' Complementary currencies ' are often designed to promote financial stability , and for communities that do not have access to financial services ; the alternative currency of the WIR Bank in Switzerland and the Brixton Pound are examples of these creations . Systems developed on the blockchain are a better alternative to ineffective methods that are employed today. However , the exchange between national currency and alternate currency has until now been tedious . By using the blockchain , complementary currencies can be exchanged in a secure manner . This may lead to more and more localised digital currencies being set up in the coming years .
