Ridvn

Ridvn is a decentralized identity protocol and data-exchange framework designed to give individuals control over personal information while enabling verifiable and privacy-preserving exchanges across institutions. It specifies a set of standards for self-sovereign identity, including verifiable credentials, decentralized identifiers (DIDs), and consent-driven data sharing. The project is organized by the Ridvn Foundation, a non-profit that coordinates open-source development and interoperability efforts.

The project originated in proposals in the early 2020s and released its first public protocol specification in 2022. It has since been adopted in several pilot programs in education, healthcare, and public services to test credential issuance, revocation, and portable identity wallets.

Ridvn emphasizes user-centric privacy. It supports selective disclosure, meaning a user can reveal only the necessary attributes from a credential. It also supports offline verification and lightweight cryptographic proofs to minimize data exposure. The reference implementations are available in multiple languages and aim to be interoperable with other DID ecosystems.

Core architecture comprises three roles: the holder (user wallet), issuer (organization that issues credentials), and verifier (service requesting verification). Credentials are stored as portable, cryptographically verifiable data objects tied to a decentralized identifier, with a governance layer to manage schema and revocation.

Usage examples include digital identity verification for services, age or eligibility checks, and secure health data exchange. Governance is conducted by the Ridvn Foundation with community input, aiming for open standards and cross-Platform interoperability. The project has garnered interest from privacy advocates and policymakers, though interoperability and regulatory alignment remain ongoing challenges.
