I don't know, looking into the papers that are written in crypto research, especially in academia, it seems like there is a lot of very technically interesting stuff going on, especially with zero knowledge proofs for example...

These are largely (if not completely) applications of existing zero-knowledge algorithms to blockchain data, not the application of blockchains to solve some difficult ZK problems or make a useful-outside-of-blockchain novel ZK construction.

And? Applications of research brings new insights into that thing.

So then the innovation of cryptocurrency was an economic one.

It does have the word "currency" in it, so that should not be surprising.

I'll leave the question of whether it's economically interesting to economists and sociologists (though I suspect the answer is it's not at least in this regard, as the pressure to use the same non-blockchain currency seems not too different across the sweep of history). The claim was:

It's not that.

Are you saying it's easy? The PoS algorithms I've read seem quite complicated, and honestly quite interesting. Also there is a lot of academic research about this stuff, some of it private, some of it public.

I mean, I know there are people out there who think that, for example, particle physics is totally uninteresting, and you are of course free to decide that a given research area is totally uninteresting, but you can't expect others to agree. It is just your opinion
