Expand description
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 as PairingEngine>::G1Affine), Global>>
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
Find the appropriate shift for the degree bound.
