You're right, you do mention proof of stake and dismiss it quickly. There is also delegated proof of stake, where validators can elect a leader without needing a proof of work arms race.
But you should really look at Ripple's consensus and study it:
As well as HashGraph. Both of these do NOT require proof of work!
But in any case I think consensus is the wrong long term goal for technology powering currencies and other things. See my other comment in this thread regarding that (https://news.ycombinator.com/item?id=15646385)
