I had no idea of your history extending to those formative days! Although not sure I totally understood the fine points about POS, you explained clearly enough the motivations to seek an alternative in the form of the new dPOS that a layman should be able to grasp how it came about. Quite ingenious, actually, though we're still in somewhat "early days" of figuring out how to make the system totally trustless and resistant to different attack vectors.

Like other commenters, I wonder if we can explore in a major way various alternative options for witness voting — 1 SP, X votes (X being 1-30), the ability to vote for as many witnesses as you want, where the % of VESTs is split up between them, etc. What about an exponential curve of witness voting? Perhaps in the context of this series you might be able to enlighten us as to the decision to go with the 30x multiplication if you were around for that?

Anyway, grateful you are finding the time to keep the solid posts up in these hectic circumstances — there is still such widespread ignorance as to the basic functioning of blockchain that it's really important to have concisely-written articles like this available for people who are interested—I guess we are really all still early adopters? It feels weird to say that when we're a decade deep into BTC's life, but in the grand scheme of things that's really not so long. Be well @blocktrades :-)
