Same with byteball, only replacement mechanism is different.
This is a interesting bit, btw. I don't get how 6 witnesses could be replaced if discrepancy in 1 witness is the max of what is allowed.
Yeah you are getting closer to understanding why Byteball's witness replacement mechanism, is in practice not going to work. But it requires deeper analysis to see that without whales, the mechanism won't be able to not diverge from choosing a new witness replacement.
Bitshares learned by fire that the natural order is divergence in the absence of whales, because of the power vacuum of egalitarianism. That is ostensibly why they launched Steem with a stealth mine so the principals control ~80% of the tokens.
