VeriZK: Zero-Knowledge Sybil Shield

Legacy identity checks force platforms to invasively hash raw passport data, creating privacy liabilities and breaking down when users hold multiple government IDs. VeriZK replaces fragile document scraping with zero-knowledge proofs that cryptographically attest human uniqueness without exposing PII, giving users portable control while permanently eliminating sybil accounts.

It's certainly not perfect. But it reduces the possibility of sock puppet accounts significantly.If you register (just with
