[][src]Module snarkos_polycommit::kzg10

The core [KZG10] construction.

Here we construct a polynomial commitment that enables users to commit to a single polynomial p, and then later provide an evaluation proof that convinces verifiers that a claimed value v is the true evaluation of p at a chosen point x. Our construction follows the template of the construction proposed by Kate, Zaverucha, and Goldberg (KZG11). This construction achieves extractability in the algebraic group model (AGM).

Structs

Commitment

Commitment commits to a polynomial. It is output by KZG10::commit.

KZG10

KZG10 is an implementation of the polynomial commitment scheme of Kate, Zaverucha and Goldbgerg

Powers

Powers is used to commit to and create evaluation proofs for a given polynomial.

Proof

Proof is an evaluation proof that is output by KZG10::open.

Randomness

Randomness hides the polynomial inside a commitment. It is output by KZG10::commit.

UniversalParams

UniversalParams are the universal parameters for the KZG10 scheme.

VerifierKey

VerifierKey is used to check evaluation proofs for a given commitment.
