A Bitcoin miner is a specialized computer or device that validates and secures transactions on the Bitcoin network. It works by solving complex mathematical puzzles, a process called “proof of work,” which ensures that transactions are legitimate and prevents double-spending. In return for providing this computational power, miners are rewarded with newly created bitcoins and transaction fees. Modern Bitcoin mining often uses powerful machines called ASICs (Application-Specific Integrated Circuits), which are far more efficient than regular computers.
