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::G2Prepared

The generator of G2, prepared for use in pairings.

prepared_beta_h: E::G2Prepared

The \beta times the generator of G2, prepared for use in pairings.

degree_bounds_and_neg_powers_of_h: Option<Vec<(usize, E::G2Affine)>>

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.
