Expand description

UniversalParams are the universal parameters for the KZG10 scheme.

Fields

powers_of_g: Vec<E::G1Affine>

Group elements of the form { \beta^i G }, where i ranges from 0 to degree.

powers_of_gamma_g: BTreeMap<usize, E::G1Affine>

Group elements of the form { \beta^i \gamma G }, where i ranges from 0 to degree.

h: E::G2Affine

The generator of G2.

beta_h: E::G2Affine

\beta times the above generator of G2.

supported_degree_bounds: Vec<usize>

Supported degree bounds.

inverse_powers_of_g: BTreeMap<usize, E::G1Affine>

Group elements of the form { \beta^{max_degree - i} G1}, where i is the supported degree bound. This one is used for deriving the verifying key.

inverse_neg_powers_of_h: BTreeMap<usize, E::G2Affine>

Group elements of the form { \beta^{max_degree -i} G2 }, where i is the supported degree bound. This one is used for deriving the verifying key.

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.
