Updates | 22-05-09
Hey there, Lightning friends!
What a lot of updates again this week! That’s only a good sign! We want to emphasize the disk space solution Kloek mentioned! Oh and read the LN gossip rate-limiting update! The mini sketch method which Alex Mysers researched is a very smart solution to reduce the bandwidth used by nodes.
Don’t let us hold you up any longer! Enjoy!
SUDO APT | UPDATES UPGRADES
- MyCitadel Wallet v1.0
Initial release of this wallet. Support for:
– Hardware signing devices
– Single-sig wallets and multisig with complex timlock conditions
– Taproot support
– Also possible: airgaped and watch-only!

- LN anchor outputs security issue
Bastien Teinturier posted to the Lightning-Dev mailing list the announcement of a security issue that affects older versions of Core Lightning (with experimental features enabled) and LND. He strongly encourages you to upgrade!

- LN gossip rate limiting
Alex Mysers posted to the Lightning-Dev mailing list about his research to reduce the amount of bandwidth used by nodes for learning about updates to the LN channel graph. His method assumes all peers have almost all of the same information about almost all of the same public channels.
A quote from Alex: “This builds on some earlier work from Rusty using the minisketch library. The idea is that each node will build a sketch representing its own gossip set. Alice’s node will encode and transmit this sketch to Bob’s node, where it will be merged with his own sketch, and the differences produced.
One peer can then generate a minisketch from its complete graph of the public network and send that to all of its peers, who can use the minisketch to find any updates to the network since its last reconciliation.”

- LND
Kloek (EP01) shared this recently closed Github issue to help disk space reduction and the crazy DB file growth!
https://github.com/lightningnetwork/lnd/issues/6317
- LDK #1425, #6064 and #6361
– Adds support for wumbo channels (which are large channels with more than 0.1677 BTC)
– Adds new bitcoind.config and bitcoind.rpccookie configuration options to override the default auto-detection logic
– Updates the signrpc method to be able to create signatures using the MuSig2 algorithm

https://github.com/lightningnetwork/lnd/issues/6064
https://github.com/lightningnetwork/lnd/issues/6361 - BOLTs #981
Gossip query compression was removed from the specification. The ability to compress queries and results about the LN network graph wasn’t being used and removing it reduces complexity and bandwidth usage.
