The truncated header doesn't contain the mixHash (H m) or header nonce (H n). Using below table, you can check how profitable it is to mine selected altcoins in comparison to ethereum classic. According to this, NIST changed the padding to SHA3-256 (M) KECCAK 512 (M 01, 256). ![]() It should be noted that it does not follow the FIPS-202 based standard (a.k.a SHA-3), which was finalized in August 2015. The Hashimoto function requires the truncated RPL-encoded header of the current block being mined, which itself contains the parentHash (H p in the Yellow Paper), together with the mining nonce. 2 Answers Sorted by: 167 Ethereum uses KECCAK-256. I would assume that it is an RLP-encoded value of the previous block hash, ommer hashes, nonce, state trie root hash etc. Thanks, I have found this answer before but I want to know the exact 'function' to calculate the mixhash and how to generate it with, say, header + nonce, etc. While hashimoto_full(full_size, dataset, header, nonce) > target: ![]() ![]() # zero-pad target to compare with hash on the same digit The main Hashimoto mining loop is defined in the following Python pseudo-code (found here): def mine(full_size, dataset, header, difficulty):
