比特幣（BTC）算力創下歷史新高，展示了網路安全性的不斷增強

比特幣網路哈希率（保護比特幣網路的總運算能力）於 10 月 21 日達到每秒 769.8 exahashes (EH/s) 的歷史新高。

The Bitcoin ( BTC ) hashrate has hit a new record high, highlighting the growing security of the world’s first blockchain network.

比特幣（BTC）算力創下新高，凸顯了世界上第一個區塊鏈網路日益增長的安全性。

The Bitcoin network hashrate — the total computing power securing the Bitcoin network — reached an all-time high of 769.8 exahashes per second (EH/s) on Oct. 21.

比特幣網路哈希率（保護比特幣網路的總運算能力）於 10 月 21 日達到每秒 769.8 exahashes (EH/s) 的歷史新高。

The hashrate has been in a steady uptrend since 2021, BitInfoCharts data shows. The hashrate's escalation is largely attributed to advances in mining hardware, such as application-specific integrated circuits (ASICs).

BitInfoCharts 數據顯示，自 2021 年以來，算力一直處於穩定上升趨勢。算力的提升很大程度上歸因於採礦硬體的進步，例如專用積體電路（ASIC）。

While the Bitcoin hashrate indicates the increasing security of the network, it also drives up the cost to mine Bitcoin.

雖然比特幣算力顯示網路安全性不斷提高，但它也推高了比特幣的開採成本。

Together with the reduction in block rewards from the upcoming 2024 Bitcoin halving, the rising hashrate might lead to miner consolidation, especially among smaller companies.

再加上即將到來的 2024 年比特幣減半導致的區塊獎勵減少，算力的上升可能會導致礦商整合，尤其是在小公司中。

Bitcoin miner consolidation expected among smaller firms

比特幣礦商預計將在小公司中整合

As the cost of mining a Bitcoin increases, smaller firms with less efficient mining rigs might become unprofitable, leading them to shut down their operations or search for mining headquarters with lower energy costs.

隨著開採比特幣的成本增加，採礦設備效率較低的小公司可能會變得無利可圖，導致他們關閉業務或尋找能源成本較低的採礦總部。

Energy-efficient mining equipment is crucial for miners to remain profitable after the fourth Bitcoin halving, according to Nazar Khan, co-founder and chief operating officer of TeraWulf.

TeraWulf 聯合創始人兼首席營運長 Nazar Khan 表示，節能挖礦設備對於礦工在第四次比特幣減半後保持盈利至關重要。

In an interview with Cointelegraph, Khan mentioned:

Khan 在接受 Cointelegraph 採訪時提到：

“The rising hashrate will continue to drive up the difficulty and cost to mine Bitcoin, especially ahead of the halving, which will reduce miner rewards.”

“不斷上升的算力將繼續推高比特幣開採的難度和成本，尤其是在減半之前，這將減少礦工的獎勵。”

TeraWulf is the world’s sixth-largest Bitcoin mining company, valued at over $670 million, according to Companiesmarketcap. Despite the halving of block rewards, it plans to further expand its mining operations this year.

根據 Companiesmarketcap 的數據，TeraWulf 是全球第六大比特幣挖礦公司，估值超過 6.7 億美元。儘管區塊獎勵減半，但它仍計劃今年進一步擴大採礦業務。

Despite the rising Bitcoin mining difficulty, mining firms have not increased their Bitcoin selling.

儘管比特幣挖礦難度不斷上升，礦業公司並沒有增加比特幣銷售。

On Oct. 20, Bitcoin mining firms sent a total of 2,916 BTC to centralized cryptocurrency exchanges (CEXs), marking the fourth-lowest day of selling in 30 days, according to CryptoQuant data.

根據 CryptoQuant 的數據，10 月 20 日，比特幣挖礦公司總共向中心化加密貨幣交易所（CEX）發送了 2,916 枚 BTC，這是 30 天內銷量第四低的一天。

Some miner consolidation was observed after the Bitcoin halving on May 10, as the network's hashrate dropped to a two-month low of 575 (EH/s).

5 月 10 日比特幣減半後，隨著網路算力跌至兩個月低點 575（EH/s），出現了一些礦商整合。

James Butterfill, head of research at CoinShares, attributed May’s drop in hashrate to miners “beginning to turn off unprofitable rigs.”

CoinShares 研究主管 James Butterfill 將 5 月算力下降歸因於礦工「開始關閉無利可圖的礦機」。
