Bitcoin mining is the process by which new bitcoins are created and transactions on the blockchain are verified and processed. Miners use specialized hardware, called ASICs (Application-Specific Integrated Circuits), to solve complex mathematical problems. When a miner solves a problem, a new block is added to the blockchain and the miner is rewarded with a certain amount of bitcoin. The difficulty of these problems adjusts dynamically to ensure that a new block is created roughly every 10 minutes. The process of mining helps secure the blockchain and provides the computational power needed to process transactions.
