Fellow #Bitcoin node runners:

If you are running Bitcoin Core 26.0 please enable this in your bitcoin.conf file:

v2transport=1

This will enable BIP324 v2 transport protocol which as I understand it causes communication to be encrypted between nodes that have v2transport enabled. I can see from my own node that there are very few other nodes have have BIP324 enabled! Lets bring those numbers up! You can check your own node with:

bitcoin-cli getpeerinfo | grep transport_protocol_type

and hopefully you see a few "v2".

I will check and update my Umbrel node runner. Thanks!

No can do, running Bitcoin Core 24.0.1

I currently have 198 peer connections to my #Bitcoin node and have only 1 peer with whom I have a v2 Transport connection. At least I know it works but we have a long way to go!

💜

That's actually not a bad rate if it needs to be manually turned on, especially considering how relatively recently it was released.

YESSSSSSS

Done! 🐶🐾🫂🫡

I should do this. Thanks for the reminder.

I still have yet to upgrade to v26.

Ill stop being lazy, read the change log and update soon though. V2 transport sounds useful.

None of my peers are using it ☹️

I had to have it running for a day or so before I got any v2 connections.

Useful

Have not heard about it. Thanks for the heads up. I will do some research on this and get educated.

any links to further reading on the topic?

It's mention in the release notes under "notable changes":

https://bitcoincore.org/en/releases/26.0/

nostr:npub126ntw5mnermmj0znhjhgdk8lh2af72sm8qfzq48umdlnhaj9kuns3le9ll this would be a great feature to add!

Does this still allow comm between node thats havent activated the « v2 » ?

Yes

Last time I've checked, we had ~500 V2 enabled nodes. If I remember, I'll check again

Doing my part!

nostr:npub1aghreq2dpz3h3799hrawev5gf5zc2kt4ch9ykhp9utt0jd3gdu2qtlmhct will this be easy to change or set by default when we move to Bitcoin Core 26.0?

If you aren't familiar with the inner workings of Umbrel AND the bitcoin.conf file, it doesn't seem very easy/safe. Here are some people discussing making changes to bitcoin.conf on Umbrel:

I just run Arch Linux and run Bitcoin Core as a program on my system.

Thanks very much for looking into this.
