bitcoinrpc.authproxy.JSONRPCException：-26:16：bad-txns-in-belowout

當我使用sendrawtransaction. 我想要做的就是將這個文件翻譯成 Python 程式碼，我已經搜尋了一段時間，但是任何人都可以解釋這個錯誤嗎？Bitcore Multisig - bad-txns-in-belowout和比特幣核心“bad-txns-in-belowout”無法讓我清楚。並且所有異常回溯列表如下：

回溯（最近一次通話最後）：

文件“multisign.py”，第 137 行，在 print(ms.go()) 文件“multisign.py”，第 128 行，在 go ret = self.rpc.sendrawtransaction(last_hex) 文件“/Users/frank/venv/ bitcoin/lib/python2.7/site-packages/bitcoinrpc/authproxy.py”，第 141 行，呼叫中 raise JSONRPCException(response[’error’]) bitcoinrpc.authproxy.JSONRPCException: -26: 16: bad-txns-in -低於

該錯誤意味著您正在嘗試花費比您投入更多的錢。換句話說，value in < value out. 您需要添加更多輸入，以使總輸入值超過總輸出值。

您需要從您嘗試發送的地址收到的先前交易中獲得未使用的輸出。查看來自 blockchain.info api 的listreceivedbyaddress。
