Blockchain is a digital storage and transmission technology allowing the transit of secure and forgery-proof information, which has been booming in recent years on many projects.
Blockchain is a database containing all exchanges history between users.
Applied to the food sector, the blockchain allows to store tracability information on everyday products.
It allows a follow-up of the entire supply chain (producers, processors and distributors) and to inform the tracability information that concerns them (dates, places, livestock buildings, distribution, processing, etc.).
This device ends with a QR Code attached to item label. It allows consumers to access tracability information via their smartphone, such as location and method of breeding, contact details of the breeder, food (cereals, French soybeans, without GMO, etc.), lack of processing (without antibiotics, etc.), labels (AOC AOP) and the place of slaughter.
