According to Foresight News, 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 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 directly integrate features such as privacy pools and stealth addresses 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 ahead, Vitalik predicts that new technologies such as AI and brain-computer interfaces will fundamentally change the way wallets interact.
