Sort:  

Yeah probably not currency as we know it now but certanly a token to trade goods and that is all we need I think.

In the Lorraine (a small part of Bern, Switzerland) they introduced a sort of currency which is all about helping your neighbours. Some electricians, painters and a local food store are participating and they just exchange goods for services via this alternative currency.
Of course it is not a global thing but I feel like it is a nice try to bypass the banks once again.
