Zero-Knowledge Proof (ZKP)

A Zero-Knowledge Proof (ZKP) is a cryptographic method that allows one party (the prover) to prove to another party (the verifier) that a statement is true without revealing any information beyond the validity of the statement itself. In simple terms, a user can prove that they hold a Bitcoin without revealing their signature and public address.

The most significant benefits of the ZK protocol are that people do not have to reveal personal information for validation, and no complex encryption is involved.
