func BatchProve(pk []ProvingKey, values [][]fr.Element, fiatshamirSeeds ...[]byte) (pok curve.G1Affine, err error)

BatchProve generates a single proof of knowledge for multiple commitments for faster verification

func FoldCommitments(commitments []curve.G1Affine, fiatshamirSeeds ...[]byte) (commitment curve.G1Affine, err error)

FoldCommitments amalgamates multiple commitments into one, which can be verifier against a folded proof obtained from BatchProve
