In a blockchain network, nodes need to perform extensive calculations and data verification, resulting in increased energy consumption. Particularly in public blockchain networks such as Bitcoin, miners compete to solve complex mathematical problems to receive  new block rewards. This mining process consumes a large amount of energy, and according to statistics, the energy consumption of Bitcoin mining has already exceeded that of many countries."}]}],"pr":"c64480c5d60ca8862b4c2751361eff9b5fb40ba009c7de349e54cd4552499caf"}
