Zero-Knowledge Proof (ZKP)

Zero-Knowledge Proof (ZKP) is a cryptographic technique that allows one party (the prover) to prove to another party (the verifier) that a statement is true without revealing any additional information. In other words, ZKP enables a party to verify the authenticity of data or transactions without exposing the underlying information. This method is particularly useful in enhancing privacy and security in blockchain networks and other cryptographic systems. ZKPs are widely used in privacy-focused cryptocurrencies like Zcash (ZEC), where they help protect transaction details such as sender, receiver, and transaction amount, while still ensuring that the transaction is valid. The most common types of ZKP are "interactive" and "non-interactive," with zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge) being a prominent example of non-interactive ZKP. Zero-knowledge proofs are critical in maintaining privacy while ensuring the integrity and accuracy of data in decentralized networks.
