Struct snarkvm_algorithms::polycommit::sonic_pc::SonicKZG10

pub struct SonicKZG10<E: PairingEngine, S: AlgebraicSponge<E::Fq, 2>> { /* private fields */ }

Polynomial commitment based on [KZG10], with degree enforcement and batching taken from [MBKM19, “Sonic”] (more precisely, their counterparts in [Gabizon19, “AuroraLight”] that avoid negative G1 powers). The (optional) hiding property of the commitment scheme follows the approach described in [CHMMVW20, “Marlin”].

    pp: &UniversalParams<E>,
    supported_degree: usize,
    supported_lagrange_sizes: impl IntoIterator<Item = usize>,

    rng: Option<&mut dyn RngCore>
) -> Result<(Vec<LabeledCommitment<Commitment<E>>>, Vec<Randomness<E>>), PCError>

Outputs a commitments to polynomials. If polynomials[i].is_hiding(), then the i-th commitment is hiding up to polynomials.hiding_bound() queries. rng should not be None if polynomials[i].is_hiding() == true for any i.

If for some i, polynomials[i].is_hiding() == false, then the corresponding randomness is Randomness<E>::empty().

If for some i, polynomials[i].degree_bound().is_some(), then that polynomial will have the corresponding degree bound enforced.

    terminator: &AtomicBool,

) -> Result<(Vec<LabeledCommitment<Commitment<E>>>, Vec<Randomness<E>>), PCError>

Outputs a commitment to polynomial.

On input a list of labeled polynomials and a query set, open outputs a proof of evaluation of the polynomials at the points in the query set.
