re: miners haven't incentive to do anything. Do they really? Only if you're mining solo... otherwise all that matters is what the pool you're mining on is using.
to reply to myself i think there would have been a lot less ppl running around if it had been made clear that all that really matters is what client the pool you're operating on is using as a person that mines @ a pool, i'm not downgrading from 0.8 nor am i downgrading my relay node

Downloading blockchain on 0.7 bitcoind. Pool will be back up when that is done. Sorry for all the chaos.
don't have a backup pool configured anymore, so i guess i'll just wait hope it doesnt take like 8 hours =p

Hi, I'm mining using a 5830 and only getting around 170Mhash/s. Even OC, I still only get around 200 Mhash/s. I'm currently running catalyst v12.10 and opengl version 6.14.10.11931. Most people say that they normally get at least 300Mhash/s. What should I do to try to fix this?
use www.nogleg.com/archive/barelyclocked.rarunrar it somewhere, type barelyclocked if there's one gpu, it'll be gpu 0 so then barelyclocked gpu=0 memory=160 barelyclocked gpu=0 core=1000 barelyclocked gpu=0 vddc=1.163 (not necessary in this case, since it defaults to performance level 3) then cgminer should run at 128 worksize, 2 vectors, and you should get ~320-325mhash most cards can run at 900-930/160 @ 1.063v & 730-790/130 @ 0.95v, which is better depending on the cost of your electricity. the 1.063v option is better in almost all cases manually edit cgminer.conf file so that your fan speed doesnt max out at 85%

And what are you thinking they will do with this one block that they create? To do anything destructive they would need to have the ability to regenerate old blocks that are already part of the blockchain or sustain continuous control over all new blocks. Generating a single block makes you a miner, not an attacker.
An attacker with 25% capacity might be able to notice a tie and then continually exploit it by causing subsequent ties. He could connect to every node so he's aware of exactly when someone else finds a block, and send out his own at that time (he has found one by now with p=0.5), to generate another tie. So, the probability of him generating n blocks in a row would be (1/2)^n; e.g. he'd have a 1/4 chance of controlling two blocks in a row. How many blocks does an attacker need to generate in a row in order to cause trouble? these two transactions are similar to what happens when there is a "tie" on blocks: http://blockchain.info/tx/5ae820ef31cc5a3d1a34f7373d0b675cacc74786c160317d8648c24933f55874First Seen 2013-03-08 11:04:13, relayed 1566 http://blockchain.info/tx/7a6a8ea2c4b2eed6b5ceee2d1b3783e293f00773a6d7f9cc5ac106b826efd49dFirst Seen 2013-03-08 11:04:13, relayed 63 not really much relevance anyway. what is someone going to do with this evil tie breaker block? maybe if it was an evil tie breaker block followed up by another 5 or so.. anything w/ improper transactions would get turned down by 99% of nodes (if snoopy is running somewhere, it'd grab it) but really the closest you'll get to ties are when some pool with a well connected bitcoind is a few seconds later than one without.. btcguild comes to mind, they've had at least two clear losers a few seconds and a few transactions earlier than some other pools, but got lucky by getting next block anyway.. p2pool would be another good example (depending on who solves it) (oh, in case someone doesn't look at the transactions themselves instead of the node list: #1 http://blockchain.info/tx-index/59188147/5ae820ef31cc5a3d1a34f7373d0b675cacc74786c160317d8648c24933f55874#2 http://blockchain.info/tx-index/59188145/7a6a8ea2c4b2eed6b5ceee2d1b3783e293f00773a6d7f9cc5ac106b826efd49dcrafty.. i guess... the 145 one was actually sent first .. oh, is it just me, or did satoshi dice really get owned there?

well, i tried to market sell some bitcoins on mtgox and they've been sitting there for 10 minutes ok, after i wrote this i went and relisted it as a sell at $1 and it sold for 45 it was $46.85 or something like that when i initially put it in as a market sell Gox hardly refreshes their latest price quote, by the time you issue the order the bid you saw could have been long gone. it was a market sell, that's supposed to be executed immediately it wasn't i removed it after 10 minutes (this was an hour ago, or so) then i put in a sell order at $1 and that went through after about 5 seconds but perhaps it was just my market order finally completing, even though i had removed it already

Are the visiontek 7970's reference cards? I'm interested in a couple of them.
Yes, all reference how long have the 7970's been mining? did you get them when they were first introduced? i'd like to grab a 7970 or 6990 for gaming at some point (though I do get the feeling I should probably wait a couple months, seems like some ppl are still buying GPUs to *start* mining with)

Just one more reason to expatriate to St. Kitts.
malta has some very easy to meet residency requirements ed: oh, can they move your money? i was under the assumption i'd have to accept some new ToS whenever this move is finalized (mar 20th?)... and at that point i'd refuse the ToS and just withdraw all to dwolla? The way they see it, is that it is THEIR currency and as such they like to be able to track it down to the n'th degree. since 9-11, yeah 'patriot act' and all that

zvs, what software is on server side? These late and duplicated notifications looks like bug in server side implementation.
Oh, Windows 7 Ultimate 64bit I was going to retest it later with minerd running 1 thread and affinity to 1 core with graphic cards at something like 0 intensity to see if that might have been causing it... (minerd wasn't maxed before, but it was still pretty heavy on the cpu)

Hi Bracek, what do you mean by 'access'? Do you mean read access? If so, then once we've transitioned, our chief compliance officer will have access to verification documents, or someone else on our AML/KYC team.
Hang on a second. Where in the MtGox TOS does it say MtGox has the authority to sell sensitive identity information to third parties without the express written permission of the account holder. Last time I checked with wasn't a merger. I gave my identity documents to MtGox not Coinlabs. Did it even occur to you that you have no legal right to that information. Is it going to take a lawsuit? You had your chance to keep your identity documentation private and from the sound of things, you blew it. In my mind, sending off one's identity docs to anyone is a one-time thing. Think of it as a tattoo or a circumcision. You might get lucky and realize no ill effects, but it's damn hard to undo completely. Maybe getting all lawyered up (likely a yawn inspiring hollow threat like 99.9% of them) might help, but how are you going to know? i'm not sure what country you live in, but since this new entity is going to be located in the USA, there are privacy laws in the USA that would prevent such information from being handed over w/o person's acknowledgement

How does this work? I assume you will give the private key to an address that someone buys. But then you also have the keys. So, after purchasing from you, you can still access any funds that are sent to this address.
Or, is there something that I have not understood.
It doesn't work. But 4 letter vanitygen addresses are trivial, regardless..
