According to TechFlow, on February 23, Cointelegraph reported that Ethereum co-founder Vitalik Buterin published an article on the X platform on Sunday, suggesting 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 fields; both revolve around user intent, with the core being ensuring that the actions executed by the protocol align with user expectations. His proposed "intent security" solution includes: allowing users to view a simulated result of an on-chain operation before confirming or canceling it; and introducing spending limits and multi-signature approval mechanisms, allowing execution only when the user's intent, expected result, and risk limits are consistent, thereby lowering the barrier to low-risk operations while increasing the difficulty of executing risky operations.
Vitalik also pointed out that defining user intent is "extremely complex," which is the fundamental reason why there is no "perfectly secure" solution. It's not that there are flaws in the machine or the designers, but rather that user intent itself is a complex object that even the user themselves finds difficult to clearly grasp. He stated that a common characteristic of excellent security solutions is that they allow users to express their intent in multiple mutually corroborating ways, and the system only performs the action when these expressions are consistent.
