Yeah, I studied blockchains before for a job (some business person saying: "hey we should really look into blockchain, and AI, and Big Data, and IoT, because errr...") and I always felt stupid and like I didn't understand it. Simple things like, why is this such a big deal? What problem does it actually solve? Why is it so amazing compared to a database? It's so, so difficult to actually read what these projects actually "do" sometimes. They often don't define what they think a blockchain actually is, or their threat model, or what their solution concretely does compared to regular databases. Once they got me to look at some project similar to this, and I was so confused as to why anyone would care I literally posted it on Hacker News because maybe they would care? But it got shot down. Which was actually quite a good moment for me because I realized that yes, I am right, this stuff is actually nonsense. I eventually realized that, perhaps, they're just deliberately obtuse. Banks or other business people are obviously falling for it. Wait until these bankers learn what Git is.
