Vitalik: Zero-knowledge proof of identity still has risks

Planet Daily News: Ethereum co-founder Vitalik Buterin wrote an article titled "Do Digital Identities Still Pose Risks Even After ZK Wrapping?", pointing out that: ZK-wrapping solved many important issues, but zero-knowledge proof identity verification still carries risks. These risks seem unrelated to biometric identification, and most risks (privacy leakage, vulnerability to coercion, errors) stem from attempts to maintain the "one person, one identity" attribute. The other extreme is using "wealth proof" to prevent Sybil attacks, but this is insufficient in many use cases. Therefore, something "ID-like" is needed. The theoretical ideal situation would be between these two approaches, which is difficult to achieve in practice. However, the correct "multi-identity" approach is close to the goal and thus represents the best practical solution. Multi-identity can be explicit (such as based on social graphs) or implicit (various types of zero-knowledge proofs, where no single type's market share can approach 100%).
