UniversalParams are the universal parameters for the KZG10 scheme.

Fields

h: E::G2Affine

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

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