There’s this post of mine, also this article gives some background on the application of PIR to anonymous messaging. Basically, I’m trying to do a basic version of that, but using a state-of-the-art PIR protocol introduced in this article. It’s still not great performance-wise, but it’s enough to be practical (as stated, many thousands of users given enough resources).

No, sorry, I haven’t uploaded anything yet, I’ve only coded the protocols and some benchmark code. The idea is for each client to send and receive data continuously. Since text messages are pretty small and YPIR+SP doesn’t have a lot of overhead, that could be a reasonable way to conceal all metadata, as long as there are not enough people connected to overwhelm the server.

Sorry! I meant Private Information Retrieval, that could allow metadata-hiding messaging.

I guess we could make one using newer FHE-RAM techniques and some edge case handling.

Relevant context

Indeed. Do you disagree on what I said?

Israel was basically created by the West, in land that belonged entirely to Palestine. Then, decades later, with Western help, Israel had conquered half of that land, and the UN just decided to enshrine the borders at the time. Now, some more decades later, Israel has expanded way beyond those “compromise” borders, thanks to even more Western help.

There is no “internal conflict” that the West needs to help ending. It was always the West, seeking to create an allied enclave in someone else’s land. Or, to build on your metaphor, this is a fight between the adults and the only child who was there from the start, because they want their own kid to play there instead.
