args 字节布局args byte layout
tx_hash32B
index4B
- tx_hash 32B OutPoint.tx_hashOutPoint.tx_hash 被某个输入消耗consumed by an input (7)
- index 4B OutPoint.index u32 LEOutPoint.index u32 LE 同上same (7)
限制Constraints
- args ≥ 36 字节≥ 36 bytes (4)
- inputs：: 某个输入的 previous_output = args 中的 OutPoint（该 OutPoint 只能花一次，故锁只能用一次）some input's previous_output = the OutPoint in args (it can be spent only once, so the lock is single-use) (7)
