示例1: EstFee
// EstFee gives a fee estimate based on a tx and a sat/Byte target.
// The TX should have all outputs, including the change address already
// populated (with potentially 0 amount. Also it should have all inputs
// populated, but inputs don't need to have sigscripts or witnesses
// (it'll guess the sizes of sigs/wits that arent' filled in).
func EstFee(otx *wire.MsgTx, spB int64) int64 {
mtsig := make([]byte, 72)
mtpub := make([]byte, 33)
tx := otx.Copy()
// iterate through txins, replacing subscript sigscripts with noise
// sigs or witnesses
for _, txin := range tx.TxIn {
// check wpkh
if len(txin.SignatureScript) == 22 &&
txin.SignatureScript[0] == 0x00 && txin.SignatureScript[1] == 0x14 {
txin.SignatureScript = nil
txin.Witness = make([][]byte, 2)
txin.Witness[0] = mtsig
