Abstract
A method for providing a zero-knowledge membership proof is provided. The method comprises defining public parameters to be used for computing and verification of proof by a prover and a verifier, respectively. The method comprises computing, by the prover, a commitment to a given ordered set X using the public parameters, and sending it to the verifier. The method further comprises receiving, by the prover, a query from the verifier for proving membership of a subset S sampled from the given ordered set X. The method further comprises computing, by the prover, a proof of membership, including an inner product, commitments of polynomials defining the inner product and a proof of the inner product being correctly computed, and sending the proof of membership to the verifier. The method further comprises verifying, by the verifier, the proof of membership based on the defined public parameters.
