Bitcoin’s network hashrate has surged to a new all-time high of 194.95 exahash per second (EH/s) on December 8, 2021, a remarkable milestone that underscores the resilience of the world’s largest cryptocurrency network. The record comes just months after China’s sweeping crackdown on cryptocurrency mining forced a massive exodus of mining operations — and at a time when bitcoin’s price has pulled back more than 25% from its November peak.
TL;DR
- Bitcoin hashrate hit 194.95 EH/s on December 8, surpassing the previous ATH of 191.42 EH/s set on May 9
- The network has recovered dramatically from China’s mining ban, which triggered the largest difficulty drop in Bitcoin’s history (27.94%)
- Mining difficulty has increased nine consecutive times since the post-ban low
- Top pools include Antpool (19.39%), F2pool (14.16%), and Foundry USA (13.07%)
- Mining remains profitable, with a 110 TH/s machine earning approximately $22/day at current prices
A Record Built on Resilience
The numbers tell a striking story of recovery. After China’s regulatory assault on crypto mining in mid-2021, Bitcoin’s hashrate plummeted. The network experienced its largest-ever mining difficulty drop of 27.94%, followed by another 4.81% decline. At its lowest point, observers questioned whether the network could recover before the year was out.
Recover it did — and then some. Since those summer lows, Bitcoin’s mining difficulty has increased nine consecutive times. The difficulty adjustment on December 11 pushed the parameter to 24.1 trillion, just shy of the all-time high of 25 trillion set in May. The hashrate has surged 163% in just five months, reflecting the rapid deployment of mining infrastructure in new jurisdictions across North America, Central Asia, and elsewhere.
The New Mining Landscape
The distribution of mining power has shifted significantly since the last hashrate record in May. Antpool now leads with 19.39% of the global hashrate, equivalent to approximately 34.6 EH/s. F2pool holds the second position at 14.16% (25.27 EH/s), while Foundry USA has emerged as a major player, capturing 13.07% of the global hash power (23.32 EH/s). Foundry’s rise reflects the broader trend of institutional mining operations establishing themselves in the United States.
Perhaps the most intriguing development is the substantial presence of “unknown” or stealth miners, which collectively represent 12.20% of global hashrate — roughly 21.77 EH/s. This makes unknown hashrate the fifth-largest mining entity on the network. The concentration of unidentified hash power has been a prominent feature throughout the fourth quarter of 2021, raising questions about who is operating these machines and from where.
Next-Gen Hardware Driving Growth
Industry observers attribute much of the hashrate growth to the delivery of next-generation mining equipment ordered during the bull market. Throughout 2020 and the first half of 2021, enterprise mining operations placed massive orders for top-of-the-line ASIC machines from manufacturers like Bitmain and MicroBT. Many of these orders were scheduled for delivery by year-end 2021 or early 2022, and the December hashrate record suggests that thousands of new machines are now coming online.
Despite the ongoing deployment, mining economics remain favorable. A machine producing 110 terahash per second (TH/s), paying $0.12 per kilowatt-hour (kWh) in electricity, can generate approximately $22 per day at current bitcoin prices around $50,000. This profitability continues to incentivize the expansion of mining operations worldwide.
Regulatory Context and Global Redistribution
The hashrate record is perhaps most remarkable for what it represents geopolitically. China’s crackdown, which included bans on mining operations in key provinces like Sichuan and Inner Mongolia, was expected to cripple Bitcoin’s network security. Instead, it triggered a wholesale redistribution of mining power to jurisdictions with more favorable — or at least less hostile — regulatory environments. The United States, Kazakhstan, and other nations have absorbed significant portions of the displaced Chinese hashrate.
This geographic diversification may ultimately strengthen Bitcoin’s resilience. A more distributed mining network is less vulnerable to regulatory action from any single government, addressing one of the key systemic risks that critics have long identified.
Why This Matters
Bitcoin’s hashrate is the foundational security metric of the network. It represents the total computational power dedicated to processing transactions and securing the blockchain. A higher hashrate means greater resistance to attacks and greater confidence in the network’s integrity. The fact that Bitcoin has not only recovered from China’s crackdown but has pushed to new highs — even as its price has corrected significantly — sends a powerful signal about the network’s structural strength and the long-term commitment of the mining industry. For regulators and institutional investors watching from the sidelines, the hashrate record is evidence that Bitcoin’s infrastructure can withstand even the most aggressive government interventions.

163% recovery in five months after a 27.94% difficulty drop. this network does not care about your country bans
chinese miners just packed up and moved to kazakhstan and texas. the hashrate went nowhere, it just changed zip codes
22 bucks a day on a 110 TH machine at those prices. wonder how many of those rigs are now sitting in warehouses after the bear market hit
