  This paper is the first attempt to formalize a new field of economics;
studding the Intangibles Goods available on the Internet. We are taking
advantage of the digital world's specific rules, in particular the zero
marginal cost, to propose a theory of trading & sharing unified. A function
based money is created as a world-wide currency; "cup". We argue that our
system discourage speculation activities while it makes easy captured taxes for
governments. The implementation removes the today's paywall on the Internet and
provides a simple-to-use, open-source, free-of-charge, highly-secure,
person-to-person, privacy-respectful, digital payment tool for citizens, using
standard smart-phones with a strong authentication. Next step will be the
propagation of the network application and we expect many shared benefits for
the whole economics development.
