- Async KV Store Persister #1470
- Two prios: redoing monitor tempfail api, and taking advantage of that with kvstorepersister trait that’s asynchronous
- Fixes sensei issues
- 2nd prio is fixing get_claimable_balance to work w revoked outputs from the counterparty, needs review
- In general we want to have a quicker release cadence

Developer support
- Arik + jeff presented at btc++ conf in austin on LDK. vid coming soon
- Gave a good overview of ldk, useful to get feedback from people too
- A couple people there used sensei for the hackathon
- The fact that we had fewer actual projects use ldk direction - there were 4 diff sponsors to the hackathon that were sponsoring prize money if you used their project. One was sensei tho, so that’s good.
Payment protocols
- Val’s update.. Can’t write and talk sorry
- Offline receive
  - Big win for mobile usage
  - Depends on OMs (onion msgs)
  - Depends on PTLCs (therefore depends on taproot)
  - Later this year, someone will need to sign up for this
Language bindings
- No specific update, matt’s been traveling
Taproot support
- Laolu sent out an update, linked in ln summit link below
Anchor outputs
- No update, wpaulino has been working on other smaller issues. But should be starting …
Lightning Service Provider (LSP)
- John carvalho: there’s biweekly lsp meetings, private for now. Mostly roy and our cto working on an initial basic spec. Once that’s going, we’ll evolve it and have discussions about what extra functionality needs to be added there, marketplaces, multiple lsps, but for now just trying to get it off the ground

validating-lightning-signer (https://gitlab.com/lightning-signer/validating-lightning-signer)
- Devrandom: working on allowing the signer to be intermittently connected. Currently no way to do that, we just panic/kills the process. Intermittently available signers are an important use case for VLS and in general for sensei too, all of the signers are going to be intermittent
- Ken sedgwick: working with SoB mentee on demo, myself working on how to run trial mainnet runs using CLBoss as an example use pattern
BDK-LDK / Sensei (https://github.com/johncantrell97/bdk-ldk)
- Jcantrell: bdk-ldk thing, i think it was elias who was talking abot using that as a base, upstreaming it into some kinda ldk-based lib for a simplified api with electrum. Not being worked on by me, so either removing it from this list or migrating it to whatever inside of ldk uses it.
- For sensei, not much. Successfully updated to ldk 108 and bdk 19.
- Talking to joost at bottlepay, he’s setting up a pathfinding benchmarking project. Reached out cuz he wasn’t sure the best way, wanted grpc apis. I told him he could use sensei, tho wasn’t sure it’s the most honest representation of ldk pathfinding. He’s open & wants the process to be fair, may want to ask you guys how to expose ldk pathfinding so it’s a fair comparison. Not sure best way to talk to him
