Zero-knowledge proofs (ZKPs), a groundbreaking concept in blockchain technology and computer science, allow a 'prover' (often referred to as 'Peggy') to affirm the truth of a statement to a 'verifier' without divulging any extra data. This ensures the privacy of users' transactions. This interactive proof system is a fundamental component of many cryptographic protocols, including those in cryptocurrencies like Bitcoin and Ethereum. The interaction between Peggy and the verifier guarantees the integrity of the proof, while the 'trusted setup' secures its authenticity. ZKPs are not merely theoretical; they are actively employed in blockchain transactions, enhancing the security and privacy of users' data. This category offers a comprehensive understanding of zero-knowledge proofs, their types, and their practical applications in safeguarding crypto transactions.
