多重簽名交易 - 驗證第一個簽名是否有效？

使用位於此處的 Gavin Anderson 的 TwoOfThree.sh Gist： https ://gist.github.com/gavinandresen/3966071

在執行第二個 signrawtransaction 之前，是否可以從已知的公鑰驗證第一個“部分”signrawtransaction 是否有效？我的目標是盡可能確定交易將在發送之前被網路接受。在這種情況下，我已經知道相關的多重簽名地址可以使用比特幣，並且交易中包含了適當的交易費用。

這兩個步驟如下。幫助表示讚賞！

據我所知，比特幣沒有內置功能可以獨立檢查每個輸入中的簽名。要麼所有簽名都正確（因此顯示{complete: true}），要麼至少有一個無符號/無效/輸入值不加到輸出值中（因此顯示{complete: false}）。

程序如下：

1. {txid, vout}從 UTXO 集中檢索引用的輸出或檢索txid並僅獲取適當的輸出。
2. 檢查value是您期望的（如果您完全關心價值）並獲得scriptPubKey.
3. 執行 current-input scriptSig，然後使用結果堆棧執行 previous-output scriptPubKey。

如果結果堆棧頂部不為零（即 is TRUE），則輸入正確簽名。
