Expand description

A (not necessarily hiding) polynomial commitment scheme, for committing to (batches of) polynomials

Required Associated Types§

source

type Domain: PolynomialSpace

source

type Commitment: Clone + Serialize + DeserializeOwned

The commitment that’s sent to the verifier.

source

type ProverData: Clone

Data that the prover stores for committed polynomials, to help the prover with opening.

source

type Proof: Clone + Serialize + DeserializeOwned

The opening argument.

source

type Error: Debug

Required Methods§

source

fn natural_domain_for_degree(&self, degree: usize) -> Self::Domain

This should return a coset domain (s.t. Domain::next_point returns Some)

source

fn commit( &self, evaluations: Vec<(Self::Domain, RowMajorMatrix<Val<Self::Domain>>)>, ) -> (Self::Commitment, Self::ProverData)

source

fn get_evaluations_on_domain<'a>( &self, prover_data: &'a Self::ProverData, idx: usize, domain: Self::Domain, ) -> impl Matrix<Val<Self::Domain>> + 'a

source

fn open( &self, rounds: Vec<(&Self::ProverData, Vec<Vec<Challenge>>)>, challenger: &mut Challenger, ) -> (OpenedValues<Challenge>, Self::Proof)

source

fn verify( &self, rounds: Vec<(Self::Commitment, Vec<(Self::Domain, Vec<(Challenge, Vec<Challenge>)>)>)>, proof: &Self::Proof, challenger: &mut Challenger, ) -> Result<(), Self::Error>
