Vitalik Proposes Introducing Transaction Rehearsal Feature to Enhance Ethereum Wallet and Contract Security and User Experience
On February 23, Ethereum co-founder Vitalik Buterin proposed enhancing the user experience and security of Ethereum wallets and smart contracts through features like "transaction simulation." Users would first specify their on-chain operation intent, then select "confirm" or "cancel" after reviewing simulation results.
Additionally, he suggested introducing mechanisms such as spending limits and multi-signature authorization to ensure alignment between user intent, expected outcomes, and risk mitigation—lowering the chance of high-risk operations. He also noted, however, that defining user intent is extremely complex and "perfect security" is unattainable, urging multi-method intent verification to strengthen system security.
Security is one of blockchain’s "impossible trilemma" alongside decentralization and scalability, all core challenges. In recent years, the Ethereum ecosystem has prioritized decentralization and scalability—particularly the latter.
