Synopsis

Documentation

decode #

Arguments

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

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

encode #

Arguments

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

Encodes a Block object into a hex representation.

headerHash :: Block -> HexString #

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

data BlockHeader #

Data type recording information on a Block. The hash of a block is defined as the hash of this data structure. The block mining process involves finding a partial hash collision by varying the nonce in the BlockHeader and/or additional randomness in the Coinbase of this Block. Variations in the Coinbase will result in different merkle roots in the BlockHeader.

Constructors

BlockHeader

Fields

_blockVersion :: Word32
Block version information, based on the version of the software creating this block.
_prevBlock :: BlockHash
Hash of the previous block (parent) referenced by this block.
_merkleRoot :: Word256
Root of the merkle tree of all transactions pertaining to this block.
_blockTimestamp :: Word32
Unix timestamp recording when this block was created
_blockBits :: Word32
The difficulty target being used for this block
_bhNonce :: Word32
A random nonce used to generate this block. Additional randomness is included in the coinbase transaction of this block.
