Abstract
Recent progress in IoT and software development has simplified data acquisition and immutability of information in the agri-food supply chain. In the last few years, several frameworks and applications were proposed to ensure traceability in the agri-food-sector using distributed ledger technologies (DLT) such as Blockchain technologies. Still, no other study has presented a Blockchain-based traceability platform with a lower impact on the environment and lower cost for each transaction sent by the supply chain. This article presents a traceability platform based on Green Blockchain with low energy consumption and costs savings applied to the Fontina PDO cheese supply chain, part of the project “Typicalp”, funded by the European Union (EU). The proposed traceability system is based on Algorand Blockchain, which uses the Pure Proof-of-Stake mechanism of consensus that requires minimal computational power, is highly scalable and environmentally sustainable. In addition to the environmental and financial benefits, the developed traceability platform has made it possible to digitize the entire production chain, making the data immutable and available in real-time for Fontina consortium operators and final consumers.

Summary
Academic Editors: Caterina Tricase, The dairy supply chain is among the most complex of the food supply chain, as it comprises a multiplicity of actors and transformation processes. It is the second most relevant agricultural sector in the EU [1], accounting for over 12% of total agricultural production. Stands out in the dairy sector with more than 50 PDO (Protected Designation of Origin) cheeses, UHT milk, 12% for yogurt, and 7% for fresh milk, 3% for butter, and 2% for cream (2018). Traceability is fundamental for managing recalls in supply chains and minimizing risks [3]
