Where Are Bitcoin's Miners Moving? The 2026 Hashrate Geography Map

Five years after China expelled its miners, the global hashrate map looks nothing like it did in 2021. The network crossed 1 zettahash per second for the first time in September 2025, peaked near 1,157 EH/s that October, and has since settled around 900 to 1,000 EH/s as post-halving economics squeeze out less efficient operators. Where that compute power physically sits determines how resilient Bitcoin is against state-level coercion: a question that matters to every user, every layer-2 protocol, and every application built on top of the base chain.

This article maps the 2026 hashrate distribution country by country, traces the migration corridors that opened after China's ban, and examines what geographic concentration means for censorship resistance.

The Current Hashrate Map: Who Mines Where

Hashrate measurement relies on imperfect proxies: IP geolocation from mining pool connections, self-reported facility data, and energy consumption modeling. The Cambridge Centre for Alternative Finance (CCAF) maintains the most widely cited dataset, supplemented by industry trackers like Hashrate Index. The numbers below synthesize multiple sources and represent approximate ranges rather than exact figures.

Measurement caveat: VPN usage, pool-hop obfuscation, and underground operations (particularly in China) make precise country-level attribution difficult. Published estimates can diverge by 5 to 10 percentage points depending on methodology.

The United States: Dominance and Its Discontents

The United States has consolidated its position as the world's largest mining jurisdiction. Publicly listed US miners alone accounted for approximately 31.5% of global network hashrate by mid-2025 according to JPMorgan analysis, and total US share (including private operations) reached roughly 42.5% by June 2026. The country benefits from deep capital markets, a well-understood regulatory environment for energy procurement, and post-halving consolidation that favors institutional-scale operators.

Texas remains the epicenter, offering deregulated electricity markets where miners participate in demand-response programs with ERCOT, the state grid operator. Georgia, New York, North Dakota, and Pennsylvania host significant operations as well, each leveraging different energy profiles: nuclear in Pennsylvania, natural gas in Appalachia, wind in the Great Plains.

The Centralization Tradeoff

A single country controlling over 40% of hashrate raises structural questions for a network designed to be permissionless. US mining operations are subject to OFAC sanctions compliance, SEC reporting requirements for public companies, and state-level energy regulations. In a scenario where the US government mandated transaction filtering at the miner level, 42% of the network's block production capacity would be directly affected.

This is not hypothetical. In January 2025, research revealed that F2Pool had excluded 15 transactions from OFAC-listed addresses, demonstrating that voluntary censorship-resistance commitments can fail under regulatory pressure. Foundry USA, the world's largest pool, routinely handles 30 to 37% of global hashrate: a US-domiciled entity producing roughly a third of all Bitcoin blocks.

Russia: Mining Under Expanding Restrictions

Russia holds the number-two position globally with approximately 16 to 17% of hashrate, concentrated in Siberia's hydroelectric belt around Irkutsk. BitRiver, the country's largest industrial mining operator, built its model on energy-cost arbitrage using cheap Siberian power. However, that model is under pressure from multiple directions.

Russia legalized registered crypto mining in 2024, then almost immediately began restricting it. Year-round bans took effect on January 1, 2026 in Buryatia and Zabaikalsky Krai. In August 2026, Moscow, the Moscow Region, and parts of Kursk were banned from mining through 2032. In total, 13 Russian regions now prohibit mining, targeting an estimated 50,000 miners.

BitRiver also carries US Treasury sanctions imposed in 2022 on the grounds that Russian mining companies help the country monetize energy resources in ways that could offset Western sanctions. The combination of domestic grid-protection restrictions and international sanctions creates a hostile operating environment. Russia's share has declined for two consecutive quarters and is likely to continue eroding.

China: The Ban That Did Not Stick

China's State Council banned crypto mining in May 2021, triggering the largest hashrate migration in Bitcoin's history. Within months, China's share dropped from over 65% to near zero in official statistics. The reality turned out to be more complicated.

By late 2025, underground Chinese operations had reclaimed roughly 14% of global hashrate, making China the third-largest mining hub again. CryptoQuant estimates put the real figure between 15% and 20%. Seasonal hydropower in Sichuan, proximity to ASIC manufacturing, and deep operational expertise sustain activity despite the ban. Hardware sales data provides corroborating evidence: Canaan Inc., the world's second-largest mining machine manufacturer, reported that China accounted for over 50% of its sales in Q2 2025, up from 2.8% in 2022.

Jurisdictional risk in practice: China's mining rebound illustrates a core dynamic: hashrate follows cheap energy regardless of legal status. Bans push operations underground rather than eliminating them, creating a shadow mining economy with no regulatory oversight, no safety standards, and no public accountability.

New Mining Corridors: Middle East, Africa, and Latin America

The most interesting developments in the 2026 hashrate map are not in the top three countries. They are in the emerging corridors where governments actively court miners as tools for energy monetization.

The Gulf: Stranded Gas and Sovereign Capital

The MENA region accounts for 38% of the world's flared gas: energy that is literally burned and wasted at oil and gas extraction sites. For mining operators, flared gas represents a near-zero-cost energy source that also reduces methane emissions.

The UAE leads the Middle East with roughly 4% of global hashrate, the highest in the region. The Oman Investment Authority acquired a stake in Crusoe Energy Systems, a US company that converts stranded natural gas into compute power. Oman has invested over $1.1 billion in green mining infrastructure, operating facilities in the Special Economic Zone at Duqm with combined hashrate representing 0.5 to 1% of the global network. The government frames mining as an energy monetization strategy paired with technology sector development.

State-backed mining with KYC/AML compliance, sovereign wealth fund investment, and explicit government support make the Gulf corridor distinctive. These are not rogue operations: they are industrial policy.

Ethiopia: Hydropower's Promise and Limits

Ethiopia attracted significant mining investment on the strength of cheap hydroelectric power from the Grand Ethiopian Renaissance Dam (GERD). Phoenix Group deployed 52 MW of capacity powered by GERD, claiming 90% of its mining energy came from renewable hydro. In 2025, BitX signed an MOU with Ethiopia Mining Farm to expand operations further.

Then the drought hit. In September 2026, Ethiopian Electric Power rationed miners to 23% of contracted power after dam inflows dropped roughly 20%. Bitcoin mining had at one point consumed as much as a third of Ethiopia's total power output: a dependency that became untenable when water levels fell. The government had already stopped issuing new mining licenses in February 2024 and announced in August 2025 that active operations would be gradually phased out.

Ethiopia's experience illustrates both the opportunity and fragility of hydro-dependent mining. Cheap power attracts hashrate, but that power can be curtailed overnight when competing demands (agriculture, cities, industry) take priority. Mining is the load that gets shed first.

Paraguay: The Surplus That Is Running Out

Paraguay commands roughly 4.3% of global hashrate (~43 EH/s as of Q2 2026), powered by structural hydroelectric surplus from the Itaipu and Yacyreta dams. Electricity costs around $0.03/kWh made it one of the cheapest legal mining jurisdictions in the world. HIVE Digital Technologies acquired Bitfarms' Paraguay operations in January 2025 and built out its Yguazu campus to 300 MW of renewable capacity.

The clock is ticking, however. ANDE, Paraguay's state power utility, has declared that every current crypto mining contract expires on December 31, 2027: a deadline it says is non-negotiable. Domestic consumption growth and traditional industrial demand are projected to absorb the surplus that miners currently use. AI data centers are also competing for the same power allocation.

The Shift Since China's Ban: Before and After

The transformation of the hashrate map over five years is dramatic. Before China's ban, geographic concentration was far worse than it is today.

The top-three concentration has improved modestly: China alone held 65% in 2021, while the US, Russia, and China collectively hold roughly 68 to 74% today. The improvement is that the remaining 26 to 32% is now spread across a wider set of jurisdictions rather than being dominated by a single country. Kazakhstan's rise and fall is instructive: it absorbed 18% of global hashrate immediately post-ban, then shed most of it due to energy caps, regulatory crackdowns, and grid instability.

Pool Concentration: The Other Centralization Vector

Geographic distribution tells only half the story. Even if hashrate were perfectly distributed across dozens of countries, the mining pools that coordinate block production represent a separate centralization vector.

As of mid-2026, the top four pools produce roughly 73% of all Bitcoin blocks, and the top six pools mine over 95%. Foundry USA alone handles 30 to 37% of total network hashrate. These pools, not individual miners, select which transactions go into blocks. A pool operator can implement transaction filtering without the knowledge or consent of the miners pointing hashrate at it: exactly the kind of opaque censorship that undermines the neutrality guarantees Bitcoin users depend on.

Stratum V2: Returning Transaction Selection to Miners

The Stratum V2 protocol addresses pool-level centralization through a feature called Job Declaration, which lets individual miners construct their own block templates rather than accepting the pool's template. In June 2026, DMND mined Bitcoin block 955,318: the first documented instance of a miner independently building its own block template in a production pool environment.

In May 2026, seven major pools representing approximately 75% of global hashrate joined the Stratum V2 Working Group: Foundry USA, AntPool, F2Pool, SpiderPool, MARA Pool, Block Inc., and DMND. However, only Braiins Pool and DMND currently run Stratum V2 with Job Declaration in production, representing roughly 3 to 5% of hashrate. The SRI working group projects that V2 could become the default protocol for new ASIC firmware shipments by end of 2026, potentially reaching 40 to 60% of network hashrate: but Job Declaration adoption will lag protocol adoption significantly.

Political Implications of Hashrate Concentration

Where hashrate sits determines which governments can exert pressure on block production. The current distribution creates several distinct risk scenarios.

US Regulatory Overreach

With over 40% of hashrate under US jurisdiction, a federal mandate requiring miners to filter specific transactions (sanctioned addresses, for example) would affect block production probability for targeted transactions. Transactions would still confirm eventually through non-compliant miners in other jurisdictions, but confirmation times could increase from minutes to hours depending on the hashrate split between compliant and non-compliant miners.

Multi-Jurisdictional Coordination

The US and Russia together control approximately 55 to 59% of hashrate. While coordinated action between these two governments is unlikely given current geopolitics, the theoretical 51% threshold sits within reach of just two jurisdictions. Adding China's underground hashrate pushes the combined figure above 70%. These are the kinds of concentration numbers that the decentralization community has historically flagged as concerning.

Hashrate as Geopolitical Leverage

Governments are beginning to treat hashrate as a strategic asset. The Gulf states frame mining as sovereign energy policy. Russia legalized mining partly to monetize sanctioned energy exports. The US Strategic Bitcoin Reserve debate has raised questions about whether government Bitcoin holdings create incentives to protect or control domestic mining capacity. When hashrate becomes a matter of national interest, the line between supporting and controlling it gets thinner.

Why Hashrate Geography Matters for Layer 2

Every Bitcoin layer-2 protocol depends on the base layer's security guarantees. Whether it's Spark, Lightning, or a rollup, the ability to settle transactions on L1 without censorship is the fundamental assumption that makes off-chain scaling viable.

For Spark specifically, users hold pre-signed exit transactions that allow them to unilaterally withdraw funds to Bitcoin L1 if operators become unavailable. This exit path only works if miners will include those transactions in blocks. If a significant fraction of hashrate filters certain transaction types, exit guarantees weaken: the time to confirm an exit transaction increases, and the security model degrades from"you can always leave" to "you can eventually leave."

Geographic diversification of hashrate is therefore not just a Bitcoin L1 concern. It is infrastructure for the entire stack of protocols, wallets, and applications built on top. The energy mix powering miners and their physical distribution across jurisdictions directly affect the credibility of self-custody and censorship-resistance claims made by any Bitcoin-based system.

What Healthy Distribution Would Look Like

There is no consensus on an ideal hashrate distribution, but several properties are broadly desirable:

• No single country controls more than 25 to 30% of global hashrate
• No two geopolitically aligned countries together exceed 50%
• At least 5 to 10 countries each contribute 5% or more
• Pool-level transaction selection is returned to individual miners via protocols like Stratum V2
• Underground mining is minimized through reasonable regulatory frameworks rather than blanket bans

The current distribution fails the first two criteria. The US alone exceeds 30%, and the US plus Russia together exceed 50%. However, the trend line is encouraging in some dimensions: the number of countries hosting meaningful hashrate has increased from roughly 5 in 2021 to over 15 in 2026. The Gulf states, East Africa, and Latin America are building mining capacity that did not exist five years ago.

Looking Ahead: Forces Shaping the 2027 Map

Several forces will reshape the hashrate map over the next 12 to 18 months:

• Paraguay's mining contract expiry in December 2027 could redistribute 4 to 5% of global hashrate
• Russia's expanding regional bans will continue pushing its share downward, potentially below 15%
• Ethiopia's drought-driven power cuts may become permanent policy shifts if climate patterns persist
• Stratum V2 adoption will partially decouple geographic concentration from censorship risk by distributing transaction selection authority
• AI data center competition for cheap power will increase pressure on miners in every jurisdiction, particularly in markets like Paraguay and Canada where compute demand is growing
• Next-generation ASICs with improved efficiency (sub-15 J/TH) will allow profitable mining in higher-cost jurisdictions, potentially dispersing hashrate more broadly

The bottom line: Bitcoin's hashrate geography has improved from the extreme concentration of the China-dominant era, but the current US-heavy distribution introduces its own risks. Diversification is an ongoing process, not a solved problem. The technical countermeasure that matters most in the near term is Stratum V2's Job Declaration: it addresses censorship risk at the protocol level rather than depending on the political goodwill of any particular government.
