Bitcoin mining has reached a new peak! The 14-day moving average of the network hashrate has exceeded 1 zetahash per second (ZH/s) for the first time in its 16-year existence. This signals a significant rise in scale, especially with the upcoming difficulty adjustment at block height 915264, set to push mining difficulty past 140 trillion. This achievement follows four halving events and a remarkable period of growth, moving from gigahash speeds in 2010, to terahash in 2011, petahash in 2013, exahash in 2016, and now zetahash in 2025. This landmark underscores the continuous industrialization of Bitcoin mining, even as profit margins remain competitive.
Examining August’s production numbers, as reported by TheMinerMag, reveals contrasting trends between the largest mining firms and a group of smaller, second-tier operators. The leading companies, including MARA, IREN, CleanSpark, and Cango, showed relatively stable performance, with minor changes in realized hashrates compared to July.
MARA maintained its position at the top with 46.3 EH/s, producing 705 BTC, a modest 5% increase month-over-month. IREN and Cango each reported hashrates around 44 EH/s, generating 668 BTC and 664 BTC, respectively. CleanSpark mined 657 BTC at 43.2 EH/s, while Riot experienced a 7% increase to 40.5 EH/s, yielding 477 BTC. Riot’s growth was primarily driven by accounting practices rather than hardware expansion. TheMinerMag estimates their realized hashrate accounts for more than only direct mining activities, like cloud mining and power credits. Riot reported $16.1 million in power credits and demand response program benefits for August, affecting their reported hashrate.
In contrast, various smaller firms expanded more aggressively. Bitdeer increased their realized hashrate by almost 40% to 24.6 EH/s, mining 375 BTC. HIVE saw a nearly 28% increase to 16.2 EH/s, producing 247 BTC, while Cipher grew by over 18% to 15.8 EH/s with 236 BTC mined. Canaan, primarily known as a hardware manufacturer, also demonstrated double-digit growth, increasing by over 15% to 6.4 EH/s. This confirms what was observed in a previous Miner Weekly report: manufacturers are continuing to deploy assets and enter mining themselves when institutional demand slows, creating more competition for their own customers.
Not all miners experienced gains. Ionic saw a decrease of almost 6% to 6.8 EH/s, while Core Scientific declined by 3.7% to 10.8 EH/s. BitFuFu had the most significant reduction, decreasing their realized hashrate by 30% to 3.6 EH/s, although they still mined 55 BTC.
The August performance overview illustrates a dynamic competitive landscape. The largest miners still possess the most substantial operations, but their growth has slowed as the network reaches record scales. Meanwhile, smaller miners and hardware producers are quickly deploying capacity, either through strategic implementations or by activating uncommitted machines. As Bitcoin enters the zetahash era with heightened mining difficulty, the ability of these second-tier operators to expand in challenging economic times indicates a new stage in the industry’s evolution. This implies a more decentralized mining future.
