In this paper, we study the impact of blockchain technology on food traceability and consumer behavior based on the case of the implementing company. Blockchain technology has great potential for many applications, and is currently being tried in various industries. In the near future, it may make major changes in social infrastructure and systems. However, there are few examples of effective cases that are necessary for companies to introduce them from the perspective of economics and management. Therefore, in this paper, we focus on the traceability function of blockchain technology and examine the effects and influence of introducing it to a company from the viewpoints of producers and consumers.
