Bitcoin was created as an answer to the financial crisis, where fraud and other unethical actions caused the world economy to collapse. It shifts from a “trust or doesn’t trust” view of the world to a trustless system. This subtle difference is lost to most. A trustless system is one in which you equally trust and mistrust every person within the network. More important, the blockchain provides a framework that allows transactions to occur without trust.

These same types of frameworks can be used for more than just exchanging value over the network. Here’s an example to help illustrate their potential.

Your license has a lot of information on it that the bouncer doesn’t need, nor should he have access to (like your address). All he needs from the ID is that you’re over the age of 21. He doesn’t even need to know how old you are, just that you meet the regulation requirements.
