Scrypt is a proof-of-work hashing algorithm that uses the consensus. Its password-based security feature provides network security.

Scrypt mining is used by top blockchains and can be a safe alternative to Bitcoin's SHA256 algorithm. Miners can earn rewards by validating blocks of transactions using this method.

Colin Percival created this algorithm in 2009. He initially intended to use it as an online Tarsnap back-up service.

It was later popularized for its outstanding features. Scrypt's main goal is to make hardware attacks more difficult.
