Self Protocol
Also appeared as Self
Self Protocol is a privacy-first, open-source identity protocol powered by zero-knowledge proofs. It enables developers to verify users’ identity and humanity (Sybil resistance, age, country, sanctions checks) without exposing private data. Participants can use Self to prove details like: 🙋♀️ Name 🔞 Age or age range 🚫 Not on the OFAC sanctions list With just a few lines of code via the Self.xyz SDK, proofs can be verified onchain (Celo) or offchain. Build trust into your project while keeping user privacy intact.
