In short, you verify one proof *inside* another proof, returning the proof that both proofs are valid. + +This means that, given enough computational resources, you can prove the correctness of any arbitrary number of proofs in a single proof. This could be useful to design state channels (for which a common example would be [Bitcoin's Lightning Network](https://en.wikipedia.org/wiki/Lightning_Network)), to save on gas costs by settling one proof on-chain, or simply to make business logic less dependent on a consensus mechanism. + +## Examples + +Let us look at some of these examples + +### Alice and Bob - Guessing game + +Alice and Bob are friends, and they like guessing games. They want to play a guessing game online, but for that, they need a trusted third-party that knows both of their secrets and finishes the game once someone wins. + +So, they use zero-knowledge proofs. Alice tries to guess Bob's number, and Bob will generate a ZK proof stating whether she succeeded or failed. + +This ZK proof can go on a smart contract, revealing the winner and even giving prizes. However, this means every turn needs to be verified on-chain. This incurs some cost and waiting time that may simply make the game too expensive or time-consuming to be worth it. + +As a solution, Alice proposes the following: "what if Bob generates his proof, and instead of sending it on-chain, I verify it *within* my own proof before playing my own turn?". + +She can then generate a proof that she verified his proof, and so on. + +```md + Did you fail? <-------------------------- + / \ / + / \ n = n -1 + / \ / + Yes No / + | | / + | | / + | You win / + | / + | / +Generate proof of that / + + / + my own guess ---------------- +``` + +### Charlie - Recursive merkle tree + +Charlie is a concerned citizen, and wants to be sure his vote in an election is accounted for. He votes with a ZK proof, but he has no way of knowing that his ZK proof was included in the total vote count! + +If the vote collector puts all of the votes into a [Merkle tree](https://en.wikipedia.org/wiki/Merkle_tree), everyone can prove the verification of two proofs within one proof, as such: + +```md + abcd + __________|______________ + | | + ab cd + _____|_____ ______|______ + | | | | + alice bob charlie daniel +``` + +Doing this recursively allows us to arrive on a final proof `abcd` which if true, verifies the correctness of all the votes. + +### Daniel - Reusable components + +Daniel has a big circuit and a big headache. A part of his circuit is a setup phase that finishes with some assertions that need to be made. But that section alone takes most of the proving time, and is largely independent of the rest of the circuit. + +He might find it more efficient to generate a proof for that setup phase separately, and verify that proof recursively in the actual business logic section of his circuit. This will allow for parallelization of both proofs, which results in a considerable speedup. + +## What params do I need + +As you can see in the [recursion reference](noir/standard_library/recursion.mdx), a simple recursive proof requires: + +- The proof to verify +- The Verification Key of the circuit that generated the proof +- A hash of this verification key, as it's needed for some backends +- The public inputs for the proof + +:::info + +Recursive zkSNARK schemes do not necessarily "verify a proof" in the sense that you expect a true or false to be spit out by the verifier. Rather an aggregation object is built over the public inputs. + +So, taking the example of Alice and Bob and their guessing game: + +- Alice makes her guess. Her proof is *not* recursive: it doesn't verify any proof within it! It's just a standard `assert(x != y)` circuit +- Bob verifies Alice's proof and makes his own guess. In this circuit, he doesn't exactly *prove* the verification of Alice's proof. Instead, he *aggregates* his proof to Alice's proof. The actual verification is done when the full proof is verified, for example when using `nargo verify` or through the verifier smart contract. + +We can imagine recursive proofs a [relay race](https://en.wikipedia.org/wiki/Relay_race). The first runner doesn't have to receive the baton from anyone else, as he/she already starts with it. But when his/her turn is over, the next runner needs to receive it, run a bit more, and pass it along. Even though every runner could theoretically verify the baton mid-run (why not? 🏃🔍), only at the end of the race does the referee verify that the whole race is valid. + +::: + +## Some architecture + +As with everything in computer science, there's no one-size-fits all. But there are some patterns that could help understanding and implementing them. To give three examples: + +### Adding some logic to a proof verification + +This would be an approach for something like our guessing game, where proofs are sent back and forth and are verified by each opponent. This circuit would be divided in two sections: + +- A `recursive verification` section, which would be just the call to `std::verify_proof`, and that would be skipped on the first move (since there's no proof to verify) +- A `guessing` section, which is basically the logic part where the actual guessing happens + +In such a situation, and assuming Alice is first, she would skip the first part and try to guess Bob's number. Bob would then verify her proof on the first section of his run, and try to guess Alice's number on the second part, and so on. + +### Aggregating proofs + +In some one-way interaction situations, recursion would allow for aggregation of simple proofs that don't need to be immediately verified on-chain or elsewhere. + +To give a practical example, a barman wouldn't need to verify a "proof-of-age" on-chain every time he serves alcohol to a customer. Instead, the architecture would comprise two circuits: + +- A `main`, non-recursive circuit with some logic +- A `recursive` circuit meant to verify two proofs in one proof + +The customer's proofs would be intermediate, and made on their phones, and the barman could just verify them locally. He would then aggregate them into a final proof sent on-chain (or elsewhere) at the end of the day. + +### Recursively verifying different circuits + +Nothing prevents you from verifying different circuits in a recursive proof, for example: + +- A `circuit1` circuit +- A `circuit2` circuit +- A `recursive` circuit + +In this example, a regulator could verify that taxes were paid for a specific purchase by aggregating both a `payer` circuit (proving that a purchase was made and taxes were paid), and a `receipt` circuit (proving that the payment was received) + +## How fast is it + +At the time of writing, verifying recursive proofs is surprisingly fast. This is because most of the time is spent on generating the verification key that will be used to generate the next proof.

Using smaller value types, and bit-packing strategies, will result in MORE gates +::: + + +### Use Arithmetic over non-arithmetic operations + +Since circuits are made of arithmetic gates, the cost of arithmetic operations tends to be one gate. Whereas for procedural code, they represent several clock cycles. + +Inversely, non-arithmetic operators are achieved with multiple gates, vs 1 clock cycle for procedural code. + +| (cost\op) | arithmetic

Arrays of fixed length (albeit used at a lower capacity), will generate less gates than dynamic storage. + +Related to this, if an index used to access an array is not known at compile time (ie unknown until run time), then ROM will be converted to RAM, expanding the gate count. + +:::tip +Use arrays and indices that are known at compile time where possible. +Using `assert_constant(i);` before an index, `i`, is used in an array will give a compile error if `i` is NOT known at compile time. +::: + +### Leverage unconstrained execution + +Constrained verification can leverage unconstrained execution, this is especially useful for operations that are represented by many gates. +Use an [unconstrained function](../noir/concepts/unconstrained.md) to perform gate-heavy calculations, then verify and constrain the result. + +Eg division generates more gates than multiplication, so calculating the quotient in an unconstrained function then constraining the product for the quotient and divisor (+ any remainder) equals the dividend will be more efficient. + +Use ` if is_unconstrained() { /`, to conditionally execute code if being called in an unconstrained vs constrained way. + +## Advanced + +Unless you're well into the depth of gate optimization, this advanced section can be ignored. + +### Combine arithmetic operations + +A Noir program can be honed further by combining arithmetic operators in a way that makes the most of each constraint of the backend proving system. This is in scenarios where the backend might not be doing this perfectly. + +Eg Barretenberg backend (current default for Noir) is a width-4 PLONKish constraint system +$ w_1*w_2*q_m + w_1*q_1 + w_2*q_2 + w_3*q_3 + w_4*q_4 + q_c = 0 $ + +Here we see there is one occurrence of witness 1 and 2 ($w_1$, $w_2$) being multiplied together, with addition to witnesses 1-4 ($w_1$ .. $w_4$) multiplied by 4 corresponding circuit constants ($q_1$ .. $q_4$) (plus a final circuit constant, $q_c$). + +Use `nargo info --print-acir`, to inspect the ACIR opcodes (and the proving system for gates), and it may present opportunities to amend the order of operations and reduce the number of constraints. + +#### Variable as witness vs expression + +If you've come this far and really know what you're doing at the equation level, a temporary lever (that will become unnecessary/useless over time) is: `std::as_witness`. This informs the compiler to save a variable as a witness not an expression. + +The compiler will mostly be correct and optimal, but this may help some near term edge cases that are yet to optimize. +Note: When used incorrectly it will create **less** efficient circuits (higher gate count). + +## References +- Guillaume's ["`Cryptdoku`" talk](https://www.youtube.com/watch?v=MrQyzuogxgg) (Jun'23) +- Tips from Tom, Jake and Zac. +- [Idiomatic Noir](https://www.vlayer.xyz/blog/idiomatic-noir-part-1-collections) blog post diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.35.0/getting_started/_category_.json b/noir/noir-repo/docs/versioned_docs/version-v0.35.0/getting_started/_category_.json new file mode 100644 index 00000000000..5d694210bbf --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.35.0/getting_started/_category_.json @@ -0,0 +1,5 @@ +{ + "position": 0, + "collapsible": true, + "collapsed": true +} diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.35.0/getting_started/backend/_category_.json b/noir/noir-repo/docs/versioned_docs/version-v0.35.0/getting_started/backend/_category_.json new file mode 100644 index 00000000000..b82e92beb0c --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.35.0/getting_started/backend/_category_.json @@ -0,0 +1,6 @@ +{ + "position": 1, + "label": "Install Proving Backend", + "collapsible": true, + "collapsed": true +} diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.35.0/getting_started/backend/index.md b/noir/noir-repo/docs/versioned_docs/version-v0.35.0/getting_started/backend/index.md new file mode 100644 index 00000000000..7192d954877 --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.35.0/getting_started/backend/index.md @@ -0,0 +1,31 @@ +--- +title: Proving Backend Installation +description: Proving backends offer command line tools for proving and verifying Noir programs.

How to modify our Noir program to make use of oracle calls as unconstrained functions +2. How to write a JSON RPC Server to resolve these oracle calls with Nargo +3. How to use them in Nargo and how to provide a custom resolver in NoirJS + +## Step 1 - Modify your Noir program + +An oracle is defined in a Noir program by defining two methods: + +- An unconstrained method - This tells the compiler that it is executing an [unconstrained functions](../noir/concepts//unconstrained.md). +- A decorated oracle method - This tells the compiler that this method is an RPC call. + +An example of an oracle that returns a `Field` would be: + +```rust +#[oracle(getSqrt)] +unconstrained fn sqrt(number: Field) -> Field { } + +unconstrained fn get_sqrt(number: Field) -> Field { + sqrt(number) +} +``` + +In this example, we're wrapping our oracle function in an unconstrained method, and decorating it with `oracle(getSqrt)`. We can then call the unconstrained function as we would call any other function: + +```rust +fn main(input: Field) { + let sqrt = get_sqrt(input); +} +``` + +In the next section, we will make this `getSqrt` (defined on the `sqrt` decorator) be a method of the RPC server Noir will use. + +:::danger + +As explained in the [Oracle Explainer](../explainers/explainer-oracle.md), this `main` function is unsafe unless you constrain its return value. For example: + +```rust +fn main(input: Field) { + let sqrt = get_sqrt(input); + assert(sqrt.pow_32(2) as u64 == input as u64); // <---- constrain the return of an oracle! +} +``` + +::: + +:::info + +Currently, oracles only work with single params or array params. For example: + +```rust +#[oracle(getSqrt)] +unconstrained fn sqrt([Field; 2]) -> [Field; 2] { } +``` + +::: + +## Step 2 - Write an RPC server + +Brillig will call *one* RPC server. Most likely you will have to write your own, and you can do it in whatever language you prefer. In this guide, we will do it in Javascript. + +Let's use the above example of an oracle that consumes an array with two `Field` and returns their square roots: + +```rust +#[oracle(getSqrt)] +unconstrained fn sqrt(input: [Field; 2]) -> [Field; 2] { } + +unconstrained fn get_sqrt(input: [Field; 2]) -> [Field; 2] { + sqrt(input) +} + +fn main(input: [Field; 2]) { + let sqrt = get_sqrt(input); + assert(sqrt[0].pow_32(2) as u64 == input[0] as u64); + assert(sqrt[1].pow_32(2) as u64 == input[1] as u64); +} +``` + +:::info + +Why square root? + +In general, computing square roots is computationally more expensive than multiplications, which takes a toll when speaking about ZK applications. In this case, instead of calculating the square root in Noir, we are using our oracle to offload that computation to be made in plain. In our circuit we can simply multiply the two values. + +::: + +Now, we should write the correspondent RPC server, starting with the [default JSON-RPC 2.0 boilerplate](https://www.npmjs.com/package/json-rpc-2.0#example): + +```js +import { JSONRPCServer } from "json-rpc-2.0"; +import express from "express"; +import bodyParser from "body-parser"; + +const app = express(); +app.use(bodyParser.json()); + +const server = new JSONRPCServer(); +app.post("/", (req, res) => { + const jsonRPCRequest = req.body; + server.receive(jsonRPCRequest).then((jsonRPCResponse) => { + if (jsonRPCResponse) { + res.json(jsonRPCResponse); + } else { + res.sendStatus(204); + } + }); +}); + +app.listen(5555); +``` + +Now, we will add our `getSqrt` method, as expected by the `#[oracle(getSqrt)]` decorator in our Noir code. It maps through the params array and returns their square roots: + +```js +server.addMethod("resolve_function_call", async (params) => { + if params.function !== "getSqrt" { + throw Error("Unexpected foreign call") + }; + const values = params.inputs[0].Array.map((field) => { + return `${Math.sqrt(parseInt(field, 16))}`; + }); + return { values: [{ Array: values }] }; +}); +``` + +If you're using Typescript, the following types may be helpful in understanding the expected return value and making sure they're easy to follow: + +```js +interface SingleForeignCallParam { + Single: string, +} + +interface ArrayForeignCallParam { + Array: string[], +} + +type ForeignCallParam = SingleForeignCallParam | ArrayForeignCallParam; + +interface ForeignCallResult { + values: ForeignCallParam[], +} +``` + +::: Multidimensional Arrays + +If the Oracle function is returning an array containing other arrays, such as `[['1','2],['3','4']]`, you need to provide the values in json as flattened values. In the previous example, it would be `['1', '2', '3', '4']`. In the noir program, the Oracle signature can use a nested type, the flattened values will be automatically converted to the nested type. + +::: + +## Step 3 - Usage with Nargo + +Using the [`nargo` CLI tool](../getting_started/installation/index.md), you can use oracles in the `nargo test` and `nargo execute` commands by passing a value to `--oracle-resolver`. For example: + +```bash +nargo test --oracle-resolver http://localhost:5555 +``` + +This tells `nargo` to use your RPC Server URL whenever it finds an oracle decorator. + +## Step 4 - Usage with NoirJS + +In a JS environment, an RPC server is not strictly necessary, as you may want to resolve your oracles without needing any JSON call at all. NoirJS simply expects that you pass a callback function when you generate proofs, and that callback function can be anything. + +For example, if your Noir program expects the host machine to provide CPU pseudo-randomness, you could simply pass it as the `foreignCallHandler`. You don't strictly need to create an RPC server to serve pseudo-randomness, as you may as well get it directly in your app: + +```js +const foreignCallHandler = (name, inputs) => crypto.randomBytes(16) // etc + +await noir.execute(inputs, foreignCallHandler) +``` + +As one can see, in NoirJS, the [`foreignCallHandler`](../reference/NoirJS/noir_js/type-aliases/ForeignCallHandler.md) function simply means "a callback function that returns a value of type [`ForeignCallOutput`](../reference/NoirJS/noir_js/type-aliases/ForeignCallOutput.md). It doesn't have to be an RPC call like in the case for Nargo. + +:::tip + +Does this mean you don't have to write an RPC server like in [Step #2](#step-2---write-an-rpc-server)? + +You don't technically have to, but then how would you run `nargo test`? To use both `Nargo` and `NoirJS` in your development flow, you will have to write a JSON RPC server. + +::: + +In this case, let's make `foreignCallHandler` call the JSON RPC Server we created in [Step #2](#step-2---write-an-rpc-server), by making it a JSON RPC Client. + +For example, using the same `getSqrt` program in [Step #1](#step-1---modify-your-noir-program) (comments in the code): + +```js +import { JSONRPCClient } from "json-rpc-2.0"; + +// declaring the JSONRPCClient +const client = new JSONRPCClient((jsonRPCRequest) => { +// hitting the same JSON RPC Server we coded above + return fetch("http://localhost:5555", { + method: "POST", + headers: { + "content-type": "application/json", + }, + body: JSON.stringify(jsonRPCRequest), + }).then((response) => { + if (response.status === 200) { + return response + .json() + .then((jsonRPCResponse) => client.receive(jsonRPCResponse)); + } else if (jsonRPCRequest.id !== undefined) { + return Promise.reject(new Error(response.statusText)); + } + }); +}); + +// declaring a function that takes the name of the foreign call (getSqrt) and the inputs +const foreignCallHandler = async (name, input) => { + // notice that the "inputs" parameter contains *all* the inputs + // in this case we make the RPC request with the first parameter "numbers", which would be input[0] + const oracleReturn = await client.request(name, [ + input[0].map((i) => i.toString("hex")), + ]); + return { values: oracleReturn }; +}; + +// the rest of your NoirJS code +const input = { input: [4, 16] }; +const { witness } = await noir.execute(numbers, foreignCallHandler); +``` + +:::tip + +If you're in a NoirJS environment running your RPC server together with a frontend app, you'll probably hit a familiar problem in full-stack development: requests being blocked by [CORS](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS) policy.

We will *not* be using it as a reference for this guide. + +## Step 1: Setup + +In a common NoirJS app, you need to instantiate a backend with something like `const backend = new Backend(circuit)`. Then you feed it to the `noir_js` interface. + +For recursion, this doesn't happen, and the only need for `noir_js` is only to `execute` a circuit and get its witness and return value. Everything else is not interfaced, so it needs to happen on the `backend` object. + +It is also recommended that you instantiate the backend with as many threads as possible, to allow for maximum concurrency: + +```js +const backend = new Backend(circuit, { threads: 8 }) +``` + +:::tip +You can use the [`os.cpus()`](https://nodejs.org/api/os.html#oscpus) object in `nodejs` or [`navigator.hardwareConcurrency`](https://developer.mozilla.org/en-US/docs/Web/API/Navigator/hardwareConcurrency) on the browser to make the most out of those glorious cpu cores +::: + +## Step 2: Generating the witness and the proof for `main` + +After instantiating the backend, you should also instantiate `noir_js`. We will use it to execute the circuit and get the witness. + +```js +const noir = new Noir(circuit) +const { witness } = noir.execute(input) +``` + +With this witness, you are now able to generate the intermediate proof for the main circuit: + +```js +const { proof, publicInputs } = await backend.generateProof(witness) +``` + +:::warning + +Always keep in mind what is actually happening on your development process, otherwise you'll quickly become confused about what circuit we are actually running and why! + +In this case, you can imagine that Alice (running the `main` circuit) is proving something to Bob (running the `recursive` circuit), and Bob is verifying her proof within his proof. + +With this in mind, it becomes clear that our intermediate proof is the one *meant to be verified within another circuit*, so it must be Alice's. Actually, the only final proof in this theoretical scenario would be the last one, sent on-chain. + +::: + +## Step 3 - Verification and proof artifacts + +Optionally, you are able to verify the intermediate proof: + +```js +const verified = await backend.verifyProof({ proof, publicInputs }) +``` + +This can be useful to make sure our intermediate proof was correctly generated. But the real goal is to do it within another circuit. For that, we need to generate recursive proof artifacts that will be passed to the circuit that is verifying the proof we just generated. Instead of passing the proof and verification key as a byte array, we pass them as fields which makes it cheaper to verify in a circuit: + +```js +const { proofAsFields, vkAsFields, vkHash } = await backend.generateRecursiveProofArtifacts( { publicInputs, proof }, publicInputsCount) +``` + +This call takes the public inputs and the proof, but also the public inputs count. While this is easily retrievable by simply counting the `publicInputs` length, the backend interface doesn't currently abstract it away. + +:::info + +The `proofAsFields` has a constant size `[Field; 93]` and verification keys in Barretenberg are always `[Field; 114]`. + +::: + +:::warning + +One common mistake is to forget *who* makes this call. + +In a situation where Alice is generating the `main` proof, if she generates the proof artifacts and sends them to Bob, which gladly takes them as true, this would mean Alice could prove anything! + +Instead, Bob needs to make sure *he* extracts the proof artifacts, using his own instance of the `main` circuit backend. This way, Alice has to provide a valid proof for the correct `main` circuit. + +::: + +## Step 4 - Recursive proof generation + +With the artifacts, generating a recursive proof is no different from a normal proof. You simply use the `backend` (with the recursive circuit) to generate it: + +```js +const recursiveInputs = { + verification_key: vkAsFields, // array of length 114 + proof: proofAsFields, // array of length 93 + size of public inputs + publicInputs: [mainInput.y], // using the example above, where `y` is the only public input + key_hash: vkHash, +} + +const { witness, returnValue } = noir.execute(recursiveInputs) // we're executing the recursive circuit now! +const { proof, publicInputs } = backend.generateProof(witness) +const verified = backend.verifyProof({ proof, publicInputs }) +``` + +You can obviously chain this proof into another proof.

It is assumed that: + +- You are comfortable with the Solidity programming language and understand how contracts are deployed on the Ethereum network +- You have Noir installed and you have a Noir program.

However, compiling it and deploying it can have some caveats. Here's the rundown of this guide: + +1. How to generate a solidity smart contract +2. How to compile the smart contract in the RemixIDE +3. How to deploy it to a testnet + +## Step 1 - Generate a contract + +This is by far the most straightforward step. Just run: + +```sh +nargo compile +``` + +This will compile your source code into a Noir build artifact to be stored in the `./target` directory, you can then generate the smart contract using the commands: + +```sh +# Here we pass the path to the newly generated Noir artifact. +bb write_vk -b ./target/.json +bb contract +``` + +replacing `` with the name of your Noir project. A new `contract` folder would then be generated in your project directory, containing the Solidity +file `contract.sol`. It can be deployed to any EVM blockchain acting as a verifier smart contract. + +You can find more information about `bb` and the default Noir proving backend on [this page](../getting_started/hello_noir/index.md#proving-backend). + +:::info + +It is possible to generate verifier contracts of Noir programs for other smart contract platforms as long as the proving backend supplies an implementation. + +Barretenberg, the default proving backend for Nargo, supports generation of verifier contracts, for the time being these are only in Solidity. +::: + +## Step 2 - Compiling + +We will mostly skip the details of RemixIDE, as the UI can change from version to version. For now, we can just open +Remix and create a blank workspace. + +![Create Workspace](@site/static/img/how-tos/solidity_verifier_1.png) + +We will create a new file to contain the contract Nargo generated, and copy-paste its content. + +:::warning + +You'll likely see a warning advising you to not trust pasted code. While it is an important warning, it is irrelevant in the context of this guide and can be ignored. We will not be deploying anywhere near a mainnet. + +::: + +To compile our the verifier, we can navigate to the compilation tab: + +![Compilation Tab](@site/static/img/how-tos/solidity_verifier_2.png) + +Remix should automatically match a suitable compiler version. However, hitting the "Compile" button will most likely generate a "Stack too deep" error: + +![Stack too deep](@site/static/img/how-tos/solidity_verifier_3.png) + +This is due to the verify function needing to put many variables on the stack, but enabling the optimizer resolves the issue. To do this, let's open the "Advanced Configurations" tab and enable optimization. The default 200 runs will suffice. + +:::info + +This time we will see a warning about an unused function parameter. This is expected, as the `verify` function doesn't use the `_proof` parameter inside a solidity block, it is loaded from calldata and used in assembly. + +::: + +![Compilation success](@site/static/img/how-tos/solidity_verifier_4.png) + +## Step 3 - Deploying + +At this point we should have a compiled contract ready to deploy. If we navigate to the deploy section in Remix, we will see many different environments we can deploy to. The steps to deploy on each environment would be out-of-scope for this guide, so we will just use the default Remix VM. + +Looking closely, we will notice that our "Solidity Verifier" is actually three contracts working together: + +- An `UltraVerificationKey` library which simply stores the verification key for our circuit. +- An abstract contract `BaseUltraVerifier` containing most of the verifying logic. +- A main `UltraVerifier` contract that inherits from the Base and uses the Key contract. + +Remix will take care of the dependencies for us so we can simply deploy the UltraVerifier contract by selecting it and hitting "deploy": + +![Deploying UltraVerifier](@site/static/img/how-tos/solidity_verifier_5.png) + +A contract will show up in the "Deployed Contracts" section, where we can retrieve the Verification Key Hash. This is particularly useful for double-checking that the deployer contract is the correct one. + +:::note + +Why "UltraVerifier"? + +To be precise, the Noir compiler (`nargo`) doesn't generate the verifier contract directly. It compiles the Noir code into an intermediate language (ACIR), which is then executed by the backend. So it is the backend that returns the verifier smart contract, not Noir. + +In this case, the Barretenberg Backend uses the UltraPlonk proving system, hence the "UltraVerifier" name. + +::: + +## Step 4 - Verifying + +To verify a proof using the Solidity verifier contract, we call the `verify` function in this extended contract: + +```solidity +function verify(bytes calldata _proof, bytes32[] calldata _publicInputs) external view returns (bool) +``` + +When using the default example in the [Hello Noir](../getting_started/hello_noir/index.md) guide, the easiest way to confirm that the verifier contract is doing its job is by calling the `verify` function via remix with the required parameters. Note that the public inputs must be passed in separately to the rest of the proof so we must split the proof as returned from `bb`. + +First generate a proof with `bb` at the location `./proof` using the steps in [get started](../getting_started/hello_noir/index.md), this proof is in a binary format but we want to convert it into a hex string to pass into Remix, this can be done with the + +```bash +# This value must be changed to match the number of public inputs (including return values!) in your program. +NUM_PUBLIC_INPUTS=1 +PUBLIC_INPUT_BYTES=32*NUM_PUBLIC_INPUTS +HEX_PUBLIC_INPUTS=$(head -c $PUBLIC_INPUT_BYTES ./proof | od -An -v -t x1 | tr -d $' \n') +HEX_PROOF=$(tail -c +$(($PUBLIC_INPUT_BYTES + 1)) ./proof | od -An -v -t x1 | tr -d $' \n') + +echo "Public inputs:" +echo $HEX_PUBLIC_INPUTS + +echo "Proof:" +echo "0x$HEX_PROOF" +``` + +Remix expects that the public inputs will be split into an array of `bytes32` values so `HEX_PUBLIC_INPUTS` needs to be split up into 32 byte chunks which are prefixed with `0x` accordingly. + +A programmatic example of how the `verify` function is called can be seen in the example zk voting application [here](https://github.com/noir-lang/noir-examples/blob/33e598c257e2402ea3a6b68dd4c5ad492bce1b0a/foundry-voting/src/zkVote.sol#L35): + +```solidity +function castVote(bytes calldata proof, uint proposalId, uint vote, bytes32 nullifierHash) public returns (bool) { + // ... + bytes32[] memory publicInputs = new bytes32[](4); + publicInputs[0] = merkleRoot; + publicInputs[1] = bytes32(proposalId); + publicInputs[2] = bytes32(vote); + publicInputs[3] = nullifierHash; + require(verifier.verify(proof, publicInputs), "Invalid proof"); +``` + +:::info[Return Values] + +A circuit doesn't have the concept of a return value. Return values are just syntactic sugar in Noir. + +Under the hood, the return value is passed as an input to the circuit and is checked at the end of the circuit program. + +For example, if you have Noir program like this: + +```rust +fn main( + // Public inputs + pubkey_x: pub Field, + pubkey_y: pub Field, + // Private inputs + priv_key: Field, +) -> pub Field +``` + +the `verify` function will expect the public inputs array (second function parameter) to be of length 3, the two inputs and the return value. + +Passing only two inputs will result in an error such as `PUBLIC_INPUT_COUNT_INVALID(3, 2)`. + +In this case, the inputs parameter to `verify` would be an array ordered as `[pubkey_x, pubkey_y, return`. + +::: + +:::tip[Structs] + +You can pass structs to the verifier contract. They will be flattened so that the array of inputs is 1-dimensional array. + +For example, consider the following program: + +```rust +struct Type1 { + val1: Field, + val2: Field, +} + +struct Nested { + t1: Type1, + is_true: bool, +} + +fn main(x: pub Field, nested: pub Nested, y: pub Field) { + //... +} +``` + +The order of these inputs would be flattened to: `[x, nested.t1.val1, nested.t1.val2, nested.is_true, y]` + +::: + +The other function you can call is our entrypoint `verify` function, as defined above. + +:::tip + +It's worth noticing that the `verify` function is actually a `view` function. A `view` function does not alter the blockchain state, so it doesn't need to be distributed (i.e. it will run only on the executing node), and therefore doesn't cost any gas. + +This can be particularly useful in some situations. If Alice generated a proof and wants Bob to verify its correctness, Bob doesn't need to run Nargo, NoirJS, or any Noir specific infrastructure. He can simply make a call to the blockchain with the proof and verify it is correct without paying any gas. + +It would be incorrect to say that a Noir proof verification costs any gas at all. However, most of the time the result of `verify` is used to modify state (for example, to update a balance, a game state, etc). In that case the whole network needs to execute it, which does incur gas costs (calldata and execution, but not storage). + +::: + +## A Note on EVM chains + +Noir proof verification requires the ecMul, ecAdd and ecPairing precompiles. Not all EVM chains support EC Pairings, notably some of the ZK-EVMs. This means that you won't be able to use the verifier contract in all of them. You can find an incomplete list of which EVM chains support these precompiles [here](https://www.evmdiff.com/features?feature=precompiles). + +For example, chains like `zkSync ERA` and `Polygon zkEVM` do not currently support these precompiles, so proof verification via Solidity verifier contracts won't work. Here's a quick list of EVM chains that have been tested and are known to work: + +- Optimism +- Arbitrum +- Polygon PoS +- Scroll +- Celo +- BSC +- Blast L2 +- Avalanche C-Chain +- Mode +- Linea +- Moonbeam + +If you test any other chains, please open a PR on this page to update the list. See [this doc](https://github.com/noir-lang/noir-starter/tree/main/with-foundry#testing-on-chain) for more info about testing verifier contracts on different EVM chains. + +## What's next + +Now that you know how to call a Noir Solidity Verifier on a smart contract using Remix, you should be comfortable with using it with some programmatic frameworks, such as [hardhat](https://github.com/noir-lang/noir-starter/tree/main/vite-hardhat) and [foundry](https://github.com/noir-lang/noir-starter/tree/main/with-foundry). + +You can find other tools, examples, boilerplates and libraries in the [awesome-noir](https://github.com/noir-lang/awesome-noir) repository. + +You should also be ready to write and deploy your first NoirJS app and start generating proofs on websites, phones, and NodeJS environments!

Quoting and unquoting +3. The metaprogramming API in `std::meta` + +Each of these are explained in more detail in the next sections but the wide picture is that +`comptime` allows us to write code which runs at compile-time. In this `comptime` code we +can quote and unquote snippets of the program, manipulate them, and insert them in other +parts of the program. Comptime functions which do this are said to be macros. Additionally, +there's a compile-time API of built-in types and functions provided by the compiler which allows +for greater analysis and modification of programs. + +--- + +# Comptime + +`comptime` is a new keyword in Noir which marks an item as executing or existing at compile-time. It can be used in several ways: + +- `comptime fn` to define functions which execute exclusively during compile-time. +- `comptime global` to define a global variable which is evaluated at compile-time. + - Unlike runtime globals, `comptime global`s can be mutable. +- `comptime { ... }` to execute a block of statements during compile-time. +- `comptime let` to define a variable whose value is evaluated at compile-time. +- `comptime for` to run a for loop at compile-time. Syntax sugar for `comptime { for .. }`. + +## Scoping + +Note that while in a `comptime` context, any runtime variables _local to the current function_ are never visible. + +## Evaluating + +Evaluation rules of `comptime` follows the normal unconstrained evaluation rules for other Noir code. There are a few things to note though: + +- Certain built-in functions may not be available, although more may be added over time. +- Evaluation order of global items is currently unspecified. For example, given the following two functions we can't guarantee +which `println` will execute first. The ordering of the two printouts will be arbitrary, but should be stable across multiple compilations with the same `nargo` version as long as the program is also unchanged. + +```rust +fn one() { + comptime { println("one"); } +} + +fn two() { + comptime { println("two"); } +} +``` + +- Since evaluation order is unspecified, care should be taken when using mutable globals so that they do not rely on a particular ordering. +For example, using globals to generate unique ids should be fine but relying on certain ids always being produced (especially after edits to the program) should be avoided. +- Although most ordering of globals is unspecified, two are: + - Dependencies of a crate will always be evaluated before the dependent crate. + - Any annotations on a function will be run before the function itself is resolved. This is to allow the annotation to modify the function if necessary. Note that if the + function itself was called at compile-time previously, it will already be resolved and cannot be modified. To prevent accidentally calling functions you wish to modify + at compile-time, it may be helpful to sort your `comptime` annotation functions into a different crate along with any dependencies they require. + +## Lowering + +When a `comptime` value is used in runtime code it must be lowered into a runtime value. This means replacing the expression with the literal that it evaluated to. For example, the code: + +```rust +struct Foo { array: [Field; 2], len: u32 } + +fn main() { + println(comptime { + let mut foo = std::mem::zeroed::(); + foo.array[0] = 4; + foo.len = 1; + foo + }); +} +``` + +will be converted to the following after `comptime` expressions are evaluated: + +```rust +struct Foo { array: [Field; 2], len: u32 } + +fn main() { + println(Foo { array: [4, 0], len: 1 }); +} +``` + +Not all types of values can be lowered. For example, `Type`s and `TypeDefinition`s (among other types) cannot be lowered at all. + +```rust +fn main() { + // There's nothing we could inline here to create a Type value at runtime + // let _ = get_type!(); +} + +comptime fn get_type() -> Type { ... } +``` + +--- + +# (Quasi) Quote + +Macros in Noir are `comptime` functions which return code as a value which is inserted into the call site when it is lowered there. +A code value in this case is of type `Quoted` and can be created by a `quote { ... }` expression. +More specifically, the code value `quote` creates is a token stream - a representation of source code as a series of words, numbers, string literals, or operators. +For example, the expression `quote { Hi "there reader"! }` would quote three tokens: the word "hi", the string "there reader", and an exclamation mark. +You'll note that snippets that would otherwise be invalid syntax can still be quoted. + +When a `Quoted` value is used in runtime code, it is lowered into a `quote { ... }` expression. Since this expression is only valid +in compile-time code however, we'd get an error if we tried this. Instead, we can use macro insertion to insert each token into the +program at that point, and parse it as an expression. To do this, we have to add a `!` after the function name returning the `Quoted` value. +If the value was created locally and there is no function returning it, `std::meta::unquote!(_)` can be used instead. +Calling such a function at compile-time without `!` will just return the `Quoted` value to be further manipulated. For example: + +```rust title="quote-example" showLineNumbers +comptime fn quote_one() -> Quoted { + quote { 1 } + } + + #[test] + fn returning_versus_macro_insertion() { + comptime + { + // let _a: Quoted = quote { 1 }; + let _a: Quoted = quote_one(); + + // let _b: Field = 1; + let _b: Field = quote_one!(); + + // Since integers default to fields, if we + // want a different type we have to explicitly cast + // let _c: i32 = 1 as i32; + let _c: i32 = quote_one!() as i32; + } + } +``` +> Source code: noir_stdlib/src/meta/mod.nr#L121-L142 + + +For those familiar with quoting from other languages (primarily lisps), Noir's `quote` is actually a _quasiquote_. +This means we can escape the quoting by using the unquote operator to splice values in the middle of quoted code. + +# Unquote + +The unquote operator `$` is usable within a `quote` expression. +It takes a variable as an argument, evaluates the variable, and splices the resulting value into the quoted token stream at that point. For example, + +```rust +comptime { + let x = 1 + 2; + let y = quote { $x + 4 }; +} +``` + +The value of `y` above will be the token stream containing `3`, `+`, and `4`. We can also use this to combine `Quoted` values into larger token streams: + +```rust +comptime { + let x = quote { 1 + 2 }; + let y = quote { $x + 4 }; +} +``` + +The value of `y` above is now the token stream containing five tokens: `1 + 2 + 4`. + +Note that to unquote something, a variable name _must_ follow the `$` operator in a token stream. +If it is an expression (even a parenthesized one), it will do nothing. Most likely a parse error will be given when the macro is later unquoted. + +Unquoting can also be avoided by escaping the `$` with a backslash: + +``` +comptime { + let x = quote { 1 + 2 }; + + // y contains the four tokens: `$x + 4` + let y = quote { \$x + 4 }; +} +``` + +--- + +# Annotations + +Annotations provide a way to run a `comptime` function on an item in the program. +When you use an annotation, the function with the same name will be called with that item as an argument: + +```rust +#[my_struct_annotation] +struct Foo {} + +comptime fn my_struct_annotation(s: StructDefinition) { + println("Called my_struct_annotation!"); +} + +#[my_function_annotation] +fn foo() {} + +comptime fn my_function_annotation(f: FunctionDefinition) { + println("Called my_function_annotation!"); +} +``` + +Anything returned from one of these functions will be inserted at top-level along with the original item. +Note that expressions are not valid at top-level so you'll get an error trying to return `3` or similar just as if you tried to write a program containing `3; struct Foo {}`. +You can insert other top-level items such as trait impls, structs, or functions this way though. +For example, this is the mechanism used to insert additional trait implementations into the program when deriving a trait impl from a struct: + +```rust title="derive-field-count-example" showLineNumbers +trait FieldCount { + fn field_count() -> u32; + } + + #[derive_field_count] + struct Bar { x: Field, y: [Field; 2] } + + comptime fn derive_field_count(s: StructDefinition) -> Quoted { + let typ = s.as_type(); + let field_count = s.fields().len(); + quote { + impl FieldCount for $typ { + fn field_count() -> u32 { + $field_count + } + } + } + } +``` +> Source code: noir_stdlib/src/meta/mod.nr#L144-L163 + + +## Calling annotations with additional arguments + +Arguments may optionally be given to annotations. +When this is done, these additional arguments are passed to the annotation function after the item argument. + +```rust title="annotation-arguments-example" showLineNumbers +#[assert_field_is_type(quote { i32 }.as_type())] + struct MyStruct { my_field: i32 } + + comptime fn assert_field_is_type(s: StructDefinition, typ: Type) { + // Assert the first field in `s` has type `typ` + let fields = s.fields(); + assert_eq(fields[0].1, typ); + } +``` +> Source code: noir_stdlib/src/meta/mod.nr#L165-L174 + + +We can also take any number of arguments by adding the `varargs` annotation: + +```rust title="annotation-varargs-example" showLineNumbers +#[assert_three_args(1, 2, 3)] + struct MyOtherStruct { my_other_field: u32 } + + #[varargs] + comptime fn assert_three_args(_s: StructDefinition, args: [Field]) { + assert_eq(args.len(), 3); + } +``` +> Source code: noir_stdlib/src/meta/mod.nr#L176-L184 + + +--- + +# Comptime API + +Although `comptime`, `quote`, and unquoting provide a flexible base for writing macros, +Noir's true metaprogramming ability comes from being able to interact with the compiler through a compile-time API. +This API can be accessed through built-in functions in `std::meta` as well as on methods of several `comptime` types. + +The following is an incomplete list of some `comptime` types along with some useful methods on them. + +- `Quoted`: A token stream +- `Type`: The type of a Noir type + - `fn implements(self, constraint: TraitConstraint) -> bool` + - Returns true if `self` implements the given trait constraint +- `Expr`: A syntactically valid expression.

By default +these functions will resolve in the current function's scope which is usually the attribute function they are called in. +If you're working on a library however, this may be a completely different module or crate to the item you're trying to +use the attribute on. If you want to be able to use `Quoted::as_type` to refer to types local to the caller's scope for +example, you can annotate your attribute function with `#[use_callers_scope]`. This will ensure your attribute, and any +closures it uses, can refer to anything in the caller's scope. `#[use_callers_scope]` also works recursively.

For example, we can specify that a field in a +struct will be of a certain generic type. In this case `value` is of type `T`. + +```rust +struct RepeatedValue { + value: T, + count: Field, +} + +impl RepeatedValue { + fn print(self) { + for _i in 0 .. self.count { + println(self.value); + } + } +} + +fn main() { + let repeated = RepeatedValue { value: "Hello!", count: 2 }; + repeated.print(); +} +``` + +The `print` function will print `Hello!` an arbitrary number of times, twice in this case. + +## Calling functions on generic parameters + +Since a generic type `T` can represent any type, how can we call functions on the underlying type? +In other words, how can we go from "any type `T`" to "any type `T` that has certain methods available?" + +This is what [traits](../concepts/traits.md) are for in Noir. Here's an example of a function generic over +any type `T` that implements the `Eq` trait for equality: + +```rust +fn first_element_is_equal(array1: [T; N], array2: [T; N]) -> bool + where T: Eq +{ + if (array1.len() == 0) | (array2.len() == 0) { + true + } else { + array1[0] == array2[0] + } +} + +fn main() { + assert(first_element_is_equal([1, 2, 3], [1, 5, 6])); + + // We can use first_element_is_equal for arrays of any type + // as long as we have an Eq impl for the types we pass in + let array = [MyStruct::new(), MyStruct::new()]; + assert(array_eq(array, array, MyStruct::eq)); +} + +impl Eq for MyStruct { + fn eq(self, other: MyStruct) -> bool { + self.foo == other.foo + } +} +``` + +You can find more details on traits and trait implementations on the [traits page](../concepts/traits.md). + +## Manually Specifying Generics with the Turbofish Operator + +There are times when the compiler cannot reasonably infer what type should be used for a generic, or when the developer themselves may want to manually distinguish generic type parameters. This is where the `::<>` turbofish operator comes into play. + +The `::<>` operator can follow a variable or path and can be used to manually specify generic arguments within the angle brackets. +The name "turbofish" comes from that `::<>` looks like a little fish. + +Examples: +```rust +fn main() { + let mut slice = []; + slice = slice.push_back(1); + slice = slice.push_back(2); + // Without turbofish a type annotation would be needed on the left hand side + let array = slice.as_array::<2>(); +} +``` + + +```rust +trait MyTrait { + fn ten() -> Self; +} + +impl MyTrait for Field { + fn ten() -> Self { 10 } +} + +struct Foo { + inner: T +} + +impl Foo { + fn generic_method(_self: Self) -> U where U: MyTrait { + U::ten() + } +} + +fn example() { + let foo: Foo = Foo { inner: 1 }; + // Using a type other than `Field` here (e.g. u32) would fail as + // there is no matching impl for `u32: MyTrait`. + // + // Substituting the `10` on the left hand side of this assert + // with `10 as u32` would also fail with a type mismatch as we + // are expecting a `Field` from the right hand side. + assert(10 as u32 == foo.generic_method::()); +} +``` + +## Arithmetic Generics + +In addition to numeric generics, Noir also allows a limited form of arithmetic on generics. +When you have a numeric generic such as `N`, you can use the following operators on it in a +type position: `+`, `-`, `*`, `/`, and `%`. + +Note that type checking arithmetic generics is a best effort guess from the compiler and there +are many cases of types that are equal that the compiler may not see as such. For example, +we know that `T * (N + M)` should be equal to `T*N + T*M` but the compiler does not currently +apply the distributive law and thus sees these as different types. + +Even with this limitation though, the compiler can handle common cases decently well: + +```rust +trait Serialize { + fn serialize(self) -> [Field; N]; +} + +impl Serialize<1> for Field { + fn serialize(self) -> [Field; 1] { + [self] + } +} + +impl Serialize for [T; N] + where T: Serialize { .. } + +impl Serialize for (T, U) + where T: Serialize, U: Serialize { .. } + +fn main() { + let data = (1, [2, 3, 4]); + assert_eq(data.serialize().len(), 4); +} +``` + +Note that if there is any over or underflow the types will fail to unify: + +```rust title="underflow-example" showLineNumbers +fn pop(array: [Field; N]) -> [Field; N - 1] { + let mut result: [Field; N - 1] = std::mem::zeroed(); + for i in 0..N - 1 { + result[i] = array[i]; + } + result +} + +fn main() { + // error: Could not determine array length `(0 - 1)` + pop([]); +} +``` +> Source code: test_programs/compile_failure/arithmetic_generics_underflow/src/main.nr#L1-L14 + + +This also applies if there is underflow in an intermediate calculation: + +```rust title="intermediate-underflow-example" showLineNumbers +fn main() { + // From main it looks like there's nothing sketchy going on + seems_fine([]); +} + +// Since `seems_fine` says it can receive and return any length N +fn seems_fine(array: [Field; N]) -> [Field; N] { + // But inside `seems_fine` we pop from the array which + // requires the length to be greater than zero. + + // error: Could not determine array length `(0 - 1)` + push_zero(pop(array)) +} + +fn pop(array: [Field; N]) -> [Field; N - 1] { + let mut result: [Field; N - 1] = std::mem::zeroed(); + for i in 0..N - 1 { + result[i] = array[i]; + } + result +} + +fn push_zero(array: [Field; N]) -> [Field; N + 1] { + let mut result: [Field; N + 1] = std::mem::zeroed(); + for i in 0..N { + result[i] = array[i]; + } + // index N is already zeroed + result +} +``` +> Source code: test_programs/compile_failure/arithmetic_generics_intermediate_underflow/src/main.nr#L1-L32 + diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.35.0/noir/concepts/globals.md b/noir/noir-repo/docs/versioned_docs/version-v0.35.0/noir/concepts/globals.md new file mode 100644 index 00000000000..1145c55dfc7 --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.35.0/noir/concepts/globals.md @@ -0,0 +1,82 @@ +--- +title: Global Variables +description: + Learn about global variables in Noir.

This is often used for implementing generic types. +For example, here is the implementation for array equality: + +```rust +impl Eq for [T; let N: u32] where T: Eq { + // Test if two arrays have the same elements. + // Because both arrays must have length N, we know their lengths already match. + fn eq(self, other: Self) -> bool { + let mut result = true; + + for i in 0 .. self.len() { + // The T: Eq constraint is needed to call == on the array elements here + result &= self[i] == other[i]; + } + + result + } +} +``` + +Where clauses can also be placed on struct implementations. +For example, here is a method utilizing a generic type that implements the equality trait. + +```rust +struct Foo { + a: u32, + b: T, +} + +impl Foo where T: Eq { + fn eq(self, other: Self) -> bool { + (self.a == other.a) & self.b.eq(other.b) + } +} +``` + +## Generic Traits + +Traits themselves can also be generic by placing the generic arguments after the trait name. These generics are in +scope of every item within the trait. + +```rust +trait Into { + // Convert `self` to type `T` + fn into(self) -> T; +} +``` + +When implementing generic traits the generic arguments of the trait must be specified. This is also true anytime +when referencing a generic trait (e.g. in a `where` clause). + +```rust +struct MyStruct { + array: [Field; 2], +} + +impl Into<[Field; 2]> for MyStruct { + fn into(self) -> [Field; 2] { + self.array + } +} + +fn as_array(x: T) -> [Field; 2] + where T: Into<[Field; 2]> +{ + x.into() +} + +fn main() { + let array = [1, 2]; + let my_struct = MyStruct { array }; + + assert_eq(as_array(my_struct), array); +} +``` + +### Associated Types and Constants + +Traits also support associated types and constraints which can be thought of as additional generics that are referred to by name. + +Here's an example of a trait with an associated type `Foo` and a constant `Bar`: + +```rust +trait MyTrait { + type Foo; + + let Bar: u32; +} +``` + +Now when we're implementing `MyTrait` we also have to provide values for `Foo` and `Bar`: + +```rust +impl MyTrait for Field { + type Foo = i32; + + let Bar: u32 = 11; +} +``` + +Since associated constants can also be used in a type position, its values are limited to only other +expression kinds allowed in numeric generics. + +Note that currently all associated types and constants must be explicitly specified in a trait constraint. +If we leave out any, we'll get an error that we're missing one: + +```rust +// Error! Constraint is missing associated constant for `Bar` +fn foo(x: T) where T: MyTrait { + ... +} +``` + +Because all associated types and constants must be explicitly specified, they are essentially named generics, +although this is set to change in the future. Future versions of Noir will allow users to elide associated types +in trait constraints similar to Rust. When this is done, you may still refer to their value with the `::AssociatedType` +syntax: + +```rust +// Only valid in future versions of Noir: +fn foo(x: T) where T: MyTrait { + let _: ::Foo = ...; +} +``` + +The type as trait syntax is possible in Noir today but is less useful when each type must be explicitly specified anyway: + +```rust +fn foo(x: T) where T: MyTrait { + // Works, but could just use F directly + let _: >::Foo = ...; + + let _: F = ...; +} +``` + +## Trait Methods With No `self` + +A trait can contain any number of methods, each of which have access to the `Self` type which represents each type +that eventually implements the trait. Similarly, the `self` variable is available as well but is not required to be used. +For example, we can define a trait to create a default value for a type. This trait will need to return the `Self` type +but doesn't need to take any parameters: + +```rust +trait Default { + fn default() -> Self; +} +``` + +Implementing this trait can be done similarly to any other trait: + +```rust +impl Default for Field { + fn default() -> Field { + 0 + } +} + +struct MyType {} + +impl Default for MyType { + fn default() -> Field { + MyType {} + } +} +``` + +However, since there is no `self` parameter, we cannot call it via the method call syntax `object.method()`. +Instead, we'll need to refer to the function directly. This can be done either by referring to the +specific impl `MyType::default()` or referring to the trait itself `Default::default()`. In the later +case, type inference determines the impl that is selected. + +```rust +let my_struct = MyStruct::default(); + +let x: Field = Default::default(); +let result = x + Default::default(); +``` + +:::warning + +```rust +let _ = Default::default(); +``` + +If type inference cannot select which impl to use because of an ambiguous `Self` type, an impl will be +arbitrarily selected. This occurs most often when the result of a trait function call with no parameters +is unused. To avoid this, when calling a trait function with no `self` or `Self` parameters or return type, +always refer to it via the implementation type's namespace - e.g. `MyType::default()`. +This is set to change to an error in future Noir versions. + +::: + +## Default Method Implementations + +A trait can also have default implementations of its methods by giving a body to the desired functions. +Note that this body must be valid for all types that may implement the trait. As a result, the only +valid operations on `self` will be operations valid for any type or other operations on the trait itself. + +```rust +trait Numeric { + fn add(self, other: Self) -> Self; + + // Default implementation of double is (self + self) + fn double(self) -> Self { + self.add(self) + } +} +``` + +When implementing a trait with default functions, a type may choose to implement only the required functions: + +```rust +impl Numeric for Field { + fn add(self, other: Field) -> Field { + self + other + } +} +``` + +Or it may implement the optional methods as well: + +```rust +impl Numeric for u32 { + fn add(self, other: u32) -> u32 { + self + other + } + + fn double(self) -> u32 { + self * 2 + } +} +``` + +## Impl Specialization + +When implementing traits for a generic type it is possible to implement the trait for only a certain combination +of generics. This can be either as an optimization or because those specific generics are required to implement the trait. + +```rust +trait Sub { + fn sub(self, other: Self) -> Self; +} + +struct NonZero { + value: T, +} + +impl Sub for NonZero { + fn sub(self, other: Self) -> Self { + let value = self.value - other.value; + assert(value != 0); + NonZero { value } + } +} +``` + +## Overlapping Implementations + +Overlapping implementations are disallowed by Noir to ensure Noir's decision on which impl to select is never ambiguous. +This means if a trait `Foo` is already implemented +by a type `Bar` for all `T`, then we cannot also have a separate impl for `Bar` (or any other +type argument). Similarly, if there is an impl for all `T` such as `impl Debug for T`, we cannot create +any more impls to `Debug` for other types since it would be ambiguous which impl to choose for any given +method call. + +```rust +trait Trait {} + +// Previous impl defined here +impl Trait for (A, B) {} + +// error: Impl for type `(Field, Field)` overlaps with existing impl +impl Trait for (Field, Field) {} +``` + +## Trait Coherence + +Another restriction on trait implementations is coherence. This restriction ensures other crates cannot create +impls that may overlap with other impls, even if several unrelated crates are used as dependencies in the same +program. + +The coherence restriction is: to implement a trait, either the trait itself or the object type must be declared +in the crate the impl is in. + +In practice this often comes up when using types provided by libraries. If a library provides a type `Foo` that does +not implement a trait in the standard library such as `Default`, you may not `impl Default for Foo` in your own crate. +While restrictive, this prevents later issues or silent changes in the program if the `Foo` library later added its +own impl for `Default`. If you are a user of the `Foo` library in this scenario and need a trait not implemented by the +library your choices are to either submit a patch to the library or use the newtype pattern. + +### The Newtype Pattern + +The newtype pattern gets around the coherence restriction by creating a new wrapper type around the library type +that we cannot create `impl`s for. Since the new wrapper type is defined in our current crate, we can create +impls for any trait we need on it. + +```rust +struct Wrapper { + foo: some_library::Foo, +} + +impl Default for Wrapper { + fn default() -> Wrapper { + Wrapper { + foo: some_library::Foo::new(), + } + } +} +``` + +Since we have an impl for our own type, the behavior of this code will not change even if `some_library` is updated +to provide its own `impl Default for Foo`. The downside of this pattern is that it requires extra wrapping and +unwrapping of values when converting to and from the `Wrapper` and `Foo` types. + +### Visibility + +By default, like functions, traits are private to the module the exist in. You can use `pub` +to make the trait public or `pub(crate)` to make it public to just its crate: + +```rust +// This trait is now public +pub trait Trait {} +``` \ No newline at end of file diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.35.0/noir/concepts/unconstrained.md b/noir/noir-repo/docs/versioned_docs/version-v0.35.0/noir/concepts/unconstrained.md new file mode 100644 index 00000000000..b5221b8d2dd --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.35.0/noir/concepts/unconstrained.md @@ -0,0 +1,104 @@ +--- +title: Unconstrained Functions +description: "Learn about what unconstrained functions in Noir are, how to use them and when you'd want to." + +keywords: [Noir programming language, unconstrained, open] +sidebar_position: 5 +--- + +Unconstrained functions are functions which do not constrain any of the included computation and allow for non-deterministic computation. + +## Why? + +Zero-knowledge (ZK) domain-specific languages (DSL) enable developers to generate ZK proofs from their programs by compiling code down to the constraints of an NP complete language (such as R1CS or PLONKish languages).

Thus, it is necessary that when we switch from performing some operation directly inside of a circuit to inside of an unconstrained environment that the appropriate constraints are still laid down elsewhere in the circuit. + +## Example + +An in depth example might help drive the point home. This example comes from the excellent [post](https://discord.com/channels/1113924620781883405/1124022445054111926/1128747641853972590) by Tom in the Noir Discord. + +Let's look at how we can optimize a function to turn a `u72` into an array of `u8`s. + +```rust +fn main(num: u72) -> pub [u8; 8] { + let mut out: [u8; 8] = [0; 8]; + for i in 0..8 { + out[i] = (num >> (56 - (i * 8)) as u72 & 0xff) as u8; + } + + out +} +``` + +``` +Total ACIR opcodes generated for language PLONKCSat { width: 3 }: 91 +Backend circuit size: 3619 +``` + +A lot of the operations in this function are optimized away by the compiler (all the bit-shifts turn into divisions by constants). However we can save a bunch of gates by casting to u8 a bit earlier. This automatically truncates the bit-shifted value to fit in a u8 which allows us to remove the AND against 0xff. This saves us ~480 gates in total. + +```rust +fn main(num: u72) -> pub [u8; 8] { + let mut out: [u8; 8] = [0; 8]; + for i in 0..8 { + out[i] = (num >> (56 - (i * 8)) as u8; + } + + out +} +``` + +``` +Total ACIR opcodes generated for language PLONKCSat { width: 3 }: 75 +Backend circuit size: 3143 +``` + +Those are some nice savings already but we can do better. This code is all constrained so we're proving every step of calculating out using num, but we don't actually care about how we calculate this, just that it's correct. This is where brillig comes in. + +It turns out that truncating a u72 into a u8 is hard to do inside a snark, each time we do as u8 we lay down 4 ACIR opcodes which get converted into multiple gates. It's actually much easier to calculate num from out than the other way around. All we need to do is multiply each element of out by a constant and add them all together, both relatively easy operations inside a snark. + +We can then run `u72_to_u8` as unconstrained brillig code in order to calculate out, then use that result in our constrained function and assert that if we were to do the reverse calculation we'd get back num. This looks a little like the below: + +```rust +fn main(num: u72) -> pub [u8; 8] { + let out = unsafe { + u72_to_u8(num) + }; + + let mut reconstructed_num: u72 = 0; + for i in 0..8 { + reconstructed_num += (out[i] as u72 << (56 - (8 * i))); + } + assert(num == reconstructed_num); + out +} + +unconstrained fn u72_to_u8(num: u72) -> [u8; 8] { + let mut out: [u8; 8] = [0; 8]; + for i in 0..8 { + out[i] = (num >> (56 - (i * 8))) as u8; + } + out +} +``` + +``` +Total ACIR opcodes generated for language PLONKCSat { width: 3 }: 78 +Backend circuit size: 2902 +``` + +This ends up taking off another ~250 gates from our circuit! We've ended up with more ACIR opcodes than before but they're easier for the backend to prove (resulting in fewer gates). + +Note that in order to invoke unconstrained functions we need to wrap them in an `unsafe` block, +to make it clear that the call is unconstrained. + +Generally we want to use brillig whenever there's something that's easy to verify but hard to compute within the circuit. For example, if you wanted to calculate a square root of a number it'll be a much better idea to calculate this in brillig and then assert that if you square the result you get back your number. + +## Break and Continue + +In addition to loops over runtime bounds, `break` and `continue` are also available in unconstrained code.

This is due to every input in a test being a constant rather than a witness, so we issue an error during compilation while we only print during execution (which comes after compilation). Neither `println`, nor `print` are callable for failed constraints caught at compile time. + +Both `print` and `println` are generic functions which can work on integers, fields, strings, and even structs or expressions. Note however, that slices are currently unsupported. For example: + +```rust +struct Person { + age: Field, + height: Field, +} + +fn main(age: Field, height: Field) { + let person = Person { + age: age, + height: height, + }; + println(person); + println(age + height); + println("Hello world!"); +} +``` + +You can print different types in the same statement (including strings) with a type called `fmtstr`. It can be specified in the same way as a normal string, just prepended with an "f" character: + +```rust + let fmt_str = f"i: {i}, j: {j}"; + println(fmt_str); + + let s = myStruct { y: x, x: y }; + println(s); + + println(f"i: {i}, s: {s}"); + + println(x); + println([x, y]); + + let foo = fooStruct { my_struct: s, foo: 15 }; + println(f"s: {s}, foo: {foo}"); + + println(15); // prints 0x0f, implicit Field + println(-1 as u8); // prints 255 + println(-1 as i8); // prints -1 +``` + +Examples shown above are interchangeable between the two `print` statements: + +```rust +let person = Person { age : age, height : height }; + +println(person); +print(person); + +println("Hello world!"); // Prints with a newline at the end of the input +print("Hello world!"); // Prints the input and keeps cursor on the same line +``` diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.35.0/noir/standard_library/merkle_trees.md b/noir/noir-repo/docs/versioned_docs/version-v0.35.0/noir/standard_library/merkle_trees.md new file mode 100644 index 00000000000..6a9ebf72ada --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.35.0/noir/standard_library/merkle_trees.md @@ -0,0 +1,58 @@ +--- +title: Merkle Trees +description: Learn about Merkle Trees in Noir with this tutorial.

For example, `u32: From` can losslessly convert any `u16` into a valid `u32` such that the original `u16` can be recovered. On the other hand, `u16: From` should not be implemented as `2**16` is a `u32` which cannot be losslessly converted into a `u16`. +- The conversion is *value-preserving*: the conceptual kind and meaning of the resulting value is the same, even though the Noir type and technical representation might be different. While it's possible to infallibly and losslessly convert a `u8` into a `str<2>` hex representation, `4u8` and `"04"` are too different for `str<2>: From` to be implemented. +- The conversion is *obvious*: it's the only reasonable conversion between the two types. If there's ambiguity on how to convert between them such that the same input could potentially map to two different values then a named method should be used. For instance rather than implementing `U128: From<[u8; 16]>`, the methods `U128::from_le_bytes` and `U128::from_be_bytes` are used as otherwise the endianness of the array would be ambiguous, resulting in two potential values of `U128` from the same byte array. + +One additional recommendation specific to Noir is: +- The conversion is *efficient*: it's relatively cheap to convert between the two types. Due to being a ZK DSL, it's more important to avoid unnecessary computation compared to Rust. If the implementation of `From` would encourage users to perform unnecessary conversion, resulting in additional proving time, then it may be preferable to expose functionality such that this conversion may be avoided. + +### `std::convert::Into` + +The `Into` trait is defined as the reciprocal of `From`. It should be easy to convince yourself that if we can convert to type `A` from type `B`, then it's possible to convert type `B` into type `A`. + +For this reason, implementing `From` on a type will automatically generate a matching `Into` implementation. One should always prefer implementing `From` over `Into` as implementing `Into` will not generate a matching `From` implementation. + +```rust title="into-trait" showLineNumbers +pub trait Into { + fn into(self) -> T; +} + +impl Into for U where T: From { + fn into(self) -> T { + T::from(self) + } +} +``` +> Source code: noir_stdlib/src/convert.nr#L13-L23 + + +`Into` is most useful when passing function arguments where the types don't quite match up with what the function expects. In this case, the compiler has enough type information to perform the necessary conversion by just appending `.into()` onto the arguments in question. + +--- + +## `std::cmp` + +### `std::cmp::Eq` + +```rust title="eq-trait" showLineNumbers +pub trait Eq { + fn eq(self, other: Self) -> bool; +} +``` +> Source code: noir_stdlib/src/cmp.nr#L4-L8 + + +Returns `true` if `self` is equal to `other`.

Paste the following to set the stage: + +```javascript +import { defineConfig } from 'vite'; +import copy from 'rollup-plugin-copy'; +import fs from 'fs'; +import path from 'path'; + +const wasmContentTypePlugin = { + name: 'wasm-content-type-plugin', + configureServer(server) { + server.middlewares.use(async (req, res, next) => { + if (req.url.endsWith('.wasm')) { + res.setHeader('Content-Type', 'application/wasm'); + const newPath = req.url.replace('deps', 'dist'); + const targetPath = path.join(__dirname, newPath); + const wasmContent = fs.readFileSync(targetPath); + return res.end(wasmContent); + } + next(); + }); + }, +}; + +export default defineConfig(({ command }) => { + if (command === 'serve') { + return { + build: { + target: 'esnext', + rollupOptions: { + external: ['@aztec/bb.js'] + } + }, + optimizeDeps: { + esbuildOptions: { + target: 'esnext' + } + }, + plugins: [ + copy({ + targets: [{ src: 'node_modules/**/*.wasm', dest: 'node_modules/.vite/dist' }], + copySync: true, + hook: 'buildStart', + }), + command === 'serve' ? wasmContentTypePlugin : [], + ], + }; + } + + return {}; +}); +``` + +#### Install Dependencies + +Now that our stage is set, install the necessary NoirJS packages along with our other dependencies: + +```bash +npm install && npm install @noir-lang/backend_barretenberg@0.31.0 @noir-lang/noir_js@0.31.0 +npm install rollup-plugin-copy --save-dev +``` + +:::info + +At this point in the tutorial, your folder structure should look like this: + +```tree +. +└── circuit + └── ...etc... +└── vite-project <---- our working directory + └── ...etc... +``` + +::: + +#### Some cleanup + +`npx create vite` is amazing but it creates a bunch of files we don't really need for our simple example. Actually, let's just delete everything except for `vite.config.js`, `index.html`, `main.js` and `package.json`. I feel lighter already. + +![my heart is ready for you, noir.js](@site/static/img/memes/titanic.jpeg) + +## HTML + +Our app won't run like this, of course. We need some working HTML, at least. Let's open our broken-hearted `index.html` and replace everything with this code snippet: + +```html + + + + + + +

+
+ + +``` + +It _could_ be a beautiful UI... Depending on which universe you live in. + +## Some good old vanilla Javascript + +Our love for Noir needs undivided attention, so let's just open `main.js` and delete everything (this is where the romantic scenery becomes a bit creepy). + +Start by pasting in this boilerplate code: + +```js +function display(container, msg) { + const c = document.getElementById(container); + const p = document.createElement('p'); + p.textContent = msg; + c.appendChild(p); +} + +document.getElementById('submitGuess').addEventListener('click', async () => { + try { + // here's where love happens + } catch (err) { + display('logs', 'Oh 💔 Wrong guess'); + } +}); +``` + +The display function doesn't do much. We're simply manipulating our website to see stuff happening. For example, if the proof fails, it will simply log a broken heart 😢 + +:::info + +At this point in the tutorial, your folder structure should look like this: + +```tree +. +└── circuit + └── ...same as above +└── vite-project + ├── vite.config.js + ├── main.js + ├── package.json + └── index.html +``` + +You'll see other files and folders showing up (like `package-lock.json`, `node_modules`) but you shouldn't have to care about those. + +::: + +## Some NoirJS + +We're starting with the good stuff now. If you've compiled the circuit as described above, you should have a `json` file we want to import at the very top of our `main.js` file: + +```ts +import circuit from '../circuit/target/circuit.json'; +``` + +[Noir is backend-agnostic](../index.mdx#whats-new-about-noir). We write Noir, but we also need a proving backend. That's why we need to import and instantiate the two dependencies we installed above: `BarretenbergBackend` and `Noir`. Let's import them right below: + +```js +import { BarretenbergBackend, BarretenbergVerifier as Verifier } from '@noir-lang/backend_barretenberg'; +import { Noir } from '@noir-lang/noir_js'; +``` + +And instantiate them inside our try-catch block: + +```ts +// try { +const backend = new BarretenbergBackend(circuit); +const noir = new Noir(circuit); +// } +``` + +:::note + +For the remainder of the tutorial, everything will be happening inside the `try` block + +::: + +## Our app + +Now for the app itself. We're capturing whatever is in the input when people press the submit button. Just add this: + +```js +const x = parseInt(document.getElementById('guessInput').value); +const input = { x, y: 2 }; +``` + +Now we're ready to prove stuff! Let's feed some inputs to our circuit and calculate the proof: + +```js +await setup(); // let's squeeze our wasm inits here + +display('logs', 'Generating proof... ⌛'); +const { witness } = await noir.execute(input); +const proof = await backend.generateProof(witness); +display('logs', 'Generating proof... ✅'); +display('results', proof.proof); +``` + +You're probably eager to see stuff happening, so go and run your app now! + +From your terminal, run `npm run dev`. If it doesn't open a browser for you, just visit `localhost:5173`. You should now see the worst UI ever, with an ugly input. + +![Getting Started 0](@site/static/img/noir_getting_started_1.png) + +Now, our circuit says `fn main(x: Field, y: pub Field)`. This means only the `y` value is public, and it's hardcoded above: `input = { x, y: 2 }`. In other words, you won't need to send your secret`x` to the verifier! + +By inputting any number other than 2 in the input box and clicking "submit", you should get a valid proof. Otherwise the proof won't even generate correctly. By the way, if you're human, you shouldn't be able to understand anything on the "proof" box. That's OK. We like you, human ❤️. + +## Verifying + +Time to celebrate, yes! But we shouldn't trust machines so blindly. Let's add these lines to see our proof being verified: + +```js +display('logs', 'Verifying proof... ⌛'); +const isValid = await backend.verifyProof(proof); + +// or to cache and use the verification key: +// const verificationKey = await backend.getVerificationKey(); +// const verifier = new Verifier(); +// const isValid = await verifier.verifyProof(proof, verificationKey); + +if (isValid) display('logs', 'Verifying proof... ✅'); +``` + +You have successfully generated a client-side Noir web app! + +![coded app without math knowledge](@site/static/img/memes/flextape.jpeg) + +## Further Reading + +You can see how noirjs is used in a full stack Next.js hardhat application in the [noir-starter repo here](https://github.com/noir-lang/noir-starter/tree/main/vite-hardhat). The example shows how to calculate a proof in the browser and verify it with a deployed Solidity verifier contract from noirjs. + +You should also check out the more advanced examples in the [noir-examples repo](https://github.com/noir-lang/noir-examples), where you'll find reference usage for some cool apps. + +## UltraHonk Backend + +Barretenberg has recently exposed a new UltraHonk backend. We can use UltraHonk in NoirJS after version 0.33.0. Everything will be the same as the tutorial above, except that the class we need to import will change: +```js +import { UltraHonkBackend, UltraHonkVerifier as Verifier } from '@noir-lang/backend_barretenberg'; +``` +The backend will then be instantiated as such: +```js +const backend = new UltraHonkBackend(circuit); +``` +Then all the commands to prove and verify your circuit will be same. + +The only feature currently unsupported with UltraHonk are [recursive proofs](../explainers/explainer-recursion.md). \ No newline at end of file diff --git a/noir/noir-repo/docs/versioned_sidebars/version-v0.35.0-sidebars.json b/noir/noir-repo/docs/versioned_sidebars/version-v0.35.0-sidebars.json new file mode 100644 index 00000000000..b9ad026f69f --- /dev/null +++ b/noir/noir-repo/docs/versioned_sidebars/version-v0.35.0-sidebars.json @@ -0,0 +1,93 @@ +{ + "sidebar": [ + { + "type": "doc", + "id": "index" + }, + { + "type": "category", + "label": "Getting Started", + "items": [ + { + "type": "autogenerated", + "dirName": "getting_started" + } + ] + }, + { + "type": "category", + "label": "The Noir Language", + "items": [ + { + "type": "autogenerated", + "dirName": "noir" + } + ] + }, + { + "type": "html", + "value": "
