比特幣難度剛創下歷史新高

鏈上數據顯示，在最新的網路調整中，比特幣難度已連續第三次上升。這對 BTC 意味著什麼。

Bitcoin (BTC) difficulty has just set a new all-time high. According to data from CoinWarz, the BTC difficulty has seen a positive change during the latest network adjustment. The “Difficulty” here is a metric that tracks how hard the Bitcoin miners would find it to mine on the network.

比特幣（BTC）難度剛創下歷史新高。根據CoinWarz數據顯示，本次網路調整期間，BTC難度有正向變化。這裡的「難度」是一個衡量比特幣礦工在網路上挖礦的難度的指標。

This indicator's value refreshes every couple of weeks without human involvement; the code Satoshi wrote automatically makes the adjustments.

此指標的數值每隔幾週刷新一次，無需人工參與；中本聰編寫的程式碼會自動進行調整。

The latest such adjustment occurred during the past day and resulted in the difficulty of going up the chain. Below is a chart that shows how this metric’s value has changed over the last few months.

最近一次此類調整發生在過去一天，導致環比上漲困難。下面的圖表顯示了該指標的值在過去幾個月中的變化。

The graph shows that the Bitcoin difficulty also saw jumps during the previous two adjustments, but this latest increase of more than 6% is the largest out of the three.

該圖顯示，比特幣難度在前兩次調整中也出現了跳躍，但最近一次超過 6% 的漲幅是三者中最大的。

As for why the chain has been upping its difficulty recently, the reason lies in the trend that the hashrate has been observing. The “Hashrate” is a measure of the total amount of computing power that the miners as a whole have connected to the Bitcoin blockchain.

至於為什麼最近該鏈的難度不斷上升，原因在於算力一直在觀察的趨勢。 「算力」是衡量礦場工作為一個整體連接到比特幣區塊鏈的運算能力總量的指標。

Here is a chart from Blockchain.com that shows the trend in the 7-day average value of this BTC indicator over the past year:

下面是來自 Blockchain.com 的圖表，顯示了該 BTC 指標在過去一年中的 7 天平均值的趨勢：

The graph shows that the 7-day average Bitcoin hashrate has been climbing for a while now and hitting new all-time highs (ATHs). The uptrend has been particularly sharp during the last couple of weeks, which suggests the miners have become more aggressive with their expansion.

該圖顯示，比特幣 7 天平均算力已經攀升了一段時間，並創下歷史新高 (ATH)。過去幾週的上升趨勢尤其劇烈，這表明礦商的擴張變得更加積極。

Now, what's the relevance of this to the difficulty? Well, one of the network's core features is that its block time remains consistent around the 10-minute mark.

現在，這與困難有什麼相關性？這個網路的核心特徵之一是其出塊時間始終保持在 10 分鐘左右。

Whenever miners add power, they become faster at their task of mining and churn out blocks at a faster pace than this standard. To counteract this speed increase, the network makes it harder for miners to perform their tasks, bringing them back to 10 minutes per block.

每當礦工增加功率時，他們的採礦任務就會變得更快，並以比這個標準更快的速度生產區塊。為了抵​​消這種速度的增加，網路使礦工更難執行任務，使每個區塊的時間回到 10 分鐘。

The hashrate of the cryptocurrency has seen an explosion recently, so the chain has only responded as designed by appropriately increasing the difficulty to a new record.

加密貨幣的算力最近出現爆炸性增長，因此鏈只能按照設計做出反應，適當提高難度至新紀錄。

But why did BTC's creator add this limitation at all? The block subsidy, serving as the only means of producing more BTC, can be constrained by restricting how fast miners can go through blocks and earn these rewards.

但為什麼 BTC 的創造者要增加這個限制呢？區塊補貼是生產更多比特幣的唯一手段，可以透過限制礦工通過區塊並獲得這些獎勵的速度來限制。

The asset's supply is continuously growing, but at least the difficulty's existence means its inflation is only happening at a predictable pace.

該資產的供應量不斷增長，但至少困難的存在意味著其通膨只會以可預測的速度發生。

Bitcoin declined under $67,000 yesterday, but the asset quickly bounced back as its price recovered to $69,700.

昨天，比特幣跌破 67,000 美元，但該資產迅速反彈，價格回升至 69,700 美元。
