callstacks, we'll never have another opportunity to pass this 'unpacked' data into any other kernel snark. |

 >- What _can_ be done is a defi-bridge-like chain of events: a private circuit generates a partial commitment, and then the public circuit completes that partial commitment with some public state and adds it to the privateDataTree. But that doesn't require explicit public -> private calls.
 
 
-> **Aside:** we don't think we need chained transactions for Aztec 3. Recall: chained transactions give the ability to nullify a newly-created commitment _within_ the same rollup; before it's been added to the dataTree. This isn't needed. For a user to chain state to themselves, they can just create a callstack. The notion of chaining _between_ users is really complicated, and possibly not useful in practice. In particular, chaining doesn't play well with the idea of binary rollup trees, since the number of 'chaining' comparisons would blow up exponentially with the level of the rollup tree (meaning we'd need to build differently-sized rollup circuits per level). Recall: linked transactions give the ability to 'await' the inclusion of 'other' transactions in the rollup, before processing 'this' transaction. Unsure whether that's needed.

-## Public Circuit ABI
+# Public Circuit ABI
 
 The public contract ABI is similar to the private one.
 
 Whilst the _user_ provides all the values specified by this Public Circuit ABI, it's the _rollup provider_ who actually generates public contract proofs. This is because the rollup provider is the only party with perfect knowledge of the current Merkle roots, meaning only they can access/update the public data tree, as well as know the exact block number etc.

+**NOTE** This section is out of date. Public function execution might differ drastically from this old draft. Not worth even reading this section anymore.
 
 | Data Type | Description |
 | -------- | -------- |
-| `customPublicInputs` | Up to 32 circuit-specific inputs passed into this circuit. All of these inputs will be 'swallowed' by the public kernel circuit. |
-| `customOutputs` | Up to 32 variables 'returned' by calling this function. All of these inputs will be 'swallowed' by the public kernel circuit. Note, unlike the private circuit ABI (which doesn't have a `customOutputs` field like this), it's possible for public circuit execution to output values which were derived from the current state of the public data tree - such values cannot have been known by the caller of the function, and hence can truly be considered 'outputs'. Note, since the caller won't necessarily known what these outputs will be when they make the call, this entire `customOutputs` field is omitted from the `callStackItemHash` when the user makes the call. |
-| `emittedPublicInputs` | Public inputs which may be revealed to L1. E.g. allowing certain inputs to be more-easily extracted by the RollupProcessor contract (rather than having to unpack this vast ABI object of inputs, which would cost too much hash-wise). An example of its usefulness is passing a value from L1 to L2 when doing an L1->L2 tx (see 'deposit' example in the other doc). |
-| `emittedOutputs` | As above, except these values won't necessarily be known when the call is made; only when the rollup provider is generating the witness for this function's execution. Note, since the caller won't necessarily known what these outputs will be when they make the call, this entire `customOutputs` field is omitted from the `callStackItemHash` when the user makes the call. |
-| `executedCallback: {` | Populated if this circuit is a callback, so that the purported L1 Result to which this circuit is responding can be validated against the l1ResultsTree. |
-| `- l1ResultHash`, | If this function is a callback function, following some L1 call, then it needs to expose the `l1ResultHash` to ensure the callback is actually using data emitted by L1. The preimage of the `l1ResultHash` will need to be passed in as private inputs to the circuit. Note: the `l1ResultHash` MUST be computed with a sha256 hash, because that's what the RollupProcessor will have used. This is unfortunate, as it forces apps to adhere to a specific calculation within their circuits. |
-| `- l1ResultsTreeLeafIndex`, | Communicates to the rollup provider the correct leaf to prove membership against in the l1ResultsTree. Only if we don't want to hide the callback will the rollup provider perform the membership check (within the Base Rollup Circuit). Otherwise it'll be performed in the Private Kernel Circuit. |
-| `}`|
-| 256 `stateTransitions` | Describes up to 256 `publicDataTree` read+write operations. 
 A 'state transition' is expressed as: 
 `[storageSlot, old_value, new_value]`. 
:heavy_exclamation_mark: For state transitions, the caller might not know the `old_value` nor the `new_value` when they make the call (i.e. when they add the call to their callStack), since the value will depend on the current state of the publicDataTree. (Imagine if the storage slot represented total liquidity in some pool which changes frequently. Then the old and new values are only known at the time the rollup processor actually organises the ordering of txs in their block). Conclusion: the `publicInputsHash` which is included in a public call's `callStackItemHash` cannot include the `old_value` nor `new_value` inputs. 

 Therefore, the `stateTransitions` that are populated by a user and hashed when generating the `callStackItemHash` will have `0`-valued placeholders for `old_value` and `new_value`. 

 Pure reads can be emulated by setting a new write value to equal the read value. However, for this tree, we could halve the amount of hashing for pure reads by having a separate `reads` set of inputs. A read can be done without a write for this tree (see next field). |
-| `stateReads` | Pure reads. Each 'read' request is simply the `[storageSlot, current_value]`. As explained above, the `current_value` won't necessarily be known by the user when they generate the call, so `current_value` is replaced with `0` when the `callStackItemHash` is generated for calls to a public function. |
-| `publicCallStack` | additional public calls to be made by this transaction (up to 16) |
-| `contractDeploymentCallStack` | additional calls which  _deploy contracts_, created by this transaction (up to 1?) |
-| `partialL1CallStack` | Additional L1 calls to be made by this transaction (up to 16). "Partial" because the kernel circuit will add the correct portal contract address to 'complete' the call into a proper L1 CallStack Item. See [here](../contracts/l1-calls.md). |
-| 
callbackStack = [{
  callbackPublicKey, 
  successCallbackCallHash, 
  failureCallbackCallHash, 
  successResultArgMapAcc, 
},...]
 | An element in the array for each new L1 call on the `partialL1CallStack`. See [more](../contracts/l1-calls.md). We need to expose all of this data so that the kernel snark ensures the callback is a function of the same contract which made the call. |
-| `oldPrivateDataTreeRoot` | used to query the `privateDataTree` |
-| `proverAddress` | Who is going to be generating the proof for this circuit (any value can be injected here by the prover). :question: IS THIS ALLOWED HERE? It can be allowed here as long as Noir abstracts its existence away from the circuit developer. |
-| Booleans: | |
-| `bool isFeePayment` | Notifies the rollup provider that this function pays them their fee. The rollup provider will need a way to interpret the many ways it can be paid. :question: Perhaps a fee payment ABI is required for the structure of the `emittedPublicInputs`, for example? |
-| `bool payFeeFromL1`| Provides a way of paying for L2 function execution from L1 (the RollupProcessor.sol could provide the interface for ETH or ERC20... but we could generalise this by somehow pointing to a particular 'other' payment L1 contract state?). "Submit on-chain the callHash and state a fee (in L1 currency) for the L2 tx, and then when the L2 tx is executed, the rollup provider may redeem the previously-published fee". 

  Notifies the kernel circuit that the following public inputs of this public circuit MUST also be revealed by the public kernel circuit:
  • `callHash`
 |
-| `bool calledFromL1` | If the L1 contract wants to call a specific L2 circuit, then the function signature needs to be revealed on-chain so that it can be checked that the correct, intended function was executed. 

 Notifies the public kernel circuit that an L1 contract wants to call this specific public L2 circuit, and so the following MUST be revealed by the public kernel circuit: 
  • `functionSignature`
  • `callHash`
  • `emittedPublicInputs` (possibly)


 We need this convoluted process, because the RollupProcessor has to be _sure_ an L1 fee has been set-aside for them, before they add any corresponding L2 states. |

-### publicInputsHash
 
-As explained briefly in the table above, for calls to a public circuit, certain inputs are _not_ known when the user makes the call (since their values might depend on the state of the public data tree at the time of proof generation (rather than at the time of making the call)). Therefore, the `publicInputsHash` for public calls is defined as the hash of the above ABI data, _except_ for the following modifications to the preimage:
-- `customOutputs` fields are completely omitted from the preimage.
-- `emittedOutputs` fields are completely omitted from the preimage.
-- Each state transition is truncated to be `storageSlot` (instead of `[storageSlot, old_value, new_value]`).
-- Each state read is truncated to be `storageSlot` (instead of `[storageSlot, current_value]`).
+**Note**: For calls to a public circuit, certain inputs are _not_ known when the user makes the call (since their values might depend on the state of the public data tree at the time of proof generation (rather than at the time of making the call)). Therefore, the `publicInputs` provided when making public calls (i.e. when creating a [`PublicCallStackItem`](../contracts/transactions.md#publiccallstackitem)) sets-to-0 some of the above data.
+- `returnValues`
+- `emittedEvents`
+- `stateTransitions`' old and new values.
+- `stateReads`' current values.
+- All call stacks (as the calls could be made based on some dynamic state read of some address, for example)

-## Contract Deployment ABI
+# Contract Deployment ABI
 
 Recall:
 
 Contracts can be deployed to Aztec's Layer 2. A contract comprises:
 - a set of functions, each encapsulated by a `(vk, proving_key, circuit)` tuple, with the hash of the `vk` being a succinct and unique representation of each function.
 - state variables, split across these trees:
-    - `publicDataTree`
+    - `publicDataTree` (maybe also a const public data tree)
     - `privateDataTree`
 
 A contract deployment ABI, therefore, needs to communicate this information to the rollup provider.
 
-This is the ABI for the public inputs that must be specified when making a call to deploy a new contract. These public inputs will then be hashed into a `publicInputsHash` which will form part of the [`callStackItemHash`](../contracts/transactions.md#callstackitemhash) which will get added to the `contractDeploymentCallStack`.
+This is the ABI for the public inputs that must be specified when making a call to deploy a new contract. These public inputs will form part of the [`ContractDeploymentCallStackItem`](../contracts/transactions.md#contractdeploymentcallstackitem) which will get added to the `contractDeploymentCallStack`.
 
 **Important note**: Unlike for the above Public Input ABIs for private circuits and public circuits, we don't actually have a 'contract deployment' _circuit_. These public inputs are simply defined so that a callStackItem can be created. These public inputs (and others) are then fed directly into a [Contract Deployment _Kernel_ Circuit](../kernel-circuits/contract-deployment-kernel.md).
 
 
 TODO: we might be able to remove some of these public inputs and provide them privately instead; but such optimisations can happen _much_ later in this project.
 
+PROBLEM: we might wish to _prove_ that a set of ACIR++ opcodes compiles to a particular vkHash. This would be very complex to do inside a circuit, but might be essential.

-# Transactions (Calls)
+# Transactions
 
-A transaction begins as a call to a single function[^1]. A function can be uniquely identified (across all contracts) by its [`functionSignature`](#function-signature). A 'call' to a function is expressed through a [`callStackItem`](#call-stacks). During the execution of a transaction, the initial function might make calls to other functions, so callstacks are required. Call stack items are verified recursively. The final kernel snark that is produced by the recursion represents the entire transaction.
+A transaction always comes from a user account, and must be signed by that user's aztec private key. A transaction represents a call to some function of some contract, passing some parameters, and specifying some fee.
+
+
+
 
 Contracts can be deployed with a special type of call (a contractDeploymentCall).
 
 [^1]: Most transactions will likely begin with _two_ callstack items: one for the actual call, and one to pay the rollup provider a fee (by invoking some payment circuit). [Fee payments](../fees/fees.md) still need to be spec'd out.
-## Function signature
 
-A private function call is uniquely defined by a 64-bit integer, which we'll call a `functionSignature`:

For calls which deploy a contract, this is `0` (context will be understood from the fact this will be popped of a contractDeploymentCallStack). 
For calls to private constructors, this is not known when generating the private kernel proof which verifies the private constructor (as the contract won't yet have been assigned an address), so is `0` (in combination with `functionSignature.isConstructor == true`). |
+| `functionSignature`: [`FunctionSignature`](#functionsignature) | An identifier for the function being called. |
+| `args`: `Array[Field]` | Arguments being passed into the function by this tx. |
+| `nonce`: `Field` | Useful for overriding a tx which has already been sent to the pool. Note: for private function calls, this _must not_ be incremented sequentially, but should be random-looking. 
`0` if this is a fee-paying tx to accompany a 'proper' tx. |
+| `txContext`: [`TxContext`](#txcontext) | Miscellaneous data relating to this tx, which might be useful for all subsequent nested function calls, and kernel circuits of this tx. |
+| `chainId`: `Field` | Needed to prevent replay attacks on other rollups (e.g. testnet / devnet). 
`0` if this is a fee-paying tx to accompany a 'proper' tx. |

 For calls which deploy a contract, this is `0` (context will be understood from the fact this will be popped of a contractDeploymentCallStack). 
For calls to private constructors, this is not known when generating the private kernel proof which verifies the private constructor, so is `0` (in combination with `isConstructor`). |
-| 32-60 (29-bits) | `vkIndex` - the position of the vk (i.e. its leaf index) in this contract's `vkTree` (this defines the function being called) |
-| 61 (1-bit) | `isPrivate` - A bit describing if this function is public or private. 

:question: Is this needed? Perhaps the differences in private/public ABIs is sufficient to cause a circuit to fail if passed the wrong proof type? Or, maybe the vk tree could be arranged in a way which clearly separates public/private vks. |
-| 62 (1-bit) | `isConstructor` - If a function is a constructor, it's going to be called by the Contract Deployment Kernel circuit. This flag notifies the kernel circuit that this private circuit is being executed as a constructor for the deployment of a new contract, and so the following public inputs of this private circuit MUST be revealed to the public kernel circuit (so that the Contract Deployment kernel circuit may validate them): 
  • `callStackItemHash` - so that the Contract Deployment kernel circuit (and interested parties) can be convinced that the constructor was run with the correct set of inputs (this might need to exposed all the way to L1)
  • `vkHash` - so that the Contract Deplyment constructor can validate that the correct function was executed. (Notice, we don't use a conventional `functionSignature` because we won't be adding constructor vkHashes to the vkTree). Notice, by design, this doesn't reveal any details to observers about the nature of the executed function. We might want to optionally allow the underlying vk to be broadcast (and hence we might need to expose this vkHash all the way to L1).
  • `emittedPublicInputs` - to pass particular inputs to L1.

Special note: this `isConstructor` flag is not part of the private circuit's ABI (as it potentially could have been), because the checks in the contract deployment kernel circuit are much cheaper if it's accessible here. |

It is derived as the first 4 bytes of the hash of the abi encoding of the function, similar to Solidity. The reason we do this, is so that a vkIndex can be derived from a contract interface, regardless of the ordering of that interface's functions. |

-_Note_: the `contractTree` is append-only, so individual verification keys can't be 'replaced' for bug-fixes etc.; the entire contract (a `vkTree`) would need to be re-deployed to the next available slot in the `contractTree`. Such re-deployments, of course, would change the contract address.

 Notifies the private kernel circuit that an L1 contract wants to call this specific private L2 circuit, and so the following MUST be revealed to the public kernel circuit: 
  • `functionSignature` - needed so the L1 contract can confirm the intended function was executed on L2. Although a callHash contains the functionSignature, the L1 contract wouldn't (cheaply) be able to unpack the callHash. So we expose the function signature as well to keep costs down. Although this leaks the function which was called, there's no way around that; this is an L1 -> L2 call after all.
  • `callHash` - used as a 'lookup' key. The RollupProcessor will store this `callHash`, and await an L2 tx with this `callHash` before triggering a callback to the L1 contract which made this L1 -> L2 call in the first place.
  • `emittedPublicInputs` - needed so that a set of values can be emitted by an L2 function and exposed to L1. It would be too expensive to unpack the callHash and extract all of the custom public inputs of a circuit. This is much cheaper, and is very similar to how the EVM exposes only a few values (via event emissions) to JavaScript (for example).

 Note: static calls to private circuits might not make sense. 'Reads' from the privateDataTree require a write of equal value, but the kernel snark cannot 'see' what has been written (it's a private tx), and so cannot validate that a state change didn't take place. So there would be no output commitments or nullifiers for a private static call. But a private call's only use is (I think :question:) to read/modify private state.

 # Contract Deployment Kernel Circuit
 
+
+**NOTE: this section is out of date (naming and architecture), given recent conversations.**
+
+
 Notice, that this is a _kernel_ circuit. That's because this circuit will itself verify a private &or public kernel snark representing the new contract's 'constructors'. Unlike the other two (private & public) kernel snarks though, Contract Deployment Kernel Circuits can be called by users and/or functions, meaning they have a callStack of their own which can be pushed-to. The Contract Deployment call stack will be processed at the very end of the kernel chain; after the private and public kernels have been executed.
 
 You'll notice that the private/public inputs for this kernel circuit are a superset of the inputs of both the private & public kernel circuits. That's because contract deployments are processed at the very end of a tx, so all other data needs to 'pass through' this circuit.

-                      - Extract the underlying results `l1SuccessResultValues = privateCall.privatelyExecutedCallback.l1SuccessResultValues;`
-                      - Reconcile the `privateCall.privatelyExecutedCallback.callbackStackItem.successResultArgMapAcc` against `positionData` (messy computation if using turboplonk).
-                        - `positionData` is probably binary decompositions, so range checks aren't needed. Multiply all the stuff together with the primes (details omitted, since this solution is a stop-gap). No need to prevent duplicate positions here: the app circuit must do that when it makes the initial call.
-                        - Compare the resulting value against `successResultArgMapAcc`.
-                        - Then, for turbo: sum each of the `positionData` 'columns' to get the `position` as a value. For each `position` loop through the `privateCall.publicInputs.customPublicInputs` until reaching the index `i` of the `position`, and then `require(customPublicInputs[i] == l1SuccessResultValue[i]`.

-                    - `constants.oldTreeRoots.l1ResultsTree`
-                - Validate the `callbackPrivateKey`:
-                    - `require(callbackPrivateKey * G = callbackPublicKey)` (for some fixed point `G`).
-                - Set `callbackNullifier := hash(callbackDatumHash, callbackPrivateKey)` to prevent this callback from being executed again.
-                - Set `isCallbackRecursion = false;` to hide that this is a callback, and to prevent callback logic being triggered later in the Base Rollup circuit.
-                - Ensure `constants.executedCallback` is zeroes.
-                - We don't include the whole `leafValue` in the preimage of the nullifier, to prevent a user maliciously calling the callback twice: once for 'success' and once for 'fail' (although that shouldn't be possible if the 'L1 results copier' circuit works correctly).

 The public circuit tracks its own call depth. If `start.publicCallCount == 0` , one of two conditions must be met:

 # Contract Deployment
 
 A contract is a collection of functions and state variables. Each 'function' is expressed as a circuit, and each circuit can be represented by its verification key. I.e. each verification key represents a callable function in the smart contract.

+     * @brief This is an important optimisation, to save on the number of emitted nullifiers.
+     *
+     * A nullifier is ideal to serve as a nonce for a new note commitment, because its uniqueness is enforced by the
+     * Rollup circuit. But we won't know how many non-dummy nullifiers we have at our disposal (to inject into
+     * commitments) until the end of the function.
+     *
+     * Or to put it another way, at the time we want to create a new commitment (during a function's execution), we
+     * would need a nonce. We could certainly query the `exec_ctx` for any nullifiers which have already been created
+     * earlier in this function's execution, and we could use one of those. But there might not-yet have been any
+     * nullifiers created within the function. Now, at that point, we _could_ generate a dummy nullifier and use that as
+     * a nonce. But that uses up a precious slot in the circuit's nullifiers array (part of the circuit's public inputs
+     * abi). And it might be the case that later in the function, a load of non-dummy nullifiers get created. So as an
+     * optimisation, it would be better if we could use _those_ nullifiers, so as to minimise dummy values in the
+     * circuit's public inputs.
+     *
+     * And so, we provide the option here of deferring the injection of nonces into note_preimages (and hence deferring
+     * the computation of each new note commitment) until the very end of the function's execution, when we know how
+     * many non-dummy nullifiers we have to play with. If we find this circuit is creating more new commitments than new
+     * nullifiers, we can generate some dummy nullifiers at this stage to make up the difference.
+     *
+     * Note: Using a nullifier as a nonce is a very common and widely-applicable pattern. So much so that it feels
+     * acceptable to have this function execute regardless of the underlying Note types being used by the circuit.
+     *
+     * Note: It's up to the implementer of a custom Note type to decide how a nonce is derived, via the `set_nonce()
+     * override` method dictated by the NoteInterface.
+     *
+     * Note: Not all custom Note types will need a nonce of this kind in their NotePreimage. But they can simply
+     * implement an empty body in the `set_nonce() override`.

     - Public inputs
-    - Commitment/nullifier creation (recommendations)
+    - Syntax for State Variables & UTXOs
     - Function calls
-    - Everything from the 'Noir Examples' section of the Aztec3 book.
 - To help illustrate ideas to the Noir team

-This is some complex code, which attempts to abstract-away stuff to do with creating commitments, nullifiers, and Aztec3 public input ABIs. All that, so that test app circuits can be mocked-up without too much faff. Some explanation is needed:

+ * non-nullified UTXO in the tree at any time.  Notice the `get` and `insert` methods for this StateVar, which interact
+ * with the UTXO tree opcodes.
+ *
+ * @tparam Note - A UTXO state variable always acts on notes and note preimages. We allow for custom Note types to be
+ * designed. The Note type must implement the NoteInterface. TODO: maybe explicitly have this class act on the
+ * NoteInterface type, rather than a template type.

If this aggregated kernel snark reaches the rollup circuit without this flag being reset to `false` by the Contract Deployment Kernel Circuit (to say "yes, this kernel was indeed a constructor for a Contract Deployment Kernel Circuit"), then the entire tx will be rejected by the rollup circuit.

+# https://support.atlassian.com/bitbucket-cloud/docs/yaml-anchors/

+# Two primary anchors are checkout and setup_env, called as the first step of almost all jobs:
+# - checkout: A custom checkout step to reduce the amount of data downloaded to improve speed.
+# - setup_env: Sets up the common environment used by all build steps.
+#
+# Two CCI executors are used:
+# - docker (small): Used only to launch external EC2 instances for big workloads. It's the cheapest option.
+# - machine (large): Used for building in CCI itself. 4cpus, 15GB has the optimal power/cost ratio.
+#
+# The docker executor uses a custom image build in `build_image`. It's specifically streamlined for fast download
+# with just enough tools to execute the build system, and launch EC2 instances etc.
+#
+# There are some `join` steps that are just noops. They are just used to produce cleaner graph rendering in CCI.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

             - Set `constants.recursionContext.isConstructor := true` - This public input will percolate to -- and be checked by -- the Contract Deployment Kernel Circuit which calls this constructor. This check is required to prevent a person from circumventing the ECDSA signature check by simply setting `isConstructor = true` when making a private call. If this aggregated kernel snark reaches the rollup circuit without this flag being reset to `false` by the Contract Deployment Kernel Circuit (to say "yes, this kernel was indeed a constructor for a Contract Deployment Kernel Circuit"), then the entire tx will be rejected by the rollup circuit.

Subject: [PATCH 062/166] Linearised Prover Removed from BB (#31)

* Linearised prover removed from bb: so nomenclature has changed slightly.

`UnrolledProver` -> `Prover`

* Update submodule.

* More fixes.

Subject: [PATCH 063/166] Add cbind for hashing tx req along with test (#26)

* add cbind for hashing tx req

* cleanup txreq hash test

* debug info to hashing functions, rename cbind test for hashing

* debug

* change contract deployment data struct initialization (was getting garbage vals)

* c_bind working, cleanup

* doxygen comment for c_bind

* wasm sentence in doxygen comment for c_bind

* use NT::fr::serialize* instead of barretenberg::fr::serialize in kernel c_binds, use random inputs in tx req hash cbind test and just results against TxRequest.hash()

* rename/mv kernel c_bind tests to abis. Massively simplify hash_tx_req test

* cbind test comments

* better namespacing in cbind

* newline end of file

* remove unused namespace item

* cleanup test namespace, other minor cleanup

Subject: [PATCH 065/166] Update bb (to Phated's latest barretenberg master
 with large cmake infra update) (#37)

* update bb

* updating cmake infra to work with and use phated's latest barretenberg master

* add CMAKE_BBERG_PRESET cacheVariable that is used to set barretenberg's preset from this project. Fix gitignores

* fix bootstrap bug, fix externalproject for Ninja by adding BUILD_BYPRODUCTS

* use wasi-sdk in barretenberg submodule so that presets both point there. make sure WASM is set in cmake before doing

* fix wasi path in dockerfiles

* fix cpp path in scripts

* fix wasm dockerfiles and run_tests scripts for new cpp path and srs script paths

 As you might have guessed, 'functions' in Aztec's L2 will actually be circuits. Execution of a function will be performed by generating a zk-snark to prove its correct execution with a particular set of inputs. If a function makes a call to another function, a proof of each function's execution must be made _separately_. We need to then 'connect' those two proofs in a way which says "this function made a call to this other function, it passed-in these arguments and received these values in return". To do this, we make use of zk-snark recursion and a special 'callstack'. Notice that if each function must be executed as a standalone lego brick (a proof), then all input arguments and return values of every function call in a transaction must be known ahead of time, so that each proof can be generated separately. That'll be a fun engineering challenge!
 
-This is all expanded-on later in this book. When a function calls another function, we'll add details of the function _being called_ to a callstack[^1]: the contract address, the function signature, arguments, return values and a call context. We describe a 'Kernel Snark' which: pops the first proof off the callstack, verifies it, then adds new callstack items for any functions which the first function called. Kernel Snark execution proceeds recursively: the next Kernel Snark will verify the previous Kernel Snark's correctness, then will pop the next proof off the callstack, and add even more callstack items for any functions which this latest function has called. The 'stitching together' of arguments passed to functions and values returned from functions is implicit in this process, since each callstack item contains this information.

 This protocol describes 'private states' (a state whose value is known by a single user) and 'public states' (states whose values are visible to everyone). To edit these different states, we need two different kinds of circuits: private circuits and public circuits.

 # aztec3::circuits::abis
 
 Contains all ABIs for use by:
+
 - Test app circuits
 - Kernel circuits
 - Rollup circuits
 
-All ABIs are generalised by an `NCT` template parameter (meaning `NativeOrCircuitTypes`). `NCT` can be either `plonk::stdlib::types::NativeTypes` or `plonk::stdlib::types::CircuitTypes` for some `Composer`. The idea being, there's a single implementation of every struct/class for native and circuit types. NativeType structs can be switched to CircuitType with the `to_circuit_type()` method.

 ## Execution Logic
 
 We'll do a few things in the circuit:
+
 - Verify the two kernel snarks
 - Merge some arrays from both inputs
 - Check some tree stuff
 - Check the public inputs of both kernel snarks based on the ordering:
-    - `kernelSnarks[0]` happened first
-    - `kernelSnarks[1]` happened second
+  - `kernelSnarks[0]` happened first
+  - `kernelSnarks[1]` happened second
 
 So:

 - the base rollup circuit's `start` tree data must line up with the `initial...` tree data of `kernelSnarks[0]`.
 - the `end` tree data of `kernelSnarks[0]` must line up with the `initial...` tree data of `kernelSnarks[1]`.
 - the `end` tree data of `kernelSnarks[1]` must line up with the base rollup circuit's `end` tree data.

 Check the alignment of the start and end states of the two trees which were updated _within the kernel snarks_ (the publicDataTree and the contractTree). This ensures the kernel snarks didn't make any unexpected changes to those trees:

 If either of the kernel snarks was a callback execution, check that their purported L1 Result is correct (i.e. that it exists in the L1 results tree).
 We do this here, in the base rollup circuit rather than the public kernel circuit, because this only needs to be done at most once per tx, so it'd be wasteful to repeat this calc in every kernel recursion. Having said that, the _private_ kernel circuit does also offer this functionality, so that a user may hide which callback they're calling (and even the fact they're executing a callback at all).
 This logic MUST come before the 'nullifier insertion' logic, because we add a new nullifier to the set here.

Subject: [PATCH 078/166] Cbind for `compute_function_tree_root` (#65)

* cbind for compute_function_tree_root

* fix func tree root test for wasm

* compute_tree_root_native fix in bberg

* use NT random_element for random fields instead of engine get_random_256()

* template with compute_root_of_partial_left_tree logic which will be used by multiple tree root cbinds

* unused include in constants, bad import in cbind

* update bb/aztec3

+Exposes functionality to create asynchronous workers that host webassembly.
+The package is generic, but its tests require a barretenberg.wasm.
+They assume that you have a file structure as follows:
+
+- aztec3-packages/yarn-project/wasm-worker
+- barretenberg
+  clone of https://github.com/AztecProtocol/barretenberg
+  which has ./cpp/build-wasm/bin/barretenberg.wasm from running cpp/bootstrap.sh

+/**
+ * To enable asynchronous callbacks from wasm to js, we leverage asyncify.
+ * Https://kripken.github.io/blog/wasm/2019/07/16/asyncify.html.
+ *
+ * This class holds state and logic specific to handling async calls from wasm to js.
+ * A single instance of this class is instantiated as part of BarretenbergWasm.
+ * It allocates some memory for the asyncify stack data and initialises it.
+ *
+ * To make an async call into the wasm, just call `call` the same as in BarretenbergWasm, only it returns a promise.
+ *
+ * To make an async import that will be called from the wasm, wrap a function with the signature:
+ *   my_func(state: AsyncFnState, ...args)
+ * with a call to `wrapImportFn`.
+ * The arguments are whatever the original call arguments were. The addition of AsyncFnState as the first argument
+ * allows for the detection of wether the function is continuing after the the async call has completed.
+ * If `state.continuation` is false, the function should start its async operation and return the promise.
+ * If `state.continuation` is true, the function can get the result from `state.result` perform any finalisation,
+ * and return an (optional) value to the wasm.

+/**
+ * To enable asynchronous callbacks from wasm to js, we leverage asyncify.
+ * Https://kripken.github.io/blog/wasm/2019/07/16/asyncify.html.
+ *
+ * This class holds state and logic specific to handling async calls from wasm to js.
+ * A single instance of this class is instantiated as part of BarretenbergWasm.
+ * It allocates some memory for the asyncify stack data and initialises it.
+ *
+ * To make an async call into the wasm, just call `call` the same as in BarretenbergWasm, only it returns a promise.
+ *
+ * To make an async import that will be called from the wasm, wrap a function with the signature:
+ *   my_func(state: AsyncFnState, ...args)
+ * with a call to `wrapImportFn`.
+ * The arguments are whatever the original call arguments were. The addition of AsyncFnState as the first argument
+ * allows for the detection of wether the function is continuing after the the async call has completed.
+ * If `state.continuation` is false, the function should start its async operation and return the promise.
+ * If `state.continuation` is true, the function can get the result from `state.result` perform any finalisation,
+ * and return an (optional) value to the wasm.

+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or

+
+# Async Map
+
+Much the same as Array.map, only it takes an async fn as an element handler, and ensures that each element handler is executed sequentially. The pattern of `await Promise.all(arr.map(async e => { ... }))` only works if one's happy with each element handler being run concurrently. If one required sequential execution of async fn's, the only alternative was regular loops with mutable state vars. The equivalent with asyncMap: `await asyncMap(arr, async e => { ... })`.
+
+# Mutex
+
+Receives a MutexDatabase and allows for locking it and unlocking it on demand. The DB will remain locked by recursively extending its lock (pinging).
+
+MutexDatabase's interface is comprehended of three methods: `acquireLock`, `extendLock` and `releaseLock`.
+
+`acquireLock` is called when attempting to lock. If it returns truthy, the db will lock and ping until `unlock` is called. If it returns falsy, `untilAcquired` will take precedence in deciding whether the db will retry to lock or not. In case `untilAcquired` is true, the db will try to relock every `tryLockInterval`.
+`extendLock` is called whenever `pingInterval` is fulfilled and the db hasn't been unlocked.
+`releaseLock` is called when the db is unlocked.
+
+TODO: -- Write how to use it!

Various flags can alter the exact behavior of the command:\n\n      - If `-p,--parallel` is set, the commands will be ran in parallel; they'll by default be limited to a number of parallel tasks roughly equal to half your core number, but that can be overridden via `-j,--jobs`, or disabled by setting `-j unlimited`.\n\n      - If `-p,--parallel` and `-i,--interlaced` are both set, Yarn will print the lines from the output as it receives them. If `-i,--interlaced` wasn't set, it would instead buffer the output from each process and print the resulting buffers only after their source processes have exited.\n\n      - If `-t,--topological` is set, Yarn will only run the command after all workspaces that it depends on through the `dependencies` field have successfully finished executing. If `--topological-dev` is set, both the `dependencies` and `devDependencies` fields will be considered when figuring out the wait points.\n\n      - If `-A,--all` is set, Yarn will run the command on all the workspaces of a project. By default yarn runs the command only on current and all its descendant workspaces.\n\n      - If `-R,--recursive` is set, Yarn will find workspaces to run the command on by recursively evaluating `dependencies` and `devDependencies` fields, instead of looking at the `workspaces` fields.\n\n      - If `--from` is set, Yarn will use the packages matching the 'from' glob as the starting point for any recursive search.\n\n      - If `--since` is set, Yarn will only run the command on workspaces that have been modified since the specified ref. By default Yarn will use the refs specified by the `changesetBaseRefs` configuration option.\n\n      - The command may apply to only some workspaces through the use of `--include` which acts as a whitelist. The `--exclude` flag will do the opposite and will be a list of packages that mustn't execute the script. Both flags accept glob patterns (if valid Idents and supported by [micromatch](https://github.com/micromatch/micromatch)). Make sure to escape the patterns, to prevent your own shell from trying to expand them.\n\n      Adding the `-v,--verbose` flag will cause Yarn to print more information; in particular the name of the workspace that generated the output will be printed at the front of each line.\n\n      If the command is `run` and the script being run does not exist the child workspace will be skipped without error.\n    ",examples:[["Publish current and all descendant packages","yarn workspaces foreach npm publish --tolerate-republish"],["Run build script on current and all descendant packages","yarn workspaces foreach run build"],["Run build script on current and all descendant packages in parallel, building package dependencies first","yarn workspaces foreach -pt run build"],["Run build script on several packages and all their dependencies, building dependencies first","yarn workspaces foreach -ptR --from '{workspace-a,workspace-b}' run build"]]});function dr(e,{prefix:r,interlaced:t}){let n=e.createStreamReporter(r),s=new F.miscUtils.DefaultStream;s.pipe(n,{end:!1}),s.on("finish",()=>{n.end()});let i=new Promise(c=>{n.on("finish",()=>{c(s.active)})});if(t)return[s,i];let a=new F.miscUtils.BufferStream;return a.pipe(s,{end:!1}),a.on("finish",()=>{s.end()}),[a,i]}function qn(e,{configuration:r,commandIndex:t,verbose:n}){if(!n)return null;let i=`[${F.structUtils.stringifyIdent(e.locator)}]:`,a=["#2E86AB","#A23B72","#F18F01","#C73E1D","#CCE2A3"],c=a[t%a.length];return F.formatUtils.pretty(r,i,c)}var Kn={commands:[ce,pe]},Wn=Kn;return wr(jn);})();

Subject: [PATCH 160/166] chore: zero-initialize all structs & their members
 and arrays (#233)

* zero-initialize all abi and kernel structs. helper function to zero-init arrays of frs

* revert uint32 assignments to 0

* better struct initialization in app circuits files

* revert bad zero init of string

* dont need to do as much in base utils since structs are sanely zero-initialized

* format comment fix

* use fill to initialize array of fields to zero

Subject: [PATCH 163/166] feat: Kernel fix & test improvements/refactoring
 (#239)

* fix bug in native kernel - contract logic was being skipped

* zero-initialize all abi and kernel structs. helper function to zero-init arrays of frs

* better struct initialization in app circuits files

* dont need to do as much in base utils since structs are sanely zero-initialized

* use fill to initialize array of fields to zero

* fix native private kernel, refactor private kernel tests, add real logic in test setup for computing function/contract tree roots/siblings

* new hash functions

-# This file uses YAML anchors and aliases to prevent repetition of blocks of config:
-# https://support.atlassian.com/bitbucket-cloud/docs/yaml-anchors/

-# Two primary anchors are checkout and setup_env, called as the first step of almost all jobs:
-# - checkout: A custom checkout step to reduce the amount of data downloaded to improve speed.
-# - setup_env: Sets up the common environment used by all build steps.
-#
-# Two CCI executors are used:
-# - docker (small): Used only to launch external EC2 instances for big workloads. It's the cheapest option.
-# - machine (large): Used for building in CCI itself. 4cpus, 15GB has the optimal power/cost ratio.
-#
-# The docker executor uses a custom image build in `build_image`. It's specifically streamlined for fast download
-# with just enough tools to execute the build system, and launch EC2 instances etc.
-#
-# There are some `join` steps that are just noops. They are just used to produce cleaner graph rendering in CCI.

-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
-
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including

-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,

-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,

-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-* `constants.hpp`: top-level constants relevant to Aztec 3
-* `circuits`: circuits and their types and interfaces
-    * `apps`: infrastructure and early prototypes for application circuits ([more here](https://github.com/AztecProtocol/aztec3-circuits/tree/master/cpp/src/aztec3/circuits/apps))
-    * `abis`:  types, interfaces, and cbinds for representing/constructing outputs of application circuits that will be fed into kernel circuits ([more here](https://github.com/AztecProtocol/aztec3-circuits/tree/master/cpp/src/aztec3/circuits/abis))
-    * `kernel`: kernel circuits, their interfaces, and their tests
-    * `rollup`: rollup circuits, their interfaces, and thier tests
-    * `recursion`: types and examples for aggregation of recursive proof objects
-    * `mock`: mock circuits
-* `oracle`: used to fetch external information (like private data notes) and inject them as inputs into the circuit "Composer" during execution of circuit logic ([more here](https://github.com/AztecProtocol/aztec3-circuits/tree/master/cpp/src/aztec3/oracle))

 The private kernel circuit validates that a particular private function was correctly executed by the user. Therefore, the private kernel circuit is going to be run on the user's device. A private function execution can involve calls to other private functions from the same contract or private functions from other contracts. Each call to another private function needs to be proven that the execution was correct. Therefore, each nested call to another private function will have its own circuit execution proof, and that proof must then be validated by the private kernel circuit. The proof generated by the private kernel circuit will be submitted to the transaction pool, from where rollup providers will include those private kernel proofs in their L2 blocks.

 The rollup providers (or sequencers - nomenclature is yet to be decided) pull up transactions from the pool to be rolled up. Each of these transactions is essentially a proof generated by the private kernel circuit including its public inputs. To accumulate several such transactions in a single L2 block, the rollup provider needs to aggregate the private kernel proofs. The base rollup circuit is meant to aggregate these private kernel proofs. In simple words, the rollup circuit validates that the private kernel circuit was correctly executed.
 
-In our design, we allow the rollup providers to only aggregate _two_ private kernel proofs at once. This would mean that if a rollup provider wishes to roll-up 1024 transactions in one L2 block, for example, he would need $\frac{1024}{2} = 512$ invocations of the base rollup circuit. This hard-limit on the number of private kernel proofs that one can aggregate is enable generating rollup proofs on commodity hardware, effectively reducing the entry-barrier for common users to become rollup providers.

 ### Root Rollup Circuit
 
-The root rollup circuit is the final circuit execution layer before the proof is sent to L1 for on-chain verification. The root rollup circuit verifies that the final merge rollup circuit was correctly executed. The proof from the root rollup circuit is verified by the rollup contract on Ethereum. So effectively, verifying that one proof on-chain gives a final green flag to whatever number of transactions that were included in that particular L2 block.

So effectively, verifying that one proof on-chain gives a final green flag to whatever number of transactions that were included in that particular L2 block.
 
 It is interesting to note that the root rollup circuit takes _one_ proof and outputs _one_ proof. The reason we do this is to switch the types of the proof: i.e. ultra-plonk/honk to standard-plonk. This is because standard-plonk proofs are cheaper to verify on-chain (in terms of gas costs).

 ## Circuit Logic

 ### Private Kernel Circuit Logic
 
 The private kernel circuit is recursive in that it will perform validation of a single function call, and then recursively verify its previous iteration along with the next function call.
 
 Below is a list of the private kernel circuit's high-level responsibilities:
+
 1. For the first iteration:
-    * **[M1.1]** Validate the signature of a signed tx object
-    * Validate the function in that tx object matches the one currently being processed
+   - **[M1.1]** Validate the signature of a signed tx object
+   - Validate the function in that tx object matches the one currently being processed
 2. For all subsequent iterations:
-    * Pop an item off of the kernel's dynamic callstack
-    * Validate that this function matches the one currently being processed
-1. Verify a 'previous' kernel circuit (mock for first iteration, always mocked for **[M1.1]**)
-3. Verify the proof of execution for the function (or constructor **[M1.1]**) currently being processed
-4. **[M1.1]** If this is a contract deployment, check the contract deployment logic
-    * _[After M1.1]_ Includes checks for private circuit execution logic
-5. **[M1.1]** Generate `contract_address` and its nullifier (inserted in later circuit)
-6. **[M1.1]** Generate `new_contract_data` which is the contract tree leaf preimage
-7. Copy the current function's callstack into kernel's dynamic callstack
-8. Validate the function data against `function_tree_root`
-    * Includes a membership check of the function leaf
-9. Validate the contract data against `contract_tree_root`
-    * Includes a membership check of the contract leaf
-10. Perform membership checks for commitments accessed by this function
-11. Collect new commitments, nullifiers, contracts, and messages to L1
-12. Add recursion byproducts to `aggregation_object`
-13. TODO: L1 messages
-14. Section in progress...
