A referendum in Switzerland on Sovereign money is expected to be held next year and the Vollgeld Intiative has a great website packed with information.
As banks leave Catalonia following their independence vote, the Catalans can ask the Swiss to help with the technical details of introducing introduce Sovereign money and setting up its own public central bank.

An interesting table shows the Big Banks in Switzerland create almost half the total money in circulation as loans with interest while having the lowest reserves.
The local, community owned banks, the Raiffeisenbanks, by contrast, create about a quarter of the money in circulation as loans but that is the equivalent to their reserves in the form of saving deposits.
