Abstract
The invention relates to a method of enabling zero-knowledge proof or verification of a statement (S) for enabling exchange of data between a prover and a verifier, wherein the prover has access to first data on a first blockchain, and the verifier has access to second data on a second blockchain. In the method, a prover sends to a verifier a set of data including a statement, which for a given function circuit output and an elliptic curve point, the function circuit input is equal to the corresponding elliptic curve point multiplier. The statement can be that the prover knows a private key for an address on a blockchain network.
