Vitalik proposes transaction simulation function to enhance Ethereum security and experience

On February 23rd, Vitalik, co-founder of Ethereum, proposed to enhance the user experience and security of Ethereum wallets and smart contracts through transaction simulation. Users can specify on chain operation intentions and choose to confirm or cancel after viewing the simulation results. In addition, he suggested introducing mechanisms such as expenditure restrictions and multi signature authorization to reduce the possibility of high-risk operations, but pointed out that the definition of user intent is complex and cannot achieve perfect security, requiring multiple ways to verify user intent. Security is one of the "impossible triangles" of blockchain, alongside decentralization and scalability as key challenges. In recent years, the Ethereum ecosystem has focused more on decentralization and scalability.
