Expand description
VerifierKey
is used to check evaluation proofs for a given commitment.
Fields
g: E::G1Affine
The generator of G1.
gamma_g: E::G1Affine
The generator of G1 that is used for making a commitment hiding.
h: E::G2Affine
The generator of G2.
beta_h: E::G2Affine
\beta times the generator of G2.
prepared_h: <E::G2Affine as PairingCurve>::Prepared
The generator of G2, prepared for use in pairings.
prepared_beta_h: <E::G2Affine as PairingCurve>::Prepared
The \beta times the generator of G2, prepared for use in pairings.
degree_bounds_and_prepared_neg_powers_of_h: Option<Vec<(usize, <E::G2Affine as PairingCurve>::Prepared)>>
Pairs a degree_bound with its corresponding G2 element, which has been prepared for use in pairings.
Each pair is in the form (degree_bound, \beta^{degree_bound - max_degree} h),
where h
is the generator of G2 above
supported_degree: usize
The maximum degree supported by the trimmed parameters that self
is
a part of.
max_degree: usize
The maximum degree supported by the UniversalParams
self
was derived
from.
