Today there are ways to make computers work together so that they make a sort of money. Sometimes we need to change the way in which they work so that the money can become better, or to fix problems that we didn't think about before. But today, there is no good way to change how they work because everyone needs to agree to change at the same time. We have built a new way for computers to work together so that not only can they agree on who owns what, but also they can agree on how they should change the way in which they work together over time. This can even happen without the need for humans to do anything but say what they would rather have.
