币界网报道：Ethereum co-founder Vitalik Buterin has outlined his vision for integrating privacy features with digital identity solutions in a recent blog post. Buterin emphasized the need for a "privacy-first" approach to digital identity, proposing a system where users can selectively disclose personal information without revealing their entire identity. He highlighted the potential of zero-knowledge proofs (ZKPs) as a key technology to enable this functionality, allowing verification of credentials without exposing underlying data. The Ethereum creator also discussed the limitations of current identity systems like Worldcoin's iris-scanning approach, noting they often sacrifice privacy for uniqueness. Buterin suggested combining biometrics with smartphone-based solutions could offer better privacy protections while maintaining security. He pointed to existing projects like Ethereum's own Sign-In with Ethereum (SIWE) and various decentralized identity (DID) systems as promising foundations. The blog post comes as governments worldwide are developing digital identity frameworks, with Buterin warning against centralized models that could enable surveillance. Instead, he advocated for decentralized, user-controlled identity solutions that leverage blockchain technology's transparency while preserving individual privacy through cryptographic techniques. Buterin's proposals aim to address growing concerns about data privacy in an increasingly digital world, where identity verification is required for everything from financial services to social media platforms. The Ethereum founder's vision aligns with broader Web3 principles of user sovereignty and data ownership, potentially positioning blockchain-based identity solutions as alternatives to traditional systems controlled by corporations and governments.
