Self - Future Proof Security
Verify your digital identity seamlessly and securely.
Self.xyz is a privacy-first, open-source identity verification protocol that uses zero-knowledge proofs (zk-SNARKs) to enable secure and private digital identity verification. It allows users to prove attributes about themselves—such as being a real human, being over a certain age, or being from a specific country—without revealing sensitive personal data. Users scan their biometric passports or government-issued ID cards using an NFC-enabled phone, and Self.xyz verifies the authenticity of the documents through encrypted signatures embedded in the chips. The protocol then generates zero-knowledge proofs that can be selectively shared with applications, confirming identity claims without exposing private information like names or passport numbers.
Key features include strong Sybil resistance, ensuring one person can only have one verified identity, which helps prevent fraudulent multiple registrations common in token airdrops and decentralized governance. It empowers users with decentralized, portable digital identities they control, rather than relying on centralized databases. The protocol operates in three steps: scanning the passport, generating a zk-proof from the passport data, and sharing the proof with the intended app or service.
Self.xyz also supports various use cases such as age verification without revealing exact birthdates, compliance with DeFi regulations based on nationality, protection from AI bots by verifying real human users, wallet recovery mechanisms using identity proofs, and ensuring fairness in token distributions. Unlike some protocols requiring special biometric hardware, Self leverages existing government-issued identification and NFC technology, making it accessible and trusted by existing infrastructures.
In summary, Self.xyz provides a secure, privacy-preserving digital identity solution that balances user control, compliance, and fraud prevention through advanced cryptography and selective disclosure, making it suitable for Web3, DeFi, and digital human verification needs.
