트랜잭션 검증과 생성
193
비트코인 코딩에서 가장 까다로운 부분 중 하나는 트랜잭션 검증과 생성에 관한 부분입니다.
이번에는 트랜잭션을 검증하고 생성하는 방법을 단계적으로 설명합니다. 이 장 마지막에서는
테스트넷에서 트랜잭션을 생성하고 실제로 전파시켜보겠습니다.
7.1
트랜잭션 검증
트랜잭션을 수신한 후 모든 노드는 트랜잭션이 네트워크 규칙에 부합되도록 만들어졌는지 확
인합니다. 이 과정을 트랜잭션 검증이라고 합니다. 다음은 검증을 위해 노드가 확인하는 주요
항목입니다.
1
. 트랜잭션의 입력이 가리키는 비트코인이 존재하고 사용 가능한가?
2
. 입력 비트코인의 합은 출력 비트코인의 합보다 크거나 같은가?
3
. 입력의 해제 스크립트는 참조하는 트랜잭션 출력의 잠금 스크립트를 해제하는가?
1
번 항목은 이중 지불 방지 항목입니다. 입력의 비트코인이 이미 사용되었다면 (즉 블록체인
에 기록되었다면 ) 다시 사용될 수 없습니다.
2
번 항목은 새 비트코인이 만들어지지 않도록 합니다 (코인베이스 트랜잭션이라고 하는 특별
한 트랜잭션의 경우는 예외입니다.

장 참고 ).
