Wu said that Ethereum co-founder Vitalik Buterin published a latest blog post, detailing the future development trends and challenges of Ethereum wallets: focusing on analyzing challenges and solutions in multiple dimensions such as user experience, security, privacy protection, and technology integration. Core summary: 1. User experience improvement: Focus on cross-L2 transactions, simplify the operation process through built-in cross-chain sending and chain-specific addresses, optimize the gas payment experience, provide standardized payment request methods, and achieve more efficient payment through QR codes or on-chain addresses; 2. Account security and guardianship mechanism: Introduce multi-signature and social recovery functions, combine hierarchical access control, improve account security, and explore centralized identity solutions based on ZK-SNARK; 3. Privacy protection and data management: Integrate privacy transfers into mainstream wallets, combine privacy pool technology to achieve separation of assets and identities, support off-chain data storage, so that wallets not only manage on-chain assets, but also are responsible for users' private data; 4. Technical improvement and security: Emphasize that wallets need to support light client technology, improve data security by verifying blockchain consensus, encourage on-chain content version control, and reduce users' risks caused by insecure Web2 interfaces; 5. Future trends: With the development of AI, brain-computer interfaces and active defense technologies, wallets will shift from traditional interfaces to more intelligent and intuitive interaction modes; AI It will play a more important role in user interaction, helping users complete on-chain and off-chain operations through natural language processing and historical data analysis.
