One of the greatest outcomes of Bitcoin is the creation of Blockchain technology. As simply as possible, Blockchain technology records the exact history of a transaction including every modification and transfer; allowing information (especially financial transactions) to be shared.
For example, the moment you post a picture online, anybody—theoretically—can copy the picture and say it’s their picture. They can manipulate the metadata tags and even extract private information from the picture, i.e. geo tags etc.
With Blockchain technology, the information is stored and is unalterable. Blockchain technology can potentially allow financial transactions to be safer and even intellectual property to be shared, i.e. music, movies, etc.
