Hello,
Why would you want to marry a deflationary cryptocurrency with an inflationary fiat currency?
These are antithetical pairings because the cryptocurrency would generally have a fixed money supply whereas fiat generally runs the printing presses to continually circulate and introduce new specie into the supply.
Here's the narrative. Foocoin comes along with a total money supply of 1,000 FOO. The developer decides the value of FOO should be tied to the official currency in Venezuela or Zimbabwe.
Overnight, Venezuela and Zimbabwe devalue their currency by a factor of 100.
Now Foocoin are worth 1/100th of what they had been initially even though they're still worth the same amount of shitfiat from Venezuela and Zimbabwe.
You're essentially asking for dollar proxies, which would be yet another debt receipt.
The purpose of these new digital currencies is to resist the inherent problems of inflation and fractional reserve lending.

In other words, unless you expect the dollar's money supply to be fixed; with all other things being the same, tying a cryptocurrency to the dollar guarantees a loss.
