Vereign

Vereign is a Swiss-based digital identity company founded in 2017 that develops Self-Sovereign Identity (SSI) solutions focused on authentic communication and document verification.

The platform's main components include the Vereign Vault for organizations to manage verifiable credentials, the Vereign Wallet for individual users to store credentials and documents, and Web3 Digital Twins for email and document authenticity. The system implements the W3C Verifiable Credentials Data Model and integrates with common email clients through browser extensions and add-ins for platforms like Microsoft Outlook and Gmail. Key technical features include:

• End-to-end encryption and key management through hardware security modules
• Integration with IPFS for decentralized storage
• Support for multiple DID methods and credential formats
• Zero-knowledge proofs for privacy-preserving verification
• Built on Open Source components including Hyperledger and LibreOffice

The company has positioned itself as a contributor to the European Gaia-X initiative and developed components for the Gaia-X Federation Services. Notable implementations include integration with VNC for secure email traffic and collaboration with DAASI International on SSI technology for Gaia-X. Vereign emphasizes user control and data sovereignty while maintaining compliance with regulations like GDPR through its federated network architecture.
