The PoW mechanism requires a large amount of computing power and electrical resources, as miners compete to solve complex hash functions, thereby confirming transactions and generating new blocks. This leads to extremely high  energy consumption and carbon emissions, which is not conducive to sustainable development. However, to address these challenges, some solutions have been proposed, such as adopting new consensus mechanisms (such as Proof of Stake [PoS] and Proof of Authority [PoA]), renewable energy, as well as resource sharing and recycling, to reduce energy consumption."}]}],"pr":"97a62088f0fe0b6dae9cada1bbf006d2e5de06ba452477cb712718cd7df735fa"}
