Mining Bitcoin involves using powerful computer hardware to solve complex mathematical problems that validate transactions on the Bitcoin network. Miners compete to find a valid solution to the cryptographic puzzle, and the first one to do so is rewarded with newly minted Bitcoins. This process is called proof of work. The miner then adds the validated transactions to the blockchain, which is a decentralized and distributed ledger of all Bitcoin transactions. This process requires high computational power and energy consumption, so miners often work together in mining pools to increase their chances of successfully mining Bitcoin and sharing the rewards.
