Decentralized Digital Product Passport Building Blocks for Enhancing Supply Chain Sovereignty and Circular Economy Practices

Year: 2025

Type: article

Abstract: This research article explores the decentralization of Digital Product Passport (DPP) building blocks for Asset Administration Shells (AAS), aiming to enhance the management and traceability of digital assets. The DPP system is conceptualized to incorporate three critical elements: identity management, traceability, and access permissions. We present a comprehensive architecture that integrates these elements, ensuring a resilient supply chain. Furthermore, we delve into the custodianship of the DPP data, examining the roles and responsibilities of various stakeholders in maintaining and securing the system. Finally, we experiment with existing technologies to conceptualize a decentralized DPP system for AASs, showcasing its practical application and effectiveness in real-world scenarios. This study sheds some light into the potential of decentralized systems in digital product management, highlighting the benefits and challenges associated with their deployment.
