This is why validators participation in the voting process is highly encouraged. With or without secret ballot 3 people can still make a decision and all the group will have to stick to it. If validators don’t want to be unrepresented they should simply participate in the ballots. I believe having the secret ballot will help with political privacy of validators, decrease personal risks and increase overall network security. I believe not participating in governance where validators votings records are publicly available helps to reduce personal risks for individual validators and, therefore, discourages them to participate. I believe having the secret ballot will actually encourage validators to participate in POA governance model.
Ballots are not for general public to create or to vote on. I don’t see what checks and balances POA community has in our current governance model. POA community is highly encouraged to share their point of view that might resonate with validators which they can later propose.
I agree that validators have an incentive to vote in the best interests of the validators and POA Network rather than the public. What exactly you don’t like about it? This is what validators are being rewarded for. Are you being rewarded by some public and, therefore, feel obligated to act in their interest?
