IBM posted this short video to demonstrate a simple example of real-world blockchain application.

In this example, blockchain provides a small business faster access to credit.  More specifically, what is demonstrated is how blockchain facilitates a small business purchase of a number of computers from an oversea supplier via a letter-of-credit from a bank.  Blockchain facilitates the transaction by making available pertinent information as a transparent and trusted data chain so that all parties can readily identify details to ship the computers and transact payment.
