07:17 < BlueMatt> cfields: re: #9609 yea, I know you dont want to use fSuccessfullyConnected in net_processing after 0.14, but its so much cleaner to use that appropriately now and split it out into CNodeState in 0.14, so i figured I'd suggest it :)

08:16 < cfields> BlueMatt: i tried hard to disagree but couldn't :)
08:17 < cfields> I do want something net-only going forward, but I'll do that next. Once we're forked, I have a flood of changes. I'll just pile that on.
08:19 < BlueMatt> heh, ok
08:22 < cfields> gmaxwell: are you ok with that? I see you acked as-is, but I think BlueMatt's suggestion only locks us down tighter
08:22 < cfields> note that it is a change in p2p behavior though. Pretty sure the current network allows for not sending a VERACK with not much downside
08:22 < cfields> (other than obviously not getting new serialization)
08:23 < BlueMatt> I'd hope we consider that undefined behavior?
08:24 < cfields> i would certainly say so
08:24 < cfields> i think the only quasi-valid real-world change would be addr races

08:25 < BlueMatt> have we ever sent addr messages before verack?

08:27 < cfields> not us, i meant other nodes maybe sending verack/getaddr out of order

15:23 < CubicEarth> The biggest issue I'm aware of with lightning is the 'bank run' scenario, with not enough on-chain capacity for people to dispute fraud before the block-window closes, as could be the case if a hub tried to steal funds from millions of people. Am I understanding correctly this is an issue? Is there a viable solution?
15:24 < sipa> not sure this is the best place to discuss it, but i think that is the main reason why we shouldn't accept very large hubs
15:27 < CubicEarth> sipa: thanks. what's the better place for this topic?
15:27 < sipa> lightning mailing list, perhaps?
15:29 < gwillen> CubicEarth: there is a #lightning-dev channel

15:31 < gmaxwell> CubicEarth: there are proposals that reduce that exposure, e.g. timestop.. where CSV's counting is not monotone but can slow down when the network is full of high fees.  But it's not really needed for basic operation of the system.
15:32 -!- waxwing [~waxwing@113.189.78.210] has quit [Ping timeout: 252 seconds]     
15:34 < CubicEarth> gmaxwell: cool. I'll read up.
15:38 < gmaxwell> I don't know if there is much of a writeup of timestop beyond the observation that CSV clock doesn't have to tick once per block.. we setup the CSV spec so there is extra room to signal other kinds of ticking.
15:38 < gmaxwell> Joseph poon had some ideas on particular incentive compatible timestop schemes but it hasn't had a lot of research.
15:42 < CubicEarth> It seems like something that needs to be solved or with time, systemic risk will develop

21:48 < gmaxwell> cfields: re your earlier question-- show me the code. I'm unsure about matt's suggestion because I can read it in ways that wouldn't be good.  E.g. if the recieve for a verack unconditionally set fsuccessfullyconnected true then something that veracked without ever going through version could be successfully connected.
21:48 < gmaxwell> assuming that it doesn't do anything stupid, it's fine
21:48 < gmaxwell> and I think it would be fine to clamp down the handshake and require the states be followed as expected...
21:49 < gmaxwell> not just fine but good: I could imagine us having some uninitlized something as a result of getting that wrong.
21:50 < gmaxwell> cfields: but I will gladly review whatever comes up when it comes up.
