I think you are somehow correct here, sometimes people can misbehave a lot in their best interest in getting extra funds from people they are trying to help or working with. There are some locals especially the chairmen in many of these local areas that will want to compromise the process just to make more money from the team. That means LandDAO must make sure that they are dealing with the right set of people in these local regions so the process of acquiring these lands in large quantities will not be jeopardized.
I believe the village heads will always nominate their best and most trusted people to run the affairs of LandDAO in the community but in a situation where their representative is trying to misappropriate funds or playing smart with their position to affect the performance of the company in respect to the purchase of lands and the works that are been carried out in the community, the monitoring team of the company can swing into action to ensure they don't let the community bad eggs affect the good projects they are carrying out in the community.
Also I think the community representatives will not be allowed to make certain decisions without getting the approval from the office or their boss@ LandDAO so when there are issues relating to funds and jobs, the monitoring team should be able to notice that quickly.
