Blockchain offers something solid in the world where everything shifts and changes. Considering this one and many other qualities it has, there are many ways how Blockchain could help us change the world. Below I’ve listed a couple of ways Blockchain could change the world.

* Poverty reduction

Currently, there are more than 2.5 billion people who lack govenment provided identity. Without proper documents (and identity), people cannot sign job contracts, get loans or develop credit history.

Blockchain would allow this huge number of people to participate in the global economy and get an identity which would enable them to get access to financial services.

Also, people working abroad could send the money home with purely simbolic fees, helping their familiy to get more money.

* Better institutions

By putting the data on Blockchain, institutions could become more efficient, lower the costs and reduce the number of errors they make. Also, all promises given before the election by the politicians could be recorded and the people would be able to track whether they held the promises or not.
* Elimination of world hunger

Blockchain-based systems could be a great solution for tracking the distribution of agricultural resources. By reducing the waste in food supply chain, Blockchain could bring many benefits to governments, food growers and farmers. Effective use of food could end world hunger within a couple of years.
* Better law enforcement

Blockchain could help us save billions by making trials faster and easier. For example, the ownership of the land could be put on unhackable Blockchain and when certain criteria is met (the person dies or moves to Florida), the ownership is automatically passed to the individuals specified in the will.

Or in the art, which is a market that isn't regulated properly. There are many people who steal the pieces or cheat in some way to earn money. By placing the data on Blockchain, authors could be sure that their art is almost useless for the crooks, as it would require its approval for any action and receive royalties for every third-party use.

* Better healthcare

Placing sensitive health data onto a Blockchain could prevent errors and ensure that nobody has tempered with it. The technology would also allow doctors to react properly in any situation, as they would be able to access complete medical history of a patient and take care of him in the best way possible.

Hope this answer helps. The possibilities are endless with Blockchain, remember that!
