According to TechFlow, on December 3, Ethereum co-founder Vitalik Buterin published a new blog post detailing his vision for an ideal crypto wallet. The article focuses on security and privacy, and proposes key features such as cross-L2 transaction experience, account security, fraud prevention, and data wallets.
In terms of cross-L2 transactions, Vitalik proposed the use of chain-specific address formats (such as address@optimism.eth), and suggested that wallets automatically handle cross-chain exchange and transfer processes. In terms of account security, he recommended the use of social recovery and multi-signature mechanisms, and the use of a 2-of-3 protection solution for new users, including zk-email, local keys, and service provider backup keys.
Regarding privacy protection, the article emphasizes the need to integrate features such as privacy pools and stealth addresses directly into mainstream wallets to achieve default privacy. In terms of data storage, Vitalik suggests that wallets evolve into personal data storage tools, using an M-of-N key sharing mechanism to protect user data.
Looking to the future, Vitalik predicts that new technologies such as AI and brain-computer interfaces will fundamentally change the way wallets interact. He specifically mentioned that through natural language input and analysis of user historical data, AI can accurately understand user intentions and automatically plan on-chain operations, while providing proactive security protection.
The article also explores secure chain access mechanisms, suggesting enhancing wallet security through lightweight clients and private information retrieval (PIR) technology, and calling for developers to adopt on-chain content version control to improve DApp security.
