Definition
Mining Pool is a group of miners who combine their computational power to search for blocks together. When the pool finds a block, the reward is distributed among participants proportionally to their contribution.
Why Pools Exist
At current Bitcoin hashrate, the chance of finding a block alone is extremely small:
- Solo miner might search for years
- In a pool, you get stable income
- Everyone's contribution is fairly accounted
How It Works
- Miners connect to the pool server
- Pool distributes work among participants
- Each solves their part of the puzzle
- When someone finds a block — reward is split
- Pool takes a fee (usually 1-3%)
Largest Bitcoin Pools (2024)
| Pool | Hashrate Share |
|---|---|
| Foundry USA | ~30% |
| AntPool | ~20% |
| F2Pool | ~12% |
| ViaBTC | ~10% |
| Binance Pool | ~8% |
Reward Models
- PPS (Pay Per Share) — payment for each share of work
- PPLNS — payment for last N shares
- FPPS — PPS + transaction fees
Centralization Risks
If one pool controls >50% of hashrate — a "51% attack" is theoretically possible. That's why distribution among pools is important.
Tip
For regular investors, mining through pools is often less profitable than a simple DCA strategy — buying cryptocurrency with the same money spent on equipment and electricity.
