bitstamp btc withdrawal problem

Dear Bitstamp users

Bitstamp’s exchange software is extremely cautious concerning Bitcoin transactions. Currently it has suspended processing Bitcoin withdrawals due to inconsistent results reported by our bitcoind wallet, caused by a denial-of-service attack using transaction malleability to temporarily disrupt balance checking. As such, Bitcoin withdrawal processing will be suspended temporarily until a software fix is issued.

No funds have been lost and no funds are at risk.

This is a denial-of-service attack made possible by some misunderstandings in Bitcoin wallet implementations. These misunderstandings have simple solutions that are being implemented as we speak, and we're confident everything will be back to normal shortly.

Withdrawals which failed on the 10th and 11th of February will be canceled and the amounts added back to the customer account balances.

We will communicate any further developments regarding this issue.

Thank you for your understanding!

Best regards
Bitstamp team

so this transaciton malleability can easily be fixed then?

My understanding is that, that would be the long term solution but short term it enough to make the exchange wallets so that this malleability doesn't matter or do any harm.

Normal user-to-user transactions are working fine. The problems come from automated systems that need some way to keep track of how much funds are available and whether transactions that have been sent were received properly. These automated systems often use the tx-id to keep track of transactions, but as we've seen, the tx-id is not a reliable identifier.

I have the same issue with bter, made two withdrawals yesterday at 11 and 13 gmt, both shown as completed yet nothing shows in the blockchain. One shows in vircurex as incoming transaction. I wonder how vircurex saw it yet blockchain.info or blockexplorer didn't.

I talked to the customer support threw qq yesterday and they told me not to panic that they should go threw. But that it will take hours. More than 15 hours passed already. I'm really hoping I don't have to talk to the support again tonight.

I also got a withdrawal from stamp on sunday at 18 gmt.

I missed some nice arb oportunities

Seems like this transaction malleability is a minor issue and of no threat to Bitcoin. I suspect this is the same issue facing the other exchanges. Of course, some people on this forum will try to spread FUD that Bitcoin is broken and you will never receive your BTC withdrawals etc.

I guess BTC withdrawals should be back to normal again within a few days at most after Bitstamp implements a solution.

Question:
Why is it that until yesterday no one's transactions were affected by Tx Malleability DDOS attacks, but once MtGox declares it to be their issue, all the sudden everyone else is hit by the same attack? Is it copycat hackers at work?

Maybe it gave some people an idea, or it gave people the right opportunity to use the exchange-rate tanking weapon they had been sitting on for a while.

There is still a large difference, the systems at Gox misuse TXIDs, other exchanges now are unable to process withdrawals because the stream of crap is creating a situation their systems aren't designed to deal with. It's a lot like comparing a server error to a ddos. The first one is a server issue, the second one needs to be mitigated.

Some possibilities:

1) The attackers became aware of the flaw only after MtGox made it widely known in their detailed technical announcement yesterday.
2) The attackers turned their attention away from MtGox to everyone else, after MtGox stopped BTC withdrawal requests.
3) The Bitcoin Foundation are behind the attacks, so that all exchanges and wallet providers become aware of the issue and are forced to fix their systems to prevent this from becoming a bigger issue later on.
4) MtGox are behind the attacks to divert blame, buy time and cover up their insolvency.
5) The attacker is someone who wants to cause panic, cause a market crash and then buy up cheap bitcoins.
6) A government (US, Russia, China...) are behind the attacks to try to discredit Bitcoin.
7) Russian hackers are behind the attacks and want you to enjoy watching Sochi (instead of sitting behind a computer all day).

Note it's not just withdrawals that are stopped. They've stopped processing BTC deposits too. The article was edited to reflect that change.

My 8 BTC withdrawal from this morning is still listed as "Finished" and nothing has been added back.

The wording "will be" used in the Bitstamp news post implies action to be taken in the future, not action already taken. I assume failed withdrawals will be credited back once the fix is in place.

why does the idiot market still pays 27 % more for imaginary bitcoins stuck at Bitstamp than for imaginary coins stuck at

Gox  ?   Bitstamp will fix it in an 27 % earlier timeframe ?

don´t forget Mt. Gox is easier to sue when found empty ;-)

Mt gox can be found empty, and if that is the case, what are you going to get after suing them, imaginary fiat?

Bitstamp on the other hand is believed to have both coins and cash available. If it was up to me I would let gox go all the way down to 0...

24 hours.  No BTC received, no BTC added back to balance and no word from support.

looks kinda grim. any Russian speaking people here? I just used googletransl.

I don't think they mean btc withdrawals, they mention "Пpивaтбaнк/privatbank".

What is your problem?  I am not affiliated with MtGox in any way, except as a normal user.  If you are going to reply to all posts from MtGox customers telling them they are shills, I think you should go outside and play instead.  On the highway or something.

I was in shock for a short time, thank you.
delayed Wire transfers are not that horrible thought.

I asked a friend who knows a few words Russian, and he confirmed it is related to wire transfers.
