Blockchain-Powered Traceability and Security Platform for Agriculture

Ensuring the safety and quality of essential agricultural commodities such as wheat, rice, and maize within government-operated supply chains has become increasingly critical due to persistent issues of contamination and safety breaches. Existing traceability processes covering the journey from government funding through raw material procurement to final consumer delivery remain insecure, costly, and complex, while lacking scalability for large-scale agri-food distribution. Additionally, consumers are often without adequate tools to assess product quality or detect contamination, limiting their ability to determine food safety. Blockchain technology presents a transformative approach to enhancing transparency, security, and traceability in both governmental and non-governmental agricultural supply chains. This study proposes a blockchain-based model employing smart contracts to track and record all transactions and interactions in the government corn supply chain. The system ensures real-time availability of trustworthy product information, promoting informed decision-making across stakeholders. Transaction records are stored on a public, tamper-proof ledger, guaranteeing operational transparency. The proposed BSIGSN framework enables secure, efficient, and immutable monitoring of corn products, supporting improved safety and quality assurance. Performance evaluations demonstrate that the framework achieves notable cost efficiency, scalability, and security, with reduced computational overhead compared to conventional supply chain systems.
