            Abstract
            Delving into the design and implementation of a verifiable data registry (VDR) for decentralized identity and trust management in IoT environments. The authors utilize HyperLedger Fabric as the underlying blockchain infrastructure and xvi Preface introduce a novel hybrid consensus algorithm tailored for IoT networks. The chapter also details the creation of an efficient and secure VDR using gRPC services, emphasizing both security and scalability for IoT applications.
