Improved Food Traceability for Restaurant customers using Blockchain Technology

Traceability has become prominent in multi-tiered production systems. It provides assurance to consumers about the transparency and quality of the product. Blockchain food traceability has reasonable attention from the agri-food area. To boost the credibility, efficiency, and safety of the food products, the supply chain should quickly trace the entire lifecycle of food items from their starting point to each phase of the networks. Restaurant customers can trace their food from “farm to fork” with the help of QR codes and smart contracts. This study focuses on restaurant traceability as an example, in which the relationship between supply-chain partners and their networks is shown using a smart contract. The proposed system can build trust among entities that participate in the supply chain network, where distributed ledgers are often used to record and authenticate transactions.
