트랜잭션 직렬화 코딩하기
지금까지 직렬화된 트랜잭션을 파싱했습니다. 이제 반대의 경우, 즉 주어진 트랜잭션을 직렬화
하는 방법을 살펴보겠습니다. 먼저
TxOut
클래스부터 시작합니다.
class TxOut:
...
def serialize(self):
➊
'''Returns the byte serialization of the transaction output'''
result = int_to_little_endian(self.amount, 8)
result += self.script_pubkey.serialize()
return result
➊
TxOut
객체를
bytes
형으로 직렬화합니다.
다음은
TxIn
을 직렬화합니다.
class TxIn:
...
def serialize(self):
'''Returns the byte serialization of the transaction input'''
result = self.prev_tx[::-1]
result += int_to_little_endian(self.prev_index, 4)
result += self.script_sig.serialize()
result += int_to_little_endian(self.sequence, 4)
return result
