zero knowledge proofs identity

A **zero-knowledge proof of identity** is a cryptographic method through which one party (the prover) can demonstrate to another party (the verifier) that they possess certain knowledge—typically, secret information that establishes their identity—without revealing the actual secret itself.

In this context:
- The **prover** proves they know a secret (like a password, private key, or other credentials).
- The **verifier** confirms the prover’s identity based only on the validity of the proof, not by learning the secret.

This approach is widely used in secure authentication systems, digital identity frameworks, and blockchain applications to ensure privacy and reduce the risk of credential exposure.
