Sunny knows that "good enough" and "dead simple" wins.
Thats probably one of the worst mottoes I've ever. You are right to suggest that we shouldn't over complicate things, but "good enough" never wins.
Also if Sunnys involvement in PeerShares is the clincher, you might want to reevaluate your position. In a recent chat discussion between Sunny King and Bytemaster on peercointalk it seems he was not as involved with peershares as you suggested.
Peercoin is not complete in my view and has some remaining issues, before it can be considered a viable pos-solution, most glaring one being their checkpointing requirement.
I really want to like NXT and even though it is not strictly a technical issue with their particular solution, but I do not like their cloak and dagger behavior with the source-code and only releasing it to peer review after they "feel" the world is ready.
Clout do you think adding cpos to the discussion and/or poll would be advisable or is that proposal still too theoretical?
One little addendum regarding the whitepapers by Daniel Larimer, part of the "security model" in his theories is that of many competing chains and free market choice between them, instead of the other seemingly isolated central blockchain models. While I understand the philosophical ideal of wanting security solely through algorithms, I'm not convinced that this mathematical Elysium is achievable in practice, besides it all hinges on market evaluation by humans anyway. So while not being limited to tapos/dpos I do think the free choice between chains implied in those whitepapers (ByteMaster always mentioned the competing chains when I've heard him explain his concepts) is more versatile than other models.
PS
What's up with all the references to the scores on IQ-tests and drawing conclusions from them? To me those things were more about how long can you fight the boredom and keep focus. Most of the ones I had to fill in even used multiple choice, talk about ridiculous. Multiple choice makes it just about impossible to give the wrong answer.
