The difficulty  of the problem will be automatically adjusted according to the total computing power of the network to ensure that the generation speed of blocks is approximately one every 10 minutes. However, PoW has some drawbacks, such as high energy consumption and centralization risks."}]}],"pr":"d6ae05bbd31a431d28fa3c06779afdf179cfcbed561d4076783a4c20ecbcc11f"}
