data Coinbase #

Data type representing the coinbase transaction of a Block. Coinbase transactions are special types of transactions which are created by miners when they find a new block. Coinbase transactions have no inputs. They have outputs sending the newly generated bitcoins together with all the block's fees to a bitcoin address (usually the miners address). Data can be embedded in a Coinbase transaction which can be chosen by the miner of a block. This data also typically contains some randomness which is used, together with the nonce, to find a partial hash collision on the block's hash.

Constructors

Coinbase

Fields

_cbVersion :: Word32
Transaction data format version.
_cbPrevOutput :: OutPoint
Previous outpoint. This is ignored for coinbase transactions but preserved for computing the correct txid.
_cbData :: ByteString
Data embedded inside the coinbase transaction.
_cbInSequence :: Word32
Transaction sequence number. This is ignored for coinbase transactions but preserved for computing the correct txid.
_cbOut :: [TransactionOut]
List of transaction outputs.
_cbLockTime :: Word32
The block number of timestamp at which this transaction is locked.
