Blockchain Based Food Origin Traceability

Abstract

Ensuring the authenticity and safety of food products has become a major global concern due to increasing cases of food fraud, mislabelling, and contamination. Traditional traceability systems are often centralized, lack transparency, and are vulnerable to data tampering, making it difficult to accurately track product origin and movement. To address these issues, this project proposes a blockchain-based food origin traceability system that uses smart contracts and a distributed ledger to securely record product information at every stage of the supply chain. Stakeholders record key data such as origin, processing, and transportation details, ensuring transparency, immutability, and reliable verification. The system also incorporates allergen traceability and quality verification mechanisms to enhance product safety. By improving transparency, reducing fraud, enabling faster recalls, and supporting regulatory compliance, the system provides a scalable solution for food safety and traceability while promoting better coordination, reducing dependency on intermediaries, and supporting informed decision-making across the supply chain.
