Crypto miner

A crypto miner is a participant in a proof-of-work blockchain network who uses computing power to compete to produce valid blocks under a protocol’s established rules. Miners collect unconfirmed transactions, assemble them into candidate blocks, and then perform computational work to find a valid block hash that meets the network’s difficulty target. Once a miner succeeds in producing a valid block that is accepted by the network, that block becomes part of the blockchain’s transaction history. Mining is part of how a proof-of-work network achieves consensus, orders transactions, and makes it costly to rewrite prior blocks.

For example, miners compete to add the next Bitcoin block roughly every 10 minutes by performing proof-of-work. The miner who produces an accepted block earns the block reward under Bitcoin’s protocol rules.
