What Is Bitcoin Mining?

Bitcoin mining is the process that secures the Bitcoin network and adds new blocks to the blockchain. Miners use specialized computers to compete for the right to create the next block. The winner earns bitcoin rewards and transaction fees. --- ## What miners actually do Miners gather transactions, build candidate blocks, and perform repeated hashing until they find a valid result. This process is called proof of work. It requires real energy and real hardware. That cost is what makes attacking Bitcoin expensive. --- ## Why mining matters Mining helps Bitcoin remain decentralized and secure. It prevents easy rewriting of transaction history. It also provides a fair process for issuing new bitcoin according to the network’s rules. --- ## Mining and new bitcoin New bitcoin enters circulation through block rewards. Over time, those rewards are reduced through events called halvings. Eventually, no new bitcoin will be issued, and miners will be paid mainly through transaction fees. --- ## Final takeaway Bitcoin mining converts energy into network security. It is how blocks are added, transactions are confirmed, and the system remains difficult to attack.
