Trading Notes | Hash Functions
① A hash function converts data of any length into a fixed-length output. This output is called a hash value, or digest.
② Ethereum uses Keccak-256. Keccak-256 differs from the later standardized SHA3-256 in its padding rules, so they produce different results.
③ Don’t confuse a transaction hash with a private key: transaction hashes can be public, but private keys and seed phrases must never be shared.
