This isn't uncommon. There's hundreds or thousands of companies that combine [blockchain x thing], in some vague hope of getting people in the [thing] industry will give them money. There's never a technical reason for this to happen, other than someone thought it was an attractive sounding idea. Generally speaking there's very few things which could be conceivably solved by a block chain, it's not a solution which can be pasted over any interesting sounding problem, and manages to create a multitude of problems when it is.
