Functions

func AppendTxOutputToTx

func AppendTxOutputToTx(tx *TransactionType, txo *TxOutputType)

func SerializeForSeal

func SerializeForSeal(tx *TransactionType) []byte

SearalizeForSeal searializes into bytes the fields that will be hashed for the mining seal.

func SerializeTransaction

func SerializeTransaction(tx *TransactionType) []byte

SearalizeTransaction searializes into bytes the fields that will be hashed the hash of the block. This is the hash that the next block will use to point to this block and the hash that this block will be saved as.

func SerializeTransactionInput

func SerializeTransactionInput(buf *bytes.Buffer, inp *TxInputType)

func SerializeTransactionOutput

func SerializeTransactionOutput(buf *bytes.Buffer, out *TxOutputType)

Types

type TransactionType

type TransactionType struct {
	TxOffset       int               // The position of this in the block.
	Input          []TxInputType     // Set of inputs to a transaction
	Output         []TxOutputType    // Set of outputs to a tranaction
	SCOwnerAccount addr.AddressType  // Used in HW 6 - Smart Contracts - Owner of Contract
	SCAddress      addr.AddressType  // Used in HW 6 - Smart Contracts - Address of Contract
	SCOutputData   string            // Used in HW 6 - Smart Contracts - Output data from contract
	Account        addr.AddressType  //
	Signature      lib.SignatureType //	Used in HW 5 - Signature that this is a valid tranaction for this account
	Message        string            //	Used in HW 5 - Message (hash of original) that signature signs for
	Comment        string            //
}

func NewEmptyTx

func NewEmptyTx(memo string, passedAcct addr.AddressType) *TransactionType

type TxInputType

type TxInputType struct {
	BlockNo     int // Which block is this from
	TxOffset    int // The transaction in the block. In the block[BlockHash].Tx[TxOffset]
	TxOutputPos int // Position of the output in the transaction. In the  block[BlockHash].Tx[TxOffset].Output[TxOutptuPos]
	Amount      int // Value
}

func CreateTxInputsFromOldOutputs

func CreateTxInputsFromOldOutputs(oldOutput []*TxOutputType) (txIn []TxInputType, err error)

type TxOutputType

type TxOutputType struct {
	BlockNo     int              // Which block is this in
	TxOffset    int              // Which transaction in this block.  block[this].Tx[TxOffset]
	TxOutputPos int              // Position of the output in this block. In the  block[this].Tx[TxOffset].Output[TxOutptuPos]
	Account     addr.AddressType // Acctount funds go to (If this is ""chagne"" then this is the same as TransactionType.Account
	Amount      int              // Amoutn to go to accoutn
