This video was uploaded back in January concerning Landstead which uses NEM blockchain tech to create a decentralized registry of land and other properties, allowing government and citizens to co-create an open blockchain system that can be trusted and consulted by interested parties.
Fast forward to now and the demo has actually been released on their site below:
