PremiumCryptocurrency Mining
A Bitcoin mining farm
Cryptocurrency mining is the process of validating transactions and adding them to a blockchain. Miners use powerful computers to solve complex mathematical problems and are rewarded with crypto.
⛏️ Hashrate: Bitcoin's total hashrate exceeds 600 EH/s (exahashes per second) as of 2024.
How Mining Works
- Transactions are broadcast to the network
- Miners collect transactions into a "block"
- Miners compete to solve a complex mathematical puzzle (Proof-of-Work)
- First miner to solve receives the block reward
- The block is added to the blockchain
Mining Hardware Evolution
| Era | Hardware | Hashrate | Energy Use |
|---|---|---|---|
| 2009 | CPU Mining | ~5 MH/s | Low |
| 2010 | GPU Mining | ~50 MH/s | Medium |
| 2013 | ASIC (10nm) | ~5 GH/s | High |
| 2018 | ASIC (7nm) | ~50 TH/s | Very High |
| 2024 | ASIC (3nm) | ~250 TH/s | Extreme |
Top Mining Countries (2024)
- United States: 40% of global hashrate
- China: 15% (banned in 2021, now underground)
- Kazakhstan: 13%
- Russia: 12%
- Canada: 6%
Environmental Impact
Bitcoin mining consumes ~120 TWh annually, comparable to Norway. However, mining is increasingly powered by renewable energy:
- ~50% of mining uses renewable energy (2024)
- Mining also captures wasted energy (flared gas, excess hydro)
- Ethereum's transition to PoS reduced energy use by 99.95%
