Vitalik proposed introducing transaction demo functionality to improve Ethereum's security.

PANews reported on February 23 that Ethereum co-founder Vitalik Buterin recently suggested on the X platform that features such as "transaction simulation" be used to improve the user experience and security of Ethereum wallets and smart contracts. He proposed that users could first specify their on-chain operation intentions, and then choose to "confirm" or "cancel" by viewing the transaction simulation results.

In addition, he suggested introducing mechanisms such as spending limits and multi-signature authorization to ensure consistency between user intent, expected results, and risk constraints, thereby reducing the likelihood of high-risk operations. However, he also pointed out that the definition of user intent is extremely complex, making "perfect security" impossible, and called for multiple methods to verify user intent to improve system security.

Security is one of the "blockchain trilemma," ranking alongside decentralization and scalability as a key challenge. In recent years, the Ethereum ecosystem has focused more on decentralization and scalability, especially the latter.

Previously, Vitalik proposed using personal LLMs to improve the efficiency of decentralized governance .
