...I also went through the LanDao site and it seems the land sell procedures on the LanDao would only favour someone with government registered lands...
LandDAO is only interested in government-approved land; at least acquiring land must meet government requirements, it means every deal of land is between the government, LandDAO, and their client. If the government is involved, then I must say it is an advantage for both LandDAO and their clients, which means every deal won't end in dispute.
