Hi, Somebody asked me recently and I "got stuck" trying to explain this. When people ask how many ZK nodes they should have a common answer is "odd number: 3 or 5 or ...", so ZK can do majority voting. Correct so far? Another reason is for HA - if one ZK node dies, there are still 2 of them left. And this is where I am missing something core - with just 2 nodes left, how can ZK do majority voting now?
