Mining plays a significant role in the blockchain, as  it can ensure the security and stability of the blockchain while also facilitating the generation of new coins. During the mining process, miners need to configure specialized mining machines and perform calculations according to specific algorithms. In the early days, Bitcoin mining could be done using a computer's CPU, but now Bitcoin mining has entered the era of ASIC mining and large-scale cluster mining. Miners submit their calculation results to the blockchain network to verify transactions and create new blocks."}]}],"pr":"b40a9d386e9012bb936b918d15e2a4b6529df7c68640fb8ee69c18498e4adc15"}
