If we want to simplify that, blockchain is a copybook that has so many pieces in different locations but all these pieces are connected with a net.

What is Mining?

Mining is the method must be used to earn cryptocurrency. In mining, specials devices are used to solve complex cryptographic problems. In theory, everyone with a computer and internet connection, can mine. After mining, systems used in blockchain verifies the transaction. Finally, if the transaction is proper, it gets recorded in the blockchain. Also graphic cards of computers can be used to do mining. The higher the power of the card, the higher the efficiency is.
