Functions

func EncodeDesc

func EncodeDesc(sc ScriptClass, amount int64, txVersion uint16, lockTime, expiry uint32) []byte

EncodeDesc encodes a description defining the parameters for a Decred coinjoin.

Types

type Blamer

type Blamer interface {
	Blame() []int
}

Blamer describes misbehaving peer IDs.

type Caller

type Caller interface {
	Call(ctx context.Context, method string, res interface{}, args ...interface{}) error
}

Caller performs a RPC method call.

type ScriptClass

type ScriptClass int
const (
	P2PKHv0 ScriptClass = iota
	P2SHv0
)

Recognized script classes

func DecodeDesc

func DecodeDesc(desc []byte) (sc ScriptClass, amount int64, txVersion uint16, lockTime, expiry uint32, err error)

DecodeDesc decodes a description defining the parameters for a compatible coinjoin.

func (ScriptClass) Match

func (sc ScriptClass) Match(script []byte, vers uint16) bool

type Tx

type Tx struct {
	Tx wire.MsgTx
	// contains filtered or unexported fields
}

Tx is a Decred CoinJoin transaction builder. It is intended for usage by CoinJoin servers, not clients.

func NewTx

func NewTx(caller Caller, sc ScriptClass, amount, feeRate int64, txVersion uint16,
	lockTime, expiry uint32) (*Tx, error)

func (*Tx) Confirm

func (t *Tx) Confirm(confirm interface{}, pid int) error

Confirm extracts the signatures from peer pid in confirm and adds them the receiver.

confirm must have type *Tx.

func (*Tx) Join

func (t *Tx) Join(unmixed []byte, pid int) error

Join adds the inputs and outputs of a transaction in wire encoding to t. Inputs and outputs are associated with a peer id for blame assignment.

func (*Tx) MarshalBinary

func (t *Tx) MarshalBinary() ([]byte, error)

MarshalBinary marshals the transaction in wire encoding.

func (*Tx) Mix

func (t *Tx) Mix(m []byte)

Mix adds an output with m as the PkScript. The output will use the builder's output value and script version.

func (*Tx) PublishMix

func (t *Tx) PublishMix(ctx context.Context) error

PublishMix publishes a transaction using the dcrd sendrawtransaction RPC.

func (*Tx) Report

func (t *Tx) Report() interface{}

Report returns an object that can be marshaled with reflection-based encoders such as encoding/json and encoding/gob. The object includes details about the current CoinJoin transaction.

func (*Tx) Shuffle

func (t *Tx) Shuffle()

Shuffle randomly shuffles the transaction inputs and outputs. Randomness is obtained from a cryptographically-seeded PRNG. Must only be used before signing.

func (*Tx) UnmarshalBinary

func (t *Tx) UnmarshalBinary(b []byte) error

UnmarshalBinary unmarshals the transaction in wire encoding.

func (*Tx) ValidateUnmixed

func (t *Tx) ValidateUnmixed(unmixed []byte, mcount int) error
