数据显示，近期比特币算力下降趋势导致挖矿难度在过去一年中出现最大的负向调整。
根据最新的每周报告奥术研究 ，周四将观察到自 2021 年 7 月以来最大的挖矿难度下降。
这 ”挖矿算力 ”是衡量连接到比特币区块链的计算能力总量的指标。
该指标的值越高，通常网络性能越好，哈希率越去中心化，网络安全性越强。
哈希率也代表了连接到链上的不同矿工之间的竞争。因此，当指标呈上升趋势时，“挖矿难度 ”也涨。
发生这种情况是因为比特币网络必须保持恒定的块发现率。由于更多的挖矿能力意味着矿工现在可以更快地对交易进行哈希处理，因此出块率也会上升。为了补偿它，网络增加了难度。

块率已降至每小时 5.53 个，大大低于网络要求的每小时 6 个值。正因为如此，在接下来的调整中，难度预计将下降近6%。
在撰写本文时，比特币的价格 浮动在 2.36 万美元左右，在过去 7 天内上涨了 20%。在过去的一个月里，加密货币的价值上涨了 15%。
