Applications for blockchain can be found a lot. For example, I think that people will no longer need notaries. Why do you need notaries if you can use a smart contract? I think that makes perfect sense. There are many specialties that in the near future may disappear and people do not have to spend money on it.
This is a great example and something we are currently working on. The idea is that the constant development in the blockchain community will create new and exciting ways to implement the tech. The same way that the steam engine revolutionized transportation, blockchain will revolution business.
