If the transaction volume or the number of active users suddenly decreases, it may indicate an activity failure. In addition, analyzing indicators such as congestion level and transaction speed of the blockchain network can also help detect activity failures. Once abnormal situations are discovered, corresponding measures can be taken to investigate  and resolve them to ensure the normal operation of the blockchain network."}]}],"pr":"51b9b93123672668848fd23e24a1eb6941cc4c2331eaf758085451b4de351563"}
