I can think of small problems that use blockchain as a solution, but they're relatively niche and only make the game-space straddle the real world, so they tend to be a bit on the vaporware side. Handy, sure, but I'm not sure they are A) 100% necessarily or B) as revolutionary as everyone seems to think blockchain is meant to be =[ EDIT: forgot to say, this could be a complete lack of imagination on my part past what's been done with blockchain already or just my horrible indoctrination into the game-space like some kind of cult =)
