STARS is a project funded by the European Union's COSME Programme which addresses all aspects related to the uptake of advanced technologies for the delivery of Railway-related innovations by SMEs. Approaching technologies such as Artificial Intelligence, Blockchain, Big data, Internet of Things, IT for Mobility, Cybersecurity, Advanced Manufacturing, Advanced materials, will boost competitiveness of our European SMEs towards the Railway & Multimodality meta-ecosystem, which is strategically important for the European Industrial Transformation and Resilience. STARS4TRACE is the service designed for STARS project which enables the railway SMEs to exchange digital assets representing physical goods in a way which promotes a transparent and auditable business. All the operations representing the SME's business processes are recorded on the network and they are digitally signed and sealed by a double layer infrastructure. The first layer is a distributed network relying on the Partners taking part in the project. The second one is a public blockchain which enhance data integrity. Both the networks are fully open for the connection and the inspection while preserving the privacy of the data of the partecipants.Many use cases are supported, from the KANBAN production model to the prototype development, but we foresee that new cases will arise during the development of the STARS project and the uptaking of the new technologies.
