2 weeks ago channel jamming:
- new attack variant discovered by morehouse
- working on updating to account for it
taproot chans:
- got some review from fabrice, roasbeef working on the changes
- still not updated to use the mini script compatible scripts, will do that in the non-staging bit
- rbf co-op:
- lnd still needing to make change for locktime instead of sequence
taproot gossip:
- close to revival...
- near term goal to remove from draft state
- lnd continuing to work on the new code path
bolt12 contacts:
- delving post up, not much progress after the initial discussion
splicing:
- CLN working thru set of changes to
async payments + trampoline:
- rn trampoline node gets a blinded paths, and relays to blinded paths
- the issue is that you aren't forced to use it in a privacy safe way
- so then can use zero hop blinded paths w/ the node themselves
- so receivers can make bad blinded paths, revealing more information to the sender's first hop
- potential work around:
- add another trampoline hop
- essentially requires including the blinded path twice
- may only be an issue if you do trampoline "all the way"
- so instead can do trampoline blinded hops?
dyn commits:
- pushed to slim down version, removing some of the funding output conversion
- few segments that say note for reviewers, guide for reviewers, marking unstable parts
- while we're here....default anchors?
- eclair stopped accepting non static key anchors
- two changes:
- channel type negotiation by default
- reject all non-anchor channels
- most nodes do support anchors these days
TRUC + v3 + 1p1c:
- what can we do w/ bitcoind 28 released?
- how does it affect the commitment format, etc?
- good topic for summit
peer storage back up:
- target for lnd 0.19
- interop:
- does CLN have a full up to date impl?
inbound fees:
- lnd deployed bLIP that was proposed
- discount only for now, RPC will reject anything that's positive
peer alternate connect:
- ability to privately connect out between peers
- diff from
chan_ann: sent directly to a peer, not broadcasted to the broader network - bridge to also allow diff pubkeys to be used for connection subsets:
- brontide handshake mixes in the pubkey
- so if you send another pubkey over an existing authenticated
nLightning:
- finished BOLT 11!
- had some issues re signature computation
- defaults to using the low r (not s?)
- for LN it doesn't care if it's low or high r
- having a hard time signing w/ low r
- signature didn't match
- realized that even post segwit, we use high r on the signature
- related to: https://github.com/bitcoin/bitcoin/pull/13666
- signature was wrong when using this
- should add more test vectors that do include low r

Recently Updated Proposals / Seeking Review
This section contains changes that have been opened or updated recently and need feedback from the meeting participants.
channel_reestablishrequirements #1049 or #1051~Stale Proposals
This section contains pending changes that may not need feedback from the meeting participants, unless someone explicitly asks for it during the meeting. These changes are usually waiting for implementation work to happen to drive more feedback.
Waiting for interop
This section contains changes that have been conceptually ACKed and are waiting for at least two implementations to fully interoperate. They most likely don't need to be covered during the meeting, unless someone asks for updates.
channel_reestablish#934~Long Term Updates
This section contains long-term changes that need review, but require a substantial implementation effort.
