«…l’avènement de l’homme marque un palier entièrement original, d’une importance égale à ce que fut l’apparition de la vie, et que l’on peut définir comme l’établissement sur la planète, d’une sphère pensante, surimposée à la biosphère, la noosphère. En elle, l’immense effort de cérébralisation qui commença sur la terre juvénile va s’achever, en direction de l’organisation collective ou socialisation… » Pierre TEILHARD de CHARDIN

"... The advent of man is marking an entirely original level, equally important such as the emergence of life, and that can be defined as the establishment on the planet, in a thinking sphere, superimposed on the biosphere, the Noosphere. In it, the immense effort which began with the cerebralization of the juvenile earth will end in a direction of collective socialization or organization... " Pierre Teilhard de Chardin.

La sérendipité est le fait de réaliser une découverte scientifique ou une invention technique de façon inattendue à la suite d'un concours de circonstances fortuit et très souvent dans le cadre d'une recherche concernant un autre sujet. La sérendipité est le fait de « trouver autre chose que ce que l'on cherchait », tout en s'attendant à découvrir quelque chose par la simple action de chercher.

"La société mondiale actuelle est en train d’être «unifiée» principalement par la mondialisation des capitaux, des marchés financiers, des transports, des communications, des entreprises, de la consommation. Dans le cadre du marché mondial intégré en émergence, rien n’est garanti, assuré. Tout est à conquérir. L’intérêt de celui qui gagne devient l’intérêt général. On a vidé nos sociétés de ce qui les fait vivre : le bien commun." Un Bien à (re)construire. Riccardo Petrella.

"The current global society is being "unified" primarily by the globalization of capital, financial markets, transportation, communications, business, consumption. As part of the emerging integrated global market, nothing is guaranteed, provided. Everything is about to win. The interest of whoever wins becomes the general interest of our societies. Societies emptied by which they live : the Commons." Although a common to (re)build. Riccardo Petrella.

Le projet coopératif de Welcy permet aux acteurs économiques et sociaux de (re)construire du bien commun. Welcy met en partage les usages de protocoles ouverts entre des organisations humaines, pour l'échange de services indispensables à l'épanouissement de leurs activités. Welcy est un réseau de consensus distribué, utilisant des outils pair-à-pair décentralisés -sécurisés physiquement, légalement et virtuellement- sans autorité de contrôle ni intermédiaire -ni matériel ni logiciel- pour réaliser les transactions et les communications entre ceux qui y participent.

The Welcy cooperative approach provides economic and social actors to (re)build the Commons. Welcy promote uses of shared open protocols between human organizations for the exchange of services, essential for the development of their activities. Welcy is a distributed consensus network, using decentralized peer-to-peer tools without control or through authority to make transactions and communications between those involved.


Welcy is a collaborative and evolutive multimedia project promoting free tools. It aims at using key ideas and practices of the commons movement, including through the creative process of the project itself.
