The PoW algorithm disputes the right to record accounts by calculating complex mathematical problems. The larger the calculation volume, the higher the probability  of obtaining the right to record accounts. The advantage is good randomness and fairness, but the disadvantage is high energy consumption."}]}],"pr":"2b443606b35b68848cf9b7e6dc6d92885f2899682c06b009fff44b8974afdf39"}
