是否有任何 python 庫可用於在輸出中解碼腳本

例如像這樣解碼 ScriptPubKey

4104678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5fac

像這樣的一些數據

{
"result": {
   "asm": "04678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5f OP_CHECKSIG",
   "reqSigs": 1,
   "type": "pubkey",
   "addresses": [
       "1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa"
   ],
   "p2sh": "3DjjKyU38gSfuVxajV43MUy4vHkg1JVL7T"
},
"error": null,
"id": null
}

一般來說，類似於 decodescript rpc 中的函式。

我剛剛將它添加到我的玩具庫中。

>>> from btctools import decode_scriptpubkey
>>> decode_scriptpubkey('76a914b3c2dc3a7f68a024a5d2ee9d4012dca1134dea8588ac')
{'address': '1HPVPU3xHMPcxmgdP9puPbnDcHDV5JhURh',
'asm': 'OP_DUP OP_HASH160 b3c2dc3a7f68a024a5d2ee9d4012dca1134dea85 OP_EQUALVERIFY OP_CHECKSIG',
'hex': '76a914b3c2dc3a7f68a024a5d2ee9d4012dca1134dea8588ac',
'type': 'P2PKH'}

已解決並將程式碼保存在此處。 <https://github.com/keviny/bitcoin-block-parser>

在https://en.bitcoin.it/wiki/Script中可以找到許多詳細資訊。

在交易輸出中解碼 ScriptPubKey 的程式碼：

   self.pubkey = blockchain.read(self.script_len)
   self.addr = "UNKNOWN"
   self.decode_scriptpubkey(self.pubkey)

 def to_string(self):
   sb = []
   sb.append("Value: %d" % self.value + " Satoshi")
   sb.append("Script Len: %d" % self.script_len)
   sb.append("ScriptPubkey: %s" % self.addr)
   sb.append("Addr: %s" % self.addr)
   return sb
