Introduction. Mining is the process of adding transaction records to Bitcoinâs public ledger of past transactions. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place.itcoin uses the hashcash proof-of-work function.

Hail stones are much bigger than ice pellets that one sees in a sleet. Hail has been known to cause damage to crops and occasionally to drivers as they can break windshields of cars. You can understand how big and heavy a hail must be if it can break a windshield of a car.
