Proof generator for creating zk-SNARKs

Implementations§

Source§

impl ProofGenerator

Source

pub fn new() -> Self

Create new proof generator

Source

pub fn generate_proving_key( &self, circuit: &ArithmeticCircuit, ) -> Result<ProvingKey, ZkError>

Generate proving key

Uses a deterministic hash-based scheme (SHA3-512 + HKDF-style expansion). Bytes [0..8] are set to the discriminant b"QUALAPK\x01" so proving and verifying keys are unambiguously distinguishable.

Source

pub fn store_proving_key(&mut self, circuit_id: String, proving_key: ProvingKey)

Store proving key

Source

pub fn get_proving_key(&self, circuit_id: &str) -> Result<&ProvingKey, ZkError>

Get proving key
