> ML on a blockchain

I would actually love it if you had a link with more info on that. Don't take this the wrong way, but my first guess would be that that basically isn't true; either it's not actually machine learning (as is understood today) or it isn't actually a blockchain but rather normal distributed computing being "verified" via blockchain somehow?

Would love to be proven wrong though.

There are basically two approaches to on-chain inference: consensus-based approaches (several parties run inference and give a claimed result), and zkML (one party runs inference and proves the result cryptographically).

zkML can be done using general-purpose ZK libraries (since they support arbitrary computations), or there are some specialized tools for proving ML inference, such as https://github.com/ddkang/zkml. It's currently pretty expensive to prove huge models like LLMs, but there's a lot of work being done to make it more practical.

I am still very sceptical about this because it looks very slow, but it seems to work.
