操作對目前堆棧大小無效

根據 bip65 <https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki>

我可以使用 IF … ELSE … ENDIF 之類的表達式這是本文件中的範例腳本：

IF
   HASH160 <Hash160(encryption key)> EQUALVERIFY
   <publisher pubkey> CHECKSIG
ELSE
   <expiry time> CHECKLOCKTIMEVERIFY DROP
   <buyer pubkey> CHECKSIG
ENDIF

但是當我嘗試使用以下腳本進行交易時：

OP_IF 
   OP_SHA256 4bf5122f344554c53bde2ebb8cd2b7e3d1600ad631c385a5d7cce23c7785459a OP_EQUAL 
OP_ELSE 
   10 OP_CHECKLOCKTIMEVERIFY OP_DROP OP_SHA256 dbc1b4c900ffe48d575b5da5c638040125f65db0fe3e24494b76ea986457d986 OP_EQUAL
OP_ENDIF

我得到錯誤：

bitcoin-cli -testnet sendrawtransaction 020000000174c3e24cbc6f8a0633e55f055e1747127e91f5b6e1157fc059e1b700b777f4db000000000151ffffffff01c0d401000000000023a820dbc1b4c900ffe48d575b5da5c638040125f65db0fe3e24494b76ea986457d9868700000000
error code: -26
error message:

我的錯誤在哪裡？

附言

SHA256 從 1 -> 4bf5122f344554c53bde2ebb8cd2b7e3d1600ad631c385a5d7cce23c7785459a

SHA256 來自 2 -> dbc1b4c900ffe48d575b5da5c638040125f65db0fe3e24494b76ea986457d986

您的事務在其腳本中只有0x51(just OP_1)，OP_IF消耗1，OP_SHA256然後在空堆棧上操作，導致此錯誤。

就像 arubi 說的，你的 scriptSig 只是0x51：

$ bitcoin-cli decoderawtransaction 020000000174c3e24cbc6f8a0633e55f055e1747127e91f5b6e1157fc059e1b700b777f4db000000000151ffffffff01c0d401000000000023a820dbc1b4c900ffe48d575b5da5c638040125f65db0fe3e24494b76ea986457d9868700000000

       "hex": "a820dbc1b4c900ffe48d575b5da5c638040125f65db0fe3e24494b76ea986457d98687",
       "type": "nonstandard"
     }
   }
 ]
}

這意味著如果scriptPubKey您花費的輸入是：

OP_IF 
   OP_SHA256 4bf5122f344554c53bde2ebb8cd2b7e3d1600ad631c385a5d7cce23c7785459a OP_EQUAL 
OP_ELSE 
   10 OP_CHECKLOCKTIMEVERIFY OP_DROP OP_SHA256 dbc1b4c900ffe48d575b5da5c638040125f65db0fe3e24494b76ea986457d986 OP_EQUAL
OP_ENDIF

它將執行這個分支（因為棧頂元素為真）：

OP_IF 
   OP_SHA256 4bf5122f344554c53bde2ebb8cd2b7e3d1600ad631c385a5d7cce23c7785459a OP_EQUAL 

您還必須為該值提供任何散列值4bf5122f344554c53bde2ebb8cd2b7e3d1600ad631c385a5d7cce23c7785459a以使其成功返回。
