During the upgrading process, there may be code defects, vulnerabilities, and even hacker attacks, which could threaten the security and stability of the entire blockchain network. In addition, technical difficulties and consensus disputes that may occur during the upgrading process could also trigger blockchain forks, leading to community division and asset depreciation. Therefore, when conducting blockchain upgrades, these risks must be fully considered and appropriate measures taken to ensure the smooth progress of the upgrade."}]}]}
