We believe blockchains will change the world. BlockchainS not the blockchain. If only everyone, anywhere on the planet can have an access to it as well as an equal access, excluding any submission to any form of monopol. We think that blockchains, their development and their regulation, have to be considered at a worldwide level. We believe that we need the flowering of free and multiple uses of blockchains, anywhere in the world, for anyone. So we want to: - Establish a permanent constructive dialog by regrouping, without discrimination, actors of blockchains and anyone interested into; - Educate by spreading relevant information so anyone can understand the impacts and use of Blockchains – notably in developing countries; - Favor by all means development and use of blockchains by regrouping experts and connecting them to anyone could need their expertise for their own projects; - Promote and protect by liaising with public authorities, international organisations and others to educate politics and avoid unnecessary restrictive regulations; - Promote interoperability and accessibility of blockchains, by adopting standard, protocols and open infrastructures; - Evaluate regularly social, economical, political and legal impacts of Blockchains; - Remain independent. We are an international, federal and apolitical association, willing to become an observatory of ideas combined with practical actions. Members regroup by territories and by activities chapters.
