You can pass certain inputs to it, and it will generate a deterministic output for those inputs. But what if you wanted to defer some calculation to an outside process or source? + +Oracles are functions that provide this feature. + +## Use cases + +An example usage for Oracles is proving something on-chain. For example, proving that the ETH-USDC quote was below a certain target at a certain block time. Or even making more complex proofs like proving the ownership of an NFT as an anonymous login method. + +Another interesting use case is to defer expensive calculations to be made outside of the Noir program, and then constraining the result; similar to the use of [unconstrained functions](../noir/concepts//unconstrained.md). + +In short, anything that can be constrained in a Noir program but needs to be fetched from an external source is a great candidate to be used in oracles. + +## Constraining oracles + +Just like in The Matrix, Oracles are powerful. But with great power, comes great responsibility. Just because you're using them in a Noir program doesn't mean they're true. Noir has no superpowers.

A classic example would be the calculation of the factorial of a number: + +```js +function factorial(n) { + if (n === 0 || n === 1) { + return 1; + } else { + return n * factorial(n - 1); + } +} +``` + +In this case, while `n` is not `1`, this function will keep calling itself until it hits the base case, bubbling up the result on the call stack: + +```md + Is `n` 1? <--------- + /\ / + / \ n = n -1 + / \ / + Yes No -------- +``` + +In Zero-Knowledge, recursion has some similarities. + +It is not a Noir function calling itself, but a proof being used as an input to another circuit. 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.md), 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. So you are able to cache the verification key and reuse it later. + +Currently, Noir JS packages don't expose the functionality of loading proving and verification keys, but that feature exists in the underlying `bb.js` package. + +## How can I try it + +Learn more about using recursion in Nargo and NoirJS in the [how-to guide](../how_to/how-to-recursion.md) and see a full example in [noir-examples](https://github.com/noir-lang/noir-examples). diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.28.0/getting_started/_category_.json b/noir/noir-repo/docs/versioned_docs/version-v0.28.0/getting_started/_category_.json new file mode 100644 index 00000000000..5d694210bbf --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.28.0/getting_started/_category_.json @@ -0,0 +1,5 @@ +{ + "position": 0, + "collapsible": true, + "collapsed": true +} diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.28.0/getting_started/hello_noir/_category_.json b/noir/noir-repo/docs/versioned_docs/version-v0.28.0/getting_started/hello_noir/_category_.json new file mode 100644 index 00000000000..23b560f610b --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.28.0/getting_started/hello_noir/_category_.json @@ -0,0 +1,5 @@ +{ + "position": 1, + "collapsible": true, + "collapsed": true +} diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.28.0/getting_started/hello_noir/index.md b/noir/noir-repo/docs/versioned_docs/version-v0.28.0/getting_started/hello_noir/index.md new file mode 100644 index 00000000000..743c4d8d634 --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.28.0/getting_started/hello_noir/index.md @@ -0,0 +1,142 @@ +--- +title: Creating a Project +description: + Learn how to create and verify your first Noir program using Nargo, a programming language for + zero-knowledge proofs. +keywords: + [ + Nargo, + Noir, + zero-knowledge proofs, + programming language, + create Noir program, + verify Noir program, + step-by-step guide, + ] +sidebar_position: 1 + +--- + +Now that we have installed Nargo, it is time to make our first hello world program! + +## Create a Project Directory + +Noir code can live anywhere on your computer.

For example: + +```toml +[workspace] +members = ["crates/a", "crates/b"] +default-member = "crates/a" +``` + +#### Package section + +The package section defines a number of fields including: + +- `name` (**required**) - the name of the package +- `type` (**required**) - can be "bin", "lib", or "contract" to specify whether its a binary, library or Aztec contract +- `authors` (optional) - authors of the project +- `compiler_version` - specifies the version of the compiler to use. This is enforced by the compiler and follow's [Rust's versioning](https://doc.rust-lang.org/cargo/reference/manifest.html#the-version-field), so a `compiler_version = 0.18.0` will enforce Nargo version 0.18.0, `compiler_version = ^0.18.0` will enforce anything above 0.18.0 but below 0.19.0, etc. For more information, see how [Rust handles these operators](https://docs.rs/semver/latest/semver/enum.Op.html) +- `description` (optional) +- `entry` (optional) - a relative filepath to use as the entry point into your package (overrides the default of `src/lib.nr` or `src/main.nr`) +- `backend` (optional) +- `license` (optional) + +#### Dependencies section + +This is where you will specify any dependencies for your project.

Since neither `x` nor `y` is marked as public, the verifier does not supply any inputs, when +verifying the proof. + +The prover supplies the values for `x` and `y` in the _Prover.toml_ file. + +As for the program body, `assert` ensures that the condition to be satisfied (e.g. `x != y`) is +constrained by the proof of the execution of said program (i.e. if the condition was not met, the +verifier would reject the proof as an invalid proof). + +### Prover.toml + +The _Prover.toml_ file is a file which the prover uses to supply his witness values(both private and +public). + +In our hello world program the _Prover.toml_ file looks like this: + +```toml +x = "1" +y = "2" +``` + +When the command `nargo prove` is executed, two processes happen: + +1. Noir creates a proof that `x`, which holds the value of `1`, and `y`, which holds the value of `2`, + is not equal. This inequality constraint is due to the line `assert(x != y)`. + +2. Noir creates and stores the proof of this statement in the _proofs_ directory in a file called your-project.proof. So if your project is named "private_voting" (defined in the project Nargo.toml), the proof will be saved at `./proofs/private_voting.proof`. Opening this file will display the proof in hex format. + +#### Arrays of Structs + +The following code shows how to pass an array of structs to a Noir program to generate a proof. + +```rust +// main.nr +struct Foo { + bar: Field, + baz: Field, +} + +fn main(foos: [Foo; 3]) -> pub Field { + foos[2].bar + foos[2].baz +} +``` + +Prover.toml: + +```toml +[[foos]] # foos[0] +bar = 0 +baz = 0 + +[[foos]] # foos[1] +bar = 0 +baz = 0 + +[[foos]] # foos[2] +bar = 1 +baz = 2 +``` + +#### Custom toml files + +You can specify a `toml` file with a different name to use for proving by using the `--prover-name` or `-p` flags. + +This command looks for proof inputs in the default **Prover.toml** and generates the proof and saves it at `./proofs/.proof`: + +```bash +nargo prove +``` + +This command looks for proof inputs in the custom **OtherProver.toml** and generates proof and saves it at `./proofs/.proof`: + +```bash +nargo prove -p OtherProver +``` + +## Verifying a Proof + +When the command `nargo verify` is executed, two processes happen: + +1. Noir checks in the _proofs_ directory for a proof file with the project name (eg. test_project.proof) + +2. If that file is found, the proof's validity is checked + +> **Note:** The validity of the proof is linked to the current Noir program; if the program is +> changed and the verifier verifies the proof, it will fail because the proof is not valid for the +> _modified_ Noir program. + +In production, the prover and the verifier are usually two separate entities.

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 a 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("getSqrt", async (params) => { + const values = params[0].Array.map((field) => { + return `${Math.sqrt(parseInt(field, 16))}`; + }); + return { values: [{ Array: values }] }; +}); +``` + +:::tip + +Brillig expects an object with an array of values. Each value is an object declaring to be `Single` or `Array` and returning a field element *as a string*. For example: + +```json +{ "values": [{ "Array": ["1", "2"] }]} +{ "values": [{ "Single": "1" }]} +{ "values": [{ "Single": "1" }, { "Array": ["1", "2"] }]} +``` + +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[], +} +``` + +::: + +## Step 3 - Usage with Nargo + +Using the [`nargo` CLI tool](../getting_started/installation/index.md), you can use oracles in the `nargo test`, `nargo execute` and `nargo prove` 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`.

However, the guide should work just the same if you're using `noir_wasm`. + +:::info + +As you've read in the [explainer](../explainers/explainer-recursion.md), a recursive proof is an intermediate proof. This means that it doesn't necessarily generate the final step that makes it verifiable in a smart contract. However, it is easy to verify within another circuit. + +While "standard" usage of NoirJS packages abstracts final proofs, it currently lacks the necessary interface to abstract away intermediate proofs.

For the purpose of this guide, we will assume the following: + +- `main`: a circuit of type `assert(x != y)`, where `main` is marked with a `#[recursive]` attribute. This attribute states that the backend should generate proofs that are friendly for verification within another circuit. +- `recursive`: a circuit that verifies `main` + +For a full example on how recursive proofs work, please refer to the [noir-examples](https://github.com/noir-lang/noir-examples) repository. 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, backend) +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. In fact, if you're using recursive proofs, you're probably interested of using them this way! + +:::tip + +Managing circuits and "who does what" can be confusing. To make sure your naming is consistent, you can keep them in an object. For example: + +```js +const circuits = { + main: mainJSON, + recursive: recursiveJSON +} +const backends = { + main: new BarretenbergBackend(circuits.main), + recursive: new BarretenbergBackend(circuits.recursive) +} +const noir_programs = { + main: new Noir(circuits.main, backends.main), + recursive: new Noir(circuits.recursive, backends.recursive) +} +``` + +This allows you to neatly call exactly the method you want without conflicting names: + +```js +// Alice runs this 👇 +const { witness: mainWitness } = await noir_programs.main.execute(input) +const proof = await backends.main.generateProof(mainWitness) + +// Bob runs this 👇 +const verified = await backends.main.verifyProof(proof) +const { proofAsFields, vkAsFields, vkHash } = await backends.main.generateRecursiveProofArtifacts( + proof, + numPublicInputs, +); +const recursiveProof = await noir_programs.recursive.generateProof(recursiveInputs) +``` + +::: diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.28.0/how_to/how-to-solidity-verifier.md b/noir/noir-repo/docs/versioned_docs/version-v0.28.0/how_to/how-to-solidity-verifier.md new file mode 100644 index 00000000000..e3c7c1065da --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.28.0/how_to/how-to-solidity-verifier.md @@ -0,0 +1,231 @@ +--- +title: Generate a Solidity Verifier +description: + Learn how to run the verifier as a smart contract on the blockchain.

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.

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 read 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 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. For `_proof`, run `nargo prove` and use the string in `proof/.proof` (adding the hex `0x` prefix). We can also copy the public input from `Verifier.toml`, as it will be properly formatted as 32-byte strings: + +``` +0x...... , [0x0000.....02] +``` + +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. Like before, these values are populated in Verifier.toml after running `nargo prove`. + +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 + +ZK-SNARK verification depends on some precompiled cryptographic primitives such as Elliptic Curve Pairings (if you like complex math, you can read about EC Pairings [here](https://medium.com/@VitalikButerin/exploring-elliptic-curve-pairings-c73c1864e627)). 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. + +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 + +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!

Each trait defines +the interface of several methods contained within the trait. Types can then implement this trait by providing +implementations for these methods. For example in the program: + +```rust +struct Rectangle { + width: Field, + height: Field, +} + +impl Rectangle { + fn area(self) -> Field { + self.width * self.height + } +} + +fn log_area(r: Rectangle) { + println(r.area()); +} +``` + +We have a function `log_area` to log the area of a `Rectangle`. Now how should we change the program if we want this +function to work on `Triangle`s as well?: + +```rust +struct Triangle { + width: Field, + height: Field, +} + +impl Triangle { + fn area(self) -> Field { + self.width * self.height / 2 + } +} +``` + +Making `log_area` generic over all types `T` would be invalid since not all types have an `area` method. Instead, we can +introduce a new `Area` trait and make `log_area` generic over all types `T` that implement `Area`: + +```rust +trait Area { + fn area(self) -> Field; +} + +fn log_area(shape: T) where T: Area { + println(shape.area()); +} +``` + +We also need to explicitly implement `Area` for `Rectangle` and `Triangle`. We can do that by changing their existing +impls slightly. Note that the parameter types and return type of each of our `area` methods must match those defined +by the `Area` trait. + +```rust +impl Area for Rectangle { + fn area(self) -> Field { + self.width * self.height + } +} + +impl Area for Triangle { + fn area(self) -> Field { + self.width * self.height / 2 + } +} +``` + +Now we have a working program that is generic over any type of Shape that is used! Others can even use this program +as a library with their own types - such as `Circle` - as long as they also implement `Area` for these types. + +## Where Clauses + +As seen in `log_area` above, when we want to create a function or method that is generic over any type that implements +a trait, we can add a where clause to the generic function. + +```rust +fn log_area(shape: T) where T: Area { + println(shape.area()); +} +``` + +It is also possible to apply multiple trait constraints on the same variable at once by combining traits with the `+` +operator. Similarly, we can have multiple trait constraints by separating each with a comma: + +```rust +fn foo(elements: [T], thing: U) where + T: Default + Add + Eq, + U: Bar, +{ + let mut sum = T::default(); + + for element in elements { + sum += element; + } + + if sum == T::default() { + thing.bar(); + } +} +``` + +## Generic Implementations + +You can add generics to a trait implementation by adding the generic list after the `impl` keyword: + +```rust +trait Second { + fn second(self) -> Field; +} + +impl Second for (T, Field) { + fn second(self) -> Field { + self.1 + } +} +``` + +You can also implement a trait for every type this way: + +```rust +trait Debug { + fn debug(self); +} + +impl Debug for T { + fn debug(self) { + println(self); + } +} + +fn main() { + 1.debug(); +} +``` + +### Generic Trait Implementations With Where Clauses + +Where clauses can also be placed on trait implementations themselves to restrict generics in a similar way. +For example, while `impl Foo for T` implements the trait `Foo` for every type, `impl Foo for T where T: Bar` +will implement `Foo` only for types that also implement `Bar`. This is often used for implementing generic types. +For example, here is the implementation for array equality: + +```rust +impl Eq for [T; N] 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 + } +} +``` + +## 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); +} +``` + +## 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: dep::some_library::Foo, +} + +impl Default for Wrapper { + fn default() -> Wrapper { + Wrapper { + foo: dep::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. diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.28.0/noir/concepts/unconstrained.md b/noir/noir-repo/docs/versioned_docs/version-v0.28.0/noir/concepts/unconstrained.md new file mode 100644 index 00000000000..b8e71fe65f0 --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.28.0/noir/concepts/unconstrained.md @@ -0,0 +1,99 @@ +--- +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).

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 = 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). + +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.

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 +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 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.md), 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. So you are able to cache the verification key and reuse it later. + +Currently, Noir JS packages don't expose the functionality of loading proving and verification keys, but that feature exists in the underlying `bb.js` package. + +## How can I try it + +Learn more about using recursion in Nargo and NoirJS in the [how-to guide](../how_to/how-to-recursion.md) and see a full example in [noir-examples](https://github.com/noir-lang/noir-examples). diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.29.0/getting_started/_category_.json b/noir/noir-repo/docs/versioned_docs/version-v0.29.0/getting_started/_category_.json new file mode 100644 index 00000000000..5d694210bbf --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.29.0/getting_started/_category_.json @@ -0,0 +1,5 @@ +{ + "position": 0, + "collapsible": true, + "collapsed": true +} diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.29.0/getting_started/hello_noir/_category_.json b/noir/noir-repo/docs/versioned_docs/version-v0.29.0/getting_started/hello_noir/_category_.json new file mode 100644 index 00000000000..23b560f610b --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.29.0/getting_started/hello_noir/_category_.json @@ -0,0 +1,5 @@ +{ + "position": 1, + "collapsible": true, + "collapsed": true +} diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.29.0/getting_started/hello_noir/index.md b/noir/noir-repo/docs/versioned_docs/version-v0.29.0/getting_started/hello_noir/index.md new file mode 100644 index 00000000000..743c4d8d634 --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.29.0/getting_started/hello_noir/index.md @@ -0,0 +1,142 @@ +--- +title: Creating a Project +description: + Learn how to create and verify your first Noir program using Nargo, a programming language for + zero-knowledge proofs. +keywords: + [ + Nargo, + Noir, + zero-knowledge proofs, + programming language, + create Noir program, + verify Noir program, + step-by-step guide, + ] +sidebar_position: 1 + +--- + +Now that we have installed Nargo, it is time to make our first hello world program! + +## Create a Project Directory + +Noir code can live anywhere on your computer.

Since neither `x` nor `y` is marked as public, the verifier does not supply any inputs, when +verifying the proof. + +The prover supplies the values for `x` and `y` in the _Prover.toml_ file. + +As for the program body, `assert` ensures that the condition to be satisfied (e.g. `x != y`) is +constrained by the proof of the execution of said program (i.e. if the condition was not met, the +verifier would reject the proof as an invalid proof). + +### Prover.toml + +The _Prover.toml_ file is a file which the prover uses to supply his witness values(both private and +public). + +In our hello world program the _Prover.toml_ file looks like this: + +```toml +x = "1" +y = "2" +``` + +When the command `nargo prove` is executed, two processes happen: + +1. Noir creates a proof that `x`, which holds the value of `1`, and `y`, which holds the value of `2`, + is not equal. This inequality constraint is due to the line `assert(x != y)`. + +2. Noir creates and stores the proof of this statement in the _proofs_ directory in a file called your-project.proof. So if your project is named "private_voting" (defined in the project Nargo.toml), the proof will be saved at `./proofs/private_voting.proof`. Opening this file will display the proof in hex format. + +#### Arrays of Structs + +The following code shows how to pass an array of structs to a Noir program to generate a proof. + +```rust +// main.nr +struct Foo { + bar: Field, + baz: Field, +} + +fn main(foos: [Foo; 3]) -> pub Field { + foos[2].bar + foos[2].baz +} +``` + +Prover.toml: + +```toml +[[foos]] # foos[0] +bar = 0 +baz = 0 + +[[foos]] # foos[1] +bar = 0 +baz = 0 + +[[foos]] # foos[2] +bar = 1 +baz = 2 +``` + +#### Custom toml files + +You can specify a `toml` file with a different name to use for proving by using the `--prover-name` or `-p` flags. + +This command looks for proof inputs in the default **Prover.toml** and generates the proof and saves it at `./proofs/.proof`: + +```bash +nargo prove +``` + +This command looks for proof inputs in the custom **OtherProver.toml** and generates proof and saves it at `./proofs/.proof`: + +```bash +nargo prove -p OtherProver +``` + +## Verifying a Proof + +When the command `nargo verify` is executed, two processes happen: + +1. Noir checks in the _proofs_ directory for a proof file with the project name (eg. test_project.proof) + +2. If that file is found, the proof's validity is checked + +> **Note:** The validity of the proof is linked to the current Noir program; if the program is +> changed and the verifier verifies the proof, it will fail because the proof is not valid for the +> _modified_ Noir program. + +In production, the prover and the verifier are usually two separate entities. A prover would +retrieve the necessary inputs, execute the Noir program, generate a proof and pass it to the +verifier. The verifier would then retrieve the public inputs, usually from external sources, and +verify the validity of the proof against it. + +Take a private asset transfer as an example: + +A person using a browser as the prover would retrieve private inputs locally (e.g. the user's private key) and +public inputs (e.g. the user's encrypted balance on-chain), compute the transfer, generate a proof +and submit it to the verifier smart contract. + +The verifier contract would then draw the user's encrypted balance directly from the blockchain and +verify the proof submitted against it. If the verification passes, additional functions in the +verifier contract could trigger (e.g. approve the asset transfer). + +Now that you understand the concepts, you'll probably want some editor feedback while you are writing more complex code. diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.29.0/getting_started/installation/_category_.json b/noir/noir-repo/docs/versioned_docs/version-v0.29.0/getting_started/installation/_category_.json new file mode 100644 index 00000000000..0c02fb5d4d7 --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.29.0/getting_started/installation/_category_.json @@ -0,0 +1,6 @@ +{ + "position": 0, + "label": "Install Nargo", + "collapsible": true, + "collapsed": true +} diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.29.0/getting_started/installation/index.md b/noir/noir-repo/docs/versioned_docs/version-v0.29.0/getting_started/installation/index.md new file mode 100644 index 00000000000..4ef86aa5914 --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.29.0/getting_started/installation/index.md @@ -0,0 +1,48 @@ +--- +title: Nargo Installation +description: + nargo is a command line tool for interacting with Noir programs.

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("getSqrt", async (params) => { + const values = params[0].Array.map((field) => { + return `${Math.sqrt(parseInt(field, 16))}`; + }); + return { values: [{ Array: values }] }; +}); +``` + +:::tip + +Brillig expects an object with an array of values. Each value is an object declaring to be `Single` or `Array` and returning a field element *as a string*. For example: + +```json +{ "values": [{ "Array": ["1", "2"] }]} +{ "values": [{ "Single": "1" }]} +{ "values": [{ "Single": "1" }, { "Array": ["1", "2"] }]} +``` + +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[], +} +``` + +::: + +## Step 3 - Usage with Nargo + +Using the [`nargo` CLI tool](../getting_started/installation/index.md), you can use oracles in the `nargo test`, `nargo execute` and `nargo prove` 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.generateProof(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` or `nargo prove`? 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 to make the RPC request with the first parameter "numbers", which would be input[0] + const oracleReturn = await client.request(name, [ + { Array: input[0].map((i) => i.toString("hex")) }, + ]); + return [oracleReturn.values[0].Array]; +}; + +// 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. For development only, you can simply install and use the [`cors` npm package](https://www.npmjs.com/package/cors) to get around the problem: + +```bash +yarn add cors +``` + +and use it as a middleware: + +```js +import cors from "cors"; + +const app = express(); +app.use(cors()) +``` + +::: + +## Conclusion + +Hopefully by the end of this guide, you should be able to: + +- Write your own logic around Oracles and how to write a JSON RPC server to make them work with your Nargo commands. +- Provide custom foreign call handlers for NoirJS. diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.29.0/how_to/how-to-recursion.md b/noir/noir-repo/docs/versioned_docs/version-v0.29.0/how_to/how-to-recursion.md new file mode 100644 index 00000000000..4c45bb87ae2 --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.29.0/how_to/how-to-recursion.md @@ -0,0 +1,179 @@ +--- +title: How to use recursion on NoirJS +description: Learn how to implement recursion with NoirJS, a powerful tool for creating smart contracts on the EVM blockchain.

However, the guide should work just the same if you're using `noir_wasm`. + +:::info + +As you've read in the [explainer](../explainers/explainer-recursion.md), a recursive proof is an intermediate proof. This means that it doesn't necessarily generate the final step that makes it verifiable in a smart contract. However, it is easy to verify within another circuit. + +While "standard" usage of NoirJS packages abstracts final proofs, it currently lacks the necessary interface to abstract away intermediate proofs.

For the purpose of this guide, we will assume the following: + +- `main`: a circuit of type `assert(x != y)`, where `main` is marked with a `#[recursive]` attribute. This attribute states that the backend should generate proofs that are friendly for verification within another circuit. +- `recursive`: a circuit that verifies `main` + +For a full example on how recursive proofs work, please refer to the [noir-examples](https://github.com/noir-lang/noir-examples) repository. 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, backend) +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. In fact, if you're using recursive proofs, you're probably interested of using them this way! + +:::tip + +Managing circuits and "who does what" can be confusing. To make sure your naming is consistent, you can keep them in an object. For example: + +```js +const circuits = { + main: mainJSON, + recursive: recursiveJSON +} +const backends = { + main: new BarretenbergBackend(circuits.main), + recursive: new BarretenbergBackend(circuits.recursive) +} +const noir_programs = { + main: new Noir(circuits.main, backends.main), + recursive: new Noir(circuits.recursive, backends.recursive) +} +``` + +This allows you to neatly call exactly the method you want without conflicting names: + +```js +// Alice runs this 👇 +const { witness: mainWitness } = await noir_programs.main.execute(input) +const proof = await backends.main.generateProof(mainWitness) + +// Bob runs this 👇 +const verified = await backends.main.verifyProof(proof) +const { proofAsFields, vkAsFields, vkHash } = await backends.main.generateRecursiveProofArtifacts( + proof, + numPublicInputs, +); +const recursiveProof = await noir_programs.recursive.generateProof(recursiveInputs) +``` + +::: diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.29.0/how_to/how-to-solidity-verifier.md b/noir/noir-repo/docs/versioned_docs/version-v0.29.0/how_to/how-to-solidity-verifier.md new file mode 100644 index 00000000000..e3c7c1065da --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.29.0/how_to/how-to-solidity-verifier.md @@ -0,0 +1,231 @@ +--- +title: Generate a Solidity Verifier +description: + Learn how to run the verifier as a smart contract on the blockchain.

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.

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 read 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 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. For `_proof`, run `nargo prove` and use the string in `proof/.proof` (adding the hex `0x` prefix). We can also copy the public input from `Verifier.toml`, as it will be properly formatted as 32-byte strings: + +``` +0x...... , [0x0000.....02] +``` + +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. Like before, these values are populated in Verifier.toml after running `nargo prove`. + +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 + +ZK-SNARK verification depends on some precompiled cryptographic primitives such as Elliptic Curve Pairings (if you like complex math, you can read about EC Pairings [here](https://medium.com/@VitalikButerin/exploring-elliptic-curve-pairings-c73c1864e627)). 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. + +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 + +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!

Each trait defines +the interface of several methods contained within the trait. Types can then implement this trait by providing +implementations for these methods. For example in the program: + +```rust +struct Rectangle { + width: Field, + height: Field, +} + +impl Rectangle { + fn area(self) -> Field { + self.width * self.height + } +} + +fn log_area(r: Rectangle) { + println(r.area()); +} +``` + +We have a function `log_area` to log the area of a `Rectangle`. Now how should we change the program if we want this +function to work on `Triangle`s as well?: + +```rust +struct Triangle { + width: Field, + height: Field, +} + +impl Triangle { + fn area(self) -> Field { + self.width * self.height / 2 + } +} +``` + +Making `log_area` generic over all types `T` would be invalid since not all types have an `area` method. Instead, we can +introduce a new `Area` trait and make `log_area` generic over all types `T` that implement `Area`: + +```rust +trait Area { + fn area(self) -> Field; +} + +fn log_area(shape: T) where T: Area { + println(shape.area()); +} +``` + +We also need to explicitly implement `Area` for `Rectangle` and `Triangle`. We can do that by changing their existing +impls slightly. Note that the parameter types and return type of each of our `area` methods must match those defined +by the `Area` trait. + +```rust +impl Area for Rectangle { + fn area(self) -> Field { + self.width * self.height + } +} + +impl Area for Triangle { + fn area(self) -> Field { + self.width * self.height / 2 + } +} +``` + +Now we have a working program that is generic over any type of Shape that is used! Others can even use this program +as a library with their own types - such as `Circle` - as long as they also implement `Area` for these types. + +## Where Clauses + +As seen in `log_area` above, when we want to create a function or method that is generic over any type that implements +a trait, we can add a where clause to the generic function. + +```rust +fn log_area(shape: T) where T: Area { + println(shape.area()); +} +``` + +It is also possible to apply multiple trait constraints on the same variable at once by combining traits with the `+` +operator. Similarly, we can have multiple trait constraints by separating each with a comma: + +```rust +fn foo(elements: [T], thing: U) where + T: Default + Add + Eq, + U: Bar, +{ + let mut sum = T::default(); + + for element in elements { + sum += element; + } + + if sum == T::default() { + thing.bar(); + } +} +``` + +## Generic Implementations + +You can add generics to a trait implementation by adding the generic list after the `impl` keyword: + +```rust +trait Second { + fn second(self) -> Field; +} + +impl Second for (T, Field) { + fn second(self) -> Field { + self.1 + } +} +``` + +You can also implement a trait for every type this way: + +```rust +trait Debug { + fn debug(self); +} + +impl Debug for T { + fn debug(self) { + println(self); + } +} + +fn main() { + 1.debug(); +} +``` + +### Generic Trait Implementations With Where Clauses + +Where clauses can also be placed on trait implementations themselves to restrict generics in a similar way. +For example, while `impl Foo for T` implements the trait `Foo` for every type, `impl Foo for T where T: Bar` +will implement `Foo` only for types that also implement `Bar`. This is often used for implementing generic types. +For example, here is the implementation for array equality: + +```rust +impl Eq for [T; N] 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 + } +} +``` + +## 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); +} +``` + +## 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: dep::some_library::Foo, +} + +impl Default for Wrapper { + fn default() -> Wrapper { + Wrapper { + foo: dep::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. diff --git a/noir/noir-repo/docs/versioned_docs/version-v0.29.0/noir/concepts/unconstrained.md b/noir/noir-repo/docs/versioned_docs/version-v0.29.0/noir/concepts/unconstrained.md new file mode 100644 index 00000000000..b8e71fe65f0 --- /dev/null +++ b/noir/noir-repo/docs/versioned_docs/version-v0.29.0/noir/concepts/unconstrained.md @@ -0,0 +1,99 @@ +--- +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).

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 = 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). + +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.

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 +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.

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 +const setup = async () => { + await Promise.all([ + import('@noir-lang/noirc_abi').then((module) => + module.default(new URL('@noir-lang/noirc_abi/web/noirc_abi_wasm_bg.wasm', import.meta.url).toString()), + ), + import('@noir-lang/acvm_js').then((module) => + module.default(new URL('@noir-lang/acvm_js/web/acvm_js_bg.wasm', import.meta.url).toString()), + ), + ]); +}; + +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 😢 + +As for the `setup` function, it's just a sad reminder that dealing with `wasm` on the browser is not as easy as it should. Just copy, paste, and forget. + +:::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, backend); +// } +``` + +:::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 proof = await noir.generateProof(input); +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 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. diff --git a/noir/noir-repo/docs/versioned_sidebars/version-v0.28.0-sidebars.json b/noir/noir-repo/docs/versioned_sidebars/version-v0.28.0-sidebars.json new file mode 100644 index 00000000000..b9ad026f69f --- /dev/null +++ b/noir/noir-repo/docs/versioned_sidebars/version-v0.28.0-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": "
