Identity as a cryptographic proof, not a registry entry or platform account.
No registry, no ledger, no central authority. Pure cryptographic identity using only Ed25519 + SHA-256.
Verify identity proofs anywhere, anytime without internet access. Complete independence from external services.
Create identities instantly. No registration, no approval, no gatekeepers. Truly open and decentralized.
Autonomous agents are first-class participants. Designed for AI from the ground up, not bolted on.
Algorithm agility and post-quantum migration path. ML-DSA support by 2027 for quantum resistance.
Production-ready libraries in Python and JavaScript. Clear specs, test vectors, and comprehensive docs.
Next-generation cryptographic capabilities for privacy, security, and flexibility
Prove identity possession without revealing it. Anonymous authentication, selective disclosure, and privacy-preserving credentials using Halo2 and STARKs.
View Specification →M-of-N multi-party control using FROST. Organizational identities, social recovery, and fault-tolerant agent systems without single points of failure.
View Specification →Cryptographically signed trust assertions. Build reputation systems, delegation, certifications, and web-of-trust networks on top of SGAIP.
View Specification →SGAIP v2 with multi-algorithm support. Seamless migration from Ed25519 to ML-DSA (post-quantum) and beyond. Hybrid mode during transition.
View Specification →24-month transformation plan: Security hardening → Quantum resistance → Production deployment
