Back in the early 00's there were companies "egold" and "goldmoney" that did effectively a centralized, infinitely divisible currency denoted in gold and exchangeable for gold. egold got shut down for facilitating money laundering. I think IIRC goldmoney retired from being a currency and became a non-exchangeable gold vault. Governments really didn't like them.
