I've written earlier this week about the potential of govts establishing a central repository of citizen identification as a potential use for blockchain technology - in theory this could make economic and employment transactions among people and businesses much easier, which is one of the purposes govt is supposed to serve. 

The German government has announced its new strategy on exploring the citizen services blockchain could support, and citizen identification is at the top of the list. See this article for a little more explanation as well as the other problems in citizen services the German government believes blockchain might be able to help.
