Does this sound a bit like nubits?
Did you hear the interview with vitalik where he mentioned a two tier coin?
Like a symbiotic secure coin and volatility coin pair, where the volatility coin would provide the needed liquidity to keep the price of the stable coin stable?
Also some stuff about hybrid pos/pow systems, and how the miners really have no power in the system at all. If the wallet holders, the people that run the full nodes and the core wallet software decide to fork, the miners are kinda out of luck... can't even mount an attack at that point if you were to change to something other than sha-256...
Was very interesting to me, and thought it might be interesting to you, as a fellow miner. Hang on one sec I'm get the link
