24 2012-08-15 01:28:59 <gmaxwell> er fine.
25 2012-08-15 01:30:11 <jgarzik> gmaxwell: blockexplorer.com gets my old getblock patch, so that's probably additional coding to use getrawtx
26 2012-08-15 01:30:35 <jgarzik> gmaxwell: ('getblock' RPC provides a full JSON dump for a block, including full per-TX dump, in case you're not familiar with it)
27 2012-08-15 01:30:50 <jgarzik> plus, it probably requires an older version to patch in
28 2012-08-15 01:32:10 * gmaxwell cues luke to comment on getblock that provides full per-TX dump :)

118 2012-08-15 06:28:44 <midnightmagic> if I had a shorter chain but which represented more actual work, but still had the checkpoints as a base, would it cause a reorg to my shorter chain?
119 2012-08-15 06:29:13 <luke-jr> yes
120 2012-08-15 06:29:29 <phantomcircuit> midnightmagic, that's actually not possible
121 2012-08-15 06:29:36 <phantomcircuit> wait
122 2012-08-15 06:29:38 <phantomcircuit> maybe it is
123 2012-08-15 06:29:40 <midnightmagic> thanks. i knew it didn't go the other way (less work, longer chain)
124 2012-08-15 06:29:41 <phantomcircuit> yes it is
125 2012-08-15 06:30:10 <luke-jr> hmm
126 2012-08-15 06:30:14 <luke-jr> I wonder if that's exploitablre
127 2012-08-15 06:30:20 <phantomcircuit> of course it would require a 50% attack
128 2012-08-15 06:30:21 <midnightmagic> i'd just have to magically mine at a much higher difficulty for a while in secret.
129 2012-08-15 06:30:25 <jgarzik> midnightmagic: yes, it will reorg to a shorter chain, if the shorter chain's total work is > the longer chain
130 2012-08-15 06:30:26 <luke-jr> phantomcircuit: no?
131 2012-08-15 06:30:36 <phantomcircuit> luke-jr, im not sure
132 2012-08-15 06:30:41 <midnightmagic> jgarzik: thanks, i like triangulation
133 2012-08-15 06:30:51 <luke-jr> get the difficulty on your chain high enough to counter the current chain with 1 block
134 2012-08-15 06:30:54 <luke-jr> then hope you get lucky
135 2012-08-15 06:31:08 <luke-jr> 64% chance you'll find it with the same work as the main chain would take to get thereâ¦
136 2012-08-15 06:31:19 <midnightmagic> it would be similarly as likely as just mining a longer chain normally wouldn't it?
137 2012-08-15 06:31:31 <phantomcircuit> actually
138 2012-08-15 06:31:31 <luke-jr> midnightmagic: no, it would just be amazingly lucky
139 2012-08-15 06:31:35 <midnightmagic> (presuming identical work)
140 2012-08-15 06:31:36 <phantomcircuit> i guess you could do it
141 2012-08-15 06:31:45 <phantomcircuit> by screwing with the timestamps in your chain

143 2012-08-15 06:32:01 <luke-jr> midnightmagic: 64% chance you could get away with less actual work
144 2012-08-15 06:32:07 <phantomcircuit> but you would need to either be ridiculously lucky or have WAY more processing power than the main network

146 2012-08-15 06:32:27 <luke-jr> phantomcircuit: but you'd only need to be lucky ONCE
147 2012-08-15 06:32:37 <midnightmagic> luke-jr: .. I have go explain in brush strokes bitcoin to someone, i'll be back later. I'd really like to know how you arrived at the 64% figure.
148 2012-08-15 06:32:53 <luke-jr> midnightmagic: 64% of blocks are found with less than average shares
149 2012-08-15 06:32:54 <phantomcircuit> luke-jr, well you'd probably need to be lucky for 2016 blocks
150 2012-08-15 06:33:19 janfrech has joined
151 2012-08-15 06:33:21 <phantomcircuit> since the target recalculation only happens on the boundary and blocks with the wrong target are rejected

153 2012-08-15 06:33:32 <midnightmagic> or you just wait for teh 2016th

156 2012-08-15 06:33:49 <luke-jr> midnightmagic: then you're limited to how much you can change it
157 2012-08-15 06:33:57 <phantomcircuit> midnightmagic, the recalculation takes into account all the blocks in the last group
158 2012-08-15 06:34:04 <luke-jr> phantomcircuit: no, it doesn't
159 2012-08-15 06:34:08 <phantomcircuit> it doesn't?
160 2012-08-15 06:34:09 <luke-jr> phantomcircuit: it's last - first
161 2012-08-15 06:34:12 <phantomcircuit> oh
162 2012-08-15 06:34:23 <luke-jr> but you can't set your block's timestamp more than the median of the last N blocks
163 2012-08-15 06:34:25 <midnightmagic> except.. hrm. 2016th timestamp is ignored in retarget
164 2012-08-15 06:34:27 <luke-jr> s/more/before
165 2012-08-15 06:34:48 <midnightmagic> anyway doesn't matter. bbl
166 2012-08-15 06:35:20 <phantomcircuit> midnightmagic, basically you'd be trying to skyrocket the target by screwing with block timestamps and then getting lucky with a single ridiculously low target block
167 2012-08-15 06:35:38 <phantomcircuit> i suspect if you worked out the numbers you'd find a 51% attack to be easier

262 2012-08-15 10:22:34 <zveda> sipa, but I read in the 'scaling bitcoin' discussions
263 2012-08-15 10:22:39 <epscy> sipa: is there a plan to increase the block size so the chain can handle more transactions?
264 2012-08-15 10:22:46 <zveda> yes the block size
265 2012-08-15 10:23:11 <zveda> https://en.bitcoin.it/wiki/Scalability#Current_bottlenecks
266 2012-08-15 10:23:26 <zveda> "Once those limits are lifted, the maximum transaction rate will go up significantly. "
267 2012-08-15 10:23:34 <zveda> Seems to imply that the fork is imminent .. ?
268 2012-08-15 10:24:08 <epscy> zveda: i don't think the wiki is neccessarily up to date
269 2012-08-15 10:24:21 <epscy> someone may have wrote that a couple of years ago
270 2012-08-15 10:24:35 <zveda> hm I see
271 2012-08-15 10:24:38 <zveda> so what's the plan now
272 2012-08-15 10:24:45 <zveda> to deal with the block size?
273 2012-08-15 10:24:50 <zveda> or just leave things be ?
274 2012-08-15 10:25:02 <epscy> i think it is to leave things be
275 2012-08-15 10:25:05 <justmoon> I think for now most people are focusing on improving scalability and performance
276 2012-08-15 10:25:06 <epscy> for the time being
277 2012-08-15 10:25:14 <justmoon> we need to be ready to deal with larger blocks before we allow them
278 2012-08-15 10:25:29 <sipa> in case the transaction rate goes up even more, space in blocks will become more expensive
279 2012-08-15 10:25:44 <sipa> so at that point, tx fees may become more relevant
280 2012-08-15 10:25:46 <epscy> gmaxwell has written about how bitcoin doesn't need to scale to visa levels of transactions, it can be used as a clearing house
281 2012-08-15 10:26:02 <sipa> yes, bitcoin is a currency, not a payment processor
282 2012-08-15 10:26:32 <justmoon> sipa: I disagree with gmaxwell (and many others) on that
283 2012-08-15 10:26:37 <sipa> it can be used as a simple payment processor directly, but it is slow and hard to use as one
284 2012-08-15 10:26:42 <sipa> justmoon: i know
285 2012-08-15 10:26:46 <justmoon> by the same token you could make a micropayment network and use paypal as a "clearing house"
286 2012-08-15 10:27:07 <justmoon> the benefit comes from having a common standard for transaction directly
287 2012-08-15 10:27:27 <epscy> zveda: https://en.bitcoin.it/wiki/Talk:Scalability#Response_from_Gregory_Maxwell
288 2012-08-15 10:27:48 <sipa> sure, i think bitcoin has many advantages over other currencies, when you want to build an electronic payment processor on top of it
289 2012-08-15 10:28:49 <zveda> I see thx

291 2012-08-15 10:31:03 <justmoon> sipa: the price of payment processors doesn't come from their clearing costs, but from their market position. if bitcoin is used merely in the background, then the payment processors with the best adoption will still be able to charge high premiums
292 2012-08-15 10:31:49 <epscy> justmoon: i think the difference is that getting set up with a visa merchant account can be a costly and time consuming process
293 2012-08-15 10:31:57 <epscy> this is not true of bitcoin
294 2012-08-15 10:32:29 <epscy> so if any payment processor acts too "evil" the barrier to entry for a competitor is very low

298 2012-08-15 10:33:59 <epscy> and it would be difficult for one bitcoin payment processor to prevent users from moving to another

300 2012-08-15 10:34:30 <justmoon> epscy: not necessarily, since payments from processor to processor would be more expensive then internal payments
301 2012-08-15 10:34:35 <epscy> justmoon: the problems you identify aren't technical, they are economic and social
302 2012-08-15 10:35:01 <justmoon> epscy: yes, I think there is no technical reason to limit the scale of bitcoin only economic and social ones
303 2012-08-15 10:35:04 <epscy> justmoon: if the user can withdraw btc then i don't see the problem
304 2012-08-15 10:35:46 <justmoon> epscy: if you switch payment processors you can still transact with the people using that payment processor, it'll just cost more
305 2012-08-15 10:36:04 <justmoon> it'll be more like the banking system we have now, or like the mobile phone market
306 2012-08-15 10:36:30 <epscy> justmoon: i think there are technical limits to bitcoins ability to scale

310 2012-08-15 10:36:43 <epscy> look at the problems we have with the size of the blockchain already
311 2012-08-15 10:37:11 <justmoon> that's because currently there is no way to distribute verification work across multiple nodes that don't trust one another
312 2012-08-15 10:37:19 <epscy> justmoon: also it would be different from the current system, in that you can send btc directly to people
313 2012-08-15 10:37:28 <epscy> in theory that should keep the PP honest
314 2012-08-15 10:38:29 <justmoon> you can also send money using other methods to people today, that only keeps western union "honest" to the extent that this other method is competitive price-wise
315 2012-08-15 10:38:42 <justmoon> remember our premise is that bitcoin transactions get relatively expensive

319 2012-08-15 10:40:13 <justmoon> epscy: all I'm asking is that we assume that the existing tasks a bitcoin node performs can be decentralized and that if we introduce new features that are mandatory for mining nodes that these features fulfill the same criterion
320 2012-08-15 10:40:19 <epscy> i don't believe bitcoin will ever be the only currency used
321 2012-08-15 10:40:58 <epscy> but bitcoins low barrier to entry and openness will hopefully encourage other financial services to compete more fairly

330 2012-08-15 10:43:22 <epscy> this is the problem bitcoin has with satoshidice
331 2012-08-15 10:43:24 <justmoon> namely your work will be entirely wasted
332 2012-08-15 10:43:41 <zveda> if somebody creates a really big block, the other miners could orphan it
333 2012-08-15 10:43:43 <grondilu> what about the head-only client? Wouldn't that solve the problem of the size of the blockchain?
334 2012-08-15 10:44:00 <zveda> we can leverage the democracy of bitcoin more perhaps
335 2012-08-15 10:44:17 <justmoon> grondilu: currently verification requires a dataset which is ultimately O(n) for n transactions
336 2012-08-15 10:44:46 <justmoon> grondilu: to fundamentally change the scalability properties without giving up on decentralization we need untrusted nodes to cooperate on verification
337 2012-08-15 10:45:39 <justmoon> for that you need a protocol that makes it impractical for somebody to create an invalid transaction and get all the verification assigned to himself

339 2012-08-15 10:45:51 <grondilu> a single client does not have to know the whole dataset. It only has to know transactions of the blocks where comes incoming paiements.
340 2012-08-15 10:46:37 <justmoon> ? can you rephrase I didn't understand that sentence
341 2012-08-15 10:46:55 <grondilu> a single client does not have to know the whole dataset. It only has to know transactions of the blocks where come incoming paiements.
342 2012-08-15 10:47:06 <zveda> lol
343 2012-08-15 10:47:09 <justmoon> ^^
344 2012-08-15 10:47:15 <justmoon> the s wasn't the problem :)
345 2012-08-15 10:47:21 <grondilu> did I write soething silly?
346 2012-08-15 10:47:41 <justmoon> so to verify transactions you need to know that the outputs they are spending haven't been spent
347 2012-08-15 10:47:58 <justmoon> right now the only way to know for sure is if you have seen all transactions
348 2012-08-15 10:48:02 <grondilu> oh. Indeed.
349 2012-08-15 10:48:27 <epscy> i think you guys are underestimating the likelihood of people trying to disrupt bitcoin
350 2012-08-15 10:48:36 <epscy> mining still isn't that expensive
351 2012-08-15 10:49:07 <epscy> and if someone was motivated enough they could really grow the blockchain
352 2012-08-15 10:49:08 <zveda> bitcoin decentralization is already kind of compromised since most clients are not mining. Since we trust the miners with including and excluding transactions, why not trust them to set the blocksize as well ?
353 2012-08-15 10:49:41 <freewil> well we dont just "trust" them to include txs
354 2012-08-15 10:49:44 <freewil> thats what fees are for
355 2012-08-15 10:49:51 <justmoon> zveda: I with you, I do think miners should set the block size
356 2012-08-15 10:49:57 <justmoon> I'm* with you
357 2012-08-15 10:50:02 <zveda> they can still decide to ignore any tx's they want

361 2012-08-15 10:50:50 <epscy> if you think that would be a significant advantage
362 2012-08-15 10:51:24 <justmoon> epscy: scalability is only an advantage if capacity is a problem

368 2012-08-15 10:52:52 <grondilu> well, since miner can chose to exclude or include transactions anyway, it's pretty much the same as if they can decide the blockside already, isn't it?
369 2012-08-15 10:53:20 <epscy> grondilu: not exactly
370 2012-08-15 10:53:35 <epscy> they can't create blocks bigger than the block size
371 2012-08-15 10:53:52 <epscy> but yes some miners do put a single tx in a block
372 2012-08-15 10:53:57 <justmoon> the block size would be bigger than the block size?
373 2012-08-15 10:54:13 <epscy> justmoon: yes the block size limit
374 2012-08-15 10:54:18 <justmoon> ah, well good!
375 2012-08-15 10:54:31 <justmoon> we want them to process as many transactions as is technically feasible
376 2012-08-15 10:54:38 <sipa> justmoon: i'd fully agree with miners setting the block sise, if miners weren't the only ones that get paid
377 2012-08-15 10:54:57 <justmoon> sipa: who else should be paid?
378 2012-08-15 10:55:10 <sipa> everyone running a node
379 2012-08-15 10:55:23 <justmoon> why? they don't have to process full blocks
380 2012-08-15 10:56:09 <sipa> well, those who want to validate transactions do
381 2012-08-15 10:56:19 <justmoon> why would I want to validate transactions if I'm not mining?
382 2012-08-15 10:56:34 <sipa> if you want to accept payments, for example
383 2012-08-15 10:56:43 <justmoon> I don't care how I get attacked, and validation doesn't protect me against double spends
384 2012-08-15 10:57:28 RainbowDashh has joined
385 2012-08-15 10:57:34 <sipa> well, in a situation where only miners run full nkdes, i'm sure that others would want to too, just to be prudent and that what they get is reasonable
386 2012-08-15 10:57:35 <epscy> justmoon: the fact that the blockchain can be downloaded from multiple nodes, not all them mining, but all independently validating helps prevent people from taking over the network
387 2012-08-15 10:57:52 <sipa> meh, blockchain archival is a different problem

392 2012-08-15 10:58:50 <sipa> point remains that miners are the gatekeepers to the network, and all others that want to participate (for whatever reason)
393 2012-08-15 10:59:00 <sipa> are affected by their decision
394 2012-08-15 10:59:14 <justmoon> miners want to be able to spend their mining revenue

396 2012-08-15 10:59:21 <zveda> originally didn't satoshi envisage that every node is also a miner

398 2012-08-15 10:59:24 <sipa> yes
399 2012-08-15 10:59:35 <sipa> they have to keep the network running for them
400 2012-08-15 11:00:09 <epscy> zveda: yeah, as smart as he was he failed to predict mining pools and mining companies
401 2012-08-15 11:00:12 <sipa> but they have all incentive to make mining (and running full nodes) as centralized as possible

405 2012-08-15 11:01:18 <sipa> and eventually you end may end up with a system where mining is controlled by a cartel, and the rest just runs SPV nodes
406 2012-08-15 11:01:47 <sipa> which may also work (economically), but it is surely not what i'd like bitcoin to be
407 2012-08-15 11:02:08 <justmoon> firstly, historically, we know that cartels are unstable and self-destruct, because everyone in the cartel has a strong incentive to cheat
408 2012-08-15 11:02:15 <zveda> it would be pretty easy to challenge these cartels
409 2012-08-15 11:02:15 <justmoon> secondly how does verification help you against a cartel
410 2012-08-15 11:02:24 <epscy> miners are like congressmen, the protocol is the supreme court
411 2012-08-15 11:02:24 <justmoon> they can just squeeze you on fees
412 2012-08-15 11:02:39 <justmoon> epscy: we all know how great that worked :P
413 2012-08-15 11:02:43 <sipa> agree, these are separate issues
414 2012-08-15 11:03:13 <zveda> perhaps the miners need to follow a protocol too
415 2012-08-15 11:03:35 <sipa> the P2P network does very different things
416 2012-08-15 11:03:53 <sipa> it is used to bootstrap full nodes (download historic block data)
417 2012-08-15 11:03:55 <epscy> justmoon: yeah lets just get rid of all the checks and balances
418 2012-08-15 11:03:56 <justmoon> sipa: ironically the most realistic scenario for miners to actually corner the market is by getting a network-wise block size limit accepted :)
419 2012-08-15 11:04:04 <epscy> instead of trying to fix them
420 2012-08-15 11:04:15 <grondilu> is it possible to type something such as: "bitcoind backupwallet - |gpg -c |mail -s backup myself@somewhere.com" ?
421 2012-08-15 11:04:28 <justmoon> the harder the limit the harder it is for individual miners to cheat and include transactions more cheaply
422 2012-08-15 11:04:30 <sipa> grondilu: no, you'll need a temp file
423 2012-08-15 11:04:38 <grondilu> too bad, imho
424 2012-08-15 11:04:54 <zveda> it would be nice if I could send my transaction only to a certain miner
425 2012-08-15 11:04:56 <zveda> to reward them
426 2012-08-15 11:05:00 <zveda> for being good
427 2012-08-15 11:05:02 <epscy> justmoon: also i think you need to study history again, natural monopolies and cartels can and have lasted longer than a human lifetime
428 2012-08-15 11:05:09 <zveda> that would enhance the democracy
429 2012-08-15 11:05:11 <sipa> zveda: you can, just ask them how they want it
430 2012-08-15 11:05:34 <zveda> sipa, what do you mean ?
431 2012-08-15 11:05:44 <zveda> can I avoid 'broadcasting' my transaction ?
432 2012-08-15 11:05:53 <justmoon> epscy: a natural monopoly is something very very different from a cartel
433 2012-08-15 11:05:56 <sipa> just connect to them directly
434 2012-08-15 11:06:07 <zveda> oh ok
435 2012-08-15 11:06:08 <zveda> well then
436 2012-08-15 11:06:10 <sipa> -connect miners.ip.address
437 2012-08-15 11:06:19 <zveda> the mining cartels will have no clout
438 2012-08-15 11:06:35 <zveda> if there's any minor competitor, people will just connect to them.. and wait a bit longer
439 2012-08-15 11:06:51 <zveda> but much lower fees
440 2012-08-15 11:06:52 <epscy> justmoon: from the point of view of people being oppressed it usually isn't
441 2012-08-15 11:08:10 <epscy> i lean libertarian but this whole free market without regulation is dumb, demonstrably so by any good history book
442 2012-08-15 11:08:46 <zveda> hey what if we have say.. 10 grades of mining pools.. grade 1 the biggest and finds the most blocks, but charges the highest fees, down to 10 as the slowest and lowest fees. so you have 10 blocks being worked on constantly. you can get your transaction included in a block being worked on much faster.. tho it wont make it into the blockchain any faster
443 2012-08-15 11:08:54 <justmoon> epscy: how would you distinguish regulation from having a cartel?
444 2012-08-15 11:09:57 <sipa> anyway, the p2p protocol today: 1) download historic blocks for bootstrapping full nodes 2) communication channel between senders and receivers of transactions 3) broadcast communication channels for transactions to miners 4) blockchain status synchronisation (new recent blocks)... 1) can be moved to a different protocol, 2) is just stupid, 3) may get replaced over time
445 2012-08-15 11:10:29 <justmoon> the only people involved in the day-to-day operations of a regulatory agency are the people being regulated, the difference between a regulatory agency and a cartel is that I can choose to cheat the cartel and make more money, thereby destroying the cartel
446 2012-08-15 11:10:42 <justmoon> if I try that with a regulatory agency I will get fined / go to jail
447 2012-08-15 11:11:29 <zveda> regulatory agencies are also a kind of cartel
448 2012-08-15 11:14:13 <epscy> justmoon: if you are suggesting that the government is a cartel then you may be right
449 2012-08-15 11:14:29 <epscy> but at least it is a cartel that the average person has some influence over
450 2012-08-15 11:14:36 <justmoon> I'm not suggesting anything other than what I'm outright saying :)
451 2012-08-15 11:14:50 <epscy> though I don't believe western democracy is participatory enough
452 2012-08-15 11:15:00 <epscy> i think politics should be more local
453 2012-08-15 11:15:52 <justmoon> I strongly agree with that
454 2012-08-15 11:17:33 <justmoon> but I'm worried you might have set yourself up for a self-contradiction
455 2012-08-15 11:17:58 <justmoon> if you believe regulation is good, but government should be local, aren't you worried that companies will dodge regulation by moving?
456 2012-08-15 11:19:19 <epscy> nope
457 2012-08-15 11:19:27 <epscy> i mean they will
458 2012-08-15 11:19:38 <epscy> but it's not a big problem
459 2012-08-15 11:20:00 <zveda> so if I can interject for a second guys; so the block size limit doesn't limit the number of 0-confirmation transactions right ?
460 2012-08-15 11:20:26 <epscy> i can see lots of nearby localites adopting the same regulations, effectively having a treaty with each other
461 2012-08-15 11:20:26 <zveda> I mean I can potentially accept a >8 0-conf tps ?
462 2012-08-15 11:20:58 <epscy> the point is a single one should be able to opt out if the people there feel it is no longer in their interests
463 2012-08-15 11:20:58 <sipa> zveda: yes
464 2012-08-15 11:21:21 <epscy> if the regulation is bad, other localities will follow suit
465 2012-08-15 11:21:24 enquirer has joined
466 2012-08-15 11:21:35 <zveda> so really this block size limit doesn't affect micro transactions much.. since presumably they are fince to accept 0-conf
467 2012-08-15 11:21:42 <zveda> fine*
468 2012-08-15 11:21:46 <epscy> we should probably take the politics elsewhere
469 2012-08-15 11:22:40 <sipa> zveda: but those microtransactions could never end up in a block
470 2012-08-15 11:22:51 <sipa> or it will take longer and longer to get in
471 2012-08-15 11:22:52 <justmoon> epscy: yeah, I'm happy to end on that note, a pluralistic world like you describe is fine with me, what I'm worried about are those who want a global government
472 2012-08-15 11:22:55 <zveda> btw I can tell you guys are americans with all your regulations.. the world needs more 'unwritten rules' imho.
473 2012-08-15 11:23:16 <zveda> sipa, well eventually they should get in tho right? isn't there some sort of queue for low-fee transactions.. ?
474 2012-08-15 11:23:59 <justmoon> zveda: for the record I'm german :]
475 2012-08-15 11:24:49 <zveda> my naive point of view: in sports where you have a million rules and 5+ referees and a few video referees etc, you still have just as much if not more cheating, plus everything is more complicated
476 2012-08-15 11:25:41 <zveda> sipa, perhaps this queue could be put on the web somewhere
477 2012-08-15 11:25:44 <sipa> zveda: you just contradicted yourself
478 2012-08-15 11:25:59 <zveda> I did ?
479 2012-08-15 11:26:21 <sipa> if there is a limited queue, and you send more in than what can be mined, the queue will overflow
480 2012-08-15 11:26:29 <justmoon> zveda: "could be put on the web somewhere" <- blockchain.info shows a list of the unconfirmed transactions
481 2012-08-15 11:26:36 <sipa> and you to drop things from it
482 2012-08-15 11:27:22 <zveda> sipa, ah true good point
483 2012-08-15 11:27:33 <zveda> justmoon, yes, but I mean I'd like to see the place in the queue
484 2012-08-15 11:27:39 <sipa> also, if you talk aboit accepting 0-conf, you're using the p2p network as a communication channel between senders and receivers of transactions, and that is imho a usage that should disappear over time
485 2012-08-15 11:28:08 <sipa> it's useful for personal payments, and anonymous donations
486 2012-08-15 11:28:42 <justmoon> zveda: the place in the queue would be represented by what's called the priority - I believe there is some way to query the bitcoin client to get it to tell you the priority for a transaction
487 2012-08-15 11:29:12 <sipa> zveda: also, every node can have a different idea about that queue
488 2012-08-15 11:29:30 <zveda> well it's the miner's queue isnt it
489 2012-08-15 11:29:37 <zveda> the miner decides
490 2012-08-15 11:29:39 <sipa> there are many miners :)
491 2012-08-15 11:29:56 <zveda> yes
492 2012-08-15 11:30:09 <sipa> and they will most certainly not always agree
493 2012-08-15 11:30:20 <sipa> (if they always did, we already have a cartel)
494 2012-08-15 11:30:41 <justmoon> you guys are throwing the c word around a bit too lightly ^^
495 2012-08-15 11:30:42 <zveda> that's what I meant when I was talking about before.. if you have a tiered miners system.. where your fee level determines your tier.. then you'll know which queue you are in
496 2012-08-15 11:31:09 <sipa> justmoon: haha
497 2012-08-15 11:31:25 <sipa> would you prefer me to use the word monopoly in this case?
498 2012-08-15 11:32:04 <sipa> zveda: there are aleady such tiers: the different priorities within each's mempool
499 2012-08-15 11:32:21 <sipa> but you cannot have any global consensus about a single queue
500 2012-08-15 11:32:32 <sipa> that's just not possible theoretically
501 2012-08-15 11:32:40 <zveda> sipa, right, but I meant if each mempool would have a website with their queue
502 2012-08-15 11:32:51 <zveda> so you know when your transaction is being worked on
503 2012-08-15 11:32:54 <sipa> each node has such a queue
504 2012-08-15 11:33:26 <sipa> i think what you're aiming for is feedback from miners about their queue policies
505 2012-08-15 11:33:33 <zveda> yes
506 2012-08-15 11:33:38 <justmoon> sipa: well, I was going to say that simply because all miners use the same rules doesn't mean that there is a formal agreement between them (for example in the earliest days of bitcoin all miners would have been using the exact same rules and it wasn't because of a cartel)
507 2012-08-15 11:33:39 <sipa> so you can efficiently determine which fee you need for what.service
508 2012-08-15 11:33:44 <justmoon> maybe I'm too nitpicky :P
509 2012-08-15 11:33:53 <sipa> justmoon: that's not what i meant
510 2012-08-15 11:34:31 <sipa> justmoon: agreeing about the rules is not necessarily agreeing about the actual queue at a given point in time; the latter requires coordination between miners

666 2012-08-15 15:32:28 <zveda> ok THX
667 2012-08-15 15:32:43 <sipa> when... no idea

669 2012-08-15 15:35:20 <TD> zveda: there already are some

671 2012-08-15 15:35:41 <TD> zveda: if you mean explicitly, mode of bitcoin-qt, then yeah, not yet. but multibit and friends already are lightweight
672 2012-08-15 15:37:33 <Herodes> coinbase.com could be checked out as welll.
673 2012-08-15 15:37:34 <Herodes> :)
674 2012-08-15 15:38:02 <sipa> does coinbase.com have a client?
675 2012-08-15 15:38:04 <justmoon> Herodes: hosted clients are heresy, people have been quartered for less
676 2012-08-15 15:39:39 <Herodes> sipa: I didn't try it yet, just heard it was an easy way to get started with bitcoin.
677 2012-08-15 15:39:53 <Herodes> justmoon: :)
678 2012-08-15 15:40:01 <Herodes> for small amounts I don't see the big problem.

686 2012-08-15 15:41:05 <Herodes> i've read some discussions of it in the dev part of bitcointalk forum.
687 2012-08-15 15:41:16 <Herodes> obv block chain is getting big, and something has to be done about it.
688 2012-08-15 15:41:18 <justmoon> sipa: how come people call it an ewallet? it's not like other clients aren't electronic

698 2012-08-15 15:51:36 <zveda> do you guys worry about it ?
699 2012-08-15 15:51:45 <helo> tps reports?

702 2012-08-15 15:52:13 <zveda> yes
703 2012-08-15 15:52:22 <sipa> i think with some further optimizations we can easily deal with the load the current max block size allows
704 2012-08-15 15:53:13 <zveda> what about beyond that
705 2012-08-15 15:53:43 <sipa> whatever comes after that, is inevitably years ago, and we don't know what the bitcoin landscape will look like at that point
706 2012-08-15 15:53:48 <sipa> s/ago/away/
707 2012-08-15 15:53:54 <helo> it's kind of weird... to get people to use bitcoin, lots of vendors need to accept it. but if everybody used bitcoin for all of their transactions with vendors, there woulnd't be enough block space
708 2012-08-15 15:54:50 <sipa> they need to accept bitcoin-the-currency; that's not necessary the same as use-payments-that-are-mapped-1:1-to-bitcoin-transactions

719 2012-08-15 15:59:59 <wumpus> that wil be difficult unless we have determinstic wallet support, sure it's possible to print and scan 100+ private keys but...
720 2012-08-15 16:01:00 <sipa> brainwallet.org uses browser javascript, but it wouldn't be hard to turn it into a site that sends the private keys somewhere...
721 2012-08-15 16:01:38 <jeremias> I guess you can just download the html file and use it offline?
722 2012-08-15 16:01:45 <wumpus> I think the difficult part will be scanning them back in, qt has decent printing support but cross platform scanning is a wholly different beast
723 2012-08-15 16:02:27 <jeremias> I trust the creators of bitaddress.org and brainwallet.org
724 2012-08-15 16:02:50 <wumpus> maybe, but do you also trust everyone that (inadvertently) has access to their servers?

727 2012-08-15 16:03:57 <sipa> i trust them too, but i prefer a solution that doesn't require me trusting whatever site operator
728 2012-08-15 16:04:01 <jeremias> I trust they to handle the basic security stuff, and usually people don't share access to their servers
729 2012-08-15 16:04:35 <jeremias> yeah I prefer not trusting as well, but I choose to use my time for other things than thinking all the time about minimizing trusts
730 2012-08-15 16:04:42 <Herodes> jeremias: true, unless there exist rogue operators.

733 2012-08-15 16:05:00 <wumpus> basic security stuff might not be enough, remember that even linode got hacked for bitcoins
734 2012-08-15 16:05:01 <jeremias> people lose money on bitcoinica and stuff
735 2012-08-15 16:05:25 <Herodes> that's an insider job.
736 2012-08-15 16:07:05 <wumpus> in the scheme of things, inside or outside job doesn't really matter, somehow someone gains access to the server and poof are your coins
737 2012-08-15 16:07:37 <wumpus> sure of course it's a small issue if you use it only for a few coins for fun...

739 2012-08-15 16:08:04 <Herodes> wumpus: right.
740 2012-08-15 16:10:46 <wumpus> but arguably it's indeed somewhat more effort to steal your coins than with a straight-up online wallet

754 2012-08-15 16:40:20 <TD> i think it's inevitable that the bitcoin community will start to demand low-trust/high-security setups from operators
755 2012-08-15 16:40:36 <TD> there have been too many clever hacks and the financial incentives to do those hacks are too great
756 2012-08-15 16:40:47 <TD> you basically have to assume you will get hacked, no matter what, and build your systems accordingly

940 2012-08-15 20:51:55 CodeLion has joined
941 2012-08-15 20:52:02 <CodeLion> In the bitcoin protocol, what is involved in incrementing extraNonce? is that done locally or does it require a server connection?
942 2012-08-15 20:53:48 <sipa> depends which protocol you use
943 2012-08-15 20:54:02 <sipa> getwork does not permit local changes to the coinbase
944 2012-08-15 20:54:13 <sipa> the newer getmemorypool/getblocktemplate does
945 2012-08-15 20:55:44 <CodeLion> hmm... I guess my question becomes... what is the simplest way to increment the extraNonce? If I understand the protocol correctly, you incremement Nonce until it equals 0xFFFFFFFF or w/e then increment extraNonce
946 2012-08-15 20:56:29 <sipa> which protocol?
947 2012-08-15 20:56:50 <CodeLion> not the protocol... the algorithm. Sorry I mispoke

949 2012-08-15 20:57:23 <sipa> when the block nonce range is exhausted, you need a new block header to work with
950 2012-08-15 20:57:29 <CodeLion> Ah ok
951 2012-08-15 20:57:32 <CodeLion> so then you getwork?
952 2012-08-15 20:57:34 <sipa> how you create the new header doesn't matter
953 2012-08-15 20:58:06 <sipa> in case of the getwork protocol, yes you do a new getwork, or if rollntime is supported by the server, you can also try incrementing the timestamp
954 2012-08-15 20:58:26 <CodeLion> ok thanks sipa

1032 2012-08-15 22:09:36 <Diablo-D3> but maybe thats wrong, maybe the new world order should come out of many

1073 2012-08-15 22:31:39 <sipa> First attested in English 1829, the word numismatics comes from the adjective numismatic, meaning "of coins", borrowed 1792 from French numismatiques, which derives from Late Latin numismatis, genitive of numisma, a variant of nomisma meaning "coin"

1102 2012-08-15 22:43:37 <sipa> The noun exonumia is derived from two classical roots: exo, meaning "out-of" in Greek, and nummus, meaning "coin" in Latin

1180 2012-08-15 23:16:39 <sipa> that truncates
1181 2012-08-15 23:16:56 <sipa> and r+ doesn't create
1182 2012-08-15 23:17:05 <sipa> and a/a+ position at end of file
1183 2012-08-15 23:17:45 <Diablo-D3> a then seek to the start?
1184 2012-08-15 23:18:00 <Diablo-D3> er a+ then seek
1185 2012-08-15 23:18:45 <sipa> a+ seems to have very strange semantics (the manual says that read pointer is set to the beginning of the file, but the write pointer to the end?_
1186 2012-08-15 23:18:57 <Diablo-D3> sipa: ooh
1187 2012-08-15 23:18:59 <sipa> i don't get it, i must be missing something
1188 2012-08-15 23:19:11 <Diablo-D3> The fdopen() function associates a stream with the existing file
1189 2012-08-15 23:19:11 <Diablo-D3> descriptor, fd.
1190 2012-08-15 23:19:15 <sipa> this seems to me to be the most common way of opening a binary file
1191 2012-08-15 23:19:17 <Diablo-D3> Modes "w" or "w+" do not cause truncation of the file.
1192 2012-08-15 23:19:38 <sipa> when using fdopen, yes
1193 2012-08-15 23:19:48 <sipa> but want to open a file, not copy a file descriptor
1194 2012-08-15 23:20:16 <Diablo-D3> open and open again?

1205 2012-08-15 23:32:34 <sipa> Luke-Jr: of course, i'm using fseek to get to the place i need, but i don't understand why i must either 1) use open() directly, 2) do two calls to fopen, or 3) cause a pointless seek to the end of the file by opening in 'a+'
1206 2012-08-15 23:32:59 <Luke-Jr> sipa: is there actually a cost to seeking?
1207 2012-08-15 23:33:08 <sipa> probably not, but it feels stupid
1208 2012-08-15 23:33:27 <Luke-Jr> "open for read+write, position at beginning, don't truncate" is a very odd combo IMO
1209 2012-08-15 23:33:58 <sipa> how would you open a binary file in which you're going to make changes?
1210 2012-08-15 23:34:49 <Luke-Jr> a+
1211 2012-08-15 23:37:32 <sipa> what if there is no reason to assume the first write will be at the end?
1212 2012-08-15 23:37:45 <Luke-Jr> still a+ :p
1213 2012-08-15 23:38:15 <Luke-Jr> afaik, it's just a matter of newstruct->pos = do_append ? endoffilepos : 0;
1214 2012-08-15 23:41:56 <sipa> i still don't see why not expecting to be placed at the end of the file is such an odd wish
