258 2019-02-25T18:37:21  <provoostenator> luke-jr: good news, for now: I ran the numbers back to before SegWit and if you look *per bit* we can stil use the 50 out of 100 blocks threshold for warnings.
259 2019-02-25T18:38:04  <provoostenator> Afaik the protocol doesn't support signalling by rotating bits, so that shouldn't be a violation.
260 2019-02-25T18:38:17  *** Zenton has quit IRC
261 2019-02-25T18:39:01  <luke-jr> provoostenator: what do you mean?
262 2019-02-25T18:39:52  <provoostenator> Alerts are currently triggered when 50 out of 100 recent blocks have any unexpected bit set, even if it's a different bit in each of those blocks.
263 2019-02-25T18:40:24  <luke-jr> hmm, that's weird. fixing that does make sense
264 2019-02-25T18:40:26  <provoostenator> If we change that to tracking each bit individually, then there wouuld have been no alerts expect for SegWit and BIP91.
265 2019-02-25T18:40:31  <luke-jr> gotta run, bbiab
266 2019-02-25T18:40:39  <sipa> we already track each bit individually
267 2019-02-25T18:40:52  <provoostenator> sipa: the activation logic does, the alert logic doesn't
268 2019-02-25T18:40:58  <sipa> yes we do
269 2019-02-25T18:41:14  <sipa> (separate from the warning logic under discussio nnow)

272 2019-02-25T18:43:02  <provoostenator> We check if each block has an unexpected value. Any unexpected value.
273 2019-02-25T18:43:08  <sipa> yes, i know
274 2019-02-25T18:43:21  <sipa> i'm saying there is also another warning mechanism which does work per bit
275 2019-02-25T18:43:45  <provoostenator> Ah yes, the one that warns some new rule is active.
276 2019-02-25T18:43:57  <provoostenator> But that's not the one causing all the false positive alerts afaik.

280 2019-02-25T18:47:58  <provoostenator> The nUpgraded warning says "It's possible unknown rules are in effect", but that's only possible if a lower threshold or some other upgrade mechanism than BIP9 is introduced.

291 2019-02-25T19:08:26  <MarcoFalke> Is there any chance that there will be a softfork deployed not via BIP9?
292 2019-02-25T19:09:31  <MarcoFalke> I doubt it and I think the changes in #15471 are pretty minimal to get into 0.18.0 as a bugfix

294 2019-02-25T19:09:56  <wumpus> I also have the feeling this whole thing is overblown
295 2019-02-25T19:10:26  <wumpus> this warning is actively dangerous to users, and it would be good to disable it for 0.18, even if a better approach will be added later
296 2019-02-25T19:13:19  <MarcoFalke> agree
297 2019-02-25T19:16:45  <provoostenator> Yeah, the per bit counting is easier said than done.
298 2019-02-25T19:17:14  <sipa> I don't think it's hard, but i agree it's probably too much for 0.18 at this point
299 2019-02-25T19:18:06  <wumpus> I also wonder how much it matters, it's not that BIP9 is reliable anymore for those bits

301 2019-02-25T19:20:53  <provoostenator> It's hard to get a good signal to noise ratio to detect potential soft forks that could be activated soon.
302 2019-02-25T19:25:59  <adiabat> maybe if you see a bunch of non-standard txs?  also gameable but at some cost to miners
303 2019-02-25T19:26:45  <adiabat> though I guess that's after the fact, not for something that will be activated soon
304 2019-02-25T19:26:47  <wumpus> in *practice* it's easy because we know what bits the miners have chosen to use

321 2019-02-25T20:15:28  <MarcoFalke>  BIP320 could make sense to make it explicit, but that can be done for 0.19 or not at all

333 2019-02-25T20:56:24  <sipa> and bip32 only supports compressed keys, iirc
334 2019-02-25T20:57:12  <sipa> oh, that's not explicitly spelled out it seems

337 2019-02-25T20:59:11  <sipa> in any case, if the key is compressed, use the compressed serialization - otherwise use the uncompressed one :)
338 2019-02-25T21:00:07  <sipa> but xpub serializations always uses compressed... so integrating bip32 with uncompressed keys seems hard in any case
