1. What Is Bitcoin Mining
Bitcoin mining is the process by which new bitcoins are created and transactions are confirmed. Miners use specialized hardware to solve proof-of-work puzzles, competing to append the next block and earn the block reward plus transaction fees.
2. How It Works
Miners assemble pending transactions into a candidate block and repeatedly hash its header, varying a nonce, until the hash meets a difficulty target. The first miner to find a valid hash broadcasts the block; other nodes verify and add it to the chain. The network adjusts difficulty every 2016 blocks to keep block time near 10 minutes. Mining pools combine hashrate from many miners and share rewards.
3. Why It Matters
Mining secures the Bitcoin network: rewriting history would require redoing the proof-of-work, which grows prohibitively expensive with confirmations. It also introduces the energy-use and centralization debates central to Bitcoin's politics, and it is the economic engine that pays for security.
4. Key Facts
- Uses ASIC hardware (Application-Specific Integrated Circuits)
- Difficulty adjusts every 2,016 blocks (~2 weeks)
- Mining pools dominate; solo mining is impractical at home
- Bitcoin's energy use is a major ongoing debate
