I don't like variable block reward based on hashrate/difficulty. We've already seen it in Darkcoin and others before it. It mostly serves as a pyramid scheme attribute. If I did debasement in PoW, I would use flat 1% most likely, 2% max. I'm not a believer in PoW anymore at all though besides it's vital need in distribution. It's a complete dead end. Summary of issues = the cartoon...
I disagree on "dead end" for all PoW. There are potential solutions. None of which will be mentioned at this time.
Remember I pointed out upthread that P2pool is not a solution even if you could force its use, because it is vulnerable to share withholding attack because there is no server in control.
I agree that if debasement slows too rapidly there is a
theory that it will
killdiminish the network effects for the reasons I stated upthread.

halving is tied to time, not to difficulty.
