"This existence of a record that everyone can agree on, and that can’t be altered or cheated is very useful to humans. Humans disagree about many things, and many try to cheat others. But I cannot tell a lie or have a different record for different people. Imagine everyone completely agreeing on something. I am that. And that’s apparently very useful to many people."
