Types

type TXInput

type TXInput struct {
	Txid      []byte
	Vout      int
	Signature []byte
	PubKey    []byte
}

TXInput represents a transaction input

func (*TXInput) UsesKey

func (in *TXInput) UsesKey(pubKeyHash []byte) bool

UsesKey checks whether the address initiated the transaction

type TXOutput

type TXOutput struct {
	Value      int
	PubKeyHash []byte
}

TXOutput represents a transaction output

func NewTXOutput

func NewTXOutput(value int, address string) *TXOutput

NewTXOutput create a new TXOutput

func (*TXOutput) IsLockedWithKey

func (out *TXOutput) IsLockedWithKey(pubKeyHash []byte) bool

IsLockedWithKey checks if the output can be used by the owner of the pubkey

func (*TXOutput) Lock

func (out *TXOutput) Lock(address []byte)

Lock signs the output

type TXOutputs

type TXOutputs struct {
	Outputs []TXOutput
}

TXOutputs collects TXOutput

func DeserializeOutputs

func DeserializeOutputs(data []byte) TXOutputs

DeserializeOutputs deserializes TXOutputs

func (TXOutputs) Serialize

func (outs TXOutputs) Serialize() []byte

Serialize serializes TXOutputs

type Transaction

type Transaction struct {
	ID   []byte
	Vin  []TXInput
