With IT skills, entrepreneurial experience and a good knowledge of public institutions, Xavier has a strong interest in emerging technologies from a technical, business and regulatory point of view. The subject of smart contracts and the digital formalisation of legal relations on the blockchain fascinates him. He is currently working with Isabelle on a plantoid, a sculpture that finances its descent through smart contract. Lavayssière has founded Les Bricodeurs, a group of designers, artists, engineers and technicians to help disseminate digital culture, especially among young people with "Ada Workshops", and is part of the global movement of civic tech developing technical projects. He also co-founded, a few months ago, the School of Design and Digital Crafts to support large groups, artisans and freelancers in their growing competence on digital issues with a pragmatic and multidisciplinary vision based on a network of sites and expertise.
