Method WriteWitnessCommitmentTo

protocol/bc/tx.go:260–272

WriteWitnessCommitmentTo writes the "Transaction Witness Commitment" to w, consisting of the version, runlimit, and program in a tuple, encoded according to standard txvm convention, hashed together with the txid. The only errors returned are those from w.

(w io.Writer)

//
// The only errors returned are those from w.
func (tx *Tx) WriteWitnessCommitmentTo(w io.Writer) (int, error) {
	// See $I10R/docs/future/protocol/specifications/blockchain.md#transaction-witness-commitment
	// for the definition of the transaction witness commitment.
	n, err := tx.ID.WriteTo(w)
	if err != nil {
		return int(n), err
	}
	n2, err := tx.writeWitnessHashTo(w)
	if err != nil {
		return int(n) + n2, err
	}
	return int(n) + n2, nil
}
