197 2017-09-18T16:34:46  <RealM9> I know nobody here thinks about a way how to solve this, but i think it's a huge problem. Miners can spam network for free, if they work togather. Think about this. And antpool mines another VIP block
198 2017-09-18T16:37:55  <RealM9> 14 MB mempool data of 100-140sat/byte TXes

200 2017-09-18T16:39:45  <andytoshi> miners can't spam any more cheaply than anybody else. 14 Mb at 100sat/byte is like $50000

203 2017-09-18T16:40:16  <lvmbdv> and proof-of-work assumes the expenses of spamming the network would drive bad guys away
204 2017-09-18T16:40:30  <RealM9> Well remember that mining is centralized and miners get fees
205 2017-09-18T16:41:03  <RealM9> And some big block conference is happening soon
206 2017-09-18T16:41:34  <andytoshi> #bitcoin please
207 2017-09-18T16:42:03  <RealM9> Maybe core should create some anti-spam mechanisms on 0.15.1
208 2017-09-18T16:42:44  <Chicago> ... until when?  Until Micro-Bitcoins are a common denomination?
209 2017-09-18T16:42:54  <RealM9> Because, you know that S2X fork is coming and if miners will spam, they will do it NOW. Before S2X
210 2017-09-18T16:42:55  <gmaxwell> this is stupid. I haven't seen any evidence of spam, just people aggregating txs at very low feerates.
211 2017-09-18T16:43:30  <RealM9> Isn't this evidence https://i.imgur.com/oCANzXW.png ?

213 2017-09-18T16:45:29  <gmaxwell> The only 'fix' to spam needed would be a magic want to stop people from putting up graphing sites that panic people about things the system already handled.
214 2017-09-18T16:47:08  <RealM9> What if they started spamming for let's say, 2 weeks. Their big-block agenda would get only more popular and S2X would be a solution
215 2017-09-18T16:48:15  <RealM9> Yeah, but there aren't really much to do about it without risking to delete legitimate TXes from mempool

217 2017-09-18T16:48:22  <gmaxwell> I looked last night when people first started squaking about that and it appeared to be due to txs like https://blockchain.info/tx/87cd70a1859f1029d7619ca6b745232e34b8627fc7ac1e2e50a4b2705c6aba48 which are just plain aggregation tx
218 2017-09-18T16:49:08  <gmaxwell> RealM9: What if?  who cares. You just pay a slightly higher feerate than them and they stop existing as far as you're concerned.
219 2017-09-18T16:50:15  <gmaxwell> For every transaction paying feerate X they display by one block they have to pay x over again in fees. Even if it's a miner doing it the result is astronmically expensive.

357 2017-09-18T22:58:40  <goatpig> are there still milestones hardcoded in for boostrapping the chainstate db?
358 2017-09-18T23:00:36  <luke-jr> checkpoints? yes
359 2017-09-18T23:00:50  <luke-jr> although in Core, they haven't been updated in a long time (intentionally)
360 2017-09-18T23:03:37  <gmaxwell> "for boostrapping the chainstate db?" for that, no there has never been anything like that.
361 2017-09-18T23:05:40  <goatpig> i mean the set of milestones to check hashes instead of signatures for early chain data
362 2017-09-18T23:05:46  <goatpig> luke-jr: why have they not been updated?
363 2017-09-18T23:07:27  <sipa> goatpig: we want to get rid of checkpoints
364 2017-09-18T23:07:52  <sipa> their functionality has been replaced by headers-first sync & assumevalid
365 2017-09-18T23:08:20  <sipa> (almost, but not entirely - they still protect against a weak memory exhaustion attack, but old checkpoints suffice for that)
366 2017-09-18T23:08:45  <goatpig> ah so the feature has been replaced
367 2017-09-18T23:08:56  <sipa> assumevalid is maybe what you're after - it's a configurable block hash we know has valid signatures in its history
368 2017-09-18T23:09:07  <goatpig> yeah that';s what im after
369 2017-09-18T23:09:08  <sipa> but it doesn't force the client to only accept that chain (as checkpoints did)
370 2017-09-18T23:09:23  <sipa> they just bypass validation IF that chain we to otherwise be validated
371 2017-09-18T23:09:34  <goatpig> but there is a default hardcoded value in the code that's being updated now?
372 2017-09-18T23:09:55  <sipa> that's correct
373 2017-09-18T23:10:02  <goatpig> ok that's what i wanted to know

380 2017-09-18T23:13:11  <gmaxwell> goatpig: these thigns do not fix a particular chain, and only have an effect if they're in our best chain and burried by a couple weeks work.
381 2017-09-18T23:14:11  <goatpig> you mean if you are exposed to a chain that branches before the assume valid hash and that it's longer than the assumed one, it would check all sigs in that branch regardless?
382 2017-09-18T23:14:18  <sipa> yes
383 2017-09-18T23:14:25  <goatpig> sure, makes sense
384 2017-09-18T23:17:03  <promag> in that case doesn't make sense to assume valid from the fork backwards?
385 2017-09-18T23:18:15  <goatpig> im guessing it does assumevalid up until the branch point, then drops the behavior as soon as it forks
386 2017-09-18T23:18:26  <sipa> promag: assumevalid=X means that script validation is skipped for any block that is an ancestor of X
387 2017-09-18T23:18:36  <sipa> so i think it does what you're saying
388 2017-09-18T23:18:50  <gmaxwell> sipa: no, not if the assumevalid block is not in the best chain.
389 2017-09-18T23:19:04  <gmaxwell> promag: potentially but thats a dumb situation:  Don't set the value on a fork and then there is no need for code to handle that case, nor need for tests to test it. :)
390 2017-09-18T23:19:48  <gmaxwell> but yes, I believe that what you suggest would be fine (other than the unnecessary complexity)
391 2017-09-18T23:20:09  <goatpig> gmaxwell: then what's the decision in case of a fork? don't forward the assumevalid hash past that fork point for ages?
392 2017-09-18T23:20:48  <sipa> goatpig: i'm confused
393 2017-09-18T23:21:29  <goatpig> gmax saying assumevalid does not afford you bypassing sig checks if the assumed valid hash is on the shortest branch of a fork
394 2017-09-18T23:21:37  <gmaxwell> goatpig: if its ambiguous what chain is correct for ages we have bigger problems.
395 2017-09-18T23:22:11  <achow101> goatpig: if the assumevalid block is not in your best chain, then you will be validating all signatures
396 2017-09-18T23:22:16  <gmaxwell> what I've been doing on updating them is setting it to a most recent block when I open the PR, and just checking that it's still in the chain by the time the PR is ready to be merged.
397 2017-09-18T23:22:23  <goatpig> therefor, how do you handle forks with that updating that hardcoded hash in the case there is a potential for the fork to sustain 2 semi equivalent branches (in term of work)
398 2017-09-18T23:22:33  <achow101> if the best chain changed to not include the assumevalid hash, then all blocks you have already been verified won't be re-verified
399 2017-09-18T23:22:34  <gmaxwell> if it were to fall out, oh well, sync would take somewhat longer. Not the end of the world.
400 2017-09-18T23:22:58  <goatpig> ok
401 2017-09-18T23:23:02  <goatpig> just curious about the whole mechanic
402 2017-09-18T23:23:55  <gmaxwell> goatpig: if something like that went on for weeks it would be doubtful if bitcoin would continue to exist at the end of such an event, regardless tweaking forward assumevalid wouldn't be a high priority. ... losing it entirely isn't that big of a deal.
403 2017-09-18T23:24:23  <goatpig> i get it
