**Abstract**

Modern food supply chain involves numerous stakeholders that are geographically dispersed. This scattered and complex structure impedes the free flow of information throughout the supply chain. Low transparency lays the groundwork for food fraud and delays the implementation of necessary countermeasures when a food contamination incident occurs. Moreover, customers nowadays are increasing demanding in terms of product provenance and sustainability. Under this circumstance, it is urgent to identify effective solutions that can mitigate the concerns of food safety, quality, and fraud. Blockchain has been identified as a promising technology for enabling end-to-end supply chain traceability. This study investigates the main challenges of agri-food supply chain and how blockchain attributes can address these challenges. We also propose an integrative framework of key factors that influence blockchain adoption in the food industry.
