[Vitalik Proposes Introducing Transaction Simulation to Enhance Ethereum Security] Ethereum co-founder Vitalik Buterin recently suggested on the X platform that features like 'transaction simulation' could improve the user experience and security of Ethereum wallets and smart contracts. He proposed that users could first specify their intended on-chain actions and then decide to 'confirm' or 'cancel' after reviewing the transaction simulation results. Additionally, he recommended introducing mechanisms such as spending limits and multi-signature authorizations to ensure alignment between user intent, expected outcomes, and risk limitations, thereby reducing the likelihood of high-risk operations. However, he also pointed out that defining user intent is extremely complex and achieving 'perfect security' is impossible, calling for multiple methods to verify user intent to enhance system security. Security is one of the 'blockchain trilemma' challenges, alongside decentralization and scalability, which are equally critical. In recent years, the Ethereum ecosystem has focused more on decentralization and scalability, particularly the latter. Earlier reports indicated that Vitalik had advocated for using personal LLMs to improve the efficiency of decentralized governance.
