Understanding ZKPs
ZKPs are like a magic trick in cryptography. They let one person prove to another that they know something or that something is true, without actually revealing what that thing is or any extra details about it. It’s a way to share secrets without giving away the whole story. This concept is essential in preserving privacy in various cryptographic applications, as it enables secure authentication and verification without disclosing sensitive information.
A ZKP has three main properties:
- Completeness: If the statement is true and both the prover and verifier follow the protocol, the verifier will be convinced that the statement is true.
- Soundness: If the statement is false, a dishonest prover cannot convince the verifier that the statement is true, except with negligible probability.
- Zero-knowledge: If the statement is true, the verifier learns nothing beyond the fact that the statement is true. In other words, the verifier cannot extract...
