Mining Ashing Process

The process of mining bitcoins is similar to a lottery.Bitcoin miners are competing to produce hashesalphanumeric strings of fixed length that are calculated from data of an arbitrary length.They are producing the hashes from a combination of three pieces of data: new blocks of bitcoin transactions; the last block on the blockchain; and a random number.
