比特币 (BTC) 矿工投降，算力从历史最高点暴跌 8%，目标难度再创新低

“挖矿算力”是指跟踪矿工当前连接到比特币区块链的算力总量的指标。

The Bitcoin (BTC) mining hashrate has continued its decline as the cryptocurrency’s price faced a setback in its recovery.

随着加密货币价格复苏受挫，比特币（BTC）挖矿算力持续下降。

7-Day Average Bitcoin Mining Hashrate Dropped Over 8% Since All-Time High

比特币挖矿 7 天平均算力自历史最高点以来下降了 8% 以上

The “mining hashrate” is a metric that measures the total amount of computing power currently connected to the Bitcoin blockchain by miners. This indicator is generally used to gauge the present state of BTC miners.

“挖矿算力”是衡量矿工当前连接到比特币区块链的计算能力总量的指标。该指标一般用于衡量BTC矿工的现状。

When the indicator’s value increases, it means new miners are joining the network and/or old ones are expanding their operations. Such a trend suggests that these chain validators are finding the network attractive.

当该指标的值增加时，意味着新的矿工正在加入网络和/或旧的矿工正在扩大其业务。这种趋势表明这些链验证者发现该网络具有吸引力。

On the other hand, a decrease in the metric suggests that some miners are choosing to disconnect from the network, possibly because they no longer find BTC mining to be profitable.

另一方面，该指标的下降表明一些矿工选择断开与网络的连接，可能是因为他们不再发现 BTC 挖矿有利可图。

Now, here's a chart that shows the 7-day average Bitcoin mining hashrate's trend over the past year:

现在，这是一张图表，显示了过去一年 7 天平均比特币挖矿算力的趋势：

The 7-day average Bitcoin mining hashrate had surged to a new all-time high (ATH) by the end of last month, but since then, it observed a constant decline.

到上月底，比特币挖矿7天平均算力已飙升至历史新高（ATH），但此后持续下降。

The ATH was reached as the BTC price rallied up, and the drawdown in the metric coincided with a period of bearish momentum for the cryptocurrency. This close relationship is because miner revenue is heavily tied to the asset's price.

当 BTC 价格上涨时，达到了 ATH，而该指标的下跌恰逢加密货币的看跌势头时期。这种密切的关系是因为矿工的收入与资产的价格密切相关。

These chain validators earn income from two sources, transaction fees and block subsidy, with the latter of the two being the more dominant source historically.

这些链验证者的收入有两个来源：交易费和区块补贴，历史上后者是更主要的来源。

The block subsidy, which miners receive as a reward for solving blocks on the network, is paid out at a fixed BTC value and also at a more or less fixed time interval. This leaves the only variable related to it as the USD price of the cryptocurrency.

区块补贴是矿工因解决网络上的区块而获得的奖励，以固定的 BTC 价值和或多或少固定的时间间隔支付。这使得与之相关的唯一变量是加密货币的美元价格。

When the asset's value goes up, so does that of these rewards, and hence, that of the miner revenue. As such, miners tend to follow the coin's trajectory when it comes to adding or removing hashrate.

当资产价值上涨时，这些奖励也会上涨，矿工收入也会上涨。因此，矿工在添加或删除算力时倾向于遵循代币的轨迹。

Interestingly, though, while Bitcoin did recover above the $62,000 level earlier, the hashrate didn't see any reversal, perhaps because the miners didn't think the increase would last. They may have been proven right, as the asset did erase some of its recovery over the past day.

不过有趣的是，虽然比特币早些时候确实恢复到了 62,000 美元以上的水平，但算力并没有出现任何逆转，也许是因为矿工认为这种上涨不会持续下去。他们可能被证明是正确的，因为该资产在过去一天确实抹去了部分复苏的势头。

One consequence of the constant mining hashrate drawdown is that the network is set to see a negative difficulty change in its next scheduled adjustment.

挖矿算力不断下降的一个后果是，网络将在下一次计划调整中看到负面的难度变化。

The difficulty is a feature of the Bitcoin blockchain that governs how difficult miners will find it to mine on the network. The existence of the difficulty is what allows for the block subsidy to be paid out at fixed intervals.

难度是比特币区块链的一个特征，它决定了矿工在网络上挖矿的难度。困难的存在使得整笔补贴能够定期支付。

When the miners add hashrate, they naturally become faster at mining, and thus, they churn out blocks at a faster rate. To counteract this, the network ups the difficulty just enough to slow the miners down to the standard 10 minutes per block rate.

当矿工增加算力时，他们的挖矿速度自然会变得更快，因此他们会以更快的速度生产出区块。为了解决这个问题，网络将难度提高到足以将矿工的速度降低到标准的每块 10 分钟的速度。

As the miners have been decreasing their hashrate recently, the block time has been slower than usual. The Bitcoin blockchain will now decrease the difficulty by over 4% to make things easier for the validators.

由于矿工最近降低了算力，出块时间比平时慢。比特币区块链现在将难度降低 4% 以上，以使验证者的工作变得更容易。
