Struct snarkvm_wasm::kzg10::KZG10

pub struct KZG10<E>(_)
 where
    E: PairingEngine;

KZG10 is an implementation of the polynomial commitment scheme of Kate, Zaverucha and Goldbgerg

Implementations

impl<E> KZG10<E> where
    E: PairingEngine, 

pub fn setup<R>(
    max_degree: usize,
    produce_g2_powers: bool,
    rng: &mut R
) -> Result<UniversalParams<E>, Error> where
    R: RngCore, 

Constructs public parameters when given as input the maximum degree degree for the polynomial commitment scheme.

pub fn commit(
    powers: &Powers<'_, E>,
    polynomial: &DensePolynomial<<E as PairingEngine>::Fr>,
    hiding_bound: Option<usize>,
    rng: Option<&mut dyn RngCore>
) -> Result<(Commitment<E>, Randomness<E>), Error>

Outputs a commitment to polynomial.

pub fn compute_witness_polynomial(
    polynomial: &DensePolynomial<<E as PairingEngine>::Fr>,
    point: <E as PairingEngine>::Fr,
    randomness: &Randomness<E>
) -> Result<(DensePolynomial<<E as PairingEngine>::Fr>, Option<DensePolynomial<<E as PairingEngine>::Fr>>), Error>

Compute witness polynomial.

The witness polynomial w(x) the quotient of the division (p(x) - p(z)) / (x - z) Observe that this quotient does not change with z because p(z) is the remainder term. We can therefore omit p(z) when computing the quotient.

pub fn check(
    vk: &VerifierKey<E>,
    commitment: &Commitment<E>,
    point: <E as PairingEngine>::Fr,
    value: <E as PairingEngine>::Fr,
    proof: &Proof<E>
) -> Result<bool, Error>

Verifies that value is the evaluation at point of the polynomial committed inside commitment.

pub fn batch_check<R>(
    vk: &VerifierKey<E>,
    commitments: &[Commitment<E>],
    points: &[<E as PairingEngine>::Fr],
    values: &[<E as PairingEngine>::Fr],
    proofs: &[Proof<E>],
    rng: &mut R
) -> Result<bool, Error> where
    R: RngCore, 

Check that each proof_i in proofs is a valid proof of evaluation for commitment_i at point_i.
