I absolutely do respond to alternatives to proof of work in my post, thank you very much! And I agree that they may be valuable, but I'm skeptical, and you can reread my post to see why. And, by the by, the DDOS argument is a strawman, because we already survive DDOSes in services every day.

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: https://ripple.com/build/xrp-ledger-consensus-process/ https://ripple.com/build/xrp-ledger-consensus-process/ 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 https://news.ycombinator.com/item?id=15646385)
