Actually, in your example less needs to be done to create an inflation resistant asset than one that tracks inflation.
Assuming static demand for the anti-inflation currency (NuBit-2014): if 1 unit of NuBit-2014 were issued in 2014 with a value of $1, and USD devalues by 50%, 1 year later if demand & supply of NuBit-2014 remained stable, NuBit-2014 would automatically be worth $2, as its value hasn’t changed & the USD has devalued.
However, in this event, for standard NuBit (not anti-inflation) the supply would need to be increased to maintain a stable peg with USD, or its value would rise above $1.
There is no USD reserve in the system. The supply is managed by variable currency issuance, and demand/supply is managed by offering parking rewards. As long as supply / demand is able to be managed correctly, the peg can be maintained without a reserve, though reserves can build confidence in the peg’s viability in the event of a drop in demand.
