@Blazing Black Dragon GDP(Guild Donation Points) are used for stuff like buying monster parts and other items(I think a Rathalos plate costed 500?) and upgrading NPC hunters. You earned them by hunting with a personal NPC hunter(Partner), or with someone clone NPC of them self(Rasta). I think like 1 point per in quest minute or 2 per minute not sure if it changed.
