- Algorithm: SHA-256
- Block time: ~10 minutes
- Max supply: 21,000,000 BTC (fixed forever)
- Current block reward: 3.125 BTC (after April 2024 halving)
- Halving: Every 210,000 blocks (~4 years)
- Mining hardware: ASIC only
How Bitcoin works
Bitcoin enables peer-to-peer value transfer without banks or intermediaries. Transactions are verified by a global network of miners who compete to solve SHA-256 cryptographic puzzles. The winner adds the next block to the chain and earns the block reward.
Bitcoin's supply is hard-capped at 21 million coins, with new issuance halving every ~4 years. This controlled supply is the foundation of Bitcoin's value proposition as a scarce digital asset.
Bitcoin mining
Bitcoin mining requires dedicated ASIC hardware — general-purpose GPUs and CPUs became uncompetitive many years ago. Leading ASIC manufacturers include Bitmain (Antminer series) and Canaan (Avalon series).
