I hope there is a third party service and the third party is very helpful to hold the total bounty tokens that have been promised by their project to bounty participants, and there is a team that oversees their project to analyze the whitepaper and the performance of the team project whether it is genuine or a scammer
So the point is that the token that was promised to the bounty participant was not in the project team and in the bounty manager, but in the third party
That means what you mentioned is like escrow to hold the bounty token right when it is distributed to bounty hunters and I don't think there is a third party in the bounty campaign and all that has to be a manager and team agreement on how to give the hunters the best.
