Abstract: An important issue in coopetitive supply chains is ensuring business confidentiality when sharing sensitive information among partner actors. This challenge becomes even more complex in blockchain-based supply chains due to inherent transparency, conflicting with businesses’ need to safeguard sensitive information and posing risks to proprietary data. In this paper, we propose an approach based on permissioned blockchains to support transactional business confidentiality in supply chains. The approach is implemented as an open-source platform and evaluated against five non-functional requirements.
