Self-sovereign identity and decentralized authentication solutions

Technologies

Verifiable credentials create tamper-proof, portable digital attestations. Zero-knowledge proofs enable verification without revealing underlying data. Decentralized identifiers (DIDs) provide self-controlled identity anchors. Biometric authentication adds security to decentralized identity. Identity wallets store and present credentials across services.

Applications

Digital identity wallets store government IDs, educational credentials, and professional certifications. Zero-knowledge age verification proves age without revealing birthdate. Verifiable employment credentials enable background checks without centralized databases. KYC verification using reusable identity attestations.

Market and funding

Decentralized identity enables self-sovereign digital identity where individuals control their own identity data using cryptographic proofs. With 2 funders.
