關於解釋 blockchain.info API 返回的問題

例如，當查看此輸出時，對於塊中第一筆交易中的“輸入”條目（即始終由新生成的硬幣組成）： "inputs":[{"sequence":4294967295,"witness":"01200000000000000000000000000000000000000000000000000000000000000000","script":"03046a0a046b03966062696e616e63652f626afabe6d6d5eab0f9044182c948a6cc6c4cfcc4c8df66f5839f34cbf36afff532d3eb0188e020000001e34c5f04e198bb203b9000000000000","index":0,"prev_out":{"tx_index":0,"value":0,"n":4294967295,"type":0,"spent":true,"script":"","spending_outpoints":[{"tx_index":6620159290300855,"n":0}]}}]

我想知道它是什麼意思"value":0,"n":4294967295。我試圖在頁面中查找數字 4294967295，但一無所獲。另外我懷疑“value”和“n”的值似乎是相反的。

這是使用 Blockstream.info API 的相同交易，顯示的是 Coinbase Tx，在我看來比 blockchain.info 更清晰的輸出。根據比特幣 Wiki，序列號通常設置為 0xFFFFFFFF（十進制：4294967295），除非交易的 lock_time > 0。
