I've heard economists propose that blockchain technology could be a solution to corruption, particularly for land registries in underdeveloped countries. Because of the dispersed nature of blockchain, it would be very hard for a corrupt government official, for example, to switch a land title to a friend, family, or himself, and therefore future property registries could go on the blockchain. I think Georgia has done that.
