数据显示，比特币挖矿难度的最新下调导致哈希率出现反弹。
根据最新的每周报告奥术研究 ，算力在挖矿难度创一年来最大降幅后回升。
这 ”挖矿算力 ”是衡量连接到比特币网络的计算能力总量的指标。
更高的指标值通常会导致区块链的性能更快，而单个机器的更大程度的去中心化会导致更强的安全性。
哈希率也可以被认为是个体矿工之间竞争的表现。因此，该指标的价值越大，矿工面临的竞争就越大。
比特币网络的一个特点是它试图保持恒定的“块生产率”（这基本上意味着它试图保持每天的交易量固定）。
然而，当加密货币的哈希率波动时，块率也会波动。例如，如果一些矿工与网络断开连接，散列交易的速度就会减慢，并且开采的区块会少于需要的区块。
为了抵消这一点，区块链所做的是减少“挖矿难度 ” 的网络使矿工发现更容易解决他们的计算难题和更接近所需速率的哈希交易。
现在，这是一张图表，显示了过去一年比特币 7 天平均挖矿哈希率的趋势：

正如您在上图中所看到的，比特币挖矿哈希率已经下降了一段时间，直到大约两周前。
由于这种持续的下降趋势，网络难度连续三次负调整，最近一次是一年前以来最大的一次负调整。
哈希率下降背后的原因是矿工的收益递减，这主要是由于今年 BTC 价格暴跌造成的。
但是由于难度已经显着下降，因此哈希率略有回升。这是因为较低的网络难度会为矿工带来更高的收入。
但目前出块率已经飙升到高于要求的水平，预计接下来的调整将再次给矿工带来更高的难度。
