On the Use of Blockchain Technology in Enhancing Quality Traceability across the Food Supply Chain

This article aims to clarify the cost changes associated with implementing blockchain technology for food supply chain quality traceability and encourage active participation from all parties involved. To achieve this, the article introduces the cost change coefficient and food quality to construct a decision-making model. The model explores the conditions for applying blockchain technology for quality traceability in the food supply chain and the cost-sharing threshold for reducing costs and increasing profits for all parties. The study reveals that the economic value of applying blockchain technology depends on several factors, such as the cost investment of each entity, the cost-sharing coefficient of blockchain technology and the investment cost. Only when the cost-sharing coefficient of blockchain technology reaches a critical condition can it increase the profits of manufacturers and suppliers while attracting their active participation in blockchain quality traceability.
