從 pubkey scriptPubKey 獲取地址

鑑於這address是一個“方便”欄位，因此在許多事務中預設不提供它是有道理的。但是，似乎可以從中提取address``hex. 我想知道我是否可以從bitcoin客戶端應用程序（例如，bitcoin-qt）中獲取此地址，最好是通過 REST API。

我正在查看的一個範例塊是高度為 100 的塊：

       }
   ]
}

並非所有 scriptPubKeys 都對應一個地址。該address欄位是為那些這樣做的人提供的，而對於那些不這樣做的人則省略。您的範例包含一個沒有相應地址的 P2PK scriptPubKey。

一些區塊鏈瀏覽器可能會從 P2PK 輸出中提取公鑰併計算相應的地址，但這在技術上是不正確的。這樣的地址將產生 P2PKH scriptPubKey，而不是 P2PK。
