BlockChain data structures

the block header

data BlockHeader

The header of a block

Constructors

BlockHeader

Fields

• _blkBlockVersion :: !Word32

  block version (currently 1 or 2)

• _blkPrevBlock :: !Hash256

  hash of the previous block

• _blkMerkleRoot :: !Hash256

  merkle root of the transaction tree

• _blkTimeStamp :: !UnixTimeStamp

  timestamp of the block

• _blkDifficulty :: !Word32

  the difficulty (see Bitcoin.Protocol.Difficulty)

• _blkNonce :: !Word32

  the nonce

• _blkBlockHash :: Hash256

  the hash of this block. Note: the hash is not actually stored in the blockchain; but it is computed when the block is loaded
