Self: Prove who you are without sharing private information with third parties

Self is an open-source identity platform built on zero-knowledge proofs that lets people prove specific facts about themselves, such as being a unique human, being over a certain age, or not being on a sanctions list, without sharing their underlying documents or personal data. Users verify once by scanning the chip in a biometric passport or national ID with the Self mobile app, and the proof is generated on their device. Pre-KYC, Self's enterprise product, screens applicants for categorical eligibility before any billable KYC check is triggered, and the article says it stores no personal data for users who do not qualify. The article also states that Self completed a third-party security audit by zkSecurity.
