< articmine > Hi

< vtnerd > hi

< boog900 > hi

< ack-j:matrix.org > Hi

< jberman > waves

< jeffro256 > Howdy

< rucknium > 2. Updates. What is everyone working on?

< jeffro256 > me: carrot_core reviews, Carot spec changes, and hot-cold PR seraphis-migration/monero#52. Did a lot of big changes to that PR

< jberman > some upstream PR review, and have started up again working on Serai

< vtnerd > me: finally making a lws signed 1.0 release in the next couple of days (hopefully the last bug fix was just pushed); working on monerod serialization; reviews

< jpk68:matrix.org > Me: worked on replacing GNU Readline, updating and reviewing PRs, doing some hardware wallet testing

< rucknium > me: Wrote a draft of methodology for using monerism to estimate the effectiveness of spy node adversaries: https://gist.github.com/Rucknium/ba230a2bab8a446d0997b7b002bf3af6

< rucknium > 3. FCMP++ to-do list status. Programming tasks (seraphis-migration/monero#53). Reviews and audits (https://cryptpad.fr/sheet/#/2/sheet/view/yPVIUywwA9-deE9VF6GYm9bXbPdCerdST3UDEEfBxcM/embed/). FCMP++ Integration Audit Overview (seraphis-migration/monero#294). Network upgrade [... too long, see https://mrelay.p2pool.observer/e/-cPd5KYLLTJvdW5y ]

< ack-j:matrix.org > MAGIC: set up an automated security review of monero PRs

< ack-j:matrix.org > https://github.com/xmrack/monero-review/issues

< gingeropolous > me: server maintenance. spinny 40TB lives on. optane drives FTW. contemplating another CCS. Fixing / improving monerosim.

< vtnerd > ack-j:matrix.orgthese are automated AI reviews? will need to bookmark this

< jberman > boog900:monero.social reviewed and approved the tx relay v2 major changes over here seraphis-migration/monero#450 (I still need to respond to that last comment there, but minor point). So that one is cleared for beta stressnet v3

< gingeropolous > me: contemplating if a ccs could cover a tesla powerwall (or equivalent) so we can stop having these damn outages ....

< ack-j:matrix.org > vtnerd:monero.social: yes. I have opus-5 scan a new pr from a queue every 30 minutes. Each time the pr’s hash changes it gets back inline for the queue

< jberman > jeffro256:monero.social made good progress on hot/cold wallets looks like, which we want in before stressnet v3 as well

< slowbeardigger:matrix.org > ack-j:matrix.org: Is it there any consideration of switching AI models?

< slowbeardigger:matrix.org > Claude models got a little bit “worse”

< jberman > Re: Research Tasks. The current remaining major task is having circuit + gadgets impl re-audited, and the fcmp-plus-plus audited. We're currently fielding quotes and talking to candidates answering questions etc.

< jeffro256 > I don't have much to add except that review and upstreaming is ongoing

< rucknium > Anything more on this topic?

< rucknium > 4. Relative locks with FCMP++ (monero-project/research-lab#161).

< rucknium > After the meeting, loop.ster:matrix.org said:

< rucknium > > Don't get me wrong, I am interested in pursuing this, it's about how much time I can spend on it. If it's completely pro bono -- my working assumption --, it's like 10% of my time, tops, and I'll be using AI to help accelerate things. So I can't commit to some deadline of "produce a spec by XX date or else timelocks don't get merged".

< rucknium > > What's encouraging is that there wasn't anyone against merging the time locks from what I could tell, so that's a very positive indicator.[... more lines follow, see mrelay.p2pool.observer/e/ur6U6qQLdzdNQXVF ]

< rucknium > And that mrelay link is a 404 for me now. Can anyone else see it?

< slowbeardigger:matrix.org > 404 for me as well

< rucknium > Ah, I can find the old Matrix chat room:

< rucknium > > Basically what I can offer is that if there's a general understanding that I am working on a spec, as time permits, along with the idea that relative locks probably do get merged -- that could work. That way we're not stuck at point 0, and in a month or so, we can compare notes again and maybe we're at a point where things can solidify a bit.

< jberman > One point I was kind of getting at: I think even work on this spec would potentially be a solid candidate for a CCS proposal. It would be helpful Research to help solidify adding features to Monero's consensus

< loop.ster:matrix.org > oh I see. I read it as, write the spec and then maybe..

< jberman > nay, sorry I was unclear

< loop.ster:matrix.org > cool, well I suspect I'll have some cycles next week to work on grease. I didn't move anything fwd this week

< jberman > my main point being I think that continuing on the path of exploring working with that feature would be appreciated

< rucknium > Any more discussion of this topic?

< loop.ster:matrix.org > nothing from me

< jberman > same, thank you loop.ster:matrix.org

< rucknium > 5. FCMP beta stressnet (https://github.com/seraphis-migration/monero/releases/). Version 3 launch checklist (seraphis-migration/monero#415).

< jberman > It's just hot/cold wallet stuff now, we're working on it

< jeffro256 > Al the major changes from j-berman's review are done AFAICT, just renamings left

< rucknium > Thanks, jberman:monero.social and jeffro256:monero.social .

< rucknium > Looks like this is going to be a short meeting.

< rucknium > We can end the meeting here. Thanks everyone.

< articmine > Thanks
