On different blockchain platforms, the specific implementation and name of permission flags may vary. However, their main purpose is to ensure the security and compliance of smart contracts, ensuring that only authorized participants can deploy and execute them.↵↵For instance, on the Ethereum platform, permission flags are usually reflected in the contract's access control mechanisms, such as permission lists and proxy permissions. Contract developers can define in the smart contract which accounts are allowed to perform operations on the contract, such as calling functions or viewing data. In addition, Ethereum also supports permission upgrades and dynamic permission control, allowing smart contracts to be more flexible and adaptable."}]}],"pr":"5259653c05ebacac62417062ad6e2e1faece5460f683956aa518ae5f45b205fc"}
