UniversalParams are the universal parameters for the MarlinPST13 scheme.

Fields

powers_of_g: BTreeMap<P::Term, E::G1Affine>

Contains group elements corresponding to all possible monomials with num_vars and maximum degree max_degree evaluated at \beta

gamma_g: E::G1Affine

\gamma times the generater of G1

powers_of_gamma_g: Vec<Vec<E::G1Affine>>

Group elements of the form { \beta_i^j \gamma G }, where i ranges from 0 to num_vars-1 and j ranges from 1 to max_degree+1.

h: E::G2Affine

The generator of G2.

beta_h: Vec<E::G2Affine>

Group elements of the form { \beta_i H }, where i ranges from 0 to num_vars-1

prepared_h: E::G2Prepared

The generator of G2, prepared for use in pairings.

prepared_beta_h: Vec<E::G2Prepared>
