Blockchain, briefly

Blockchain is a technology that enables trusted information, transparent, secured, and operating without a central organ.

By extension, a blockchain is a ledger that contains all the historic of exchanges between its users since its creation. This ledger is secure and distributed: it is shared by its various users, without intermediaries, and simply allows everyone to check the validity of the information.

The team
Claire Guillet - F2Fmarket

I’ve always looked for the best products for my family. For me, food means fun and life. I am absolutely outraged by the way we treat and process food today. Beyond marketing and taste, food is vital and we rarely know its origin! Behind a product, there are always lives, stories, and passionate producers who do amazing work.

That’s why I started Karyon. I want to take up the challenge of tomorrow’s foodchain by proposing a healthy and viable alternative for everyone.

Tom De Block - F2Fmarket

As a father of 3 kids, I am really concerned about their future. Looking at the environment we live in, I know we cannot rely on the current managers around us. In the same way, our retail and Food providers are driven by financial benefits, probably at cost of public health. As for myself, If the info would be available, I would only buy from certified healthy foodchains. And with me probably thousands of other worried parents.

So, I see a real need for this Karyon. And with the Blockchain and IoT solutions in my professional catalogue, I feel alike a mission to bring it to the crowd, among other world improving solutions.

Fresh out of my studies, I wanted to put my engineering skills at the service of building tools and reflections that will be used to understand today’s food systems in a systemic way, in order to better build tomorrow’s food systems.
Transparency is for me a fundamental value that must be widely applied to re-establish trust and knowledge at all levels.

By joining Karyon, I want to actively implement digital, operational and strategically sustainable long-term solutions to seriously answer the challenges of our societies.
