Virtual currency mining started with bitcoin. In a word,Bitcoin mining is the process of creating new bitcoin by solving a computational puzzle.

On January 3, 2009, the founder of bitcoin, Nakamoto Tsung, personally created the first block, that is, the genesis block of bitcoin, and won the first 50 bitcoins automatically generated by the system. The first bitcoin came out.

Bitcoin mining is performed by high-powered computers that solve complex computational puzzle; these problems are so complex that they cannot be solved by hand.

From the perspective of the output mechanism of bitcoin, the miner calculates the "mathematical problem" of the block in the bitcoin network through calculation. Whoever solves the block first can get the bookkeeping right of the block and get the bitcoin reward in the block, and the miner will be born.
