Workshop: CREDEBL For Decentralized Identity and Verifiable Credentials
·OnlineOnline84 attendees from 166 groupsAs adoption of Decentralized Identity (DID) and Verifiable Credentials (VCs) accelerates across governments, education, enterprises, and regulated industries, developers and organizations need open, interoperable, and production-ready infrastructure to build trusted digital ecosystems.
This webinar introduces CREDEBL, an LF Decentralized Trust project, and walks participants through how to get started quickly, understand the architecture, and explore real-world use cases - all backed by open standards and community-driven development.
Whether you are a developer, architect, policy stakeholder, system integrator, or ecosystem partner, this session will help you move from concepts to implementation.
What We’ll Cover
- The Problem: Fragmented Digital Trust : Why identity, credentials, and verification remain siloed - and how this limits interoperability, privacy, and adoption.
- The Foundation: Verifiable Credentials & Decentralized Identity : A brief overview of DIDs, VCs, DIDComm, OID4VC, trust frameworks and where CREDEBL fits within the LFDT ecosystem.
- The Platform: CREDEBL Architecture : Core components, issuer–holder–verifier flows, APIs, and deployment models.
- Getting Started Fast: One-Click / Minimal-Config Setup : Live walkthrough of setting up CREDEBL and running end-to-end credential flows.
- Live Demo: Issuance & Verification in Action : Creating DIDs, issuing credentials, wallet interactions, and verification scenarios.
- Real-World Adoption & Ecosystem Use Cases : Education, digital identity, enterprise and public-sector use cases.
- Community, Governance & Roadmap : Open-source contribution model, roadmap, and how to get involved with the CREDEBL and LFDT community.
