Vitalik proposes introducing a transaction simulation mechanism to improve the security and user experience of Ethereum

ChainCatcher reports that, according to Cointelegraph, Ethereum co-founder Vitalik Buterin posted on X platform on Sunday, suggesting improvements to Ethereum wallet and smart contract security and user experience through mechanisms such as “transaction simulation.”

Vitalik believes that security and user experience are not mutually exclusive domains; both revolve around user intent, with the core being to ensure that protocol operations align with user expectations. His proposed “intent security” solution includes: allowing users to preview the simulation results of on-chain actions before executing, then choosing to confirm or cancel; additionally, mechanisms such as spending limits and multi-signature approval can be introduced, permitting execution only when user intent, expected outcome, and risk limits are aligned, thereby lowering the threshold for low-risk operations while increasing the difficulty of executing risky ones.

He also points out that defining user intent is inherently complex, which is the fundamental reason why perfect security solutions do not exist. It is not a flaw in machines or designers, but because user intent itself is a complex object that even users find difficult to clearly grasp. He states that the common feature of excellent security solutions is enabling users to express their intent through multiple mutually corroborating methods, with the system only executing operations when these expressions are consistent.
