Once upon a time there was a problem. A mathematical problem. A problem that nobody ever solved before: The Byzantine Generals’ Problem. It is about the capacity of systems to continue correctly working if some of the components of the system fail or don’t act as they should when reaching consensus.
So, if a computer system can keep a common consensus without having central points of failure, it means it solved the problem. And that means you could create decentralized databases, decentralized apps and decentralized social networks that are on the same page, for example.
