What is Mining?
Mining is the process of validating transactions and securing a Proof of Work blockchain by solving computational puzzles. The first miner to solve the puzzle earns newly minted coins plus transaction fees.
How does Mining work?
- Miners gather pending transactions from the mempool.
- Hardware performs billions of hash operations to find a valid solution.
- The winning miner broadcasts the block for network verification.
- The block is added to the chain and the miner receives the reward.
- Difficulty adjusts every
2016blocks to maintain consistent block times.
Why does Mining matter?
It provides economic security making Bitcoin resistant to double-spending. The high cost of attacking the network requiring majority hashrate is what makes PoW blockchains trustworthy.
Key features of Mining
- Computational competition to add blocks
- Block rewards issue new cryptocurrency
- Difficulty adjusts automatically
- Requires specialized ASIC hardware
Examples of Mining
Bitcoin miners solve SHA-256 puzzles to earn BTC. Large farms run 1000+ machines in regions with cheap electricity.
Individual miners join pools to earn smaller, more frequent payouts.
