Blockchain technology is a key enabler of trusted, transparent, and collaborative circular supply chains. Within CIRCULOOS, it supports secure data sharing between stakeholders, helping SMEs transition from linear to circular manufacturing models. This training introduces the fundamentals of blockchain and explains its role in building trust across organisations, a critical requirement for circular economy ecosystems.
By completing this training, you will:
- Understand the core principles of blockchain technology
Gain a clear understanding of how blockchain works, including key concepts such as decentralisation, distributed ledgers, immutability, and consensus mechanisms. You will be able to explain these concepts in a business and industrial context, not just technically. - Identify when blockchain is relevant for industrial use cases
Learn to assess whether blockchain is the right solution for a given scenario. You will understand the conditions where blockchain adds value (e.g. multi-stakeholder environments, lack of trust, need for transparency) and when alternative technologies may be more appropriate. - Recognise how blockchain builds trust across organisations
Understand how blockchain enables secure, transparent data sharing among independent actors without a central authority. You will explore how this trust layer is critical for collaboration across supply chains and ecosystems. - Discover how blockchain supports circular manufacturing in CIRCULOOS
Explore how blockchain is applied within the CIRCULOOS project to enable traceability, trusted data exchange, and collaboration between SMEs. You will understand its role in supporting circular strategies such as reuse, remanufacturing, and recycling within dynamic supply chains.
Blockchain is a foundational technology for enabling secure, transparent, and decentralised collaboration in circular supply chains. In CIRCULOOS, it ensures that data shared across stakeholders is trustworthy, traceable, and tamper-proof, enabling new circular business models.
This video introduces how blockchain has evolved from cryptocurrencies like Bitcoin into a powerful tool for business and industrial applications, enabling secure data sharing and collaboration across supply chains. You will learn the core concepts of blockchain, including decentralisation, immutability, and consensus, and understand their practical implications for real-world use cases. The video also explains how blockchain creates trust between organisations without intermediaries, allowing actors to collaborate securely even in low-trust environments.
Importantly, it helps you assess when blockchain is the right solution, and when simpler technologies may be more appropriate. Finally, you will explore how blockchain supports circular economy ecosystems, enabling transparent tracking of materials, verification of sustainability claims, and trusted collaboration between stakeholders.
