decode Source

Arguments

:: HexString	The hexadecimal representation of the transaction
-> Transaction	The decoded `Transaction` object

Decodes a hex representation of a transaction into a Transaction object.

encode Source

Arguments

:: Transaction	The `Transaction` we would like to encode to hex
-> HexString	The hexadecimal representation of the transaction

Encodes a Transaction object into a hex representation.

transactionId :: Transaction -> TransactionId Source

Calculates the transaction id of a Transaction as a TransactionId so it can be used in RPC interfaces.

TxnPubKey	JSON of "pubkey" received.
TxnPubKeyHash	JSON of "pubkeyhash" received.
TxnScriptHash	JSON of "scripthash" received.

data OutPoint Source

The OutPoint is used inside a transaction input to reference the previous transaction output that it is spending.

Constructors

OutPoint
Fields _outPointHash :: TransactionHash The hash of the referenced transaction. _outPointIndex :: Word32 The position of the specific output in the transaction. The first output position is 0.

outPointIndex :: Lens' OutPoint Word32 Source

outPointHash :: Lens' OutPoint TransactionHash Source

data TransactionIn Source

Data type representing a transaction input.

Constructors

TransactionIn

Fields

_prevOutput :: OutPoint: Reference the previous transaction output (hash + position)
_scriptInput :: Script: Script providing the requirements of the previous transaction output to spend those coins.
_txInSequence :: Word32: Transaction version as defined by the sender of the transaction. The intended use is for replacing transactions with new information before the transaction is included in a block.

data Transaction Source

Data type representing a bitcoin transaction

Constructors

data Coinbase Source

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.
