  • @Denis, the same hash that was used by transaction creator when he signed it. – amaclin Oct 31 '17 at 17:35
  • @amaclin but block miner is not creator of transaction – Denis Leonov Oct 31 '17 at 17:43
  • @Denis, yes, but the process of calculating the hash is the same – amaclin Oct 31 '17 at 18:43

I think that the hash function used is sha256d, a non-standard function obtained by hashing with sha256 twice (first hash the data, obtain 256-byte digest, then re-hash the digest).
