Blockchain as value exchange

In circular manufacturing ecosystems, trust is not only about the data being shared, but also about the identity of the actors behind that data. Knowing who provides information, and being able to verify it, is essential for enabling collaboration across complex supply chains.

Self-Sovereign Identity introduces a new approach where organisations and individuals can own, manage, and control their digital identity without relying on central authorities. This ensures more secure, privacy-preserving, and trustworthy interactions. Within CIRCULOOS, SSI is integrated as part of a broader trust framework, aligned with European initiatives, to enable decentralised and reliable identity management across all stakeholders.

🧩Learning objectives

By completing this training, you will develop a clear understanding of what Self-Sovereign Identity (SSI) is and why it is becoming essential in digital ecosystems. You will learn how key components such as Decentralised Identifiers (DIDs), Verifiable Credentials, and digital wallets work together to give organisations control over their identity and data.

Throughout the module, you will also discover how trusted identity enables secure collaboration between multiple stakeholders, and how SSI can be applied within circular manufacturing environments to support reliable data exchange and stronger ecosystem trust.

🧩What you will learn from the video?

This video introduces the concept of Self-Sovereign Identity and explains how it shifts identity management from centralised platforms to user-controlled systems. You will understand how blockchain supports this model by providing a trusted infrastructure for identity verification, without exposing sensitive data.

The training walks you through the main building blocks of SSI, including decentralised identifiers, verifiable credentials, and verifiable presentations, showing how they interact within real-world identity flows. You will also learn how digital wallets give users control over their credentials, allowing them to decide what information to share, with whom, and under which conditions.

In addition, the video explains how identity is managed לאורך its lifecycle, including issuance, verification, and revocation of credentials, which is essential for maintaining trust over time. Finally, it connects these concepts to circular economy ecosystems, demonstrating how trusted identity enables secure collaboration, data sharing, and coordination between multiple actors.

🧩 Training Material 

This presentation provides a deeper understanding of SSI concepts through clear diagrams and architecture explanations. It illustrates how identity flows work in practice and how SSI is implemented within the CIRCULOOS framework.
