The Internet of Things (IoT) applications and services encounter several challenges that need to be addressed, encompassing both technological and social aspects. One significant obstacle is the need for a standardized Identification Scheme (IS) for the IoT ecosystems. Digital identities establish vital connections and relationships within the IoT ecosystem. The existing works still need to thoroughly address critical issues such as managing global identification systems, enhancing security, and encryption of identities, verifying authenticity, and maintaining directories for locating and discovering IoT applications and their unique identifiers. Blockchain technology, an innovative and transformative distributed ledger technology, presents a compelling solution to address these integration challenges. This paper presents a novel blockchain-based self-sovereign identity (SSI) management system that promotes global interoperability by generating decentralized, secure, and unique identifiers for edge devices worldwide. The proposed system leverages the power of permissioned Blockchain, specifically Hyperledger Indy, a distributed ledger technology (DLT) designed for creating and managing decentralized identities. The EdDSA-based key management and Plenum Byzantine Fault Tolerant (BFT)-based consensus algorithm introduce novelty and effectiveness in the proposed framework compared to state-of-the-art works on identity management. The performance of Hyperledger Indy Blockchain is tested on Hyperledger Caliper in terms of run time of operations and transaction throughput. We proclaim that our work is one of the earliest studies on Blockchain-based SSI management on Hyperledger Indy.
