Yeah, I'm quite skeptical of it as well. If I'm being really charitable to it, then it's a way to synchronize data between parties without relying on a trusted intermediary. That said, it's unclear what practical value that has outside of purely digital applications like cryptocurrency. When you roll it into things in the real world (e.g., supply chains, health records, etc.) then you necessarily have to trust the data sources and sensors, at which point what good is a blockchain?
