Taking Bitcoin  as an example, its proof-of-work (PoW) consensus algorithm requires miners to calculate and obtain hash values that meet specific difficulty levels. This process consumes a large amount of electricity. According to research, the electricity consumption required for Bitcoin mining has exceeded many countries, producing a negative impact on the environment."}]}],"pr":"28da3718e67592d1235e30572659538232ac61f4c0ffad645c107f322bf4c1f8"}
