Why Is Identity Verification a Challenge for Decentralized Sybil Resistance?

Decentralization is fundamentally rooted in pseudonymity and censorship resistance, making it difficult to enforce a "one-person, one-vote" rule without compromising user privacy. Requiring traditional identity documents introduces a central point of failure and potential for surveillance or censorship.

Creating a robust, decentralized, and privacy-preserving identity system that is also Sybil-resistant is an unsolved problem in the Web3 space.
