First Blockchain App For the Masses?

Looks like the first mass adoption of blockchain technology here might be this Know Your Customer prototype created by OCBC, HSBC and MUFG.
Due to Anti-Money Laundering and Counter Terrorism Financing measures taken here, Know Your Customer procedures are very important but are often time consuming and tedious for the customers. If blockchain can be used to ease this pain for all of us, I can see widespread adoption of this happening soon.
This will in turn spur many to think of how else blockchain technology can help in the marketplace.
