The Cryptographic Hash Functions That Secure Bitcoin (Part 2)
Ethereum does not use NIST Standard SHA-3, but Keccak, which is the original algorithm presented to NIST.
NIST, after some modifications, such as an increase in the number of rounds and simpler message padding, standardized Keccak as SHA-3.
