Vitalik published an article outlining the development blueprint for the ideal crypto wallet, focusing on cross-L2 transactions and privacy protection

ChainCatcher message, Ethereum co-founder Vitalik Buterin published a latest blog post detailing his vision for the ideal crypto wallet. The article focuses on security and privacy, proposing key features such as cross-L2 transaction experience, account security, fraud prevention, and data wallets.Regarding cross-L2 transactions, Vitalik suggests adopting chain-specific address formats (e.g., address@optimism.eth) and recommends that wallets automatically handle cross-chain exchanges and transfer processes. For account security, he advocates for social recovery and multi-signature mechanisms, proposing a 2-of-3 protection scheme for new users, which includes zk-email, local keys, and service provider backup keys.On privacy protection, the article emphasizes the need to integrate features like 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. The article also explores secure chain access mechanisms, recommending the enhancement of wallet security through light clients and private information retrieval (PIR) technology, and calls on developers to adopt on-chain content version control to improve DApp security.

Wang Feng: Blueport Interactive strategically holds Bitcoin and will disclose tactical reduction progress in a timely manner

ChainCatcher news, Wang Feng, the founder of Blueport Interactive, stated on his X platform: "Why did Blueport Interactive buy Bitcoin, and what’s next? I will answer five points here:Our holding of Bitcoin is strategic. We are optimistic about Bitcoin network applications, decentralized finance, and empowering real assets and crypto assets aimed at Web3 applications.I am a fervent believer in crypto technology and have launched Marsbit, Consensus Lab (LK Venture), Mars Cloud Mining, and Element over the past five years. After regaining the CEO position in the first quarter of last year, I have vigorously promoted the integration of Blueport Interactive with Web3 business attempts.I am pleased that today Bitcoin has reached a new level close to $90,000, with our first purchase price at $26,000, followed by subsequent purchases. I first advocated for Blueport Interactive to buy Bitcoin when it was over $4,000, but at that time it was difficult for our board to execute.We will inevitably disclose the progress of linear reduction at the appropriate time; crypto assets, like stocks, have a market norm of volatility, and any reduction is tactical; if there is a reduction today, it must be for an increase tomorrow.We are long-term optimistic about Bitcoin; and we are very optimistic about the possibility of significant growth within this year or the first quarter of next year."
