Medicines, chickens, beer … Crystalchain puts the blockchain in all sorts of ways

Do you know the whole history of your beer up to where the barley that composes it was grown? This is one of the possibilities offered by Crystalchain. Its creator, Sylvain Cariou, was a guest of 20 Mint au Carré. The opportunity to ask him to detail the benefits of blockchain for companies in all sectors.

What is the principle of Crystalchain?

Crystalchain was founded in 2016 and aims to leverage the blockchain for all non-financial applications. With our partners, we realized that there were many things to leverage beyond the financial aspect of the blockchain. The first idea that emerged was that of drug traceability, then we ventured into traceability in general. I had the opportunity to collaborate with lawyers, operators in the shipbuilding, food industry, etc. Crystalchain then began working with the food industry in 2017 with Carrefour and Les Poulets d’Auvergne.

Can you tell us what a tracked beer is?

We work with a large agri-food company that produces barley and then sells it to brewers. The first ever was Eurélienne, a small brewer from Eure et Loire that produces local organic beer. Traced beer therefore means a beer from which we can know all the origins of barley: where it was harvested, stored in which silos, when the malt was produced, when the beer was produced and where. All this in a QR code on the bottle neck. All the consumer has to do is scan this code to see the history of his beer bottle and his entire journey in his hands.

What is the contribution of the blockchain? A simple QR code could bring all this information together without having to go through the blockchain.

The blockchain is an advantage. It is entirely possible to record this information in the traditional way, but the blockchain adds a dose of trust. In fact, every information, every malt production, every delivery of barley is recorded on a private blockchain. People relate to each other.

We retrieve information directly from production information systems, for example in a factory. The actors know each other. We make them sign a charter when they collaborate with us, meaning that they undertake to provide this or that type of information and not to use it otherwise than intended. They also undertake to provide truthful information.

The second level consists in checking the consistency of everything: what enters a factory is the same as what goes out, etc. The supplier will declare a certain quantity sold and the customer will declare a purchased quantity and we check the balances.

You propose to set up a traceability system but also to optimize production thanks to the data you collect …

Exactly, most of the projects we carry out are carried out within a company. This allows him to have an omniscient view of everything that happens on his chain in terms of quality, production conditions, origins, etc.

Regarding the environmental issue, we collect all kinds of data on the sector of factories, producers, breeders, controllers, etc. We verify them, we authorize them in the blockchain, and then we can exploit them to our liking. This means setting alarms in case of quality problems, measuring greenhouse gas emissions, evaluating water consumption on production. Then calculate the distances traveled by the product and raw materials.
