Handshake Algorithm

Ethash is a Proof of Work (PoW) algorithm predominantly used in the Ethereum blockchain and other cryptocurrencies that are based on the Ethereum network. It relies heavily on memory for computations, as it is designed to be memory-intensive.

A variant of the SHA3 Hash, known as Keccak-256, Ethash improves mining efficiency by reducing difficulty. This algorithm is particularly effective for maintaining a decentralized network and is best suited for mining Ethereum-based cryptocurrencies, including ETC and ETH.
