Bitcoin's hash rate is the single most important metric for understanding the security and health of the Bitcoin network. It measures the total computational power dedicated to mining Bitcoin and validating transactions, expressed in hashes per second. A higher hash rate means greater security, as it becomes exponentially more expensive for any attacker to compromise the network.
Onramp Terminal tracks hash rate data in real time, providing institutional-grade visibility into Bitcoin's security infrastructure.
Metric | Value
Current hash rate | ~820 EH/s
All-time high | ~850 EH/s (January 2026)
Mining difficulty | ~115T
Average block time | ~9.8 minutes
Active miners (estimated pools) | 15+ major pools
Network energy consumption | ~170 TWh/year (estimated)
Cost to 51% attack (1 hour) | >$15 billion (estimated)
Hash rate measures how many SHA-256 cryptographic hash calculations the Bitcoin network performs per second. Each hash is a miner's attempt to find the correct nonce that produces a block header hash below the network's difficulty target.
Unit | Hashes per Second | Context
KH/s (Kilohash) | 1,000 | Early CPU mining (2009)
MH/s (Megahash) | 1,000,000 | GPU mining era (2010-2012)
GH/s (Gigahash) | 1,000,000,000 | Early ASIC era (2013)
TH/s (Terahash) | 1,000,000,000,000 | Modern ASIC miners
PH/s (Petahash) | 10^15 | Mining pool scale
EH/s (Exahash) | 10^18 | Network-wide measurement
A single modern ASIC miner (like the Antminer S21 XP) produces approximately 270 TH/s. The entire network at 820 EH/s is equivalent to roughly 3 million such miners operating simultaneously.
Bitcoin's hash rate has grown exponentially since the network's inception:
Date | Hash Rate | Block Reward | Hardware Era
Jan 2009 | <1 MH/s | 50 BTC | CPU mining
Jan 2011 | ~120 GH/s | 50 BTC | GPU mining begins
Jan 2013 | ~25 TH/s | 25 BTC | First ASICs
Jan 2015 | ~300 PH/s | 25 BTC | Industrial mining
Jan 2017 | ~2.5 EH/s | 12.5 BTC | Mining farms scale
Jan 2019 | ~40 EH/s | 12.5 BTC | Post-2017 boom
Jan 2020 | ~110 EH/s | 12.5 BTC | Pre-halving
May 2021 | ~180 EH/s | 6.25 BTC | Pre-China ban peak
Jul 2021 | ~85 EH/s | 6.25 BTC | China mining ban crash
Jan 2022 | ~195 EH/s | 6.25 BTC | Full recovery
Jan 2023 | ~280 EH/s | 6.25 BTC | Bear market, hash rate grows
Jan 2024 | ~520 EH/s | 6.25 BTC | Pre-halving surge
Apr 2024 | ~600 EH/s | 3.125 BTC | Fourth halving
Jan 2025 | ~750 EH/s | 3.125 BTC | ETF era
Feb 2026 | ~820 EH/s | 3.125 BTC | Current
The China Mining Ban (May-July 2021) In May 2021, China banned Bitcoin mining, causing an unprecedented ~53% hash rate drop from 180 EH/s to ~85 EH/s. At the time, China accounted for approximately 65% of global hash rate. Within seven months, the hash rate had fully recovered as miners relocated to the United States, Kazakhstan, and other jurisdictions. This event proved Bitcoin's resilience: despite losing more than half its mining capacity overnight, the network never stopped producing blocks.
Post-Ban Geographic Redistribution Before the China ban, mining was heavily concentrated. After the ban, mining became significantly more geographically diverse:
Country | Pre-Ban Share (est.) | Current Share (est.)
United States | ~17% | ~38%
China | ~65% | ~15% (returned partially)
Russia | ~7% | ~12%
Canada | ~3% | ~6%
Kazakhstan | ~6% | ~5%
Other | ~2% | ~24%
Bitcoin's mining difficulty adjusts every 2,016 blocks (approximately every two weeks) to maintain an average block time of 10 minutes. When hash rate increases, difficulty increases proportionally, and vice versa.
Metric | Value
Current difficulty | ~115T
Next adjustment | ~3 days
Estimated next adjustment | +1.8%
Difficulty epoch | 424
The difficulty adjustment is one of Bitcoin's most elegant engineering features. It ensures that regardless of how much mining power joins or leaves the network, blocks continue to be produced approximately every 10 minutes.
Hash rate directly correlates with the cost of attacking the Bitcoin network. The primary theoretical attack vector is a 51% attack, where an attacker controls more than half the network's mining power to potentially double-spend transactions.
Current cost to execute a sustained 51% attack:
Attack Duration | Estimated Cost
1 hour | >$15 billion
24 hours | >$50 billion
1 week | >$250 billion
These estimates include: hardware acquisition (millions of ASIC miners), electricity costs, facility construction, and the opportunity cost of not mining honestly. In practice, a 51% attack on Bitcoin is economically irrational because:
For institutional allocators, rising hash rate is a fundamental indicator of network health. It represents real capital expenditure (billions of dollars in mining hardware and energy infrastructure) deployed by rational economic actors who expect Bitcoin to retain value over the useful life of their equipment (3-5 years).
Post-2024 halving, miners receive 3.125 BTC per block. At current prices, this represents approximately $315,000 per block, or roughly $45 million per day across all miners.
Metric | Value
Block reward | 3.125 BTC (~$315,000)
Average transaction fees per block | ~0.15-0.5 BTC
Total daily miner revenue | ~$45-48 million
Total annual miner revenue | ~$17 billion
Estimated all-in cost per BTC (efficient miner) | ~$45,000-55,000
Estimated all-in cost per BTC (average miner) | ~$65,000-80,000
The halving creates a natural selection pressure: only the most efficient miners survive. This drives continuous investment in newer, more energy-efficient hardware and access to cheaper energy sources.
Pool | Estimated Hash Rate Share | Headquarters
Foundry USA | ~32% | United States
AntPool | ~18% | International
F2Pool | ~12% | International
ViaBTC | ~11% | International
Binance Pool | ~7% | International
MARA Pool | ~5% | United States
Others | ~15% | Various
No single mining pool controls more than a third of hash rate, maintaining healthy decentralization.

Bitcoin's hash rate is approximately 820 EH/s (exahashes per second) as of February 2026. This means the network performs over 820 quintillion SHA-256 calculations per second. The all-time high of approximately 850 EH/s was reached in January 2026. Hash rate has grown roughly 10x since early 2021.
Hash rate measures the total computational power used to mine Bitcoin and process transactions. A higher hash rate means more miners are competing to validate blocks, which makes the network more secure against attacks. At 820 EH/s, Bitcoin is the most powerful computing network ever created. The cost to attack the network now exceeds $15 billion for even a one-hour assault.
Bitcoin's hash rate increases because mining remains profitable, driven by Bitcoin's price appreciation and improvements in ASIC efficiency. When price rises, mining becomes more profitable, attracting more miners. Additionally, each generation of mining hardware (ASICs) produces more hashes per watt, so the network gets more powerful even without proportional increases in energy consumption.
When China banned Bitcoin mining in May-July 2021, the hash rate dropped approximately 53% from 180 EH/s to about 85 EH/s, as China accounted for roughly 65% of global mining. The network never stopped operating. Within seven months, hash rate fully recovered as miners relocated to the U.S., Kazakhstan, Canada, and other countries, resulting in a more geographically decentralized network.
At the current hash rate of 820 EH/s, a 51% attack on Bitcoin would cost an estimated $15+ billion for just one hour, factoring in hardware acquisition, electricity, and infrastructure. A sustained 24-hour attack would cost over $50 billion. In practice, such an attack is economically irrational because it would crash Bitcoin's price, destroying the attacker's own investment.
