During this period, to ensure the security and stability of the blockchain, validators can continue to perform routine block  validation and consensus processes. After the issues are resolved, validators can try upgrading again. Meanwhile, to prevent similar problems from occurring in the future, validators should also improve the upgrade process and system detection, enhancing the system's robustness."}]}],"pr":"baa63ac48849ff073b449bc98280dcaad035403d1663c81aa47277b41e29d2af"}
