Conclusion: Bitcoin-Qt/bitcoind does not track changed transactions properly. Changed transactions will show up as a new transaction, and I would need the "new txid" thing to track those properly. It is not only MtGox. Services using bitcoind, like mine, may be vulnerable as well.
Hm, wonder if this explains why I've heard all other exchanges updating their systems as well. I believe this mutability issue is not as "insignificant" as the core dev team is attempting to convey.
Yes, the problem may be sperading. I have been waiting more than three hours now for the withdrawal of the rest of my BTC from Bitstamp. #bitcoin-otc is full of other people with the same problem. Anyone else experiencing problems withdrawing BTC from other exchanges today? The withdrawal is marked "Finished" in my Bitstamp transaction history. I have tried to contact support there, but no answer yet.
you make it up as you go along. nobody in the entire universe except you is having problems with bitstamp
Seems to be a
common problem.
Reddit is full of it as well. Both Bitstamp and BTC-E. I don't know if it is related to MtGox's problem or not. So far only Coinbase and blockchain.info released statements claiming they were not affected by the issue, and Coinbase wasn't exactly clear about it..
both bitstamp and coinbase are still allowing thier customers to cashout to wallets and thier customers are not being forced to short sell because of mass panic that mt gox induced created.People like yourself are able to take advantage of those not being able to cashout and are doing just that. If Mt gox had a shred of concern about their customers they would implement alternative withdrawl to wallets instead of halting cashouts trapping certain peoples money while allowing people like you to take advantage and make huge profits.
Agreed. Mtgox should have halted trading before halting withdrawals of BTC. Obvious market manipulation while MTGOX collects fees on every trade. Utter BS.
Meanwhile, about 8 hours after suspending withdrawals, Bitstamp withdrawal suspension is official:
https://www.bitstamp.net/article/bitcoin-withdraws-suspended/And BTC-E:
https://twitter.com/btcecom/status/433249934456807424None of the exchanges have halted trading. But MtGox should just because they were first? I'd like to hear that one explained.
And blockchain.info, which were "not affected" have problems as well:
16:35 < amantonop> Andreas M. Antonopoulos here, from blockchain.
16:35 < amantonop> We are detecting bot activity attempting to exploit the
TX-Malleability issue
16:37 < amantonop> I am acting as incident coordinator for blockchain.info and
we require assistance from the core developers.
16:37 < petertodd> amantonop: howdy
16:37 < amantonop> Hi Peter
16:37 < petertodd> amantonop: bc.i lets users spend unconfirmed outputs?
16:37 < amantonop> No the issue is not affecting customer wallets
16:37 < petertodd> amantonop: ah good
16:38 < petertodd> amantonop: what is the issue for you then?
16:38 < amantonop> Can you contact me on skype so I can explain in less public forum?
16:38 < petertodd> amantonop: sure
Bitcoin-Qt not affected? Yeah, right:
16:44 < Luke-Jr> BB-Martino: bad in what sense?
16:45 < BB-Martino> Bad in the sense that you can't really trust TXIDs. For
example if someone sends coins somewhere and it doesn't get
credited, and he wanted to post a TXID to prove it's there,
it'd be problematic.
16:46 < BB-Martino> My "" account growing more and more negative by every hour
is also bad.
16:47 < Luke-Jr> BB-Martino: you're not supposed to "trust" txids.
16:48 < Inception> Hi. Can anyone confirm there is a possible malled tx attack
in progress?
16:49 < Inception> we are getting this: Error: The transaction was rejected!
This might happen if some of the coins in your wallet were
already spent, such as if you used a copy of wallet.dat and
coins were spent in the copy but not marked as spent here.
16:49 < helo> no such thing afaik
16:49 < Inception> we are 100% sure the wallet has no other copy
16:49 < Inception> and we just ran the resync. the problem appeared again
shortly
16:49 < BB-Martino> Luke: it's not about trust, maybe I put it wrong. It makes
debugging really hard.

17:24 < epscy> BB-Martino: i'm not a user of your site (BitBargain?), but I
think most users would understand
17:25 < BB-Martino> for a while, yes
17:25 < BB-Martino> but for weeks, i'm not so sure
17:25 < epscy> BB-Martino: tx maleability has been highlighted since gox raised
it in their press release, it's likely lots of people are now
trying to exploit it against every bitcoin service
17:26 < BB-Martino> yes, i see that in my default balance.
17:26 <@jgarzik> yep
17:26 < BB-Martino> "" : -21.08554493,
17:26 < BB-Martino> OH WOW!
17:26 < BB-Martino> it was only -7 yesterday
17:27 < BB-Martino> WAIT WHAT !@#?!@?#!?@#!?@#
17:27 < BB-Martino> btc@nl:~$ bit getbalance
17:27 < BB-Martino> 345.75519626
17:27 < BB-Martino> btc@nl:~$
17:27 < BB-Martino> it's supposed to be 176.33
17:27 < BB-Martino> my accounting is completely screwed.
17:27 < BB-Martino> GREAT.
I think MtGox may have a point after all. And for the claim that other exchanges work fine: I think not.
