Came across a REALLY cool project in Sardinia this weekend called Sardex. "Sardex is a regional business-to-business (B2B) "commercial credit circuit," or "credit club" - a members-only network that allows local Sardinian small and medium-sized enterprises (SMEs) to do business by extending each other euro-denominated credit rather than paying in cash." Really interesting example of p2p community economies. Apparently they aren't allowed to expand to the rest of Italy because it is a real competitor to the Italian Central Bank 🙊
