Mining is the process of adding transaction records to Bitcoin’s public ledger of past transactions.This ledger of past transaction is called the blockchain as it is a chain of blocks.The block chain serves to confirm transactions to the rest of the network as having taken place.Bitcoin nodes use the block chain to distinguish legitment Bitcoin Transactions from attempts to respend coins that have already been spent elsewhere.

Bitcoin mining is so called because it resembles the mining of other commodities; it requires exertion and it slowly makes new currency available at a rate that resemblem the rate at which commodities are like gold are mined from the ground.

The purpose of Bitcoin mining is to allow Bitcoin nodes to reach a secure ,tamper resistent consensus.
