# snarkjs: JavaScript implementation of zkSNARKs. # snarkjs: JavaScript implementation of zkSNARKs.
This is a JavaScript implementation of zkSNARK schemes. It allows the original 8points protocol This is a JavaScript and Pure Web Assembly implementation of zkSNARK schemes. It uses the Groth16 Protocol (3 point only and 3 pairings)
and the Groth Protocol (3 point only and 3 pairings)
This library allows to do the trusted setup, generate proofs and verify the proofs. This library includes all the tools for the Trusted setup multiparty ceremony.
This includes the universal ceremony "powers of tau".
And the per circuit phase 2 ceremony.
This library uses the compiled circuits generated by the jaz compiler. The formats used in this library for the multipary computation are compatible with the ones used in other (implementations in rust)[].
### Tutorial. This library uses the compiled circuits generated by the circom compiler.
A good starting point [is this tutorial](https://github.com/iden3/circom/blob/master/TUTORIAL.md) The library works in nodejs and browser.
Also this [video](https://www.youtube.com/watch?v=-9TJa1hVsKA) is a good starting point. It's a ESM module, so it can be directly imported from bigger projects using rollup or webpack.
## Install. The low level criptography is done directly in wasm. And it uses working threads to parallelize the computations. The result is a high performance library with benchmarks comparable with implementations running in the host.
## Usage / Tutorial.
### Install snarkjs and circom
```sh ```sh
npm install snarkjs npm install -g circom
npm install -g snarkjs
``` ```
## Usage from command line. ### Help
```sh ```sh
snarkjs --help snarkjs --help
``` ```
Will show all the info in how to use the cli. In commands that takes long time, you can add the -v or --verbose option to see the progress.
## Usage from javascript The help for specific command:
Example
### Import. ```sh
snarkjs groth16 prove --help
```js
const zkSnark = require("snarkjs");
``` ```
### Load a circuit. Most of the commands have a shor alias.
```js For example, the previos command can also be invoked as:
// "myCircuit.cir" is the output of the jaz compiler
const circuitDef = JSON.parse(fs.readFileSync("myCircuit.cir", "utf8")); ```sh
const circuit = new zkSnark.Circuit(circuitDef); snarkjs g16p --help
``` ```
### Inspect the circuit.
```js ### Start a new ceremony.
// `signalId` can always be a number or an alias string
circuit.nConstraints; // number of constraints ```sh
circuit.nSignals; // number of signals snarkjs powersoftau new bn128 12 pot12_0000.ptau
circuit.nPublic; // number of public signals (nOutputs + nPublicInputs)
// The array of signals is always sorted in this order:
// [ 1, outputs, publicInputs, privateInputs, internalSignals, constants]
// returns a,b and c coeficients of the `signalId` on a given `constraint`
circuit.a(constraint, signalId)
circuit.b(constraint, signalId)
circuit.c(constraint, signalId)
circuit.nOutputs // number of public outputs
circuit.pubInputs // number of public inputs
circuit.nPrvInputs // number of private inputs
circuit.nInputs // number of inputs ( nPublicInputs + nPrivateInputs)
circuit.nVars // number of variables ( not including constants (one is a variable) )
circuit.nSignals // number of signals ( including constants )
circuit.outputIdx(i) // returns the index of the i'th output
circuit.inputIdx(i) // returns the index of the i'th input
circuit.pubInputIdx(i) // returns the index of the i'th public input
circuit.prvInputIdx(i) // returns the index of the i'th private input
circuit.varIdx(i) // returns the index of the i'th variable
circuit.constantIdx(i) // returns the index of the i'th constant
circuit.signalIdx(i) // returns the index of the i'th signal
// returns signal Idx given a signalId
// if the idx >= n , it is a constant
// if the idx == -1, the signal does not exist
circuit.getSignalIdx(name);
// returns an array aliases names of the i'th signal
circuit.signalNames(i)
// input is a key value object where keys are the signal names
// of all the inputs (public and private)
// returns an array of values representing the witness
circuit.calculateWitness(input)
``` ```
### Trusted setup. You can also use bls12-381 as the curve.
```js The secons parameter is the power of two of the maximum number of contraints that can accept this ceremony.
const setup = zkSnark.setup(circuit);
fs.writeFileSync("myCircuit.vk_proof", JSON.stringify(setup.vk_proof), "utf8"); In this case 12 means that the maximum constraints will be 2**12 = 4096
fs.writeFileSync("myCircuit.vk_verifier", JSON.stringify(setup.vk_verifier), "utf8");
setup.toxic // Must be discarded. ### Contribute in the ceremony
```sh
snarkjs powersoftau contribute pot12_0000.ptau pot12_0001.ptau --name="Example Name" -v
``` ```
### Generate proof. The name is a random name and it's include for reference. It's printed in the verification.
```js ### Do a second contribution
const circuitDef = JSON.parse(fs.readFileSync("myCircuit.cir", "utf8")); ```sh
const circuit = new zkSnark.Circuit(circuitDef); snarkjs powersoftau contribute pot12_0001.ptau pot12_0002.ptau --name="Second contribution Name" -v -e="some random text"
const input = { ```
"main.pubIn1": "123",
"main.out1": "456" the -e parameter allows the comman to be non interactive and use this text as an extra source of entropy for the random generation.
### Verify the file
```sh
snarkjs powersoftau verify pot12_0002.ptau
```
This command checks all the contributions of the Multiparty Computation (MPC) and list the hashes of the
intermediary results.
### Contribute using ther party software.
```sh
snarkjs powersoftau export challange pot12_0002.ptau challange_0003
snarkjs powersoftau challange contribute bn128 challange_0003 response_0003
snarkjs powersoftau import response pot12_0002.ptau response_0003 pot12_0003.ptau -n="Third contribution name"
```
### Add a beacon
```sh
snarkjs powersoftau beacon pot12_0003.ptau pot12_beacon.ptau 0102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f 10 -n="Final Beacon"
```
### Prepare phase2
```sh
powersoftau prepare phase2 pot12_beacon.ptau pot12_final.ptau -v
```
### Verify the last file
```sh
snarkjs powersoftau verify pot12_final.ptau
```
### Create a circuit
```sh
mkdir mycircuit
cd my mycircuit
cat <<EOT > circuit.circom
template Multiplier(n) {
signal private input a;
signal private input b;
signal output c;
signal int[n];
int[0] <== a*a + b;
for (var i=1; i<n; i++) {
int[i] <== int[i-1]*int[i-1] + b;
} }
const witness = circuit.calculateWitness(input);
const vk_proof = JSON.parse(fs.readFileSync("myCircuit.vk_proof", "utf8"));
const {proof, publicSignals} = zkSnark.genProof(vk_proof, witness); c <== int[n-1];
}
component main = Multiplier(1000);
EOT
``` ```
### Verifier. This is an example circom fille that allows to test the system with different number of contraints.
In this case 1000, but it can be changed to any nomber of constraints.
### compile the circuit
```sh
circom circuit.circom -r -w -s -v
```
-r to generate the .r1cs file
-w to generate the .wasm file that computes the witness from an input.
-s to generate the .sym file that contains the human readable names of all signals. (Important to debug the circuit)
-v Verbose. To see the progress of the compilation.
### info of a circuit
```sh
snarkjs r1cs info circuit.r1cs
```
### Print the constraints
```sh
snarkjs r1cs print circuit.r1cs
```
### export r1cs to json
```sh
snarkjs r1cs export json circuit.r1cs circuit.r1cs.json
```
### Generate the reference zKey without contributions from the circuit.
```sh
snarkjs zkey new circuit.r1cs pot12_final.ptau circuit_0000.zkey
```
circuit_0000.zkey does not include any contribution yet, so it cannot be used in a final circuit.
### Contribute in the phase2 ceremony
```sh
snarkjs zkey contribute circuit_0000.zkey circuit_0001.zkey --name="1st Contributor Name" -v
```
### Do a second phase2 contribution
```sh
snarkjs zkey contribute circuit_0001.zkey circuit_0002.zkey --name="Second contribution Name" -v -e="Another random entropy"
```
### Verify the zkey file
```sh
snarkjs zkey verify circuit.r1cs pot12_final.ptau circuit_0002.zkey
```
### Contribute using third party software.
```sh
snarkjs zkey export bellman circuit_0002.zkey challange_phase2_0003
snarkjs zkey bellman contribute bn128 challange_phase2_0003 response_phase2_0003
snarkjs zkey import bellman circuit_0002.zkey response_phase2_0003 circuit_0003.zkey -n="Third contribution name"
```
### Add a beacon
```sh
snarkjs zkey beacon circuit_0003.zkey circuit_final.zkey 0102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f 10 -n="Final Beacon phase2"
```
### Verify the final file
```sh
snarkjs zkey verify circuit.r1cs pot12_final.ptau circuit_final.zkey
```
### Export the verification key
```sh
snarkjs zkey export verificationkey circuit_final.zkey verification_key.json
```
### Calculat witess
```sh
cat <<EOT > input.json
{"a": 3, "b": 11}
EOT
snarkjs wtns calculate circuit.wasm input.json witness.wtns
```
### Debug witness calculation
In general, when you are developing a new circuit you will want to check for some errors in the witness calculation process.
You can do it by doing
```sh
snarkjs wtns debug circuit.wasm input.json witness.wtns circuit.sym --trigger --get --set
```
This will log every time a new component is started/ended ( --trigger ) when a signal is set (--set) and when it's get (--get)
### Proof calculation
```sh
snarkjs groth16 prove circuit_final.zkey witness.wtns proof.json public.json
```
It is possible also to do the calculate witness and the prove calculation in the same command:
```sh
snarkjs groth16 fullprove input.json circuit.wasm circuit_final.zkey proof.json public.json
```
### Verify
```sh
snarkjs groth16 verify verification_key.json public.json proof.json
```
### Export Solidity Verifier
```sh
snarkjs zkey export solidityverifier circuit_final.zkey verifier.sol
```
You can deploy th "Verifier" smartcontract using remix for example.
In order to simulate a verification call, you can do:
```sh
zkey export soliditycalldata public.json proof.json
```
And cut and paste the resolt directlly in the "verifyProof" field in the deployed smart contract.
This call will return true if the proof and the public data is valid.
## Use in node
```sh
npm install snarkjs
```
```js ```js
const vk_verifier = JSON.parse(fs.readFileSync("myCircuit.vk_verifier", "utf8")); const snarkjs = require("snarkjs");
const fs = require("fs");
if (zkSnark.isValid(vk_verifier, proof, publicSignals)) { async function run() {
console.log("The proof is valid"); const { proof, publicSignals } = await snarkjs.groth16.fullProve({a: 10, b: 21}, "circuit.wasm", "circuit_final.zkey");
console.log("Proof: ");
console.log(JSON.stringify(proof, null, 1));
const vKey = JSON.parse(fs.readFileSync("verification_key.json"));
const res = await snarkjs.groth16.verify(vKey, publicSignals, proof);
if (res === true) {
console.log("Verification OK");
} else { } else {
console.log("The proof is not valid"); console.log("Invalid proof");
} }
}
run().then(() => {
process.exit(0);
});
``` ```
