Does what happen a lot? People who might not know or trust each other needing to collaborate in updating and maintaining some kind of shared database? Yeah, it happens every day, everywhere, all the time. In fact, it is exactly what you and I are doing right now. In our case, though, we happen to trust Y Combinator to mediate our exchange. If our exchange were hosted on a blockchain, we wouldn't need to rely on Y Combinator to keep track of the upvotes and the downvotes, and to preserve our comments in their original form.
