First, upgrades can enhance the chain's performance, such as increasing transaction speed and reducing confirmation time. Secondly, upgrades can strengthen the chain's security by introducing new security mechanisms and fixing known vulnerabilities to resist attacks. In addition, blockchain upgrades can optimize the consensus mechanism, improving the degree of decentralization and stability of the system. Meanwhile, upgrades can also improve the chain's scalability, supporting a wider range of application scenarios. However, the upgrade process may encounter challenges such as technical compatibility  issues and node splits, which could lead to chain forks. To ensure the smooth progress of the upgrade and maintain"}]}],"pr":"1549588f36666ec983a98d1d504e238f7fb1e9cf1cddc6afb575eba78006c793"}
