Mining is a Bitcoin record-keeping service that ensures fairness while keeping the Bitcoin network stable, safe and secure. Bitcoin miners help keep the Bitcoin network secure by approving transaction. Miners keep the block chain consistent, complete, and unalterable by repeatedly verifying and collecting newly broadcast transactions into a new group of transactions called a block. The new block must contain information that chains it to the previous block and gives the block chain its name. With Bitcoin, miners use special software to solve math problems and are issued a certain number of bitcoins in exchange. This provides a smart way to issue the currency and also creates an incentive for more people to mine.
