What is Zero Knowledge Proof?
Zero Knowledge Proof (ZKP) is a cryptographic technique that allows one party to prove to another party that they know something without revealing any information about what it is. It works by allowing the prover to demonstrate knowledge of some secret data, such as a password or private key, without actually disclosing the data itself. This makes ZKP an important tool for protecting sensitive information and ensuring privacy in digital transactions.
The concept behind Zero Knowledge Proofs was first proposed in 1985 by cryptographers Shafi Goldwasser, Silvio Micali and Charles Rackoff. Since then, many variations have been developed with different levels of security and complexity. In general, these proofs involve two parties: the verifier who wants to be sure that the prover knows certain facts; and the prover who must convince the verifier without giving away any details about those facts. The process involves creating mathematical puzzles which can only be solved if you possess certain knowledge or secrets – this way both parties are assured of each other’s trustworthiness while still maintaining their privacy.
