Enhanced Blockchain Interoperability Through Hyperledger Fabric and SHA-256

Abstract

Stakeholders throughout the food supply chain-from farmers to consumers-can gain safe, unchangeable views of the origin, movement, and processing of food through the distributed and immutable ledger of blockchain technology. Traceability and accountability are thereby made possible by this transparency, ensuring food items meet safety and quality guidelines and allowing consumers to make informed decisions. Our proposal for blockchain-based agri-food traceability follows the Bitcoin SHA-256 hash mechanism to provide a safe and impregnable way of monitoring agricultural products across the supply chain. Data is collected, annotated, and given a SHA-256 hash before getting written across decentralized blockchain networks. As the blockchain is fully visible and unchangeable, data integrity is assured so that diverse stakeholders can track the provenance of any product. In addition, the automated and easy use of smart contracts creates further accessibility for participants and clients, thereby ensuring trust and transparency in the agri-food system.
