4. It has a novel block chain debasement (emission) schedule based on an algorithm that relates to difficulty change. I need to study this before commenting.
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 created below:
