| Abstract | Coffee is an internationally popular drink with a wide range of flavors and recognizable brands. Traceability information for coffee products is vital as its origin (including varieties) can affect the final taste of products in coffee shops. In addition, differences in the harvesting process, processing of cherry beans and the processing to roasting of green beans can also provide significant flavor changes in the final coffee product. Transparent information is important to prevent the falsification of information and to keep customers loyalty and trustworthiness. In this study, we have investigated the challenges in the coffee supply chain, highlighting the challenges in traceability system, quality assurance, and environment. A blockchain-based system for the coffee supply chain is proposed to explore and demonstrate its potential to address the challenges. To achieve the goals, the proposed system integrates the certification and traceability system together. First, the certification system enables the certifier sector to issue certificates to eligible coffee producers including coffee processors and roasters. Then, the producer can use this certificate in the traceability system as a proof of their standard. Second, in the traceability part, we focus on tracing and tracking the production information between coffee processor and present this information to consumers in traceability reports that can be accessed via QR code. We have verified and validated our proposed system with various cases with successful results. The proposed system can ensure the transaction transparency and security. In addition, consumers are aware of the product provenance along with the environmental practices occurring during the process of making coffee beans. This is a key factor for both roasters and processors to consider and to ensure the environmental-friendly practices. Thus, coffee consumers and coffee producers can help reduce the environmental challenges in the coffee supply chain. |
