00:33 < kcalvinalvin> So I think I'm doing the right thing by writing new code for Utreexo then fitting it in btcd since a lot of libraries rely on the db
00:34 < kcalvinalvin> Is Core about the same? Seems like a *lot* of code tweaking for Utreexo
02:11 < kcalvinalvin> adiabat I made a list of goals that we should get/should be able to get before the Workshop in May. https://github.com/mit-dci/utreexo/issues/79 
02:12 < kcalvinalvin> Might have left some things out
02:13 < kcalvinalvin> As in, I should have put it in the list but forgot to
02:13 < kcalvinalvin> Also, the list isn't in any particular order

06:56 < adiabat> kcalvinalvin: yeah I think core is similar in that the database is everywhere...
06:56 < adiabat> so it's a pretty big code reshuffle to get it out of the way
06:57 < adiabat> but doing that in btcd first should at least give us an idea of how to do it
07:02 < kcalvinalvin> adiabat so on issue #79, I just said it'd be better if we start off with just ripping code off btcd
07:02 < kcalvinalvin> which is what I'm doing atm
07:02 < kcalvinalvin> but yea, should be easier with btcd. Though it still is a **huge** change
07:03 < adiabat> yeah I think a general sequence for this is:
07:04 < adiabat> 1: build a ValidateBlock() function call from patching together parts of existing code
07:04 < adiabat> that part might not be *that* bad.
07:04 < adiabat> just a big list of function calls and if any of them returns fasle, return false.  modeled on the one already there, but without database and with the utxos already on-hand
07:05 < adiabat> 2) re-org code internally to use that ValidateBlock() function, while still keeping everything in place (levelDB utxo set)
07:06 < adiabat> at that point, everything should still work.  Maybe part 2 seems useless, but I think it's helpful to have
07:06 < adiabat> then 3) pull out the levelDB parts to gather utxo arguments for the ValidateBlock() function and replace with utreexo
07:09 < adiabat> in terms of the github issue, I think #1 bridge node is the easiest / closest to done
07:09 < adiabat> we already pretty much have it, if you don't need to serve "classic" (maybe not the best term :) nodes
07:09 < adiabat> I think it's fine to only have the brige node talk to compact state nodes (CSN)s
07:10 < adiabat> beacuse if there's a handshake in the beginning, can just switch which binary you had that connection off to, run 2 alongside
07:10 < adiabat> but yeah eventually integrate them, but that can be done whenever later
07:11 < kcalvinalvin> Could you say this again on Github since I don't think most will see this
07:11 < adiabat> sure
07:12 < kcalvinalvin> And searching through irc is a pain...
07:15 < kcalvinalvin> Ah the term "classic" may not go well yeah haha.
07:19 < adiabat> I mean we can just start calling current bitcoin nodes bitcoin classic...
07:19 < adiabat> but could be confusing
07:19 < adiabat> a word I quite like is "legacy"
07:19 < adiabat> it's ultra presumptive
07:20 < adiabat> "legacy bitcoin nodes store the utxo set in leveldb"
07:40 < kcalvinalvin> "outdated"
07:40 < kcalvinalvin> "outdated bitcoin nodes store the utxo set in leveldb"
09:31 < kanzure> re: searching through IRC being a pain, i could publish irc logs for this channel if there's interest.
09:31 < kanzure> would be hosted on http://gnusha.org/ next to the other logs

20:51 < kcalvinalvin> kanzure yes that would be great
20:52 < kcalvinalvin> at the moment its just crappy script I made to push to github every midnight
23:30 < adiabat> kanzure: yeah that would be cool
23:30 < adiabat> also-
23:31 < adiabat> kcalvinalvin: don't think I can make 9am call tomorrow (today) - maybe we can do evening eastern time, or wednesday morning
23:31 < kcalvinalvin> adiabat haha so when are you good
