A New Paradigm for On-Chain Identity_ DIDs, Verifiable Credentials, and the Reconstruction of Web3 Trust
Blockchain
In the digital world, "identity“ has long been treated merely as a login tool, while the power structures and trust mechanisms behind it were rarely examined. As Web3, decentralized finance, and on-chain governance continue to evolve, identity is no longer just a key for system access—it now carries credit, permissions, and value distribution. This course starts from that fundamental shift and guides you to rethink the evolving role of identity in digital society, exploring how decentralized identity becomes a critical foundation for rebuilding trust in Web3.
About the Course
This course provides a systematic introduction to how Decentralized Identity (DID) and Verifiable Credentials (VCs) are constructed, verified, and applied on-chain, and how they reshape trust models in Web3. Key topics include: The structural evolution of identity from Web2 to Web3; the technical architecture and standards behind DIDTrust models and privacy mechanisms of verifiable credentials; real-world applications of on-chain identity in DeFi, DAOs, compliance, and cross-platform ecosystems. Rather than focusing solely on how identity works, the course emphasizes why identity matters—helping you understand how identity evolves from a simple login mechanism into a sustainable, manageable, and verifiable trust foundation, and why it will become an indispensable component of Web3 infrastructure.
