This process helps to ensure the integrity and consistency of the blockchain while generating new coins. Mining originated from Bitcoin, where initially only computer CPUs were needed for calculation. However, as mining difficulty increased, we have now entered  the era of ASIC mining and large-scale cluster mining. Miners connect their mining equipment to the blockchain network, calculate through specific algorithms, write transaction data into the blockchain, and thereby receive virtual currency rewards. These virtual currencies can be cashed out on online trading platforms."}]}],"pr":"2b88d51da604d3a9112f06e3f8519292236e0e6d1bb9b73172d0e17f500ad0b0"}
