Project update: PIR-based messaging (lemmygrad.ml)

After some investigation and benchmarking, it looks like the best PIR protocol for this use case is YPIR+SP (from February). On a single compute- and network-constrained server, with users on constrained (and possibly metered) networks, this would amount to providing service to up to 1000 users while keeping latencies reasonable; by (quadratically) scaling the server(s) enough, that could become up to 100,000. That means this method of message routing could definitely work, although I look every day in case new protocols are published.

Do you have a link about your messaging app? And PIR doesn't conceal the existence of traffic, so it doesn't seem like the right thing for messaging. It's more for databases as the name implies. What exactly are you trying to do?
