This module introduces key differences between Solidity and Move concerning state storage and access control. Solidity’s contract-centric storage contrasts with Move’s resource and object-centric models in Aptos and Sui, respectively. Access control in Move is enhanced through the use of signer types and capability resources, offering a robust framework for secure smart contract development. Understanding these distinctions is vital for developers transitioning to Move-based blockchains.
Q1: What is a primary difference between Solidity and Move's approach to access control?
A1: Move uses the signer type, while Solidity relies on msg.sender.
Q2: In Aptos Move, where is data primarily stored?
A2: Organized by accounts, with each holding specific resources.
Q3: How does Sui Move's storage model differ from Aptos Move's?
A3: Sui Move uses an object-centric model, while Aptos Move uses an account-based model.
Q4: What is the purpose of a "capability" in Move?
A4: To signify permission to perform certain actions.
