Struct snarkvm_algorithms::polycommit::kzg10::KZGRandomness

pub struct KZGRandomness<E: PairingEngine> {
    pub blinding_polynomial: DensePolynomial<E::Fr>,
}

KZGRandomness hides the polynomial inside a commitment. It is output by KZG10::commit.

Fields

blinding_polynomial: DensePolynomial<E::Fr>

For KZG10, the commitment randomness is a random polynomial.

Implementations

impl<E: PairingEngine> KZGRandomness<E>

pub fn is_hiding(&self) -> bool

Does self provide any hiding properties to the corresponding commitment? self.is_hiding() == true only if the underlying polynomial is non-zero.

pub fn calculate_hiding_polynomial_degree(hiding_bound: usize) -> usize

What is the degree of the hiding polynomial for a given hiding bound?
