I've heard people talk about doing on chain analysis from their own nodes.
I assume they wrote the code to do that themselves. It would be awesome to have an umbrel app that does that.

I think most of what they're doing would require to much computing power and storage. To do what they do, the first step would be to pull data from the Blockchain and create new databases from it, with lots of new metadata. Then they run all kinds of statistical analysis on it, regularly refining and re-running it.
Now you could pay a chain analysis company for their results and then load that onto an umbrel with a UI for navigating it.
