  "doc": "Digest of the original Keccak-256 hash function (256 bits) as used by Ethereum. It differs from the standardized SHA3-256, which uses different padding. It is written as 64 hexadecimal digits. Other 256-bit digests (SHA-256, SHA3-256, BLAKE2b-256, BLAKE3 and Streebog-256) have the same length, so the value alone does not tell them apart: use the field name or context.",
