We have not upgraded to latest QUIC version on 3f and I’m not sure we will, I’ll let @shamil to weight in on that. But it should be fully functional on next version of Gemini network and maybe even enabled as the primary protocol.

Well, I tried building it myself with libp2p-quic v0.9.2 and everything is working fine so far, except, of course, there are almost no peers on QUIC.

Also the farmer’s logs are filled with these warnings. Based on what I have researched, they are generally harmless.

It might be necessary to upgrade the rest of the network to newer version as well to avoid these

Is your Quic version compiled after modifying the official code? I also want to give Quic a try.

If you want to use libp2p-quic v0.9.2, just edit the corresponding line with the crate version in the crates/subspace-networking/Cargo.toml file:

[dependencies.libp2p-quic]
+ version = "0.9.2-alpha"
- version = "0.8.0-alpha"
features = ["tokio"]

You don’t need -alpha anymore
