Many applications require identity verification, but traditional methods often involve sharing excessive personal data, creating privacy risks for users. Current solutions lack user control over what information is disclosed and can be vulnerable to Sybil attacks and bot manipulation.

Self provides a privacy-first identity verification protocol leveraging zero-knowledge proofs to allow users to prove attributes about themselves without revealing the underlying data. Users scan their passport using their phone's NFC reader, generate a zero-knowledge proof, and selectively disclose only the required information to the application. This approach enables Sybil resistance, protects against bots, and ensures compliance with regulations like sanction list checking, all while preserving user privacy. Developers can integrate Self into their applications with a few lines of code, using available SDKs and APIs.

Zero-knowledge proof generation from passport data via mobile app

Selective disclosure of verifiable credentials, such as age or nationality

Sybil resistance to prevent bot manipulation in airdrops and voting

Sanction list checking without exposing user data

React component for generating QR codes for easy integration

Backend SDK for verifying proofs on a node server or on-chain

Support for multiple platforms, including Web3 and universal apps

Open-source protocol, promoting transparency and community involvement

Self targets Web3 developers, social media platforms, and other applications requiring secure and privacy-preserving identity verification, as well as organizations seeking to implement Sybil-resistant governance and fair token distribution mechanisms.
