比特幣 (BTC) 礦工投降，算力從歷史最高點暴跌 8%，目標難度再創新低

「挖礦算力」是指追蹤礦工目前連接到比特幣區塊鏈的算力總量的指標。

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

隨著加密貨幣價格復甦受挫，比特幣（BTC）挖礦算力持續下降。

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

比特幣挖礦 7 天平均算力自歷史最高點以來下降了 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.

「挖礦算力」是衡量礦工目前連接到比特幣區塊鏈的運算能力總量的指標。此指標一般用於衡量BTC礦工的現況。

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.

當該指標的值增加時，意味著新的礦工正在加入網路和/或舊的礦工正在擴大其業務。這種趨勢表明這些鏈驗證者發現該網路具有吸引力。

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，該指標的下降表明一些礦工選擇斷開與網路的連接，可能是因為他們不再發現 BTC 挖礦有利可圖。

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

現在，這是一張圖表，顯示了過去一年 7 天平均比特幣挖礦算力的趨勢：

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，比特幣挖礦7天平均算力已飆升至歷史新高（ATH），但此後持續下降。

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.

當 BTC 價格上漲時，達到了 ATH，而該指標的下跌恰逢加密貨幣的看跌勢頭時期。這種密切的關係是因為礦工的收入與資產的價格密切相關。

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.

這些鏈驗證者的收入有兩個來源：交易費和區塊補貼，歷史上後者是更主要的來源。

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.

區塊補貼是礦工因解決網路上的區塊而獲得的獎勵，以固定的 BTC 價值和或多或少固定的時間間隔支付。這使得與之相關的唯一變數是加密貨幣的美元價格。

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.

當資產價值上漲時，這些獎勵也會上漲，礦工收入也會上漲。因此，礦工在添加或刪除算力時傾向於遵循代幣的軌跡。

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.

不過有趣的是，雖然比特幣早些時候確實恢復到了 62,000 美元以上的水平，但算力並沒有出現任何逆轉，也許是因為礦工認為這種上漲不會持續下去。他們可能被證明是正確的，因為該資產在過去一天確實抹去了部分復甦的勢頭。

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.

挖礦算力不斷下降的一個後果是，網路將在下一次計畫調整中看到負面的難度變化。

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.

難度是比特幣區塊鏈的一個特徵，它決定了礦工在網路上挖礦的難度。困難的存在使得整筆補貼能夠定期支付。

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.

當礦工增加算力時，他們的挖礦速度自然會變得更快，因此他們會以更快的速度生產出區塊。為了解決這個問題，網路將難度提高到足以將礦工的速度降低到標準的每塊 10 分鐘的速度。

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.

由於礦工最近降低了算力，出塊時間比平常慢。比特幣區塊鏈現在將難度降低 4% 以上，以使驗證者的工作變得更容易。
