The government of the State of Telangana in India has started using blockchain technology to track delivery of food rations to citizens. This appears to be an ideal use case for the technology. It allows tracking of each ration bag, and who had it when, to signficantly reduce fraud and make sure the rations get to the citizens who need it. 

This can make government more effective and more efficient at the same time - exactly what we're seeking to do everywhere. What other use cases are you seeing or are you interested in?
