The PoW mechanism requires a large amount of  computing power and electrical resources, as miners compete to solve complex hash functions, confirm transactions, and generate new blocks. 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]), energy renewableization, and resource sharing and recycling, to reduce energy consumption and carbon emissions, and promote the sustainable development of blockchain technology."}]}],"pr":"29ebb2a8ebb019cf517edf3055aab58f4560593041fcff716d54c4f4776fc6e1"}
