Move for Solidity Developers I: Storage and Access Control

This developer-focused guide contrasts Solidity/Ethereum with Move (Aptos and Sui), explaining how storage shifts from contract-centric mappings to Move resources in accounts or object-centric data in Sui, and how access control is implemented via signers, capability resources, and object ownership rather than ad-hoc msg.sender checks. It provides practical analogies and patterns to help Solidity developers adopt Move's resource-oriented and object-oriented paradigms.
