【问题描述】：

我正在尝试确定比特币区块链中的交易是否已被确认。我已经使用以下 URL 从 blockchain.info 访问了交易的 JSON 表示：https://blockchain.info/tx/62f9419e56ac1b628840aaf52307867f9856d7a52b3c1d945a9938a3021cbf2c?show_adv=false&format=json

我在响应中找不到任何表明它有多少确认的信息...

【参考方案1】：

比特币上的“确认”概念本质上是指自从包含交易的区块以来已经生成了多少个区块。换句话说，你必须发出另一个请求来获取当前的网络块计数（http://blockchain.info/q/getblockcount），然后确认计数变为current_block_count - transaction_block_height + 1。请注意，block_height 仅在此后至少生成一个块时才会出现在响应中（即新交易甚至可能不包含该元素）。

【讨论】：

然后我如何确定这个 TX 是否不是双花？基本上，我有 TX 和块。但是如果我那么，2小时后，只计算当前区块，那并不意味着有任何骗局，并且这笔交易确实被确认了

据我了解，这是一种概率方法（足够多的块 => 假冒的可能性几乎为零），但我远非该主题的专家，因此我将向您介绍 Google :-) 话虽如此，我认为您的评论与“我如何......”与“它是如何工作的？”无关。
