Blockchain for Decentralized Identity

In this series called “Blockchain for Decentralized Identity”, I start by explaining the concept of Self-Sovereign Identity (SSI) and its architecture aligned with Trust Over IP. Following that, I expand on each of the layers of the architecture and the standards. Next, I cover the Public Sector with a focus on progress in the EU. Following these, I expand on use cases: Travel, Healthcare, RegTech, NFTs, Social Innovation, the Enterprise, and Education. The Experiences to deliver these use cases use a digital smart agent that enables privacy and trust in the ecosystem. Finally, I close with the Adoption of SSI in the public and private sectors and the Art of the Possible covering the possibilities ahead.

These are intended for people on their journey to implement Self-Sovereign Identity and for those who would like to do more research on the topic. Each subsequent blog post builds on the ideas and concepts of the previous one, hence I would suggest that you read them in the sequence posted. In each section, refer to the Glossary for an explanation of terms and References at the end.
