Mining
Protocol
Producing blocks via proof of work to secure a network.
Mining uses computational work to propose and validate blocks in proof of work systems. Miners compete to solve puzzles, earn rewards, and make attacks expensive.
Frequently asked questions
What hardware is used for mining?
ASICs for some chains and GPUs for others. The choice depends on the algorithm.Is solo mining viable?
Rarely for major chains. Mining pools help smaller operators earn more consistent rewards.What are the main costs?
Energy, hardware, maintenance, and cooling. Profitability changes with price and difficulty.
