Not sure if it will not have "go arounds" @kenanqhd . What then holds the "boss" to not create secondary acount "freedom2", move half of his stake to his twin/clone, and elect the first 10 witness with "freedom" and the other 10 with "freedom2" ?
Big potention to reduce the power of boss is in reducing his dominance. By encouraging more orcas and dolphins to make their votes for witnesses. How many of them do now? 7%? 15% ? (I've seen some post on this subj)
Make the participance from all of us in witness vote 5x times higher, and the danger from one single dominating boss goes down 5x times. Or even more.
Beat this.
P.S..
As smth towards such risk reduction I see the "dophin council" initiative by @kabir88. Check his blog.
