Global markets, mainly in Europe and America, require traceability to control quality and seafood safety. For
shrimp supply chain quality management, such as production and processing, blockchain technology has been used in some countries. At this moment (2020), shrimp produced in Vietnam often do not satisfy the expectations of Western consumers with respect to the desired quality, especially in traceability system for accuracy technology (Khoi, 2020). The scientific challenge with respect to the improvement of the quality traceability of seafood supply chains implies the structural incorporation of the important elements in the process of food production, which are based on current scientific research for quality-orientated product development. This paper investigated the legal issues, and evaluate the costs and benefits to companies and countries that use blockchain technology in shrimp supply chain management.
