This is where it's going.

If you have to have a Proof of Stake measured as a Proof of Service, why not require the same to mine at all? Just like the MNs are now, instead of hashrate being the decider, size or Proof of Service could be? Or both? Have to knock the idea around. Reducing wasted energy and the silly of ASICs may be a feasible and non-detrimental goal if seen through that lens, but a means for doing it would have to be conceived, and that does not yet exist. I'm sure Evan has already thought of it and just hasn't said anything cuz he's busy.
