Understanding Bitcoin Network Hashrate
This chart illustrates historical changes in the total network hashrate of Bitcoin (BTC) over various time periods.
It provides an estimate of how many hashes per second BTC miners collectively perform.
An increase in BTC's total network hashrate may indicate growing miner interest due to:
- Higher mining profitability
- Additional energy deployment by large market players
A decrease in network hashrate could result from:
- Reduced profitability
- Network failures
- Issues affecting major mining pools
What Is Hashrate?
Hashrate measures the computational power of mining equipment (ASICs, GPUs, CPUs). It quantifies solutions (hashes) processed per second.
In Bitcoin, a solution is called a hash (H), and mining performance is measured in H/s (hashes per second).
Hashrate Measurement Units:
| Unit | Equivalent | Hashes Per Second |
|--------|----------------------------|----------------------------|
| 1 KH/s | 1,000 H/s | 1,000 |
| 1 MH/s | 1,000 KH/s | 1,000,000 |
| 1 GH/s | 1,000 MH/s | 1,000,000,000 |
| 1 TH/s | 1,000 GH/s | 1,000,000,000,000 |
| 1 EH/s | 1,000 PH/s | 1,000,000,000,000,000,000 |
Current Bitcoin Network Hashrate:
788.67 EH/s = 788,665,185,752,318,900,000 H/s
GPU Hashrate Explained
A single mining rig or GPU processes millions of hashes per second.
For example:
- An Nvidia RTX 3060 delivers ~48 MH/s on the Ethash algorithm (used for ETH, ETC, etc.).
- This means it calculates 48,000,000 solutions per second.
Key Notes on GPU Mining:
- Hashrates vary by algorithm—comparisons are only valid within the same algorithm.
- Some algorithms measure solutions as "sol" (solutions), indicating more complex computations than simple hashes.

What Is Network Hashrate?
Bitcoin’s network hashrate reflects the combined computational power of all miners securing the blockchain.
It’s a calculated metric derived from:
- Current network difficulty
- Average block time
- Real-time data from recent blocks
Current Bitcoin Network Hashrate:
788.67 EH/s
Why Network Hashrate Matters
Changes in a cryptocurrency’s total hashrate signal shifts in mining profitability.
How Mining Rewards Are Distributed:
- Fixed Block Reward: The blockchain allocates a set reward (e.g., 1 BTC per block).
Proportional Share: Miners earn rewards proportional to their contributed hashrate.
- Example: If you provide 1 GH/s in a 10 GH/s network, you earn 10% of rewards.
- Competition Dynamics: More miners = smaller individual shares. Higher hashrate = larger rewards.

FAQ: Bitcoin Hashrate
1. How often does Bitcoin’s network hashrate change?
The hashrate updates continuously as miners join/leave the network. Major shifts often follow price volatility or hardware advancements.
2. Does higher hashrate mean better security?
Yes. A higher hashrate makes the network more resistant to 51% attacks.
3. Can I mine Bitcoin with a GPU?
While possible, ASICs dominate BTC mining due to their superior efficiency. GPUs are better suited for other coins.
4. What causes sudden drops in hashrate?
Common reasons include:
- Power outages in mining hubs
- Regulatory crackdowns
- Profitability drops due to price declines
5. How is hashrate calculated?
It’s inferred from block difficulty and the average time between blocks.
6. Where can I check real-time hashrate data?
Use blockchain explorers like Blockchain.com or dedicated mining platforms.
