比特币难度刚刚创下历史新高

链上数据显示，在最新的网络调整中，比特币难度已连续第三次上升。这对 BTC 意味着什么。

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.

比特币（BTC）难度刚刚创下历史新高。据CoinWarz数据显示，本次网络调整期间，BTC难度出现积极变化。这里的“难度”是一个衡量比特币矿工在网络上挖矿的难度的指标。

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

该指标的值每隔几周刷新一次，无需人工参与；中本聪编写的代码会自动进行调整。

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.

最近一次此类调整发生在过去一天，导致环比上涨困难。下面的图表显示了该指标的值在过去几个月中的变化情况。

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.

该图显示，比特币难度在前两次调整中也出现了跳跃，但最近一次超过 6% 的涨幅是三者中最大的。

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.

至于为什么最近该链的难度不断上升，原因在于算力一直在观察的趋势。 “算力”是衡量矿工作为一个整体连接到比特币区块链的计算能力总量的指标。

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:

下面是来自 Blockchain.com 的图表，显示了该 BTC 指标在过去一年中的 7 天平均值的趋势：

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.

该图显示，比特币 7 天平均算力已经攀升了一段时间，并创下历史新高 (ATH)。过去几周的上升趋势尤其剧烈，这表明矿商的扩张变得更加积极。

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.

现在，这与困难有什么相关性？该网络的核心特征之一是其出块时间始终保持在 10 分钟左右。

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.

每当矿工增加功率时，他们的采矿任务就会变得更快，并以比这个标准更快的速度生产区块。为了抵消这种速度的增加，网络使矿工更难执行任务，使每个区块的时间回到 10 分钟。

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.

加密货币的算力最近出现爆炸式增长，因此链只能按照设计做出反应，适当提高难度至新纪录。

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.

但为什么 BTC 的创造者要添加这个限制呢？区块补贴是生产更多比特币的唯一手段，可以通过限制矿工通过区块并获得这些奖励的速度来限制。

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

该资产的供应量不断增长，但至少困难的存在意味着其通胀只会以可预测的速度发生。
