對於輸入中引用的前一個交易,txid:7957a35fe64f80d234d76d83a2a8f1a0d8149a41d81de548f0a65a8a999f6f18,
用同樣的getrawtransaction和decoderawtransaction得到解碼後的該交易,獲取其UTXO:
"vout": [
{
"value": 0.10000000,
"scriptPubKey": "OP_DUP OP_HASH160 7f9b1a7fb68d60c536c2fd8aeaa53a8f3cc025a8 OP_EQUALVERIFY OP_CHECKSIG"
}
]
檢視Script,得知OP_HASH160 就是 The input is hashed twice: first with SHA-256 and then with RIPEMD-160,即先進行SHA-256雜湊,再進行RIPEMD-160雜湊。
