Bitcoin block header structure
5 rows · WebBlock headers are serialized in the 80-byte format described below and then hashed as part of Bitcoin’s proof-of-work algorithm, making the serialized header format part of the consensus rules. The block version number indicates which set of block validation rules to follow. See the list of block versions below.
