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

Deep Tide TechFlow News, February 23 — 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 fields; 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 operations before confirming or canceling; additionally, introducing consumption limits and multi-signature approval mechanisms, so that execution is only permitted when user intent, expected results, and risk limits are all aligned, thereby lowering the threshold for low-risk operations while increasing the difficulty of executing risky ones.

He also pointed out that defining user intent itself is “extremely complex,” which is the fundamental reason why there is no “perfect security” solution. It is not due to flaws in machines or designers, but because user intent is inherently a complex object that even users themselves find difficult to clearly grasp. He stated 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.
