2 2013-11-08 00:00:46 <TD> forrestv: the question is - what makes you think you can do the lookups faster than bitcoind
3 2013-11-08 00:00:54 ThomasV has joined
4 2013-11-08 00:01:44 <gmaxwell> td: bitcoind cannot do lookups of _spent_ coins (e.g. verifying the newly historic p2pool chain) fast without a seperate large index of historic outputs.
5 2013-11-08 00:01:44 <forrestv> TD, assuming the UTXO merkle tree idea were implemented, each transaction in every share could carry its merkle branch, which acts as proof that it's currently spendable
6 2013-11-08 00:02:24 <TD> gmaxwell: and how would p2pool solve that differently?
7 2013-11-08 00:02:58 <sipa> forrestv: you mean a merkle path for each of its inputs?
8 2013-11-08 00:03:09 <forrestv> sipa, yes, oops
9 2013-11-08 00:03:18 <sipa> that is no proof of spendability

11 2013-11-08 00:03:37 <sipa> just a proof of spendable-once-upon-a-time
12 2013-11-08 00:03:38 <forrestv> what do you mean?
13 2013-11-08 00:03:44 <sipa> it can be spent already
14 2013-11-08 00:03:51 <sipa> ugh
15 2013-11-08 00:03:53 <TD> sipa: he is talking about a merkle branch for a non-existant utxo tree

40 2013-11-08 00:26:30 <sipa> it sounds a bit biased and possibly not that bad... but it does make me want to reconsider moving away from sf entirely
41 2013-11-08 00:27:20 <gavinandresen> https://bitcoincore.org/ could start serving binaries, modulo DoS protection
42 2013-11-08 00:28:14 <gavinandresen> ⦠well, and we need somebody dedicated to making sure it stays secure
43 2013-11-08 00:28:25 <abrkn> whos the "third" guy on letstalkbitcoin all the time? theres the host and the female and one more

52 2013-11-08 00:30:22 <abrkn> its an audio show, pretty ok, but its very, very, very u.s. centric
53 2013-11-08 00:30:34 <abrkn> its like they dont know anything outside the u.s exists
54 2013-11-08 00:30:38 <ryan-c> I'm trying to build bitcoin from git, it's failing to find Boost::System. I have libboost-all-dev installed on ubuntu 13.10.

58 2013-11-08 00:32:02 <ryan-c> Oh, that issue is only 8 hours old
59 2013-11-08 00:32:12 <ryan-c> well i don't feel so bad about my google-fu now.
60 2013-11-08 00:33:14 <abrkn> the whole bitcoin foundation concept confuses me. they keep fronting gavin and saying they're hiring lobbyists in the u.s

66 2013-11-08 00:35:37 <abrkn> sipa: gavin is right, it's the wrong chan. i wanted to know what he thinks, but its not fair to ambush in -dev
67 2013-11-08 00:36:06 <gavinandresen> sipa: "fronting" means "promoting as spokesperson"

77 2013-11-08 00:38:42 <Evilmax> i am using "sendfrom" command in bitcoind
78 2013-11-08 00:38:48 <Evilmax> but it seems not work
79 2013-11-08 00:38:51 <Evilmax> why?
80 2013-11-08 00:39:00 <ryan-c> abrkn: It's a vm, so i can just respawn it with more mem
81 2013-11-08 00:39:24 <abrkn> ryan: give it a shot at 4gb
82 2013-11-08 00:39:26 <ryan-c> Evilmax: Can you elaborate on "seems not work"?
83 2013-11-08 00:39:33 <Evilmax> there is an alternative? i want not use "sendtoaddress" because i am afraid that, in this way, an account can spend all server balance

87 2013-11-08 00:40:01 <Evilmax> wait...i will write the error (i use curl)
88 2013-11-08 00:40:15 <ryan-c> Evilmax: You can try locking all the bitcoins you don't want to spend and then do a transaction
89 2013-11-08 00:40:25 <Evilmax> {"result":0.00000000,"error":null,"id":"t0"}
90 2013-11-08 00:40:48 <ryan-c> Evilmax: I suggest you try experimenting on testnet - I'd be happy to send you 100 testnet coins to play with.
91 2013-11-08 00:40:49 <Evilmax> i want that an account of my bitcoind daemon can move his coins but not all coins
92 2013-11-08 00:41:10 AndyOfiesh has left ()
93 2013-11-08 00:41:19 <Evilmax> on test net i can charge 100 coins?!
94 2013-11-08 00:41:24 <Evilmax> wow
95 2013-11-08 00:41:28 <abrkn> ryan: im just guessing here from compiling litecoind. i never compiled bitcoind from source
96 2013-11-08 00:41:49 <ryan-c> Evilmax: I can give you testnet coins for free. They're totally worthless for anything other than testing.

99 2013-11-08 00:42:05 <abrkn> whats confirmation time on testnet like these days?

102 2013-11-08 00:42:17 <Evilmax> please...first let me take a look to config file
103 2013-11-08 00:42:30 <ryan-c> Evilmax: You'll need to restart bitcoind in testnet mode.
104 2013-11-08 00:42:55 <Evilmax> maybe it doesn't work because "paytxfee=0.00" in config?

115 2013-11-08 00:44:27 <DonnchaC> Hi, I'm trying to create tx's spending from multisig address in python. I'm pretty sure I am generating my raw transaction correctly but I'm not sure whats going wrong (possibily with signing). When I try broadcast the fully signed tx blockchain.info tells me "Unable To find all tx inputs" - https://gist.github.com/anonymous/ac6b28a729b595d06c53
116 2013-11-08 00:44:34 <Evilmax> i use:
117 2013-11-08 00:44:36 <michagogo> cloud!uid14316@wikia/Michagogo|abrkn: basically, a little while ago someone pointed a very large amount (relatively) of hashpower at the testnet
118 2013-11-08 00:44:48 <michagogo> cloud!uid14316@wikia/Michagogo|so blocks usually don't get found until the 20 minute rule kicks in
119 2013-11-08 00:44:48 <Evilmax> account, destination wallet and amount
120 2013-11-08 00:44:59 <Evilmax> accounte name, dest wallet, amount
121 2013-11-08 00:45:09 <DonnchaC> Anyone see anything obvious wrong with my tx. I have spent far too long trying to figure this out already :)
122 2013-11-08 00:45:09 <ryan-c> how are you sending that?
123 2013-11-08 00:45:18 <Evilmax> by curl command
124 2013-11-08 00:45:20 <Evilmax> wait
125 2013-11-08 00:45:24 <Evilmax> i will past it there...
126 2013-11-08 00:45:47 <ryan-c> Evilmax: Why curl? bitcoind can issue RPC commands to the server.
127 2013-11-08 00:46:23 <Evilmax> curl -u user:pass -d '{"id":"t0", "method": "sendfrom", "params": ["user","dest wallet","amount"] }' http://ip:8332/

135 2013-11-08 00:48:24 <ryan-c> It needs to match an account name in your wallet.
136 2013-11-08 00:48:28 <Evilmax> i do not understand
137 2013-11-08 00:48:33 <Evilmax> yes
138 2013-11-08 00:48:37 <Evilmax> it matches
139 2013-11-08 00:48:54 <Evilmax> i wrote user, dest wallet and amount only as example
140 2013-11-08 00:49:02 <ryan-c> Evilmax: Try using bitcoind to issue the command

151 2013-11-08 00:52:10 <Evilmax> there is an alternative?
152 2013-11-08 00:52:41 <ryan-c> Depends what you're trying to do... normally sendtoaddress is used.
153 2013-11-08 00:52:42 <Evilmax> sendtoaddress, instead, move all daemon bitcoins
154 2013-11-08 00:52:53 <Evilmax> i need that it moves only bitcoins of an account
155 2013-11-08 00:53:00 <ryan-c> Why?
156 2013-11-08 00:53:06 <Evilmax> because my daemon
157 2013-11-08 00:53:10 <Evilmax> is a service

162 2013-11-08 00:54:56 <Evilmax> it works!
163 2013-11-08 00:55:10 <Evilmax> so...i have to get it working with curl command too

171 2013-11-08 00:56:43 <Evilmax> now this is not important

173 2013-11-08 00:57:02 <Evilmax> later i will think abount security
174 2013-11-08 00:57:25 <ryan-c> Evilmax: You should not be trying to run a service that other people store money in.
175 2013-11-08 00:57:44 <Evilmax> why?
176 2013-11-08 00:57:53 <lianj> whats the faceplam unicode symbol again
177 2013-11-08 00:57:55 <Evilmax> that is my intent :)
178 2013-11-08 00:57:57 <Evilmax> ehehe
179 2013-11-08 00:58:23 <ryan-c> Evilmax: With an "I'll think about security later" attitude you will get hacked. Your users will lose their money.

184 2013-11-08 00:58:46 <Zarutian> security much be integral part of you design
185 2013-11-08 00:58:47 <Evilmax> i will fix all security issue
186 2013-11-08 00:58:54 <lianj> m) <- good enough
187 2013-11-08 00:58:55 <Evilmax> but now i ask for this issue
188 2013-11-08 00:58:57 <phantomcircuit> Evilmax, what are you trying to do?
189 2013-11-08 00:59:05 <Evilmax> oh boys
190 2013-11-08 00:59:06 <ryan-c> Evilmax: Even if you think about security first, you need to hire a security expert (or even more than one) to check your work.
191 2013-11-08 00:59:06 <pigeons> think about security later https://inputs.io/
192 2013-11-08 00:59:17 <Evilmax> i am trying to host a btc wallet site
193 2013-11-08 00:59:24 <Zarutian> pigeons: hah! indeed!
194 2013-11-08 00:59:30 <phantomcircuit> pigeons, im not entirely convinced the security was the problem there
195 2013-11-08 00:59:30 <ryan-c> Evilmax: You are not qualified to do so. Do not try.
196 2013-11-08 00:59:55 <lianj> phantomcircuit: true
197 2013-11-08 00:59:55 <pigeons> Evilmax: relevant because they were also a hosted btc wallet site
198 2013-11-08 01:00:07 <lianj> phantomcircuit: at least not own app security per se
199 2013-11-08 01:00:12 <phantomcircuit> although the security was certainly not up to the level he claimed
200 2013-11-08 01:00:15 <Evilmax> ok...anyway i asked for help...not for this
201 2013-11-08 01:00:17 <ryan-c> Evilmax: I'm sorry to be harsh.
202 2013-11-08 01:00:18 <phantomcircuit> api keys as get parameters? wat
203 2013-11-08 01:00:29 <ryan-c> Evilmax: But it's what you need to hear.
204 2013-11-08 01:00:32 <Evilmax> just help me about my question
205 2013-11-08 01:00:37 <Evilmax> if it's possible
206 2013-11-08 01:00:47 <Evilmax> no Ry4an
207 2013-11-08 01:00:49 <Evilmax> ryan-c
208 2013-11-08 01:00:51 <lianj> phantomcircuit: convenience api
209 2013-11-08 01:00:55 <Evilmax> about sendfrom command
210 2013-11-08 01:01:04 <phantomcircuit> lianj, is it really that much harder to use post?
211 2013-11-08 01:01:11 <Evilmax> ok, do not worry
212 2013-11-08 01:01:13 <lianj> phantomcircuit: for some
213 2013-11-08 01:01:17 <Evilmax> i will try by myself
214 2013-11-08 01:01:24 <Evilmax> thank you, anyway :)
215 2013-11-08 01:01:26 <pigeons> what was the likely non-security problem phantomcircuit ?
216 2013-11-08 01:01:29 <ryan-c> Evilmax: Your users will get screwed.
217 2013-11-08 01:01:40 <Evilmax> and sorry my english
218 2013-11-08 01:01:41 <phantomcircuit> pigeons, do you know who TF really is? because i dont
219 2013-11-08 01:01:42 <ryan-c> pigeons: He's implying the hack was staged.
220 2013-11-08 01:01:45 <Evilmax> i am tired to translate
221 2013-11-08 01:02:00 <phantomcircuit> pigeons, "here you go anonymous internet person have my bitcoins, please dont steal them kthx"
222 2013-11-08 01:02:16 <lianj> ryan-c: oh that. maybe too. but we can say that for almost any btc hack
223 2013-11-08 01:02:26 <pigeons> phantomcircuit: i don't know him personally i know of a past scam of his. i see what you mean. i'll take it out of channel
224 2013-11-08 01:02:33 <kuzetsa> as an aside... I think perhaps some users might worry about the morality of a person who uses the name "evil" and doesn't consider security for other people's money a top priority.
225 2013-11-08 01:02:48 <phantomcircuit> kuzetsa, lol...
226 2013-11-08 01:02:59 <kuzetsa> particularly after the "pirate at 40" last year
227 2013-11-08 01:03:10 <gmaxwell> kuzetsa: ppft, it's not like anyone has ever been screwed over by someone named pirate or some guy named nefario.
228 2013-11-08 01:03:19 <lianj> kuzetsa: give me bitcoin i give you more back
229 2013-11-08 01:03:36 <kuzetsa> lianj: fortunately for me, I don't have a bitcoin to risk right now
230 2013-11-08 01:03:48 <kuzetsa> it's all invested in hardware :(
231 2013-11-08 01:03:57 <lianj> m(
232 2013-11-08 01:04:06 [\\\] has joined
233 2013-11-08 01:04:21 <phantomcircuit> gmaxwell, im fairly confident nefario didn't actually screw over anybody
234 2013-11-08 01:04:42 <gmaxwell> Anyone know what the deal is with coinbase randomly "refunding" payments of not-exactly-expected amounts to random prior to addresses apparently inferred from analyizing signatures and prior txouts?
235 2013-11-08 01:04:42 <ryan-c> I have been doing computer security work for a very long time. I would not trust myself to make a web wallet. You have to worry about stuff like "hosting provider hacked with 0day" when you're holding a bunch of bitcoins for people.
236 2013-11-08 01:04:59 <kuzetsa> yeah... I wasn't screwed by nefario... I opted in to having my contact info shared with the security issuer who then made it right :)
237 2013-11-08 01:05:02 <gmaxwell> phantomcircuit: I mean, if nothing else he managed to lose a ton of money via the double payments.
238 2013-11-08 01:05:06 <phantomcircuit> gmaxwell, it's for addresses associated with an invoice i think
239 2013-11-08 01:05:23 <phantomcircuit> gmaxwell, sure but that's nor malicious
240 2013-11-08 01:05:26 <phantomcircuit> not*
241 2013-11-08 01:05:42 <ryan-c> well, seems like 5GB ram is enough to build bitcoind
242 2013-11-08 01:06:05 <pigeons> well mr nefario got some vc money for a uk exchange
243 2013-11-08 01:06:12 <phantomcircuit> ryan-c, you can build with 512mb of ram but only if you do it with -j1
244 2013-11-08 01:06:27 <ryan-c> phantomcircuit: Hmm, I only had -j2

246 2013-11-08 01:06:29 <phantomcircuit> pigeons, except they only can do SEPA transfers like everybody else
247 2013-11-08 01:06:35 <ryan-c> well, it's compiled now
248 2013-11-08 01:06:45 <MC1984> why does it take so much ram to compile a 20mb program
249 2013-11-08 01:06:47 <phantomcircuit> pigeons, i'll be impressed if they can get a uk domestic account
250 2013-11-08 01:06:53 patcon has joined
251 2013-11-08 01:07:05 <kuzetsa> ryan-c: were you using the "-pipe" cflag or something? that's way more ram than I've ever used for compile without "-pipe" in my compiler toolchain
252 2013-11-08 01:07:16 <pigeons> i'm impressed with any bitcoin exchange that holds bank accounts
253 2013-11-08 01:07:24 <ryan-c> no, i was using mostly default compile settings.
254 2013-11-08 01:07:28 <warren> TD[away]: gmaxwell: forrestv: sounds like p2pool would benefit from something like: bitcoind validates an insufficient difficulty p2pool share is a valid block (except for the difficulty being insufficient).
255 2013-11-08 01:07:40 <phantomcircuit> pigeons, i'd bet they have an account at bzwbk, which isn't hard unless you really are doing something stupid
256 2013-11-08 01:07:50 <gmaxwell> warren: that may be useful but it doesn't work for old shares.
257 2013-11-08 01:07:51 <ryan-c> just had qt disabled and had the "non-portable-wallet" flag.
258 2013-11-08 01:07:55 <kuzetsa> ryan-c: "default" varies depending on which distro provided your toolchain
259 2013-11-08 01:08:04 <ryan-c> it's ubuntu 13.10
260 2013-11-08 01:08:04 <warren> crap.
261 2013-11-08 01:08:26 * kuzetsa shrugs
262 2013-11-08 01:08:27 <phantomcircuit> ryan-c, pretty sure that's pipe
263 2013-11-08 01:08:33 <ryan-c> maybe.
264 2013-11-08 01:08:36 <Evilmax> this is the error

266 2013-11-08 01:08:43 <Evilmax> what means?
267 2013-11-08 01:08:50 <kuzetsa> I've never tried to run ubuntu (as a desktop, server, development environment, or otherwise)
268 2013-11-08 01:09:05 <Evilmax> with sendfrom
269 2013-11-08 01:09:07 <kuzetsa> I'll take your word for it though that 5GB was enough O_O
270 2013-11-08 01:09:26 <ryan-c> kuzetsa: well, I just added an extra 0 to the existing 512MB in the config.
271 2013-11-08 01:09:49 <sipa> Evilmax: so, you're building a site that will be storing money, on a system you're not confortable with, avoiding trying to understand the security issues?
272 2013-11-08 01:09:53 <kuzetsa> "the config" <-- ooooh, ok, that ... wait, what?
273 2013-11-08 01:10:06 <phantomcircuit> sipa, shh it'll be hilarious
274 2013-11-08 01:10:27 <ryan-c> sipa: Yes, that seems to be what he's doing. I already tried telling him about how screwed his users will be.
275 2013-11-08 01:10:28 <Evilmax> please
276 2013-11-08 01:10:33 <Evilmax> just answer to question
277 2013-11-08 01:10:36 <Evilmax> if you know
278 2013-11-08 01:10:43 <kuzetsa> Evilmax: what question?
279 2013-11-08 01:11:02 <sipa> Evilmax: i know, but no; given these conditions i don't think it's wise to help you
280 2013-11-08 01:11:05 <Evilmax> you like to make judgments at random

282 2013-11-08 01:11:22 <Evilmax> question is: why sendfrom doesn't work
283 2013-11-08 01:11:25 <Evilmax> i get:

286 2013-11-08 01:11:36 <phantomcircuit> Evilmax, because you have no idea what you're doing

291 2013-11-08 01:11:55 <phantomcircuit> im fairly certain nobody here is going to help you in your endeavor since it's clearly a BadIdea(tm)
292 2013-11-08 01:12:01 <kuzetsa> Evilmax: you're using the syntax wrong... you need to somehow change the data type from string to something numeric
293 2013-11-08 01:12:18 <Evilmax> kuzetsa...the string i am using is:
294 2013-11-08 01:12:19 <michagogo> cloud!uid14316@wikia/Michagogo|Evilmax: 3.14, not "3.14"

310 2013-11-08 01:13:24 <Evilmax> i did not wrote "amount"

312 2013-11-08 01:13:29 <Evilmax> amount is just for example
313 2013-11-08 01:13:47 <sipa> yes, but it needs to be amount, not "amount"

330 2013-11-08 01:15:00 <Evilmax> ok

332 2013-11-08 01:15:09 <Evilmax> yes, i know
333 2013-11-08 01:15:09 <ryan-c> hey, what if one of your users is called ';rm --no-protect-root -rf /;#?
334 2013-11-08 01:15:17 <sipa> so you can directly send commands instead of forking a shell + curl to do so
335 2013-11-08 01:15:20 <Evilmax> tnx to an user of this chan
336 2013-11-08 01:15:30 <Evilmax> and how?

338 2013-11-08 01:16:00 <Evilmax> :)
339 2013-11-08 01:16:11 <sipa> have you thought about backups?
340 2013-11-08 01:16:14 <sipa> cold and hot wallets?
341 2013-11-08 01:16:19 <sipa> security?
342 2013-11-08 01:16:25 <sipa> legal protection?
343 2013-11-08 01:16:29 <Evilmax> again security?

345 2013-11-08 01:16:44 <Evilmax> then i will think abount security
346 2013-11-08 01:16:49 <ryan-c> <Evilmax> later i will think abount security

391 2013-11-08 01:22:32 <Evilmax> i want smoke
392 2013-11-08 01:22:48 <kuzetsa> you instead need this --> http://en.wikipedia.org/wiki/Integer_literal (except... well... a "real" datatype, rather than integer, but the idea is the same)
393 2013-11-08 01:22:53 <Evilmax> my girl...has gone away with another boy

403 2013-11-08 01:24:06 <warren> sipa: I suggested to the mastercoin people that they find a way to do most things offchain
404 2013-11-08 01:24:13 <kuzetsa> please take this discussion to #mudercoin-dev or something?
405 2013-11-08 01:24:32 <kuzetsa> it's rather off-topic for #bitcoin-dev :(
406 2013-11-08 01:24:33 <sipa> warren: don't think you're the first to do so
407 2013-11-08 01:24:36 <kuzetsa> and upsetting :(
408 2013-11-08 01:24:43 <Fistful_of_LTC> warren: is there a wallet you know of? for mastercoin?

411 2013-11-08 01:24:53 <warren> Fistful_of_LTC: mastercoin is a bad idea
412 2013-11-08 01:24:56 <sipa> Fistful_of_LTC: i hope not
413 2013-11-08 01:25:17 <Fistful_of_LTC> sipa: you guys don't think mastercoin is going to be succesful?
414 2013-11-08 01:25:24 <sipa> i hope not
415 2013-11-08 01:25:32 <pigeons> even if its sucessful it doesnt make it a good idea
416 2013-11-08 01:25:44 <Fistful_of_LTC> because it doesn't use bitcoins features where it should
417 2013-11-08 01:25:49 <Fistful_of_LTC> ?
418 2013-11-08 01:26:05 <Fistful_of_LTC> and it's on top of bitcoin instead of using bitcoin?
419 2013-11-08 01:26:14 <sipa> Fistful_of_LTC: as far as i understand it, it's a badly scaling system that abuses bitcoin as a storage mechanism
420 2013-11-08 01:26:24 CheckDavid has quit (Quit: Leaving)
421 2013-11-08 01:26:53 <Fistful_of_LTC> sipa: the way i see it it's just TCP to bitcoin's IP... with a bit more redundancy in the way it does things maybe
422 2013-11-08 01:27:38 <sipa> the features it adds are nice, but there's no way afaik to implement them efficiently
423 2013-11-08 01:27:43 <Fistful_of_LTC> but then ... is there a good way to do what it wants to do: decentralized markets? that is actually being developped right now?
424 2013-11-08 01:27:58 <sipa> and it remains abusive to do it on top of bitcoin, rather than say, a merged-mined own chain
425 2013-11-08 01:28:05 <firepacket> Linking bitcoin transactions to other bodys of information is essential. there has to be some small data storage allowed. I mean if you think about it, the whole thing is really data storage anyway
426 2013-11-08 01:28:13 <pigeons> Fistful_of_LTC: look at maaku and jtimon's hard-fork freimarkets for a workable implementation
427 2013-11-08 01:28:26 <sipa> firepacket: bitcoin is _not_ data storage
428 2013-11-08 01:28:36 <firepacket> sure it is
429 2013-11-08 01:28:52 <pigeons> even Alex Mizrahi's colored coins are more workable than this mastercoin stuff
430 2013-11-08 01:28:56 <sipa> firepacket: bitcoin is an incredibly expensive system, where you're forcing every full node to process all your data
431 2013-11-08 01:29:13 <warren> Fistful_of_LTC: would be much cheaper to put mastercoin in a low cost alt chain. Just don't be a parasite to bitcoin. don't care where else it goes.
432 2013-11-08 01:29:15 <Fistful_of_LTC> i like colored coins as well, but is that project actually evolving?
433 2013-11-08 01:29:18 <firepacket> the datastorage part (if labeled correctly) can be ignored by thin clients
434 2013-11-08 01:29:21 <warren> hmm, don't put it on litecoin's chain either
435 2013-11-08 01:29:24 <sipa> firepacket: these nodes choose to do so, because what they get is useful: a decentralized trustless worldwide electronic currency
436 2013-11-08 01:29:26 <Fistful_of_LTC> mastercoin's development strategy seems to be moving it forward
437 2013-11-08 01:29:44 <firepacket> it's that little bit of data storage that takes bitcoin's potential to the next level
438 2013-11-08 01:29:50 <firepacket> it doesn't have to be a lot
439 2013-11-08 01:29:52 <Fistful_of_LTC> (ie bounties heh.)
440 2013-11-08 01:30:04 <sipa> firepacket: if you're going to use bitcoin for other purposes, you are forcing them to do work which they aren't paid for
441 2013-11-08 01:30:09 <pigeons> firepacket: you can't have think clients with mastercoin, you need to index the entire btc blockchain to make sure you havent been doublemastercoin spent
442 2013-11-08 01:30:10 <ryan-c> is there a command to get the testnet chain height?
443 2013-11-08 01:30:11 <sipa> firepacket: and may not care about
444 2013-11-08 01:30:15 <Fistful_of_LTC> sipa: i agree with firepacket, although i also agree minimizing redundancy is essential
445 2013-11-08 01:30:17 <ryan-c> er, for the bot in the channel
446 2013-11-08 01:30:22 <maaku> Fistful_of_LTC: we have a distributed exchange, colored coin, and off-chain solution here : https://bitcointalk.org/index.php?topic=280292.0
447 2013-11-08 01:30:32 <firepacket> it's not really "other purposes" bitcoin is a timestamped transaction system
448 2013-11-08 01:30:40 <firepacket> providing information about the transaction is fully included in its purpose
449 2013-11-08 01:30:46 <sipa> firepacket: i fully disagree
450 2013-11-08 01:30:46 <firepacket> a little extra data stoage does just that

453 2013-11-08 01:31:09 <sipa> thankfully
454 2013-11-08 01:31:27 <sipa> bitcoin is a fight with scalability

457 2013-11-08 01:31:49 <firepacket> well we agree there
458 2013-11-08 01:32:01 <sipa> then don't put unnecessary data in it
459 2013-11-08 01:32:03 <ryan-c> his someone intenrionally issuing block exactly every 20 minutes?
460 2013-11-08 01:32:18 <Fistful_of_LTC> sipa: how do you think the available data space in bitcoin 0.9 will be and should be used?
461 2013-11-08 01:32:20 <firepacket> that depends on your definition of necesarry
462 2013-11-08 01:32:27 <maaku> if there wasn't a 25btc subsidy, no one would want to pay the real cost of putting data on the chain
463 2013-11-08 01:32:32 <sipa> Fistful_of_LTC: "available data space" ?
464 2013-11-08 01:32:45 <sipa> Fistful_of_LTC: ah, the OP_RETURN data
465 2013-11-08 01:32:53 <sipa> Fistful_of_LTC: i think it should not be used, but i know it will
466 2013-11-08 01:32:54 <Fistful_of_LTC> ya 8B arbitrary data
467 2013-11-08 01:33:00 <Fistful_of_LTC> lol
468 2013-11-08 01:33:25 <sipa> Fistful_of_LTC: it's there because not having it means people go put data elsewhere, where it hurts the system even more
469 2013-11-08 01:33:49 <sipa> it's really just a way to make abuse hurt less
470 2013-11-08 01:33:58 <firepacket> haha

473 2013-11-08 01:34:15 <firepacket> it's giving the people what they want and need so they don't abuse another feature to get it

475 2013-11-08 01:34:19 <firepacket> it's the smartest option
476 2013-11-08 01:34:30 <firepacket> but it's not "abuse"
477 2013-11-08 01:34:38 <Fistful_of_LTC> sipa: either way i like it ;)

480 2013-11-08 01:36:28 <Fistful_of_LTC> sipa: It seems to me it adds to bitcoin's flexibility, being able to use the existing blockchain (and therefore size), to add new features in a manner quite independant of it.
481 2013-11-08 01:36:59 <sipa> Fistful_of_LTC: being able to link transactions to additional data, in a committing way, is useful
482 2013-11-08 01:37:06 <Fistful_of_LTC> yes
483 2013-11-08 01:37:09 <sipa> putting data in it, much less
484 2013-11-08 01:37:11 <michagogo> cloud!uid14316@wikia/Michagogo|ryan-c: that's the testnet's 20-minute rule
485 2013-11-08 01:37:11 <Fistful_of_LTC> exactly
486 2013-11-08 01:37:16 <sipa> there are better ways to do so
487 2013-11-08 01:37:25 <Fistful_of_LTC> well you can link it
488 2013-11-08 01:37:26 <ryan-c> michagogo|cloud: ah, i see.
489 2013-11-08 01:37:31 <michagogo> cloud!uid14316@wikia/Michagogo|ryan-c: If 20 minutes go by without a testnet block, one block is allowed to be mined at difficulty 1
490 2013-11-08 01:37:42 <ryan-c> michagogo|cloud: yeah, i have the testnet wiki article up
491 2013-11-08 01:37:50 <michagogo> cloud!uid14316@wikia/Michagogo|Ah, cool
492 2013-11-08 01:38:05 <firepacket> how can you link a transaction to another body of data without including something in it?
493 2013-11-08 01:38:07 <ryan-c> Was the 20 minute rule a recent addition?
494 2013-11-08 01:38:30 <Fistful_of_LTC> sipa: how?
495 2013-11-08 01:38:36 <sipa> firepacket: that's actually possible, but it requires some crypto tricks
496 2013-11-08 01:38:38 <ryan-c> okay
497 2013-11-08 01:38:47 <ryan-c> that was added in 0.7

505 2013-11-08 01:39:30 <firepacket> oh
506 2013-11-08 01:39:44 <sipa> firepacket: i'm just worried that it is too easy, and will be abused to actually serve as data storage in the block chain

508 2013-11-08 01:40:00 <Fistful_of_LTC> like put a tinyurl, sign the content, have the hash in the OP_RETURN as well as the tinyurl.
509 2013-11-08 01:40:01 <sipa> (which is, compared to every other alternative, much better)

530 2013-11-08 01:44:39 <firepacket> thats what fees are for

539 2013-11-08 01:45:40 <firepacket> thats correct, but nobody is paying you to keep any of thsoe transactions on your disk
540 2013-11-08 01:45:53 <michagogo> cloud!uid14316@wikia/Michagogo|firepacket: Exactly
541 2013-11-08 01:45:55 <sipa> if it's mostly used to store other people's data, rather than build a currency, i'll likely stop running a node
542 2013-11-08 01:46:17 <Fistful_of_LTC> ah
543 2013-11-08 01:46:21 <sipa> if it becomes hard to run a node because of that, bitcoin isn't really decentralized anymore

557 2013-11-08 01:48:33 <sipa> if it's removed, i'm sure some people would fork the client to re-enable it

559 2013-11-08 01:48:55 <sipa> and as i said, it's better than the alternatives for data storage
560 2013-11-08 01:49:03 <firepacket> i guess i don't get the logic, if you're willing to store other people's transactions. why not store other people's transactional data?

568 2013-11-08 01:50:15 <sipa> firepacket: if bitcoin grows faster because people use it for pure data storage, which doesn't help its economy, the cost to benefits factor decreases
569 2013-11-08 01:50:22 <firepacket> it's true, full node maintenance needs to be accessible
570 2013-11-08 01:50:26 <Fistful_of_LTC> alright sina, i see your concern. But it seems to me even if you have other people's data, and even if the blockchain gets to what now seems like a ridiculous size, it may be negigible in the future. And the possibility to have data on it actually offsets the downside of size.
571 2013-11-08 01:51:26 <Zarutian> Fistful_of_LTC: I dont think the question is about storage capacity, more about bandwidth of shuttling the blocks around.
572 2013-11-08 01:51:34 <sipa> and verification
573 2013-11-08 01:51:46 <sipa> and latency degradation because of more data
574 2013-11-08 01:52:06 <sipa> and impact on the UTXO set (which OP_RETURN, compared to other alternatives, doesn't have)
575 2013-11-08 01:52:46 <firepacket> the issue is that the fees don't go to the nodes only the miners
576 2013-11-08 01:52:54 <firepacket> shitty
577 2013-11-08 01:52:55 <sipa> but the most important point is that for most cases (in particular mastercoin, as i understand it), there is no need to have that data in the block chain
578 2013-11-08 01:53:09 <Fistful_of_LTC> ah
579 2013-11-08 01:53:13 <sipa> it can be in a separate chain, merge-mined against bitcoin
580 2013-11-08 01:53:13 * Zarutian thought the defacto pattern for including extra data in tx was <extra data> OP_DROP <usual transfer code>
581 2013-11-08 01:53:17 <sipa> which has 0 cost to bitcoin
582 2013-11-08 01:53:38 <sipa> Zarutian: nope, the problem is that that data enters the UTXO set
583 2013-11-08 01:53:47 <sipa> with OP_RETURN transactions that's not the case
584 2013-11-08 01:54:56 robocoin has quit (Ping timeout: 246 seconds)
585 2013-11-08 01:55:32 <Zarutian> merge-mined? basicly, each block-chain regularly insert into each other a tx that link them to gether via prev-block hashes?
586 2013-11-08 01:55:35 <Fistful_of_LTC> could i make a bet with existing bitcoin transactions?
587 2013-11-08 01:56:51 <sipa> Fistful_of_LTC: not in the same way; i think there are some betting schemes possible in theory though
588 2013-11-08 01:56:52 robocoin has joined
589 2013-11-08 01:56:53 <Zarutian> sipa: so an extra TXO that doesnt recive any satoshis contains the extra data then?
590 2013-11-08 01:56:54 <firepacket> OP_RETURN makes the whole output unspendable?
591 2013-11-08 01:56:58 <sipa> firepacket: indeed
592 2013-11-08 01:57:05 <sipa> firepacket: _provably_ unspendable

595 2013-11-08 01:57:58 <Fistful_of_LTC> sipa: Mike hearn speaks of an 'oracle' that can verify if something happened, with smart properties i believe, is that possible right now?
596 2013-11-08 01:58:03 <firepacket> so for every spendable transaction to refrence you propose creating a second to reference the first?
597 2013-11-08 01:58:09 <sipa> Fistful_of_LTC: yes
598 2013-11-08 01:58:22 <Fistful_of_LTC> without adding a layer on top of bitcoin?
599 2013-11-08 01:58:26 <michagogo> cloud!uid14316@wikia/Michagogo|firepacket: Specifically, OP_RETURN *means* "make this output unspendable", so if it's the first byte of the scriptPubKey you, as a node, know that you don't need to remember that transaction
600 2013-11-08 01:58:48 <sipa> Fistful_of_LTC: yes

603 2013-11-08 01:59:15 <firepacket> But that does remove much of the utility of including extra data on a spendable transaction
604 2013-11-08 01:59:26 <sipa> firepacket: how so?
605 2013-11-08 01:59:40 <sipa> it's still in the block chain
606 2013-11-08 01:59:45 <sipa> and travels with the transaction
607 2013-11-08 01:59:51 <sipa> and the transaction provably commits to it
608 2013-11-08 01:59:53 <firepacket> the data doesn't get hashed and verified when the output moves?
609 2013-11-08 02:00:04 <sipa> yes it does
610 2013-11-08 02:00:15 <sipa> it just doesn't enter the database
611 2013-11-08 02:00:26 <sipa> of spendable outputs
612 2013-11-08 02:00:32 <firepacket> okay
613 2013-11-08 02:00:42 <sipa> (which is the most important thing to keep bitcoin block quickly verifiable)

617 2013-11-08 02:01:04 <sipa> michagogo|cloud: it's opt-in, yes
618 2013-11-08 02:01:16 <sipa> but i don't like where sf is going with that
619 2013-11-08 02:01:38 <firepacket> okay, if you use op_return how do you provably link that data with the transaction your refrencing?
620 2013-11-08 02:01:44 <ryan-c> is there a way to do 'bitcoind decoderawtransaction `bitcoind getrawtransaction <txid>`' in one command?
621 2013-11-08 02:01:51 <michagogo> cloud!uid14316@wikia/Michagogo|sipa: Yeah, neither do I
622 2013-11-08 02:01:58 <firepacket> it seems like you can use it to store data, but not to reference a transaction
623 2013-11-08 02:02:03 <michagogo> cloud!uid14316@wikia/Michagogo|ryan-c: `bitcoind getrawtransaction <txid> 1`
624 2013-11-08 02:02:23 <Zarutian> sipa, firepacket: the extra txout is part of the whole tx and because txin refers to the whole tx by hash and index tuple
625 2013-11-08 02:02:33 <michagogo> cloud!uid14316@wikia/Michagogo|sipa: Have you (pl) looked at Github's Releases feature they announced in July?

629 2013-11-08 02:04:24 <sipa> firepacket: you can put a transaction hash in there
630 2013-11-08 02:04:42 <firepacket> that just occured to me
631 2013-11-08 02:04:50 <imton> guys, which port should I open in the server to allow RPC remotely? in my client i am getting "Errno::ECONNREFUSED: Connection refused - connect(2)"

633 2013-11-08 02:05:03 <sipa> imton: 8332 by default

636 2013-11-08 02:05:35 <sipa> then that port
637 2013-11-08 02:05:37 <imton> how can i verify it is working?
638 2013-11-08 02:05:42 <michagogo> cloud!uid14316@wikia/Michagogo|imton: You'll need to set rpcallowip
639 2013-11-08 02:05:43 <Zarutian> side question: is there an unix domain socket option in bitcoind?
640 2013-11-08 02:05:48 <sipa> Zarutian: no
641 2013-11-08 02:05:52 <sipa> imton: connecting to it?
642 2013-11-08 02:06:05 <imton> yup
643 2013-11-08 02:06:06 <sipa> (which seems to be failing for you)
644 2013-11-08 02:06:08 <imton> rpcallowip
645 2013-11-08 02:06:11 <imton> ?
646 2013-11-08 02:06:14 <michagogo> cloud!uid14316@wikia/Michagogo|imton: By default it only accepts connections from localhost
647 2013-11-08 02:06:26 <imton> oh
648 2013-11-08 02:06:48 <michagogo> cloud!uid14316@wikia/Michagogo|add an rpcallowip line to the config file on the daemon with the remote IP address you want to allow
649 2013-11-08 02:06:53 <sipa> michagogo|cloud: if that was the problem, i think he'd get a different error
650 2013-11-08 02:06:57 <imton> well.. my ip is dynamic
651 2013-11-08 02:06:59 <ryan-c> Zarutian: You could use socat to make it available via a domain socket, but I'm guessing you want the socket so you can lock down the permissions.
652 2013-11-08 02:07:03 <michagogo> cloud!uid14316@wikia/Michagogo|Oh, would he?
653 2013-11-08 02:07:15 <Zarutian> ryan-c: exactly
654 2013-11-08 02:07:15 <firepacket> ok the only difference is that you wouldn't be able to find the extra data from a transaction. but you're right, mastercoin doesn't really need that ability
655 2013-11-08 02:07:35 <ryan-c> Zarutian: Would making it require TLS auth help you there?

658 2013-11-08 02:07:51 <firepacket> looking at a spendable transaction, you wouldn't know if there was extra data there without knowing where to look
659 2013-11-08 02:08:09 <sipa> firepacket: sure you would
660 2013-11-08 02:08:12 <firepacket> how?
661 2013-11-08 02:08:13 <sipa> firepacket: it's just be wasteful
662 2013-11-08 02:08:17 <sipa> it's just there...
663 2013-11-08 02:08:28 <Zarutian> firepacket: hence my suggestion of letting the external transaction data hash be something that can be stuck into an magnet: uri
664 2013-11-08 02:08:28 <sipa> whatever you put in a transaction script remains there
665 2013-11-08 02:08:39 <sipa> Zarutian: i don't see the point
666 2013-11-08 02:08:56 <ryan-c> Zarutian: actually, never mind, it doesn't appear to support listing with ssl
667 2013-11-08 02:09:16 <sipa> michagogo|cloud: you'd get http 403 if rpcallowip doesn't match

672 2013-11-08 02:10:16 <ryan-c> what, like cygwin?
673 2013-11-08 02:10:57 <Zarutian> sipa: allow the extra/external transaction data to be p2p transfered outside of bitcoin proto
674 2013-11-08 02:10:57 <sipa> firepacket: and OP_RETURN is not an unspendable transaction; it's makes a single output of a transaction unspendable

685 2013-11-08 02:11:59 <sipa> Zarutian: i mean that you rarely need linking to arbitrary data

727 2013-11-08 03:14:12 <dexX7> hello, is there a simple explaination for "TX rejected (code -22)" when sending a rawtx? this is the transaction in question: https://blockchain.info/tx/291860f4d2a247c44676dd8fdc1b1c17804aad25cdaf26e6c621ac6223608369^
728 2013-11-08 03:14:55 <CodeShark> if it's already in the mempool of bitcoind it will be rejected
729 2013-11-08 03:15:22 <CodeShark> since it's been relayed, it stands to reason your node has already seen it and has it in its mempool
730 2013-11-08 03:16:16 <CodeShark> in other words, bitcoind won't allow you to send the same transaction twice
731 2013-11-08 03:17:10 mrkent2 has quit (Ping timeout: 244 seconds)
732 2013-11-08 03:17:28 <dexX7> hmm.. it happend on the first try, i sent it then via blockchained.info pushtx
733 2013-11-08 03:18:28 <CodeShark> the other possibility is the fee
734 2013-11-08 03:18:37 <CodeShark> you have three outputs that are smaller than 0.01 btc
735 2013-11-08 03:18:46 <CodeShark> so it requires a relay fee
736 2013-11-08 03:19:19 <CodeShark> other than that the transaction looks totally standard
737 2013-11-08 03:19:56 <dexX7> i used a fee of 0.0002, the tx has a size of 506 byte
738 2013-11-08 03:21:15 <CodeShark> check your node's mempool
739 2013-11-08 03:21:21 <CodeShark> see if it has the transaction
740 2013-11-08 03:21:33 <CodeShark> before it gets confirmed, that is
741 2013-11-08 03:22:07 <CodeShark> if it's not there, then take a look at main.cpp - 711 GetMinFee

744 2013-11-08 03:25:12 <CodeShark> in the past I've added tracers to bitcoind to help me diagnose transaction errors
745 2013-11-08 03:25:37 <CodeShark> I'm thinking it might not be such a bad idea to at least add compile-time options for it

768 2013-11-08 03:51:16 <dexX7> that was intended, more or less. a similar tx with a slightly higher outgoing amounts and a fee of .0005 was smoothly accepted. thanks for your help. :)

810 2013-11-08 04:59:52 <dexX7> i found the source of problem. the dust threshold is actually 5460 satoshi instead of 5430.
811 2013-11-08 05:00:11 <BlueMatt> did you find the docs that disagreed with the source? :p
812 2013-11-08 05:00:18 <BlueMatt> gavinandresen: did that just to mess with people
813 2013-11-08 05:01:31 <dexX7> the post about 0.8.2 on the forums as well as https://github.com/bitcoin/bitcoin/pull/2577 mentiones 5430

819 2013-11-08 05:04:39 <gavinandresen> if you care about dust threshold 5460 instead of 5430, you're going to be really unhappy with changes I hope to get into the 0.9 release that will make the dust threshold float
820 2013-11-08 05:05:05 <gavinandresen> (float as in change as transaction fees go up/down, not float as in floating-point-format-variable)

826 2013-11-08 05:06:33 <BlueMatt> ^ that wasnt fun
827 2013-11-08 05:07:10 <CodeShark> gavinandresen
828 2013-11-08 05:07:25 <CodeShark> gavinandresen: have you written up something on the formula yet?
829 2013-11-08 05:08:10 <gavinandresen> BlueMatt: I'd have to page-swap Java knowledge back into my brain, and I think my swap partition is starting to fail
830 2013-11-08 05:08:24 <BlueMatt> gavinandresen: heh, well ok that could be a problem
831 2013-11-08 05:09:23 <gavinandresen> CodeShark: formula for dust will be the same as it ever was, it will just be calculated based on the 1%-median fee we've seen recently instead of hard-coded
832 2013-11-08 05:09:34 <gavinandresen> I think, I'm actually rebasing all that code right now....
833 2013-11-08 05:09:48 <CodeShark> by recently seen you're talking about the last n blocks?
834 2013-11-08 05:09:55 <CodeShark> last n blocks and mempool?
835 2013-11-08 05:10:18 <gavinandresen> CodeShark: last 10,000 transactions that were in the mempool and left the mempool by being accepted into a block, to be exact
836 2013-11-08 05:10:51 <gavinandresen> CodeShark: ⦠well, last 10,000 zero-priority, fee-paying if we're talking transaction fees
837 2013-11-08 05:11:05 <CodeShark> are you talking about a sort of moving average?
838 2013-11-08 05:11:12 <gavinandresen> (since we can't really reason about transactions with both priority and fee > 0)
839 2013-11-08 05:11:14 <BlueMatt> nice, relay nodes are seeing more spv checks (ie relays from nodes other than mine) instead of all block relays from my node
840 2013-11-08 05:11:37 <BlueMatt> y'all should keep peering :)
841 2013-11-08 05:12:19 <CodeShark> hmm, why 10,000?
842 2013-11-08 05:12:58 <CodeShark> and why not just use the block chain itself (to make, for instance, SPV client logic simpler)
843 2013-11-08 05:14:02 <gavinandresen> You're right, I'll make it 11,000, that is a better number.
844 2013-11-08 05:14:06 <CodeShark> lol
845 2013-11-08 05:14:35 <gavinandresen> I do have a write-up somewhere that talks about the SPV issue....
846 2013-11-08 05:14:43 <CodeShark> perhaps we should run a few simulations with different n to see what happens

851 2013-11-08 05:16:17 <gavinandresen> CodeShark: knock yourself out. During development, I kept track of estimated fees/priority after various numbers, estimates need a minimum of 100 transactions, 10,000 seems like a reasonable number to keep around
852 2013-11-08 05:16:29 <gavinandresen> CodeShark: https://gist.github.com/gavinandresen/6548612

854 2013-11-08 05:16:43 <BlueMatt> essentially
855 2013-11-08 05:17:02 <BlueMatt> as the person who will end up writing the bitcoinj client-side fee code, I prefer we dont use blocks :)
856 2013-11-08 05:17:30 <CodeShark> perhaps the simplest SPV client logic of all is to just start at 0, try to send - if it fails, raise it small increments until it succeeds
857 2013-11-08 05:18:17 KillYourTV has joined
858 2013-11-08 05:19:05 <CodeShark> or set the minimum based on some hardcoded constants - and then raise incrementally until success

860 2013-11-08 05:20:43 <CodeShark> a slightly more complex approach is to use a random sampling
861 2013-11-08 05:20:57 <BlueMatt> ewwwwww
862 2013-11-08 05:21:04 <BlueMatt> better to ask someone
863 2013-11-08 05:21:31 <CodeShark> you mean add a "getfee" message to the p2p protocol?
864 2013-11-08 05:21:59 <gavinandresen> user experience with any "I'll just re-send the transaction" is awful, especially if the keys are encrypted, and especially on a device like a phone that only connects to catch up and send.

866 2013-11-08 05:22:54 <CodeShark> gavinandresen: multiple transactions with the corresponding fees could be signed at the same time
867 2013-11-08 05:22:59 <gavinandresen> (pre-signing a bunch of variations of the transaction "just in case we need more fees" doesn't work either)
868 2013-11-08 05:23:07 <CodeShark> and then the sending could be done in the background without requiring the key
869 2013-11-08 05:23:18 <gavinandresen> ⦠because you'll just end up locking inputs that the user might want to spend, and that sucks

879 2013-11-08 05:24:48 <gavinandresen> you've got two inputs in your wallet: 1BTC and 50BTC. Now you send 1BTC. What happens?
880 2013-11-08 05:24:53 <BlueMatt> what about hardware wallets...
881 2013-11-08 05:25:03 <BlueMatt> really, you have to ask someone
882 2013-11-08 05:25:05 <BlueMatt> p2p or otherwise

888 2013-11-08 05:26:39 <CodeShark> it does add a small cost of an extra input in the case that no fee is required

891 2013-11-08 05:27:25 <gavinandresen> CodeShark: right, so 49.something BTC are locked up and cannot be spent for some amount of time because you don't know WHICH change output will end up being used
892 2013-11-08 05:27:31 <BlueMatt> just go look at the code fragment I linked above in bitcoinj's wallet
893 2013-11-08 05:27:34 <gavinandresen> That sucks as a user experience
894 2013-11-08 05:27:42 <BlueMatt> its /ugly/
895 2013-11-08 05:27:54 <CodeShark> signing txn can get very expensive?!?!? it takes milliseconds on typical hardware
896 2013-11-08 05:28:07 <CodeShark> I've even managed to sign on an 8 bit processor in a few seconds :p

921 2013-11-08 05:44:39 <BlueMatt> CodeShark: yea, Ive written a highly-optimized secp256k1 impl in java before
922 2013-11-08 05:44:47 <BlueMatt> with like 10 different versions with/without tables
923 2013-11-08 05:44:51 <BlueMatt> and different multiplication methods
924 2013-11-08 05:45:06 <BlueMatt> and they were all slow as fuck, so I gave up and implemented jni bindings for sipa's secp256k1 library
925 2013-11-08 05:45:20 <CodeShark> well, of course you're not going to beat natively-compiled C
926 2013-11-08 05:45:21 <BlueMatt> well, faster than bouncycastle by a lot, but waay slower than native
927 2013-11-08 05:45:52 <CodeShark> in any case, the important optimization application for sipa's library is verification, not signing
928 2013-11-08 05:46:02 <CodeShark> for verification it can make a HUGE difference
929 2013-11-08 05:46:06 <BlueMatt> yes, but its not slow at signing ;)
930 2013-11-08 05:46:49 <CodeShark> right - point is, signing is less resource-intensive inherently and is done much less frequently (at least in terms of real-world bitcoin applications)
931 2013-11-08 05:47:40 <CodeShark> and unless you're using an extremely slow processor performance is probably not a significant issue

948 2013-11-08 06:08:47 <CodeShark> I'm also thinking that the "evil miner" issue might be somewhat mitigated by removing outlier transactions from blocks in the calculation
949 2013-11-08 06:10:07 <CodeShark> if the mean of fees for transactions in the last n blocks is 0.0005 but a bunch of transactions also have fees that are much higher, you exclude those

963 2013-11-08 06:19:41 <Luke-Jr> could easily stick a pubkeyhash in blocks the miner can use to sign policy broadcast scripts with
964 2013-11-08 06:19:43 <CodeShark> Luke-Jr: there are two separate issues here - miner fee policy and relay policy
965 2013-11-08 06:19:49 <Luke-Jr> true
966 2013-11-08 06:19:59 <Luke-Jr> relay trial and error is pretty simple though

968 2013-11-08 06:20:10 <Luke-Jr> retry every minute until it comes back
969 2013-11-08 06:21:35 <CodeShark> would be nice if the protocol allowed fees paid for relay and not just mining :)

971 2013-11-08 06:22:47 <CodeShark> there are only at best highly indirect economic incentives for full nodes to accept SPV client connections
972 2013-11-08 06:23:27 <Luke-Jr> trivial to add a "pay to use" to the protocol :P

977 2013-11-08 06:29:33 <CodeShark> it would be wonderful to separate the two fee types completely
978 2013-11-08 06:29:54 <CodeShark> then a relay node can set its own relay policy just as arbitrarily as a miner can
979 2013-11-08 06:30:46 <CodeShark> it would create incentives to set up dedicated relay servers for thin clients
980 2013-11-08 06:31:17 <CodeShark> while still maintaining decentralization
981 2013-11-08 06:32:00 <CodeShark> furthermore, it doesn't really make economic sense for the relay nodes to be defining their policy based on what miners accept
982 2013-11-08 06:32:34 digitalmagus2 has quit (Ping timeout: 260 seconds)
983 2013-11-08 06:32:52 <CodeShark> a relay node cares about its own resource utilization primarily - and the speed/efficiency of the network as a whole secondarily
984 2013-11-08 06:33:03 <imton> how'd the protocol force senders to pay to the relay-er?
985 2013-11-08 06:33:51 <CodeShark> the relayer could require an output they provide to be in the transaction
986 2013-11-08 06:34:24 <CodeShark> however, this only seems to make sense if the relayer is directly connected to the miners
987 2013-11-08 06:34:55 <CodeShark> once you're more than two steps removed it gets much more complicated
988 2013-11-08 06:35:03 <Eneerge> any of you done much firefox addon development? Anyone know how to detect when one of the firefox error pages is shown. EG: no cipher overlap, 404 errors, etc. I think those are chrome pages.... I have it intercepting all connections before they occur and I can get the response if the connection was successful, but if any chrome page loads, no event is thrown that i'm aware of

990 2013-11-08 06:36:23 <imton> why does it only makes sense if the relayer is directly connected to the miners only?
991 2013-11-08 06:36:39 <CodeShark> if you require an additional hop, how does that node get paid?
992 2013-11-08 06:36:45 arioBarzan has joined
993 2013-11-08 06:37:07 <CodeShark> if a transaction takes multiple paths to the miner, each version will also be different
994 2013-11-08 06:37:43 <imton> right
995 2013-11-08 06:37:50 <imton> we always want the shortest path
996 2013-11-08 06:37:58 <CodeShark> I suppose you could pay a relay node up front to process so many messages or whatever

998 2013-11-08 06:38:32 <CodeShark> hub nodes could get wholesale pricing or even free direct connections to miners
999 2013-11-08 06:39:07 <CodeShark> but then you need proof that the node actually relayed the transaction
1000 2013-11-08 06:39:21 <CodeShark> and to what peers - etc...

1005 2013-11-08 06:44:12 <CodeShark> and all these things can be negotiated over some higher level protocol

1088 2013-11-08 08:50:54 <shripadk> if i send to two multisig addresses (one is 2-of-3 and the other 2-of-2) in a single transaction, can the amount be redeemed? does the limit of 520 byte scriptPubKey and 500 byte scriptSigs cause any problems?

1094 2013-11-08 08:55:47 <shripadk> also while redeeming the amount, how do i decide the amount of fee that needs to be included? the only input is the multisig address (via txid + scriptPubKey + redeemScript) and the only output will be the recipient address. will it always be 0.0001btc even for large amounts?

1101 2013-11-08 09:01:16 <sipa> ok
1102 2013-11-08 09:01:41 <sipa> so just use listtransactions, and see if you see any new receives since the previous call

1107 2013-11-08 09:02:09 <imton> should I use 1 account only?
1108 2013-11-08 09:02:19 <sipa> forget about accounts
1109 2013-11-08 09:02:48 <sipa> they're only useful if you'd do all handling inside bitcoin
1110 2013-11-08 09:02:59 <sipa> and have many issues in that case
1111 2013-11-08 09:03:01 <imton> oh, I see , you want me to use this " If [account] not provided will return recent transaction from all accounts."
1112 2013-11-08 09:03:06 <imton> right?
1113 2013-11-08 09:03:28 <sipa> you can specify account "*" explicitly
1114 2013-11-08 09:03:54 <sipa> which means everything
1115 2013-11-08 09:03:54 <HaltingState> my hardware bitcoin wallet is going to be laser cut anodized aluminum; this is going to look awesome http://i.imgur.com/eUDL3oQ.jpg
1116 2013-11-08 09:04:07 <imton> sipa: great. And do i see both received and spent transactions with listtransactions right?
1117 2013-11-08 09:04:33 <sipa> imton: you shouldn't care about spends imho
1118 2013-11-08 09:04:47 <sipa> imton: you know when you're sending coins, no?
1119 2013-11-08 09:05:06 <imton> sipa: I should. Yes.
1120 2013-11-08 09:05:30 <imton> sipa: but I want to know if I can rely on "listtransactions" for everything related to addresses
1121 2013-11-08 09:05:30 <sipa> this is for a cold/hot wallet solution, right?
1122 2013-11-08 09:06:08 <sipa> or for a system where the wallet is not yours?
1123 2013-11-08 09:06:25 <imton> sipa: cold/hot wallet
1124 2013-11-08 09:06:40 <imton> well.. no, sorry.

1129 2013-11-08 09:07:25 <sipa> i mean, who has the actual private keys

1131 2013-11-08 09:07:51 <imton> Well right now we do, but I am rethinking it to they
1132 2013-11-08 09:08:06 <imton> so they are encrypted locally (kind of blockchain wallet)
1133 2013-11-08 09:08:23 xiangfu has joined
1134 2013-11-08 09:08:25 <imton> it's not lunched yet so, i have time to do it right

1136 2013-11-08 09:09:09 <sipa> so, listtransactions will report both sends and receives
1137 2013-11-08 09:09:44 <sipa> but if the spends are from a waller you don't control, you can't rely on sends being interpreted correctly
1138 2013-11-08 09:09:49 <imton> I just don't want to rely on blockchain.info webapi service, I want to host my own blockchain locally
1139 2013-11-08 09:10:40 <sipa> if you just need the balance of someone's wallet, you can tally up receives minus sends of course
1140 2013-11-08 09:11:09 <sipa> though in that case it may actually make sense to use the accounts system, and use an account per user
1141 2013-11-08 09:11:19 <imton> sipa: in the case another wallet i don't control spends the same txout, will I see it with listtransactions?
1142 2013-11-08 09:11:39 <imton> sipa: yes, 1 account for each user may be a little more organized.
1143 2013-11-08 09:11:40 <sipa> yes
1144 2013-11-08 09:11:52 <imton> sipa: great
1145 2013-11-08 09:12:07 <sipa> but you are aware that you'll need to know about the user's wallet
1146 2013-11-08 09:12:19 <imton> yes
1147 2013-11-08 09:12:22 <sipa> every time a new key gets used, you'll need to know it in advance
1148 2013-11-08 09:12:44 <imton> oh, you are right
1149 2013-11-08 09:12:52 <sipa> which really requires deterministic wallets to do right
1150 2013-11-08 09:13:37 <imton> ok, then I think the most similar thing to searchrawtransactions would be using one account only
1151 2013-11-08 09:14:00 <sipa> this is independent from how you implement things
1152 2013-11-08 09:14:17 <sipa> you need to know of every key in the wallet before it gets used
1153 2013-11-08 09:15:49 <imton> great
1154 2013-11-08 09:15:54 <sipa> which works if it's your own wallet of course
1155 2013-11-08 09:16:09 <sipa> but i don't see how you'd do it for other people's wallets
1156 2013-11-08 09:16:19 <sipa> without deterministic wallets
1157 2013-11-08 09:17:07 <imton> I am reading about deterministic wallets
1158 2013-11-08 09:17:15 <imton> never heard of them before
1159 2013-11-08 09:17:26 <sipa> it's just about this problem
1160 2013-11-08 09:17:35 <sipa> every time a user does a transaction
1161 2013-11-08 09:17:49 <sipa> change goes to a new freshly-generated address of his
1162 2013-11-08 09:18:01 <sipa> you need to know about this change address in advance
1163 2013-11-08 09:18:40 <sipa> because otherwise you cannot know that this is a send-to-self output, rather than coins that left the wallet
1164 2013-11-08 09:19:08 <imton> but I can generate a new address at the time a tx is made for the change, right?
1165 2013-11-08 09:19:22 <imton> or use one from a pool of pre-generated
1166 2013-11-08 09:19:22 <sipa> if it is your wallet, sure
1167 2013-11-08 09:19:48 <imton> I don't get what is the problem if it is other people's wallet...
1168 2013-11-08 09:20:06 <sipa> you cannot know an address that they don't have yet
1169 2013-11-08 09:20:30 <imton> oh, but my system will be generating a new one for them
1170 2013-11-08 09:20:42 <imton> or use one pre-generated just for them

1176 2013-11-08 09:21:37 <imton> as an any exchange do...
1177 2013-11-08 09:21:42 <imton> ?
1178 2013-11-08 09:22:00 <imton> or they can be generated locally in their browser (by js)
1179 2013-11-08 09:22:16 <sipa> oh
1180 2013-11-08 09:22:32 <sipa> so it's still a wallet under your control
1181 2013-11-08 09:22:44 <sipa> not an arbitrary wallet controlled by the user
1182 2013-11-08 09:23:26 <sipa> i'm no fan of systems that claim to do things client-side
1183 2013-11-08 09:23:44 <sipa> but it seems tp work marketing-wise :(

1203 2013-11-08 09:36:40 <imton> sipa: isn't client side (js) under my control if the wallet (i.e. JSON) is entrypted under user password/passphrase?

1205 2013-11-08 09:37:11 <imton> adam3us: use case is an exchange service
1206 2013-11-08 09:37:34 <adam3us> imton: you want to think about type2 exchange like bitalo claims to be working on
1207 2013-11-08 09:37:57 <adam3us> imton: then the exchange doesnt have the bitcoin ownership
1208 2013-11-08 09:38:08 <imton> adam3us: but in my service, the exchange will be done between people directly.
1209 2013-11-08 09:38:22 <adam3us> imton: ok even a type3 exchange :) even better
1210 2013-11-08 09:38:51 <adam3us> imton: relying on atomic swap protocol?
1211 2013-11-08 09:39:01 <imton> adam3us : where can I find more info about that "bitalo" ?

1215 2013-11-08 09:39:37 <imton> we are more like an escrow
1216 2013-11-08 09:40:47 <adam3us> ye are you escrowing the usd?
1217 2013-11-08 09:41:44 <imton> nop. btcs
1218 2013-11-08 09:41:59 <imton> we'd need to own the btcs then, yes.
1219 2013-11-08 09:42:08 <imton> the "sellers" btcs
1220 2013-11-08 09:42:44 <adam3us> imton: i dont think you need to own them, just get them paid into a 2 of 2 multisig address that the user holds one key and you hold the other
1221 2013-11-08 09:43:07 <adam3us> imton: thats what i mean type2 like bitalo
1222 2013-11-08 09:43:33 <imton> well.. I though about that
1223 2013-11-08 09:44:23 <adam3us> imton: but i dont think it stops the cheating, how is the buyer paying? by any means like bitcoin-otc? then buyer will claim they paid and seller will claim they didnt, or tht payment was for something unrelated, and you cant tell who is lying

1229 2013-11-08 09:47:24 <imton> awesome, will read that!
1230 2013-11-08 09:47:43 <imton> adam3us I was thinking about the 2of 2 multisig but I can't remember something I couldn't understand
1231 2013-11-08 09:47:45 <adam3us> imton: yes but trust sucks; and irrevocable ecash / digital bearer certificates are the worst case scenario
1232 2013-11-08 09:49:05 <adam3us> imton: perfect crime scenario, its like buying bitcoin with credit-cards you basically cant do it, squishy, weak, revocable, insecure system plus reputation meets cold hard irrevocable ecash - squishy system loses fast
1233 2013-11-08 09:49:21 <TD> you *can* do it
1234 2013-11-08 09:49:24 <TD> it just requires extreme care
1235 2013-11-08 09:49:27 <TD> and amazing business deals
1236 2013-11-08 09:49:34 <TD> and that you have a video of someone at visa or mastercard snorting coke
1237 2013-11-08 09:49:49 <adam3us> imton: as good as it gets is probably like bitcoin-otc that has reputation based on pgp signature web of trust
1238 2013-11-08 09:50:37 <imton> adam3us: I get what you say, but I think if I want to make a service my friends and mom can use, PGP and lot of encryption info doesn't work with them

1242 2013-11-08 09:51:43 <imton> adam3us: sure, "1234" password won't be allowed :p

1246 2013-11-08 09:53:14 <imton> well.. I think one big part of any service trying to simplify bitcoins if to train and educate they users
1247 2013-11-08 09:53:38 <imton> but I can't ask them for everything at day 1.
1248 2013-11-08 09:54:50 <imton> adam3us: thanks for that link too
1249 2013-11-08 09:55:48 <imton> ama3us: about the multi sign tx you said.. The problem I was thinking was that the seller needs to know to witch user to send it..right?
1250 2013-11-08 09:55:50 <Happzz> is it reasonable that the testnet blockchain is like around the 300mb only?
1251 2013-11-08 09:56:53 <imton> adamus: but if the seller doesn't know who will be selling to because they just want to place the selling order.... how can he use multisign to then send the tx instantly at the order-matched time?
1252 2013-11-08 10:02:10 <imton> Happzz: yes

1355 2013-11-08 12:52:44 <sipa> xeroc: p2sh is just a way of moving the actual script from the output to the input
1356 2013-11-08 12:52:56 <sipa> what you put inside can be a multisig script, but doesn't have to be
1357 2013-11-08 12:53:40 <sipa> it has the advantage that the sender does not need to know (or care) what the actual script it (it's the receiver's business what he does with it)
1358 2013-11-08 12:53:52 <sipa> and putting less data in the UTXO set, which is critical for performance
1359 2013-11-08 12:53:53 <xeroc> ahh ..
1360 2013-11-08 12:54:13 <xeroc> now I even understand whats stated in the abstract of the bip ...

1382 2013-11-08 13:18:33 <sipa> 243 * 1.024 ~ 250 ?
1383 2013-11-08 13:18:55 <TD> adam3us: basically the majority of miners still need babysitting by the developers. they don't have the tools to really get insight into the consequences of their chosen configurations, and they get the inflation, so why change things?
1384 2013-11-08 13:19:05 <TD> sipa: oh right, yeah, 1000 vs 1024 confusion in the code could be it
1385 2013-11-08 13:19:21 <TD> adam3us: i keep meaning to submit a pull req that defaults the soft limit to the hard limit
1386 2013-11-08 13:19:29 <sipa> iirc inside bitcoind all constants/calculations use 1000-based kilobytes
1387 2013-11-08 13:20:04 <TD> also i'd like to write a patch that when receiving a block, shows the fees that *could* have been claimed, but weren't
1388 2013-11-08 13:20:11 <TD> so miners can see what they're missing out on

1494 2013-11-08 15:01:52 <dobry-den> pure was the wrong word. I'm weaning my client off Bouncy Castle and Java's nebulous crypto interface.
1495 2013-11-08 15:02:39 <TD> it's better to just JNI to libsecp256k1 i think
1496 2013-11-08 15:02:59 <TD> as you observe, bouncy castle is already just java by itself.
1497 2013-11-08 15:03:03 <TD> we need less purity :)
1498 2013-11-08 15:03:46 <dobry-den> Hah, right. By "pure" I meant "untainted by nebulous APIs".
1499 2013-11-08 15:04:14 <Zarutian> HaltingSate: I would recommend that you add an protosheild between the 'duino and the keypad sheild so you can add extra flashchips that can be accessed via spi.

1573 2013-11-08 15:43:14 <imton> oh...
1574 2013-11-08 15:43:34 <sipa> if you regularly need it, you're doing something wrong
1575 2013-11-08 15:43:46 <imton> yeah i know.
1576 2013-11-08 15:43:55 <sipa> it's mostly for emergency backup
1577 2013-11-08 15:43:59 <sipa> recovery
1578 2013-11-08 15:44:18 <sipa> in normal cases, you import an address before using it
1579 2013-11-08 15:44:19 <imton> I may have to pre-generate address and add that pool
1580 2013-11-08 15:44:25 reneg has joined
1581 2013-11-08 15:44:25 <imton> but I don't want to pre-generate
1582 2013-11-08 15:44:34 <sipa> why not?
1583 2013-11-08 15:44:44 <thermoman> we experience hughe delay for tx to be known in the network
1584 2013-11-08 15:44:56 <imton> sipa: because that way I will be owning the priv keys
1585 2013-11-08 15:45:02 <thermoman> some are delayed for a long time, some are on the network instantly

1588 2013-11-08 15:45:49 <sipa> imton: bip32 allows deriving addressesbwithout knowing the private key

1594 2013-11-08 15:46:39 <sipa> imton: if you don't reacan, no
1595 2013-11-08 15:46:57 <imton> sipa: if I don't rescan that means I can not look to past txs right?
1596 2013-11-08 15:47:03 <sipa> indeed
1597 2013-11-08 15:47:09 <imton> sipa: but that should be ok if the address is new
1598 2013-11-08 15:47:10 <sipa> so import an address before using it
1599 2013-11-08 15:47:53 <imton> sipa: why do you consider client-side js wallets a false sense of security?
1600 2013-11-08 15:48:37 <sipa> imton: if your server gets hacked, the coins can still be stolen
1601 2013-11-08 15:48:52 <sipa> by injecting malicious code in the site
1602 2013-11-08 15:49:07 <imton> well... that can happen everywhere
1603 2013-11-08 15:49:08 <sipa> or if you turn evil, youcan steal
1604 2013-11-08 15:49:16 <imton> if bitcoin binaries server are hacked too
1605 2013-11-08 15:49:20 <sipa> of course
1606 2013-11-08 15:49:28 <sipa> but i'd rather be honest about it
1607 2013-11-08 15:49:47 <sipa> client-side js wallets give a feeling of security
1608 2013-11-08 15:49:51 <imton> I plan to be as honest as possible yes
1609 2013-11-08 15:50:02 <sipa> but they don't provide much
1610 2013-11-08 15:50:03 <t7> maybe when browsers have a way to freeze js files
1611 2013-11-08 15:50:04 <imton> but I get what you mean
1612 2013-11-08 15:50:08 <t7> even then i am scared

1616 2013-11-08 15:50:42 <sipa> but not when they try to claim they are secure
1617 2013-11-08 15:50:51 <sipa> through such measures
1618 2013-11-08 15:50:58 <TD> sipa only uses web wallets that claim to be riddled with bugs and gaping security holes
1619 2013-11-08 15:51:04 <sipa> no
1620 2013-11-08 15:51:04 <TD> that's how he knows they're honest and trustworthy

1624 2013-11-08 15:51:39 <imton> i do
1625 2013-11-08 15:51:41 <lianj> i guess he mean if they only point to one layer of security and say because of that its secure
1626 2013-11-08 15:51:52 <Ry4an> I don't use web-wallets but if I did my firm requirement would be the person running it needs to have the domain registered with their real name.

1632 2013-11-08 15:53:16 <sipa> better be clear about that, no reason to make it seem more secure

1634 2013-11-08 15:54:55 <lianj> 2fa login is also one of those false sense for security in most cases
1635 2013-11-08 15:55:18 <sipa> 2fa is useful, but onlt as log as you trust the provider
1636 2013-11-08 15:55:47 <Ry4an> 2fa makes it harder for malware on _your_ computer to access the site and writhdraw your funds. It definitely doesn't protect you against the site owner.

For example gox (and beleive me I'm not holding htem as a great example for most things :) let you require your 2fa code for each transfer, so a xss attack can't do a 2nd transfer to their account just because you've already used your 2fa to login.

1688 2013-11-08 16:39:14 <gulli> so I turned armory off, turned bitcoind on
1689 2013-11-08 16:39:28 <gulli> bitcoind downloaded the last 15 hours of the chain
1690 2013-11-08 16:39:42 <gulli> turned it off and armory back online and there it was, now usable
1691 2013-11-08 16:39:47 <dexX7> ah
1692 2013-11-08 16:40:03 <gulli> armory uses bitcoind though, so I don't know why it isnt downloading the chain

1739 2013-11-08 17:31:22 <iceTwy> Debian only provides packages for libdb5.1, yet bitcoin must use libdb4.8 to compile
1740 2013-11-08 17:31:34 <iceTwy> so, watdo
1741 2013-11-08 17:31:38 <jaakkos> iceTwy: have you checked unstable and experimental

1748 2013-11-08 17:35:46 <jaakkos> iceTwy: i checked archive.debian.net but no luck... the closest match is 4.6 in lenny
1749 2013-11-08 17:35:51 <wumpus> iceTwy: depends on what you want, if you don't care about compatibility with pre-compiled bitcoins you can use 5.1

1751 2013-11-08 17:36:39 <wumpus> iceTwy: and it's always possible to convert back to 4.8 compatible wallet using a script
1752 2013-11-08 17:36:41 <helo> you should be able to downgrade your wallet from 5.1 if you need to run it in a standard libdb4.8 bitcoind
1753 2013-11-08 17:36:54 <iceTwy> well here's the thing
1754 2013-11-08 17:37:02 <iceTwy> I'm only installing Bitcoin to run coinpunk, in this case
1755 2013-11-08 17:37:06 <iceTwy> so yeah
1756 2013-11-08 17:37:12 <wumpus> just built it against bdb 5.1
1757 2013-11-08 17:37:33 <iceTwy> alrighty
1758 2013-11-08 17:38:03 <wumpus> coinpunk only uses watch only wallets anyway
1759 2013-11-08 17:38:19 <wumpus> which are not compatible with any of the prebuilt bitcoins
1760 2013-11-08 17:38:25 <iceTwy> oh, okay

1781 2013-11-08 17:50:09 <imton> guys, question. Is there a way to archive the following. A service that allows a seller of BTCs to another untrusted person, the service should be able to verify (and decide dispute) but not own the btcs. I think this is solved by multi sign txs. *But* what if the seller want to place that order in an order book for a future limit order, so at the time of placing the order he does not know which is the buyer so he doesnâ
1782 2013-11-08 17:50:10 <imton> buyers address. Can this be automated by the service without owing the btcs?

1823 2013-11-08 18:26:26 <adam3us> imton: so the seller pays the bitcoins to a 2 of 2 address with 1 address controlled by the exchange
1824 2013-11-08 18:26:30 <imton> adam3us: I rephrased it just in case
1825 2013-11-08 18:26:51 <adam3us> imton: then the seller advertises his order
1826 2013-11-08 18:26:57 <adam3us> imton: the exchnge helps him find a buyer

1830 2013-11-08 18:27:31 <adam3us> imton: user makes a transaction from himself to the buyer

1832 2013-11-08 18:28:16 <adam3us> imton: exchange checks whatever it wants (eg that funds are moved, reputation checks out etc) and signs the second sig, optionally from a green address to make settlement faster
1833 2013-11-08 18:28:35 <adam3us> imton: i think that is what bitalo is doing
1834 2013-11-08 18:29:39 <adam3us> imton: finally you can also timelock so that the seller gets full control of his coin back after eg 24hr, in case the exchange goes bankrupt or tries to extort the user
1835 2013-11-08 18:29:52 <imton> ok

1852 2013-11-08 18:34:13 <adam3us> imton: both the user and the exchange must approve the transaction, in that way the exchange can not steal user coins; thats the type2 exchange idea bitalo are using
1853 2013-11-08 18:35:43 <imton> when does the seller know of the buyer's address?
1854 2013-11-08 18:35:48 <imton> (seller of the btcs)
1855 2013-11-08 18:35:49 MC1984 has quit (Ping timeout: 244 seconds)
1856 2013-11-08 18:36:04 <adam3us> imton: whenever the buyer accepts the offer
1857 2013-11-08 18:36:35 <imton> and then can the exchange automate that process or need to ask the seller for something, if so , what?
1858 2013-11-08 18:36:50 <adam3us> imton: the buyer's address would have to be communicated somehow eg direct between the buyer/seller, via p2p, or via the exchange
1859 2013-11-08 18:37:09 <adam3us> imton: the seller is passive, he's just receiving funds, you dont even need to be online to do that
1860 2013-11-08 18:37:42 Coincidental has joined
1861 2013-11-08 18:37:49 <imton> yeah, it's only relyed to the network at the end I think
1862 2013-11-08 18:37:51 <adam3us> imton: you can even pay funds over an airgap (ie the private key doesnt need to be online, only for the sender to knwo the recipients public key (or more accurately the recipients address))
1863 2013-11-08 18:38:30 <imton> yes. So I think I still missing a part of the 2of2 multi sign flow

1868 2013-11-08 18:40:29 <imton> adam3us: because I didn't find anything related to 2of2, there is a lot of information about 2of3

1873 2013-11-08 18:41:38 <adam3us> imton: it just like a bank mandate you are instructing any relying party that two signatures are both needed for this cheque
1874 2013-11-08 18:41:47 <helo> it's just a way to lock up the coins being sold until the buyer's address is known
1875 2013-11-08 18:42:18 <adam3us> helo: right, you are delegating shared authority to the exchange, so the buyer can be assured the seller cant backout
1876 2013-11-08 18:42:21 <helo> the seller could refuse to sign the transfer to the buyer to get his coin back, though
1877 2013-11-08 18:42:33 <helo> (assuming there is an automatic 24-hour refund)
1878 2013-11-08 18:42:51 <adam3us> helo: sure, but you can click cancel on limit orders on gox exchange etc

1880 2013-11-08 18:43:44 <adam3us> helo, imton: we're presuming the seller wants to sell at the advertised price, and if he changes his mind (eg the price goes up) he can cancel and create a new sell order (or similar if its lower an so no one wll accept such a high sell now)
1881 2013-11-08 18:43:56 <ryan-c> I was asking earlier about setting up something that allows for either a signature from a master key or N-of-M from some other set of keys. It looked to me like there's not currently a good way to do it - though N-of-M or master can be done by N+N-of-M+N where the master key is used multiple times. But that gets big.

1883 2013-11-08 18:44:23 <helo> you can't really tie the transfer of bitcoin to the transfer of a physical asset without an escrow (trusted exchange)
1884 2013-11-08 18:44:41 <gmaxwell> ryan-c: luke has a proposed script for that kind of usage.
1885 2013-11-08 18:44:57 <adam3us> ryan-c: i think you could do that also with a script sig (you can basically write a mini program to accept on whatever conditions you want)
1886 2013-11-08 18:45:00 <ryan-c> gmaxwell: I was looking through BIPs this morning, is there one?
1887 2013-11-08 18:45:08 <helo> with colored coin things get kind of interesting, but fiat-backed-colored-coin is a ways off :)
1888 2013-11-08 18:45:19 <adam3us> gmaxwell: cant you achieve that with a script directly
1889 2013-11-08 18:45:49 <ryan-c> adam3us: Well, so say I want either the master key or 5-of-5 to spend. I don't see any way to do that without including all the public keys to spend even if the master key is spending.
1890 2013-11-08 18:45:50 <gmaxwell> huh?

1896 2013-11-08 18:46:34 <adam3us> gmaxwell: ok... was unclear if you meant some new script sig type, or it seems you just mean, yes so if you want to do that write a script that says so
1897 2013-11-08 18:46:36 <gmaxwell> ryan-c: He hasn't posted it. I said his name, so he can comment.
1898 2013-11-08 18:46:45 <ryan-c> gmaxwell: Ah.
1899 2013-11-08 18:47:03 <ryan-c> I couldn't think of any way to do what I want without a nested script hash scheme

1901 2013-11-08 18:47:06 <gmaxwell> in any case it worked just by running checksigs and accumulating in a counter on the stack, so it avoided repeating pubkeys.
1902 2013-11-08 18:47:21 <adam3us> ryan-c: as far as i understand its as simple as using an OR in the script (boolean logic)
1903 2013-11-08 18:47:26 <ryan-c> gmaxwell: Oh, I think I saw something like that.

1905 2013-11-08 18:47:58 <gmaxwell> yea, for what you're saying you just need a if{}else{} and let the redeemer pick.
1906 2013-11-08 18:48:01 <ryan-c> adam3us: Yeah, you can do it in a plain transaction, but then you'd have to put all the public keys in the output.
1907 2013-11-08 18:48:03 <adam3us> gmaxwell: can you use multisig OR sig ithout doing that manually
1908 2013-11-08 18:48:21 <adam3us> gmaxwell: (ok)

1910 2013-11-08 18:48:45 <gmaxwell> adam3us: well, what luke was trying to get was A+B OR {{A or B} + {C,D,E}} without repeating A or B keys.
1911 2013-11-08 18:49:06 <imton> helo: could you explain me that case? "the seller could refuse to sign the transfer to the buyer to get his coin back"
1912 2013-11-08 18:50:57 <ryan-c> so, i want to make a P2SH address with something like this: OP_CHECKSIG OP_IF OP_CHECKSIGVERIFY OP_ELSE OP_HASH160[a script] OP_EQUALVERIFY OP_EVAL OP_ENDIF
1913 2013-11-08 18:51:08 <adam3us> imton: well neither the exchange nor the user can force the other to complete the transaction it requires active participation of them both, one form of "participation" is to refuse to sign i which case the tx wont happen

1924 2013-11-08 18:53:30 <ryan-c> My concern is mostly not spamming the block chain with massive transactions in the normal case.
1925 2013-11-08 18:53:35 <gmaxwell> ryan-c: what you really want is AST hashtree scripts for that. If OP_CAT were enabled you could informally construct something equal to that, but it isn't.
1926 2013-11-08 18:53:49 <ryan-c> AST?
1927 2013-11-08 18:53:59 <imton> adam3us: ok, but what I see that this can't happen immediately automated by the exchange. In a limit order, the seller won't sign the txs (let's say he realizes about the matched buyer 5 hours later)
1928 2013-11-08 18:54:12 <Zarutian> ryan-c: abstract syntax tree
1929 2013-11-08 18:54:13 <gmaxwell> "Represent the script as a merklized abstract syntax tree. The P2SH address is the root. When spending the spender only may provide only the branch they are executing, and hashes for the unexecuted branches. This increases privacy and can compress long scripts on spend."
1930 2013-11-08 18:54:28 <ryan-c> ah
1931 2013-11-08 18:54:28 <imton> adam3us:... in the case he (the seller) is losing

1933 2013-11-08 18:54:32 <ryan-c> that's pretty cool
1934 2013-11-08 18:54:36 <ryan-c> yes, that would do it
1935 2013-11-08 18:54:55 <ryan-c> I don't see why i'd need OP_CAT there, though.
1936 2013-11-08 18:54:58 <Evilmax> ryan-c :p
1937 2013-11-08 18:55:13 <adam3us> imton: this is an issue, the cost of this model is the seller needs to be online
1938 2013-11-08 18:55:26 <adam3us> imton: eg have a smart phone app which accepts notificatins
1939 2013-11-08 18:55:41 <ryan-c> gmaxwell: As touched on here: https://en.bitcoin.it/wiki/User:Gmaxwell/alt_ideas
1940 2013-11-08 18:55:44 <gmaxwell> ryan-c: because you could construct a hashtree yourself in the script with OP_CAT.
1941 2013-11-08 18:55:44 <adam3us> imton: and if he doesnt respond in like some time period cancels the order

1951 2013-11-08 18:59:35 <ryan-c> I also wanted to be able to do multisig to addresses I don't have the public keys for, but I think one of Luke-Jr's scripts can do that.
1952 2013-11-08 19:02:07 <gmaxwell> ryan-c: it wouldn't need op_eval, ... the pubkeys are on the stack, you let the signature provide them and then you'd op_cat up some hashtree to verify them.
1953 2013-11-08 19:02:08 <ryan-c> Another thing that would be cool: Having a script that constrains how the output can be spent.

1956 2013-11-08 19:03:01 <adam3us> ryan-c: i agree, been bumping into that lately
1957 2013-11-08 19:03:10 <gmaxwell> as an aside, the AST thing is sipa's and roconnor's idea initially I believe.
1958 2013-11-08 19:04:14 <ryan-c> gmaxwell: I think I'm following. I think there's still the caveat is that there need to be enough OP_CATs to combine all the supplied pubkeys?
1959 2013-11-08 19:04:39 <ryan-c> sorry, edited that and it came out mangled, but I think what i'm saying is still clear
1960 2013-11-08 19:04:58 <gmaxwell> ryan-c: yea, unless you have a LOT of pubkeys any kind of tree compression is likely to be not so helpful.
1961 2013-11-08 19:05:35 <imton> adam3us: great, that was exactly the point I wasn't able to avoid/solve.
1962 2013-11-08 19:05:44 <gmaxwell> e.g. n/log2(n) is not a very big number for small n ... and especially not when its n/(log2(n)+c) with non-zero c.
1963 2013-11-08 19:05:44 <ryan-c> adam3us: Yeah, I wanted to be able to, say, make a transaction that specifies that the spend must look like 25% to address A, 25% to address B, 50% to address C.
1964 2013-11-08 19:06:12 <gmaxwell> ryan-c: output requirements have fungibility risks if not done very cautiously.
1965 2013-11-08 19:06:28 <adam3us> imton: its an inconvenience, but it could work, and maybe peopl would prefer that than having bitcoins at risk - i presume bitalo must be doing the same
1966 2013-11-08 19:06:38 <imton> adam3us: but I can't think of any other better option without the seller being active/online, if not the exchange would need to own the btcs.
1967 2013-11-08 19:06:52 <adam3us> imton: yes
1968 2013-11-08 19:07:03 <imton> adam2us: i'll be checking bitalo
1969 2013-11-08 19:07:25 <ryan-c> gmaxwell: Yeah. The use case I was thinking of is where you want to get a payment from someone that needs to be split up between a few parties. Would be nice if the sender didn't need to know/care how the split would be done.
1970 2013-11-08 19:07:33 <gmaxwell> (See https://bitcointalk.org/index.php?topic=278122.0 CoinCovenants thread as a sort of extreme logical conclusion of output restrictions)

1976 2013-11-08 19:09:40 <ryan-c> same basic idea
1977 2013-11-08 19:10:14 <adam3us> ryan-c: right, and the alternative falls back to server/bot has your bitcoin cos you cant do that
1978 2013-11-08 19:10:30 <ryan-c> adam3us: indeed.

1980 2013-11-08 19:11:14 <ryan-c> you might also want to have a payment that can be spent to either A or B but nothing else
1981 2013-11-08 19:11:42 <adam3us> ryan-c: well you can somewhat actually but only if you know the amounts up front, and/or you have enough money now floating around to pay the full years subscription, because each spend must spend the full and specific txin
1982 2013-11-08 19:11:57 <ryan-c> yeah
1983 2013-11-08 19:12:16 <ryan-c> oh, by signing transactions offline and sending them to the bot?
1984 2013-11-08 19:12:25 <ryan-c> which can then selectively broadcast them
1985 2013-11-08 19:13:58 <adam3us> ryan-c: well say you want to pay $10/mo for the next 12, you want a bot to do it for you, you want to be able to cancel without trusting the bot nor the service you're subscribing to, you put $120 on a coin and make 12 linked time-locked transactoins on the bot, qed
1986 2013-11-08 19:14:38 <ryan-c> are time locked transactions currently considered standard?
1987 2013-11-08 19:14:39 <adam3us> ryan-c: and you can presumably set that up so you can have another non-timelocked authority to just spend the money as a way of canceling the remainde
1988 2013-11-08 19:14:53 <gmaxwell> ryan-c: once the locktime has passed they're standard.
1989 2013-11-08 19:14:58 <ryan-c> ah
1990 2013-11-08 19:15:28 <adam3us> gmaxwell: i was thinking it might be ueful to have a p2p service that redundantly holds timelocked scripts and posts them after the date

2039 2013-11-08 19:29:11 <adam3us> gmaxwell: well (yes) but it relates to the lack of < timelock, so the way to implement a limit on a right (eg to exercise) is to have a timelocked authority to sweep the funds, you have to use that right in a timely fashion or the option holder gets a free extension; sure this can happen outside of bitcoin protocol
2040 2013-11-08 19:29:31 <adam3us> gmaxwell: but something that is at all central does not atomically self-execute so its a less smart contract IMO

2104 2013-11-08 20:27:43 <adam3us> imton: no by viral we were talking about the potential bad side effects of a proposed new bitcoin feature of the ability to write scripts can place limits on the output.. its unlikely to happen in years at the current rate of change; though it could have some useful usecases
2105 2013-11-08 20:28:32 <adam3us> imton: viral would be that if not prevented be possible to restrict all subsequent recipients of a coin, that would be bad as it could propagate through the bitcoin network and reduce functionaity
2106 2013-11-08 20:28:47 <adam3us> imton: or fungibility as gmaxwell said

2114 2013-11-08 20:34:11 <adam3us> imton: no they cant do that because the bitcoin is owned by the user and needs a signature from the user and a signature from the exchange

2128 2013-11-08 20:37:44 <adam3us> imton: well so like i said first step the seller transfers control of his bitcoin to the exchange and the seller combined (both must sign to make transactions after this step)
2129 2013-11-08 20:38:00 <adam3us> imton: second the exchange and user work together to accept a buy offer
2130 2013-11-08 20:38:30 <imton> got it so far

2134 2013-11-08 20:39:51 <adam3us> imton: so the exchange helps the user find a buyer, the buyer sends the user his address, the user signs the trnsactin to send the btcoin from the seller to the buyer, then the exchange has to cosign also
2135 2013-11-08 20:40:52 <adam3us> imton: so the user has tobe somewhat online for this to work or to receive push notification on a smart hone and to sign the transaction
2136 2013-11-08 20:42:56 <imton> great. and what about this "that delegated authority would allow what imton was talking about (type2 exchange) without the seller being online and without risk of coin theft on the exchange"
2137 2013-11-08 20:42:59 <imton> how would that work
2138 2013-11-08 20:43:40 <adam3us> imton: as far as i can see it cant work with current bitcoin script, we were talking about what changes would be necessary to the bitcoin script language to make that possible

2142 2013-11-08 20:45:59 stalled has joined
2143 2013-11-08 20:48:02 <adam3us> so the idea was if you could write into a bitcoin script that you authorized the exchange to pay anyone at all, but only if they paid your address the offer price

2145 2013-11-08 20:48:46 <adam3us> imton: however there are two gaps: you need both funds to be cryptocoins, and you need the script to allow you to reference the output addresses

2149 2013-11-08 20:50:41 <adam3us> imton: (then its safe to let the exchange do the transaction, or even any user without the exchange... the only way to receive your offer is to pay you the asking price)

2215 2013-11-08 21:28:14 <slush> hi, is there any problem with relaying transactions on the network?
2216 2013-11-08 21:28:41 <Luke-Jr> depends on what you consider a problem I guess
2217 2013-11-08 21:28:51 <slush> my transactions has 0 confirmations even with tx fee
2218 2013-11-08 21:28:51 <Luke-Jr> there's rate limiting..
2219 2013-11-08 21:28:58 <Luke-Jr> hmm, that does sound odd
2220 2013-11-08 21:29:06 <slush> and I don't see such transactions on BC.i, so I don't think they got propagated widely
2221 2013-11-08 21:29:09 <Luke-Jr> tx fee is large enough bitcoind type nodes care?
2222 2013-11-08 21:29:15 <Luke-Jr> BC.i is broken I think
2223 2013-11-08 21:29:55 <slush> 0.0001 BTC/kb is default, isn't it?
2224 2013-11-08 21:29:56 <phantomcircuit> slush, there isn't a general problem
2225 2013-11-08 21:30:09 <Luke-Jr> not sure

2231 2013-11-08 21:31:44 <slush> I'm having payout issues since yesterday. It worked for a year without any changes and since yesterday I see many unconfirmed transactions

2233 2013-11-08 21:34:56 <slush> sipa: great. then I don't understand why it isnt confirmed yet
2234 2013-11-08 21:35:16 <slush> there have been at least 3 blocks since broadcast
2235 2013-11-08 21:36:17 <gmaxwell> I have it on a node. it's not in my or eligius' GBT... but load has been high lately.
2236 2013-11-08 21:36:24 <gmaxwell> slush: are you attempting to mine it yourself?
2237 2013-11-08 21:37:41 <slush> gmaxwell: good point. I don't know because I don't have key to servers here :)
2238 2013-11-08 21:37:44 <midnightmagic> slush: I have it in my node
2239 2013-11-08 21:37:55 <wizkid057> eligius has it
2240 2013-11-08 21:37:56 <midnightmagic> .. nodeS
2241 2013-11-08 21:37:59 <gmaxwell> slush: do you expose getblocktemplate to miners?
2242 2013-11-08 21:38:03 <gmaxwell> it's easy to test if you do.
2243 2013-11-08 21:38:12 <slush> great. let's sit and wait. Maybe it is really just because of higher traffic on the network
2244 2013-11-08 21:38:20 <sipa> it's also not in my GBT output
2245 2013-11-08 21:38:25 <slush> gmaxwell: no, just stratum
2246 2013-11-08 21:38:36 <wizkid057> I've noticed a huge increase in "can you mine my zero fee transaction?" requests the past 24 hours
2247 2013-11-08 21:38:40 <midnightmagic> slush: I have day-old txn (one even with a child that has a fairly high 0.01 fee) that still aren't confirmed yet. fwiw
2248 2013-11-08 21:38:44 <gmaxwell> e.g. ./bitcoind -rpcconnect=gbt.mining.eligius.st -rpcport=9337 -rpcuser=x -rpcpassword=x getblocktemplate '{"capabilities": ["coinbasetxn"]}' | grep `./bitcoind getrawtransaction 39d087fc79ee91a9a055dbda8661e37aba186c66e39c62591ddaa3ee33104e67`
2249 2013-11-08 21:38:59 <gmaxwell> wizkid057: network load has been high, people presumably moving coin to sell them, new users making transactions, etc.
2250 2013-11-08 21:39:10 <gmaxwell> which also happened around other all-time-high periods.
2251 2013-11-08 21:39:14 <Luke-Jr> slush: Eligius has that txid, but does not think it's worth mining.
2252 2013-11-08 21:39:27 <slush> Luke-Jr: low fee?
2253 2013-11-08 21:39:33 <Luke-Jr> slush: not sure why
2254 2013-11-08 21:39:35 <wizkid057> gmaxwell: yeah, Eligius blocks have been quite large
2255 2013-11-08 21:39:47 <Luke-Jr> slush: but I'd agree with it's decision if you're not using sendmany for payouts -.-
2256 2013-11-08 21:40:30 <midnightmagic> Luke-Jr: Is there a way to check and see whether eligius thinks a tx is worth mining?
2257 2013-11-08 21:40:36 <wizkid057> Luke-Jr: probably just more 0-fee txns in our blocks than normal
2258 2013-11-08 21:40:49 <midnightmagic> or is that what gmaxwell just pointed out
2259 2013-11-08 21:40:50 <pigeons> there has also been a several days issue with mtgox now clearing up they weren't sending btc out, sending outputs that hadn't yet confirmed, etc
2260 2013-11-08 21:40:53 <wizkid057> midnightmagic: go the gbt request gmaxwell posted to see if we are mining it
2261 2013-11-08 21:40:57 <slush> Luke-Jr: I'm using sendmany

2269 2013-11-08 21:41:47 <wizkid057> 2013-11-08 21:01:33 CTxMemPool::accept() : accepted 39d087fc79ee91a9a055dbda8661e37aba186c66e39c62591ddaa3ee33104e67 (poolsz 3410)
2270 2013-11-08 21:41:48 <slush> It is much bigger transaction and it also didn't go thru
2271 2013-11-08 21:41:56 <Luke-Jr> slush: same thing
2272 2013-11-08 21:42:19 <slush> Luke-Jr: accepted, but not worth of mining?
2273 2013-11-08 21:42:21 <Luke-Jr> yep
2274 2013-11-08 21:42:41 <gmaxwell> interesting, bc.i rejects slush's transaction reporting that it can't find the inputs.
2275 2013-11-08 21:42:46 <slush> strange. so what txfee do you see in gbt set?
2276 2013-11-08 21:42:58 <Luke-Jr> not worth mining = not in GBT
2277 2013-11-08 21:43:07 <Luke-Jr> oh, other txns
2278 2013-11-08 21:43:30 <slush> gmaxwell: this sounds interesting. Where did you find that on bc.i?
2279 2013-11-08 21:43:41 iceTwy has left ("Leaving channel")
2280 2013-11-08 21:43:44 <slush> gmaxwell: it shows me just "Transaction not found"

2282 2013-11-08 21:43:49 <gmaxwell> slush: tried to submit it via https://blockchain.info/pushtx
2283 2013-11-08 21:44:11 <slush> gmaxwell: well, I'm sending that from standard bitcoind 0.8.5
2284 2013-11-08 21:44:22 <slush> Any chance that the wallet.dat got corrupted somehow?
2285 2013-11-08 21:44:34 <gmaxwell> slush: nah, my node has it in the memory pool so its valid.
2286 2013-11-08 21:44:40 <Luke-Jr> more likely you have prior transactions unconfirmed
2287 2013-11-08 21:44:43 <Luke-Jr> and not many coins
2288 2013-11-08 21:44:46 <slush> hopefully its just a problem of bci
2289 2013-11-08 21:44:51 <midnightmagic> doh. I'm not in your gbt either Luke-Jr
2290 2013-11-08 21:44:54 <Luke-Jr> also, as mentioned, bc.i has been having issues
2291 2013-11-08 21:45:04 <gmaxwell> or one of the inputs is unconfirmed and has a mutant circulating in the network.
2292 2013-11-08 21:45:05 <wizkid057> bc.i has been missing transactions
2293 2013-11-08 21:45:05 <midnightmagic> nooooo ha ha
2294 2013-11-08 21:45:21 <wizkid057> have had a lot of complaints from mywallet users, "Eligius says it paid me but I dont see it!"
2295 2013-11-08 21:45:35 <gmaxwell> incidentally, the fact that you can't get a txid only gbt is a bit annoying for this applicationâ¦
2296 2013-11-08 21:45:59 <Luke-Jr> gmaxwell: grep txid
2297 2013-11-08 21:46:22 <HaltingState> gmaxwell, sipa did you see my post https://bitcointalk.org/index.php?topic=327931
2298 2013-11-08 21:46:24 <wizkid057> Luke-Jr: I dont think eloipool gbt returns them

2300 2013-11-08 21:46:34 <gmaxwell> Luke-Jr: yea...
2301 2013-11-08 21:46:51 <wizkid057> gmaxwell: so, hash them all ;)
2302 2013-11-08 21:47:11 <gmaxwell> wizkid057: yea... well, getting out of what I can do just at the commandline. :P
2303 2013-11-08 21:47:12 <wizkid057> i'm sure you could convince awk to do it somehow
2304 2013-11-08 21:47:14 <wizkid057> lol
2305 2013-11-08 21:47:26 <gmaxwell> I could actually use bitcoind decoderawtransaction.

2423 2013-11-08 23:29:37 <sipa> normally, it only works on mempool & unspent ones
2424 2013-11-08 23:29:50 <sipa> you can enable it by starting with -txindex
2425 2013-11-08 23:29:59 <sipa> but you'll need to reindex
