Meeting Notes:

Agenda

Manuel PM’ing milestones:

• Define 3 priorities for all the milestones together in the team calls. At the moment for alpha 1 only the “fix doc.rs” is missing; for alpha2 first two priority points ongoing). For alpha.3 and 4 priorities still to be defined (coin selection, txbuilder…)
• Check with Manuel what goes in the alpha.2 release
• Having milestones on all projects

BDK 1.0 milestones and timeline

• Moving the #1015 and #1022 from alpha.1 milestone to alpha.2 (asked but didn’t get feedback).
• Waiting for evan to confirm that we don’t miss anything else in alpha.1. If not, just the “fix doc.rs” is missing, then it’s ready

BDK Design Club

• Probably not going to happen this week

Release Pinning suggestion from Tobin

• do it via CI instead of in the cargo.toml?
• vlad will make an issue and investigate

esplora client

• tnull suggested need to expose error message
• only gives status code now
• issue 47, vlad will take a look

Top BDK 1.0 PRs and issues

• Upgrade rust-bitcoin to 0.30 and miniscript 0.1 (Daniela is working on it in #1023)
• #1011 PR approved, needs test
• #1002 on linked-list, need to understand if there is something missing (tests, blocking points…)

Top Maintenance PRs and issues

0.29.0:

• Add issues for upgrade rust-bitcoin to 0.30 and miniscript 0.1
• Problem with address caching (#985). It is a big change, not many complains about it - only galoy because they have tons of addresses. To be decided if it’s worth to be worked on right now. It can have some impact on the LDK sync with esplora client, since BDK sync is taking something like 7 secs. There is some limitation on how esplora and electrum work. With 1.0 there could be the possibility to load balance on different esplora servers; probably not much faster but good for the rate limit.

0.28.0:

• Problem with the current implementation of compact block filters since it uses rocksDB and it has an issue with a feature that we don’t use. For Binding, it makes sense to go directly with the 1.0 version
• backport is done
• fix rocksDB audit is done
• we miss only the descriptor template [BIP 86] (Steve is going to have a look at it next week)

Minutes

• LDK last release so far so good
