Abstract

The Digital Product Passport (DPP), introduced by the European Green Deal in 2022, is a key innovation designed to improve product sustainability and circularity by enabling secure and transparent communication among stakeholders. Despite its potential, existing blockchain-based implementations of the DPP face significant limitations, such as scalability challenges and usability issues, which hinder widespread adoption. To address these shortcomings, this paper proposes a hybrid blockchain-based implementation of the DPP that enhances data transparency, integrity, and accessibility while minimizing common drawbacks. The proposed solution utilizes a hybrid blockchain architecture, where data is collected and managed within a private blockchain network and notarized on a public blockchain. Additionally, the central problem of authenticated blockchain data visualization is addressed by proposing a new solution that not only ensures the provenance, integrity, and history consistency of DPP data, but also preserves these properties throughout data processing and visualization. Our experiments demonstrates the effectiveness of our approach, achieving low time consumption and storage overhead. To further promote transparency and collaboration, a selection of the implementation has been made available as open-source projects. We show that hybrid blockchains offer a promising path for realizing the full potential of the Digital Product Passport.

期刊介绍： Computer and Communications networks are key infrastructures of the information society with high socio-economic value as they contribute to the correct operations of many critical services (from healthcare to finance and transportation). Internet is the core of today''s computer-communication infrastructures. This has transformed the Internet, from a robust network for data transfer between computers, to a global, content-rich, communication and information system where contents are increasingly generated by the users, and distributed according to human social relations. Next-generation network technologies, architectures and protocols are therefore required to overcome the limitations of the legacy Internet and add new capabilities and services. The future Internet should be ubiquitous, secure, resilient, and closer to human communication paradigms. Computer Communications is a peer-reviewed international journal that publishes high-quality scientific articles (both theory and practice) and survey papers covering all aspects of future computer communication networks (on all layers, except the physical layer), with a special attention to the evolution of the Internet architecture, protocols, services, and applications.
