Struct snarkvm_polycommit::marlin_pc::VerifierKey

pub struct VerifierKey<E: PairingEngine> {
    pub vk: VerifierKey<E>,
    pub degree_bounds_and_shift_powers: Option<Vec<(usize, E::G1Affine)>>,
    pub max_degree: usize,
    pub supported_degree: usize,
}

VerifierKey is used to check evaluation proofs for a given commitment.

Fields

vk: VerifierKey<E>

The verification key for the underlying KZG10 scheme.

degree_bounds_and_shift_powers: Option<Vec<(usize, E::G1Affine)>>

Information required to enforce degree bounds. Each pair is of the form (degree_bound, shifting_advice). The vector is sorted in ascending order of degree_bound. This is None if self does not support enforcing any degree bounds.

max_degree: usize

The maximum degree supported by the UniversalParams self was derived from.

supported_degree: usize

The maximum degree supported by the trimmed parameters that self is a part of.

Implementations

impl<E: PairingEngine> VerifierKey<E>

pub fn get_shift_power(&self, bound: usize) -> Option<E::G1Affine>

Find the appropriate shift for the degree bound.
