Jihoon:All right, hello everyone, welcome to Fossil breakout number 25.
00:07:01
Jihoon:I've prepared 3 agenda today, 4…
00:07:05
Jihoon:Yeah, hello, Stefan. The first one is…
00:07:09
Jihoon:A fossil has CFI for HECA.
00:07:12
Jihoon:So, we can talk a little bit about it. And then, as always, we can move on to development updates.
00:07:20
Jihoon:And then, as a last one, I haven't updated the GitHub issue yet, but I just wanted to ask, what do we think about, like.
00:07:31
Jihoon:when to have the next breakout call, because some people might have some vacation for next week. Yeah, that's the third and last agenda.
00:07:41
Jihoon:So… Yeah, let's jump into the first one. So, you know, as everyone knows.
00:07:49
Jihoon:Or you might know, Fossil has CFIs for HECA, and…
00:07:54
Jihoon:there will be the headliner process begins on January 8th.
00:08:01
Jihoon:It will last for a month, and then we will pick the headliner for HECA.
00:08:08
Jihoon:Here's the… Ethereum Magician Post, if you want to learn more details.
00:08:16
Jihoon:Let me share it in the chat.
00:08:21
Jihoon:I know that it's not done yet, but I just want to say thank you, everyone, who has been researching and developing fossil
00:08:32
Jihoon:voicing out for fossil… Attending ACD calls, and also breakout.
00:08:39
Jihoon:Talking to many people in various channels.
00:08:42
Jihoon:Sometimes it goes contentious unexpectedly, whether you are pro or against Fossil sharing your constructive feedback.
00:08:52
Jihoon:Has been… and will be helpful.
00:08:55
Jihoon:We're not done yet, but we're doing a great job, I'mma say.
00:09:01
Jihoon:We have 2 months more to go to SFI Fossil, and then many months to go to ship it, but we got this. Thank you.
00:09:11
Jihoon:Yep, so next up, development updates.
00:09:16
Jihoon:Maybe I can go first. I've rebased the EL spec, I mean, execution spec, from Osaka to Amsterdam.
00:09:28
Jihoon:Here's the link if anyone wants to take a look into it.
00:09:31
Jihoon:And… yeah, that's pretty much it from my end. Does anyone have anything to share?
00:09:53
Jihoon:Great, so Lowestar has rebased to the latest flu.
00:10:08
Jihoon:Did you try interop between wrath and…
00:10:14
Jihoon:Aragon, using this lowest star image.
00:10:24
Faheel:I, I tried, before, Lodestar got rebased.
00:10:30
Faheel:So, I'll, I'll try again with, after, after the rebates, yeah.
00:10:43
Faheel:the issue was that, like, there was, like, some data availability, problems which it was running into, the, Lodestar node, but, after I disabled, like, the blobs, spamming it, it worked.
00:11:00
Faheel:So… Yeah, I'll just check, recheck again, see if it's working with the new image.
00:11:08
Jihoon:Got it, it sounds like it should work, because blob is something that we don't touch in fossils, so…
00:11:16
Jihoon:Can you also share your Kurtosis config?
00:11:21
Faheel:Yeah, I'll… how do I share it? It's on…
00:11:27
Jihoon:I think you can just share it.
00:11:30
Jihoon:I mean, you can upload it to your… yeah, you can upload it to your GitHub, or if you just prefer to share
00:11:36
Jihoon:script, just sharing in the, Discord channel.
00:11:40
Faheel:Okay, okay, yeah, I'll link it, okay.
00:11:43
Matthew Keil:Yeah, that you could when you…
00:11:45
Matthew Keil:When you get any error messages or any DA issues, do me a favor and just DM them. I'd love to see what you're running across.
00:12:14
Jihoon:Do you have any other update? Yes, please?
00:12:18
Pelle Krabbenhoeft:Not so much, Sean.
00:12:20
Pelle Krabbenhoeft:Sorry. Not so much on REF, but I've been working on the sidecar to try to get some more data on sensor transactions. So, I have the…
00:12:33
Pelle Krabbenhoeft:like, the MVP for that working. I've just been using a free…
00:12:39
Pelle Krabbenhoeft:RPC APIs and stuff, just to test it, so I will eventually need… I'm trying to get my own node running right now, or I may need someone else's RPC node to do some real testing with it, but, I'm not sure if I'll have enough storage, but we'll see.
00:13:02
Jihoon:Do you have any article that lays out your research direction?
00:13:10
Pelle Krabbenhoeft:I don't… sorry. I don't have anything right now, but I could definitely work on something. Right now, it's just a real basic proof of concept, just trying to see if I can, what I can find.
00:13:26
Jihoon:Yeah, sounds great. I think it'll be really nice if you can, you know, make… write… write it down, then I can ask… I'm gonna review it myself, of course, but I'm gonna also ask other… other researchers to review it, so then we can elaborate it, I mean, improve it. So, yeah, if you are interested.
00:13:47
Pelle Krabbenhoeft:Yeah, sounds great.
00:14:25
Jihoon:Alright, it seems nuts, so I think we can move on.
00:14:29
Jihoon:So… Last but not least, I just wanted to ask,
00:14:37
Jihoon:Yeah, do we wanna cancel our next breakout call? Wait.
00:15:06
Jihoon:Right, so… until January 5th?
00:15:10
Jihoon:There will be no ACD call, except this… the one that we have this week.
00:15:27
Jihoon:Yes, next month is planned for… planned on the 30th of December.
00:15:46
Jihoon:we can cancel next one, which was scheduled on the 30th of December, which is also in line with our ACD schedule.
00:15:55
Jihoon:Just wanted to ask one more time if…
00:15:58
Jihoon:People are preparing something to share in two weeks.
00:16:04
Jihoon:Otherwise, we can just cancel next one and see in… 4 weeks, which should be…
00:16:20
Katya:Yeah, if we cancel this December 30, it means that we, won't meet before January 8th, alright? So…
00:16:31
Katya:Before this HECA process decision, or…
00:16:40
Jihoon:Are you asking… So… I… do you have…
00:16:51
Katya:I always have concerns, like, do we need to meet before, before this HECA process, or not, or…
00:17:00
Matthew Keil:Bite like heck, we're gonna go! Yay!
00:17:04
Jihoon:Yeah, so, I think it should be fine, because it is just the beginning of the process, and the process will last for a month, and it is collecting
00:17:20
Jihoon:that people want to propose for the headliner for HECA, it is not the process that we select for the headliner, so I think it should be fine. But of course, like.
00:17:30
Jihoon:If you want to discuss something, or if you want to share something, you can always share it in the Discord, so that people can see it.
00:17:38
Jihoon:Or, if you want to discuss something with me, I'm very reachable, so… yeah.
00:17:48
Jihoon:Yeah, so we had many a thumbs up for canceling next one, so I guess we can see on the…
00:17:57
Jihoon:And… yeah, there's… That's all that I've prepared for today. Does anyone have anything to share or discuss?
00:18:17
Jihoon:Going once… Going twice… Alright, we can go ahead and wrap this up.
00:18:25
Jihoon:Ollie, yeah, thank you everyone joining this call. I hope you guys have a great…
00:18:32
Jihoon:End of year, and see you guys in 4 weeks!
