This paper explores integrating blockchain technology into knowledge management systems for academic credentials to enhance security, efficiency, and trust. Utilising Hyperledger Fabric, the proposed framework incorporates Decentralized Identifiers (DIDs), Verifiable Credentials (VCs), and Self-Sovereign Identity (SSI) principles. The system is designed around five key modules: DID management, schema management, credential definition, claim definition, and role management. Each module plays a critical role in ensuring the integrity and authenticity of academic credentials. The use of smart contracts on Hyperledger Fabric governs the lifecycle of certificates, enabling secure issuance, storage, and verification without relying on intermediaries. This decentralised approach allows universities to issue credentials that students can securely store in their digital wallets, while verifiers can authenticate these credentials by accessing the blockchain. By leveraging these technologies, the proposed system enhances data privacy and security and streamlines the verification process, significantly reducing the time required. Integrating blockchain into academic credential management represents a transformative step towards a more secure and efficient system.
