Struct snarkvm_algorithms::snark::marlin::MarlinSNARK

pub struct MarlinSNARK<E: PairingEngine, FS: AlgebraicSponge<E::Fq, 2>, MM: MarlinMode, Input: ToConstraintField<E::Fr> + ?Sized>(_);

The Marlin proof system.

Implementations

impl<E: PairingEngine, FS: AlgebraicSponge<E::Fq, 2>, MM: MarlinMode, Input: ToConstraintField<E::Fr> + ?Sized> MarlinSNARK<E, FS, MM, Input>

pub const PROTOCOL_NAME: &'static [u8] = b"MARLIN-2019"

The personalization string for this protocol. Used to personalize the Fiat-Shamir RNG.

pub fn circuit_specific_setup<C: ConstraintSynthesizer<E::Fr>, R: RngCore + CryptoRng>(
    c: &C,
    rng: &mut R
) -> Result<(CircuitProvingKey<E, MM>, CircuitVerifyingKey<E, MM>), SNARKError>

Generate the index-specific (i.e., circuit-specific) prover and verifier keys. This is a trusted setup.

Warning

This method should be used only for testing purposes, and not in production. In production, one should instead perform a universal setup via Self::universal_setup, and then deterministically specialize the resulting universal SRS via Self::circuit_setup.

pub fn circuit_setup<C: ConstraintSynthesizer<E::Fr>>(
    universal_srs: &UniversalSRS<E>,
    circuit: &C
) -> Result<(CircuitProvingKey<E, MM>, CircuitVerifyingKey<E, MM>), SNARKError>

Generates the circuit proving and verifying keys. This is a deterministic algorithm that anyone can rerun.
