  5. In cryptography, a zero-knowledge proof or zero-knowledge protocol is a method by which one party (the prover) can prove to another party (the verifier) that they know a value x, without conveying any information apart from the fact that they know the value x. The essence of a zero-knowledge proof is that it is trivial to prove that someone possesses knowledge of certain information by simply revealing it. The challenge is to justify such possession without revealing the.

A zero-knowledge proof is a unique method where a user can prove to another user that he/she knows an absolute value, without actually conveying any extra information. Here, the prover could prove that he knows the value z to the verifier without giving him any information other than the fact that he knows the value z for example is the case of Zero Knowledge Proofs (ZKP). ZKP is a crypto-graphic technique that can be used to hide information that is put into the ledger, while still allowing to perform validation of this data.
