RISC Zero Solana Groth16 Verifier

This is unaudited and not for production use.

A RISC Zero Groth16 SNARK verifier compatible with Solana. This library provides functionality for verifying RISC Zero proofs on the Solana blockchain.

Usage

Verifying a Proof

use risc0_groth16_verifier::{verify_proof, Proof, PublicInputs, VerificationKey};

let proof: Proof = // ... load or deserialize proof
let public_inputs: PublicInputs<5> = // ... load or deserialize public inputs
let vk: VerificationKey = // ... load or deserialize verification key

let result = verify_proof(&proof, &public_inputs, &vk);
assert!(result.is_ok(), "Proof verification failed");

Generating Public Inputs

use risc0_groth16_verifier::public_inputs;

let claim_digest: [u8; 32] = // ... obtain claim digest
let allowed_control_root: &str = // ... specify allowed control root
let bn254_identity_control_id: &str = // ... specify BN254 identity control ID

let public_inputs = public_inputs(claim_digest, allowed_control_root, bn254_identity_control_id)?;

Working with Proofs and Verification Keys

The library provides utilities for serializing and deserializing proofs and verification keys:

use risc0_groth16_verifier::client::{Proof, VerificationKey};

// Serialize to JSON
let proof_json = serde_json::to_string(&proof)?;
let vk_json = serde_json::to_string(&vk)?;

// Deserialize from JSON
let proof: Proof = serde_json::from_str(&proof_json)?;
let vk: VerificationKey = serde_json::from_str(&vk_json)?;

Client-side Utilities

The library includes client-side utilities for working with proofs and verification keys:

• Compression of G1 and G2 points
• Conversion between JSON and binary formats
• Writing proofs and verification keys to files

Testing

The library includes a non-exhuastive test suite. Run the tests using:

cargo test
