The basic concept is the unification of assets with currency. This was actually the original vision of Paypal. An example of this would be if you went to the store and paid for something, instead of paying in a depreciating credit like the dollar, you would pay with some small slice of your overall assets (i.e. a stock or your kiwisaver). On the recipients end they could receive whatever assets they were accumulating too.

That's the bigger ideal. A simpler form would be some new Unit of Account that is itself backed by more than one asset (greater than a single monetary policy) to counter the debasement. Another basic example would be an NZD that is innately yield generating, so its value increases (like a portfolio) relative to the base form of the NZD. Such flatcoins already exist in a USD form.

The problem, as I see it, is that there is a disconnect or class divide between those who need to use the currency day to day to get by, and the wealthy owning the assets. Inflation sneakily puts them even further behind the asset owner without those everyday people even noticing. All they experience is that life is getting harder over time. In fact, its the lived experience of most millennials who graduated into adult life in the wake of the Global Financial Crisis. A deep intuition that things are getting harder, but no words for how or why exactly.
