A Secure, Scalable, Scholar-Authenticated Digital Hadith Storage Model Using Hyperledger Fabric and IPFS
摘要
The problem with readily available digital Hadiths is their protection. The spread of fabricated Hadiths on the internet leaves the typical Muslim at a disadvantage in differentiating between them and authentic ones. While some websites allow users to verify the authenticity of Hadiths, they rely on a centralized information system, making them vulnerable to data tampering. This paper proposes a model utilizing the Hyperledger Fabric blockchain with the Raft algorithm to provide a secure way to store and retrieve hadith. Moreover, it employs role-based access control mechanisms to prevent unauthorized modifications. The model operates through key steps: (1) registering users, with hadith institutions deciding who is accepted, (2) allowing hadith students to upload new hadiths and request scholars to verify them, (3) allowing hadith scholars to review hadiths, and each hadith requires approval from two scholars from different institutions to prevent centralized control, and (4) storing only the essential hadith data on the blockchain ledger, with the full Sanad and commentary stored on the InterPlanetary File System (IPFS) to improve scalability. Additionally, any scholar on the network can submit a request to update a hadith if an error is found. Users can view both the original and corrected versions of a hadith and the scholars who have approved each version. Experimental results using the Hyperledger Caliper tool indicate the network scales effectively. Implementing this model has implications for the Muslim community, as it enhances the integrity, transparency, traceability, and availability of hadiths while mitigating the risks associated with centralized systems and fabricated hadiths.
