Zero-knowledge proof

A zero-knowledge proof is an important cryptographic primitive used to achieve anonymity in the implementation of Zcash. It is a method where one party, say, Alice, who owns some secret information, can prove to the other party, Bob, that she owns the information without actually revealing it. Every zero-knowledge proof will have two parties, a prover, and a verifier. The prover will always possess knowledge that is kept secret, and the verifier will verify the statement of the prover. The prover should always make use of the secret knowledge while creating the proof, which implies that the verifier should not be able to reproduce the proof to other parties without the secret knowledge. Whenever a prover creates a zero-knowledge ...
