與 coinb.in 部分簽署交易

我正在嘗試生成 2-of-2 多重簽名地址：

• pubkey1``privkey1在coinb.in上
• pubkey2和privkey2一個比特幣核心客戶端
• 我createmultisig 2 '''["<pubkey1>", "<pubkey2>']'''在核心上使用生成 2-of-2 多重簽名地址。

.

}

我將 0.00001BTC 轉移到 txid 20615db3dcda53ab1e780bb9f2c417c5ad2acfbd475d168b205caba3db401f1a 中的該地址，我 的目標是從多重簽名地址中花費這筆金額：

• 我在 bitcoincore 上創建了一個原始交易：

.

• 我嘗試在核心上簽署第二筆交易：

我究竟做錯了什麼？不幸的是，我無法指定pubkeyscript或redeemscrit到 coinb.in，所以這可能是簽名未驗證的原因嗎？

**注意：**當我在命令中指定兩個私鑰時，我可以在比特幣核心上成功簽署交易。

sign好吧，我設法通過在呼叫coinbin的方法之前手動修改javascript中的事務來解決這個問題。我已在此處送出了有關詳細資訊的問題。這就是我最終在 Javascript 中解決問題的方式（這是一種 hack，我只是為每個輸入指定了相同的兌換腳本，這適用於我的特定案例）：

var rawtx2 = "01000000021a1f40dba3ab5c208b165d47bdcf2aadc517c4f2b90b781eab53dadcb35d61200100000000ffffffff05ec447a886d8711db0d5f4cbf1f61956cf227c82c5594ee195bb179e86faa910100000000ffffffff0138c70000000000001976a91472a2a94468e42593656cc9803c7a48c1863fc3e588ac00000000";


(function partialSignMultisig(window) {
   var coinjs = window.coinjs;
   var wifkey = "<WIFKEYHERE>";
   var script = rawtx2;
   var redeemScript = "5221020150ce6954f0cdcc2c5d57cf249f25eab0eed23e39549c4f06bcb42a37f308ce2102224aca2849ddad9c663c0bcfdac5ce3ca06f784ac8eca83404a4ea4ac61dbe7d52ae";

   var tx = coinjs.transaction();
   var t = tx.deserialize(script);

       // Manually specify scripts for inputs ..
   for (var i = 0; i < t.ins.length; i++) {
       t.ins[i].script = coinjs.script(redeemScript);
   }

   var signed = t.sign(wifkey);
   console.log( signed );


})(window);
