如何從原始交易中的輸入中提取地址

我需要幫助才能在離線模式下從“vin”獲取輸入地址。

我不知道<https://live.blockcypher.com/btc/decodetx/>是如何做到的。

原始交易範例：

交易編號：b0dd3d915a568c9d48e37b3fbfca58ae3276a5dba176fdf30f18af794310cc02

原始交易：

謝謝你。

下面應用的**bitcoin-exlporer (bx) 工具**尚不支持分析原始十六進制交易 (TX) 的 segwit 編碼部分。但是，鑑於上面提供的原始 TX 以及與兩個輸入 UTXO 關聯的兩個相關 TX，下面的 bx 命令可以離線分析結果。

然後需要檢查與以下內容相關的保留腳本，以確定它們是 P2PKH 還是 P2SH 地址類型：

1. 事務 ID f0fa97af6ba86096d9efcfea0bef4d6d146552bdf70e25b067dce1c1520d37b4 和索引 0

經檢查，兩種不同的產權負擔腳本均為 P2SH 形式：

1. 腳本“hash160 [49e282ad0605c1cb63ff45fc34b14357859e8d08] 相等”

2. 腳本“hash160 [70871ecb261f3df9a9d325b33ef6d8acb5074258] 相等”

兩個address_hash數據值的操作如下：

% 迴聲 49e282ad0605c1cb63ff45fc34b14357859e8d08 | bx base58check-encode -v 5 38Rgbmaxitveg1S8UNbWjwV5UMoBt3PtnG

如果特定地址是 P2PKH 形式，則將上述操作中的-v 5替換為。-v 0

順便說一句 - 根據對兩個 DER 編碼簽名的檢查並知道最後一個數據元素是腳本編碼的，看起來兩個贖回的 P2SH 輸入實際上都是 2 個多重簽名地址中的 2 個。
