從原始事務解碼的 JSON 中的 hex 和 asm 欄位值是什麼？

我使用命令行bitcoin-cli decoderawtransaction <hex-value>並返回了 JSON 輸出（見下文）。hex但是，我注意到有些asm欄位本身就是十六進制值（有時）。我認為這些是可以進一步解碼的元數據。那正確嗎？

是否有更多關於為這 2 個欄位（或更多）傳回的 JSON 的結構和含義的文件？

我讀了這篇SO 文章，其中提到了這篇過時的文章。

另外，我在比特幣區塊瀏覽器上檢查了交易。他們似乎有一些我在 JSON 中看不到的元數據（例如接收時間、確認、中繼 ip 等……）。這些價值觀從何而來？

此外，我使用https://blockchain.info/decode-tx解碼了原始交易並得到了一些不同的東西。

asm指腳本的反序列化形式，將眾所周知的標記解析為腳本標記。

hex只是十六進制編碼中腳本的序列化形式。

如果你仔細比較它們，它們本質上是等價的。

例如：

OP_DUP OP_HASH160 f9d49c5cf3e120ad1be60b67d868603a8fc945d2 OP_EQUALVERIFY OP_CHECKSIG

76 a9 14 f9d49c5cf3e120ad1be60b67d868603a8fc945d2 88 ac

76是OP_DUP

14是要壓入堆棧的字節數。

等等…
