[Vitalik Proposes Introducing Transaction Simulation Mechanism to Enhance Ethereum Security and User Experience] According to Deep Tide TechFlow on February 23, as reported by Cointelegraph, Ethereum co-founder Vitalik Buterin suggested on the X platform on Sunday that mechanisms such as 'transaction simulation' could be introduced to improve the security and user experience of Ethereum wallets and smart contracts. Vitalik believes that security and user experience are not independent domains; both revolve around user intent, with the core being to ensure that the operations executed by the protocol align with user expectations. His proposed 'intent security' solution includes allowing users to view the simulated results of an operation before executing it on-chain, giving them the option to confirm or cancel. Additionally, mechanisms such as spending limits and multi-signature approvals could be introduced, permitting execution only when user intent, expected results, and risk constraints align. This would lower the threshold for low-risk operations while increasing the difficulty of executing high-risk operations. Vitalik also pointed out that defining user intent itself is 'extremely complex,' which is the fundamental reason why a 'perfect security' solution does not exist. It is not due to flaws in machines or designers but because user intent itself is a complex concept that even users may find difficult to clearly articulate. He stated that the common characteristic of excellent security solutions is enabling users to express their intent in multiple mutually corroborative ways, with the system executing operations only when these expressions are consistent.
