:-) Thank you for your answer.
In my case I'm not in the "witness business" for the rewards but in order to learn and reuse the chainbase / steem code for other blockchain projects. Therefore in my case it matters A LOT ! :-) That is precisely why I started a witness, to understand how it works !
When you write "look at their signing keys", where do you see those ? I didn't manage to see what you are looking at exactly.
Steemd, steemworld
Signing keys that are stm1111111111111
They arent active witnesses
Oh, indeed, cool, thanks, got it !
Fair enough, I'm not in it for the reward either, I just like being apart of it. Gives me something to do :p
But any way, I hope someone can answer. Because I certainly have no idea :)
