Some time ago, Carrefour Italy announced blockchain based tracking of chickens for sale in their supermarkets.
For starters, this will allow to collect, on the blockchain, traceability data on lemons and oranges and make it available to customers, while by the end of the year the service should also be extended to tomatoes, clams and dairy products.
The products traced are equipped with a QR code on the package that, by scanning it, reports all the information traced for that individual product.
The experiment, already underway with poultry, has given encouraging results: doubling revenues on products traced and a significant increase in visits to the webpage accessed through QR codes.
The strategic plan is called Carrefour 2022 and plans to use blockchain to enhance those products that need more guarantees for customers.
In particular, it should serve to certify the origin and processing, especially of products Made in Italy, in order to prevent counterfeiting or misuse of the names and DOP and DOCG certifications around the world.
The system has been developed on the EY Ops Chain food traceability based on Ethereum.
According to Giovanni Panzeri, director of the Carrefour brand product line in Italy,
“it is one of the tools that, at the Group level, we are implementing to achieve the long-term goal of becoming a world leader in food transactions, a necessary change that we carry out with our customers, following the values of quality and reliability of the offer, sustainability, as well as the accessibility of information“.
The project is carried out together with EY Blockchain Hub Mediterranean Leader, of which Giuseppe Perrone is an advisor, he explains that thanks to blockchain technology,
“all complex supply chains will improve the efficiency of quality control, identification of responsibilities, improvement of interactions in pricing dynamics and product positioning“.
In addition, Perrone suggests that this will result in 15% reductions in quality control time, 5% improvement in product profit margins, and a 20% reduction in overall process time.
Riccardo Passerini, EY Consumer Goods Leader, adds:
“The blockchain is now perceived by producers, distributors and the end consumer as an enabling tool for full traceability. The road has been mapped out, as shown by the first applications and the interest expressed by three-quarters of the Italian large-scale retail trade“.
The data recorded in this way are not validated by a trustless system, so the consumer must trust the correctness of Carrefour when accessing it. Transactions can be viewed on Etherscan, the block explorer of Ethereum, spending 0 ETHs for certifications.
However, one can be sure that the data is stored by Carrefour and not others: the blockchain, in fact, does not make true the data stored and exposed to consumers, but it certifies the date of their registration on the blockchain and their actual content.
