Bitcoin mining is the process of verifying Bitcoin transactions and adding them to the blockchain by solving complex mathematical problems on computers. This process involves solving mathematical puzzles, known as "proof of work," to ensure that transactions on the network are verified and secure. Miners create new Bitcoins by solving these problems, and they are also rewarded with transaction fees.
Bitcoin mining requires a lot of computing power and electricity, so specialized hardware devices such as ASIC (Application Specific Integrated Circuit) miners are usually used. The mining process is competitive, because only the first miner who successfully solves the problem can add the new block to the blockchain and receive a Bitcoin reward.
