Well is really a good strategy that lanDAO is using by employing indigine of the host communities were they procure their lands as this will give investors the confidence to procure lands from lanDAO, the fear of whether a particular land is in dispute or not will be over come .
The issue of technological means of identifying land that is in dispute, I wanted to dispute that fact but since you gave reason for not disclosing it here I will let go of it, however I believe LandDAO should relate such means if there is any to potential investors that will be acquiring or wants to acquire land from them as this will make them to pull others investors into landDAO.
If the team has an unclosed means of identifying if a land is in a dispute or not then I think that's a good move to prevent or reduce the attempt of land grabbing which is a frequent occurrence in most regions in Asia and African. Also when it comes to development of the local regions where these lands will be purchased, the locals are the ones that will benefit more, making the regions more residential to new expatriates that will be relocating there or having properties there.
Since the team is working on how to make this project a successful one compared to other real world asset in the crypto space, this alone with attract more investors to join the community. The most interesting thing is for LandDAO to make their investors happy.
