The FAIRCHAIN Blockchain solution is being evaluated as part of the Greek case study at the Stymphalia dairy premises. It concerns yogurt and feta cheese productions. Measurements are taken and the information is made available using QR codes, printed for piloting purposes on the new packaging of the products. Piloting users (and a few consumers) are led after scanning the QR to our FAIRCHAIN trustworthy, Blockchain-based traceability solution. The case study plans to contact one more retail (supermarket) to present our work and the Greek competent authority for food safety.
