Evaluating Blockchain Adoption for Greek PDO Feta Cheese Integrity

Absrtract: Feta cheese, a distinct and culturally significant dairy product from Greece, has gained global recognition for its unique characteristics and nutritional value. Since 2002, it has been designated as a Protected Designation of Origin (PDO) product by the European Union, requiring it to meet specific criteria regarding its name, origin, production methods, geographical region, inspection requirements, and labeling specifications. However, the industry faces challenges such as food fraud and authenticity issues. Blockchain Technology (BT), with its distributed and immutable record-keeping system, presents a promising solution for enhancing traceability and maintaining the integrity of PDO Feta cheese and other highvalue food products. This study aims to investigate the complexities of the PDO Feta cheese SC, focusing on identifying vulnerabilities with a view to improving the product's authenticity. Using rigorous methodologies, including the Delphi Technique, the study examines the operations and vulnerabilities within this supply chain.
