"Fully homomorphic encryption" and "Brainfuck" in one sentence. I guess now I've seen everything :P but nice idea (obviously the language doesn't matter that much if it's a VM). Did some fully homomorphic $stuff for my bsc thesis,... Was this for a thesis as well, or just for fun? I guess next step is to use BF instead of Python? ;)

Just for fun. I am taking it seriously, but I have no other motives other than to learn. This tech has serious potential to fix a lot of privacy problems. I thought it'd be good to have this out there.

As a BFer and a mathematician, I applaud you for this. Quite marvelous, and I wish I'd done it myself.

Could you elaborate on the practical applications? I find this sort of thing very interesting, but it seems to get computationally infeasible once you apply it to any sort of real-world problem.

Well, this project as it currently is makes no sense to use for anything real. What this project is trying to show is that ANY computation is possible with this.

So we don’t necessarily have to create an entire VM to, say, run a FHE machine learning model. That can be built directly and specifically optimized for the task. I think that’s where this is currently useful for real world stuff.

One practical application is DRM

A practical application is that you can host your code on any untrusted server and know that the hoster won't lift your data.
