Really deep grok article, dear Kev. I'd refer again to this ancient (2015) article applying real understanding of economy and going over DPOS, too: http://www.truthcoin.info/blog/pow-cheapest/ - this can give some solid base for consideration of better results. Also, on Kantianism vs Utilitarianism ... I prefer not -isms ( ethical ideology ) but directly on the iron implementation of ethi-CS .
