Blockchain-Driven Halal Supply Chains: Enhancing Transparency and Efficiency While Ensuring Shariah Adherence

Halal-certified products are in high demand globally, but traditional supply chains face challenges like inefficiency, lack of transparency, and low trust among stakeholders. This study proposes a Shariah-compliant blockchain-based Halal supply chain management system to address these issues. By using Hyperledger Fabric, the system ensures traceability and trust through data-smart auditing, creating a decentralized, immutable ledger with a permission blockchain. The system automates compliance checks via smart contracts and integrates with Shariah boards for certification validation. It also incorporates QR code-based product authentication and off-chain storage for scalability. Periodic audits maintain system integrity, and end-to-end monitoring provides full visibility, ensuring Shariah compliance at every stage. This solution offers a modular, scalable, and transparent approach to Halal supply chains, improving efficiency, privacy, and trust while addressing the shortcomings of traditional methods.
