Expand description
ProverSRS is the specialized SRS version for the prover for a specific number of proofs to aggregate. It contains as well the commitment keys for this specific size. Note the size must be a power of two for the moment - if it is not, padding must be applied.
Fields§
§n: usize
number of proofs to aggregate
g_alpha_powers_table: MultiscalarPrecompOwned<E::G1Affine>
${g^a^i}_{i=0}^{2n-1}$ where n is the number of proofs to be aggregated We take all powers instead of only ones from n -> 2n-1 (w commitment key is formed from these powers) since the prover will create a shifted polynomial of degree 2n-1 when doing the KZG opening proof.
h_alpha_powers_table: MultiscalarPrecompOwned<E::G2Affine>
${h^a^i}_{i=0}^{n-1}$ - here we don’t need to go to 2n-1 since v commitment key only goes up to n-1 exponent.
g_beta_powers_table: MultiscalarPrecompOwned<E::G1Affine>
${g^b^i}_{i=0}^{2n-1}$
h_beta_powers_table: MultiscalarPrecompOwned<E::G2Affine>
${h^b^i}_{i=0}^{n-1}$
vkey: VKey<E>
commitment key using in MIPP and TIPP
wkey: WKey<E>
commitment key using in TIPP
