Mining is the process by which transactions on a Proof of Work blockchain are validated and new blocks are added to the chain. Miners use specialized hardware to solve complex cryptographic puzzles, and the first to find the solution earns the right to add the next block and receive a reward.
How Mining Works
Miners compete to find a hash value that meets the network's difficulty target. This requires enormous computational power and energy. Once a valid hash is found, the miner broadcasts the block to the network for verification by other nodes.
Mining Rewards
Miners receive newly minted coins (block rewards) plus transaction fees from all transactions included in the block. Bitcoin's block reward started at 50 BTC and halves approximately every four years.
Mining Equipment
ASIC Miners: Application-Specific Integrated Circuits designed specifically for mining. Most efficient for Bitcoin.
GPU Mining: Using graphics cards — common for altcoin mining.
Mining Pools: Groups of miners who combine their computational power and share rewards proportionally.
