Hello, I'm running a dedicated, FIBRE-patched Bitcoin Core local node on a high-performance Ubuntu setup with a dedicated DDNS endpoint and a properly port-forwarded UDP gateway. I’m looking to optimize my block propagation latency. I have a fiber internet connection 0.6 Gig download speed, 0.2 Gig upload speed, below 24 ms latency, about 4 jitter.
I would like to find information on a group where I can find like minded peers to exchange keys for trusted UDP connections.
Below is my GitHub link showing some of my node tooling, and I'm happy to provide traceroutes to your target IP to verify our routing path before we exchange keys.

Thank you,

Have you tried reaching out to miners? If anyone has a low latency connection, it's them.

Thank you for your reply. Do you have any recommendations as for what platform do I find miners?

The fork stopped tracking Core a long time ago, so finding active peers willing to swap UDP keys is rough. Most people chasing propagation latency these days just lean on compact blocks with a few solid -addnode peers.

Out of curiosity, what kind of gains are you actually measuring over plain compact block relay?

lclhost.org posted this article February this year: https://lclhost.org/blog/fibre-resurrected/

The Github repository has been recently updated also: https://github.com/bitcoinfibre/bitcoinfibre/

I was generally interested to see the performance difference (on the latency side) between Core and Knots, performed the test and thought they will be head to head, but the nearly 1 second difference is interesting, so I thought I would try to kick in the FIBRE's UDP engine and redo the test to see the result. So, that is why I would like to get hooked on, on that network, but it requires the secured key sets. I have contacted lclhost.org, but no answer. It looks like they are looking for big guys who have servers in data centers right at the sea ports and not interested in the little guys. I would love to exchange keys with a couple of peers....
