 to coordinate, and I talk about this in the book, one of the ways to look at a blockchain is it's a coordination machine. It's a machine that is credibly neutral, that nobody controls, that you set a set of rules, and you know, and I like to say instead of, so Google's old motto was don't be evil, and so I like to say with blockchains, instead of don't be evil, it's can't be evil. It's just like baked into the code, it can't change.
