Dependable Food Traceability Data Through Blockchain and Database Integration

Traditional databases have been important for supply chain businesses, helping them store and manage data for logistic operations. However, growing demands for transparency and traceability, especially in food products, have exposed the risk of data manipulation by dishonest participants in the supply chain. Blockchain technology has the potential to solve these issues by providing a decentralized system to store and share product data, ensuring integrity without any single organization having unchecked control. This work explores the integration of traditional database systems with blockchain technology, focusing on a supply chain scenario, to achieve dependable food traceability data. The integration leverages specific design patterns to efficiently structure and organize system implementation. To evaluate the effectiveness of this integration, a food traceability application was developed based on a real-world use case. The results show that integrating databases with blockchain, using design patterns, can protect data from tampering and make the overall system dependable.
