Bitcoin mining is done by specialized computers. The role of miners is to secure the network and to process every Bitcoin transaction. Miners achieve this by solving a computational problem which allows them to chain together blocks of transactions (hence Bitcoin's famous "blockchain").. For this service, miners are rewarded with newly-created Bitcoins and transaction fees.
