Vitalik Proposes Introducing Transaction Rehearsal Feature to Enhance Ethereum Wallet and Contract Security and User Experience

BlockBeats News, February 23rd, Ethereum co-founder Vitalik proposed to enhance the user experience and security of Ethereum wallets and smart contracts through features such as "transaction simulation." Users can first specify on-chain operation intent, and then choose "confirm" or "cancel" after viewing the transaction simulation results.

In addition, he also proposed introducing mechanisms such as spending limits and multi-signature authorization to ensure consistency among user intent, expected results, and risk mitigation, thereby reducing the likelihood of high-risk operations. However, he also pointed out that the definition of user intent is extremely complex and that "perfect security" cannot be achieved. He called for verifying user intent through multiple methods to enhance system security.

Security is one of the "impossible trilemma" of blockchain, along with decentralization and scalability, which are key challenges. In recent years, the Ethereum ecosystem has been more focused on decentralization and scalability, especially the latter.
