Expand description

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

Fields

prepared_vk: PreparedVerifierKey<E>

The verification key for the underlying KZG10 scheme.

degree_bounds_and_prepared_neg_powers_of_h: Option<Vec<(usize, <E::G2Affine as PairingCurve>::Prepared)>>

Information required to enforce degree bounds. Each pair is of the form (degree_bound, shifting_advice). 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> PreparedVerifierKey<E>

pub fn get_prepared_shift_power(
&self,
bound: usize
) -> Option<<E::G2Affine as PairingCurve>::Prepared>
