Input a circuit and the SRS, precompute the proving key and verification key.

fn prove<C, R, T>( rng: &mut R, circuit: &C, prove_key: &Self::ProvingKey, extra_transcript_init_msg: Option<Vec<u8>>, ) -> Result<Self::Proof, Self::Error>
where C: Arithmetization<E::ScalarField>, R: CryptoRng + RngCore, T: PlonkTranscript<F>,

Compute a Plonk proof. Refer to Sec 8.4 of https://eprint.iacr.org/2019/953.pdf

circuit and prove_key has to be consistent (with the same evaluation domain etc.), otherwise return error.

Source§

type Proof = Proof<E>

The SNARK proof computed by the prover.
Source§

type ProvingKey = ProvingKey<E>

The parameters required by the prover to compute a proof for a specific circuit.
Source§

type VerifyingKey = VerifyingKey<E>

The parameters required by the verifier to validate a proof for a specific circuit.
Source§

type UniversalSRS = UnivariateUniversalParams<E>

Universal Structured Reference String from universal_setup, used for all subsequent circuit-specific preprocessing
Source§

type Error = PlonkError

SNARK related error
Source§

fn verify<T>( verify_key: &Self::VerifyingKey, public_input: &[E::ScalarField], proof: &Self::Proof, extra_transcript_init_msg: Option<Vec<u8>>, ) -> Result<(), Self::Error>
where T: PlonkTranscript<F>,

Verify a SNARK proof proof of the circuit circuit, with respect to the public input pub_input. Read more
Source§

fn universal_setup<R: RngCore + CryptoRng>( _max_degree: usize, _rng: &mut R, ) -> Result<Self::UniversalSRS, Self::Error>

Generate the universal SRS for the argument system. This setup is for trusted party to run, and mostly only used for testing purpose. In practice, a MPC flavor of the setup will be carried out to have higher assurance on the “toxic waste”/trapdoor being thrown away to ensure soundness of the argument system.
