What is a cryptocurrency miner

 

A cryptocurrency miner is a device or software that performs the process of mining, which involves using computing power to solve complex mathematical problems that validate and secure transactions on a blockchain network.

When a miner successfully solves one of these problems, it earns the right to add a new block of transactions to the blockchain and is rewarded with newly created cryptocurrency and transaction fees. This process ensures the network remains decentralized, secure, and continuously updated, while also controlling the release of new coins into circulation.
