Abstract :
This research presents an innovative system for managing access control and real-time data flow within a decentralized supply chain. Leveraging blockchain technology, specifically Hyperledger Fabric, in conjunction with IPFS for off-chain decentralized storage, this system facilitates real-time access to IoT network data by various supply chain participants. This real-time access enhances transparency, enables continuous quality control through monitoring, and ensures data security and immutability. The system introduces a novel access control scheme, R2-BAC, which integrates both role-based and rule-based approaches, offering flexibility in defining access levels. Furthermore, the system has been rigorously evaluated and tested under varying numbers of concurrent requests, demonstrating promising scalability and performance when compared to existing models.
