Keccak-256

Keccak-256 is a cryptographic hash function used in blockchain networks such as Ethereum. It takes an input of any size and produces a fixed-size output of 256 bits. Keccak-256 is known for its resistance against collision and pre-image attacks, making it suitable for various cryptographic applications, including digital signatures, data integrity verification, and proof-of-work algorithms. It is widely used in blockchain networks to securely generate unique hash values that uniquely identify data blocks, transactions, and other elements of the blockchain.
