1) Account model: In most Ethereum ERC-20 contracts, the balance of each address is stored in a state variable of type , while Move’s global storage is indexed by address;
2) Code storage: In EVM-based chains, all smart contracts have a "contract owner address", while in MoveVM-based chains, the code is stored in the code module of the Account resource;
3) Security isolation: Move makes blockchains using the Move language deterministic through MoveVM, and places contract calls in the same virtual machine sandbox, isolating them through the internal security of the programming language rather than relying on the virtual machine;
4) Contract upgrade: Move executes the upgrade logic in the system module code.move.
