DORIUM is a socio-economic system where an online-community decides about the financing of sustainable projects and the remuneration of successfully obtained long-term value added in social and economic aspects. Funding is provided through the well-directed emission and coining of a new currency (SoBz) which enables the growth of the socio-economic system from within itself. The additional economic system, the online-community, the new value system and the new socio-economic currency are implemented on the basis of the blockchain technology. The blockchain technology has already demonstrated its usability in many fields and has gained international acceptance.
