16:00:28 <abubakarsadiq> hi
16:00:28 <fjahr> There are no pre-proposed meeting topics this week. Any last minute ones to add?
16:00:30 <yancy> hi
16:00:38 <pinheadmz> hi

16:01:13 <andrewtoth> hi
16:01:41 <dergoegge> hi
16:01:58 <fjahr> Ok, starting with the WGs, in reverse order for a change ;)
16:02:00 <fjahr> #topic Net Split WG Update (cfields)
16:02:23 <cfields> Attention has been elsewhere, no update this week.
16:02:43 <fjahr> #topic Silent Payments WG Update (Novo)
16:03:01 <Novo> Not a lot has changed
16:03:25 <Novo> I have a few ideas to try, real-or-random mentioned trying out parallelisation
16:03:41 <Novo> I want to see what I can achieve with this
16:04:42 <Novo> I have a LabelSet bitcoin-core implementation branch and some testing shows that it is slightlity faster than the Bip approach at scanning real mainnet blocks
16:05:51 <Novo> But this testing was done with only two labels, I haven't done testing with higher labels, but I'm pretty sure the slight difference will disappear with a few more labels
16:06:31 <sipa> hi
16:06:42 <Novo> I've got nothing else to share
16:07:03 <fjahr> Thanks Novo!
16:07:05 <fjahr> #topic Benchmarking WG Update (l0rinc, andrewtoth)
16:07:12 <andrewtoth> willcl-ark added some more benchmarks via benchcoin in #31132. Got some good review on the split off PRs.
16:07:16 <corebot`> https://github.com/bitcoin/bitcoin/issues/31132 | validation: fetch block inputs on parallel threads 3x faster IBD by andrewtoth · Pull Request #31132 · bitcoin/bitcoin · GitHub
16:07:22 <andrewtoth> l0rinc mentioned he will be here later, so maybe he has more to add. #32407 and #34253 were merged.
16:07:23 <pinheadmz> help
16:07:24 <corebot`> https://github.com/bitcoin/bitcoin/issues/32407 | . by AlnetharyT · Pull Request #32407 · bitcoin/bitcoin · GitHub
16:07:28 <corebot`> https://github.com/bitcoin/bitcoin/issues/34253 | validation: cache tip recency for lock-free `IsInitialBlockDownload()` by l0rinc · Pull Request #34253 · bitcoin/bitcoin · GitHub
16:07:36 <andrewtoth> pinheadmz: how can I help?
16:07:37 <l0rinc> hi
16:07:53 <pinheadmz> ugh you can remind me to click on the right temrinal before typing
16:08:00 <andrewtoth> will do
16:08:07 <andrewtoth> that's it from me unless l0rinc has more
16:08:14 <l0rinc> I will add a few stuff later, let's continue
16:08:21 <fjahr> #topic Kernel WG Update (sedited)
16:09:08 <sedited> alexanderwiederin opened a draft RFC for a new CChain data structure: https://github.com/bitcoin/bitcoin/pull/34424
16:09:14 <sedited> stickies-v is making progress on the logging PR: https://github.com/bitcoin/bitcoin/pull/34374
16:10:00 <sedited> we also integrated header processing in some of the kernel library language wrappers
16:10:06 <sedited> that's all.
16:10:42 <fjahr> #topic Fuzzing WG Update (dergoegge)
16:11:03 <dergoegge> nothing from my side
16:11:18 <fjahr> #topic Cluster Mempool WG Update (sdaftuar, sipa)
16:12:13 <sipa> Not many updates. I'm working on the cost model PR (#34138), but focus remains the deterministic ordering: #34257
16:12:15 <corebot`> https://github.com/bitcoin/bitcoin/issues/34138 | Cluster mempool: more accurate cost model for SFL by sipa · Pull Request #34138 · bitcoin/bitcoin · GitHub
16:12:16 <corebot`> https://github.com/bitcoin/bitcoin/issues/34257 | txgraph: deterministic optimal transaction order by sipa · Pull Request #34257 · bitcoin/bitcoin · GitHub
16:13:13 <sipa> That's it for me.
16:13:23 <fjahr> Anything else to discuss?
16:13:26 <fjahr> PSA: next asmap built happens again in one week: https://github.com/asmap/asmap-data/issues/42
16:13:53 <fjahr> Also the v31 feature freeze is 4 weeks out afaict, not sure if there is something to discuss right now though
16:14:39 <l0rinc> Let me give a quick update
16:14:50 <l0rinc> #34253 was merged, we don't expect the change to be measurable but it simplifies the call sites and helps with follow-ups like #34054
16:14:52 <corebot`> https://github.com/bitcoin/bitcoin/issues/34253 | validation: cache tip recency for lock-free `IsInitialBlockDownload()` by l0rinc · Pull Request #34253 · bitcoin/bitcoin · GitHub

16:15:07 <l0rinc> #34207 was also merged, this has been in review in various forms for at least a year now - this leads naturally to the next steps in #34280, e.g. #33018

16:15:23 <l0rinc> I've measured the script restoration benchmark on most of my machines and sent it to Julian, he's updated the plots with the new data.
16:15:27 <l0rinc> that's it from me
16:16:13 <fjahr> Thanks l0rinc! Anything else?
16:16:20 <l0rinc> no, thanks
16:16:52 <fjahr> I meant if anyone else has a topic :)
16:17:09 <l0rinc> I know, but still nothing from me :D
16:17:35 <stickies-v> hi
16:17:43 <furszy> fastest meeting ever, thanks fjahr!
