You'll lose more money with down time - trying to get this shit work 24/7 (night time is a huge issue here) - than you would by paying for electricity.

Agree with your points although I don't think Gox would be that unattractive. An outside investor would see a huge client base and an opportunity to turn things around.

This guy has -8 reps would it be okay to invest with him?

What do you call a buisness that has your money and won't let you cash it out for 3 weeks while currency plummets?

regardless, it was not necessary to include that type of wording. There are a range of phrases which may have been used to state that custom clients may require updating - post fix. This man has been blaming everyone but mt gox on the problems which mt gox are suffering, and this is just another snide comment. he is a liability.

Here is the link to the thread, where the patch addressing malleability was discussed:
https://bitcointalk.org/index.php?topic=8392.0

The whole MtGox goxing was only possible because:
1) They were issuing transactions with sloppy signature format
2) This was accepted by the network for some time
3) New bitcoin client with tightened rules was released
4) Their sloppy transactions started being rejected
5) Exploiters "fixed" those transactions
6) MtGox sloppy software didn't notice transaction went through
7) Mt-gox sloppy software didn't notice output's were spent (making them unaware that they lose coins). It didn't even lock outputs which are used in pending transactions!!
MtGox incompetent customer support resubmitted transactions manually without looking into issue and alarming developers. Or maybe they did, but developers were too busy/confident/not able to fix the problem.

Overall: MtGox are incompetent bunch of liers

Please keep this a technical discussion.

Gox proposes to use the hash of the signed string as a non-modifiable transaction id. Is it a good or bad idea?

I think for standard SIGHASH_ALL transactions this should work.

Well if I was the attacker then this is how I would go :

1) Buy some btc with cash from the exchange
2) Try to withdraw it using malleable transactions (for this I would need to make some arrangements)
3) Claim I have not received it and try to get them to send it again
4) Repeat steps 1-3 using different ips and accounts using small amounts so as to make the trace hard to detect.

Attack successful. If not get more than the amount of BTC I should get, it will at least bring the exchange/processor to a halt.

Win win win !!

Or am I missing something ? Would like to know if this is possible from the core devs/experts ?

PS : Obviously this would be successful with an exchange/processor who is using txid for his system. Otherwise the above fails.

It is not even clear that the malleability problem is solvable. Besides the problem that there is innumerable ways to transform a transaction to give it a different hash without affecting scriptSig validity, it is simply unknown whether it is possible to algebraically transform an elliptic curve signature without invalidating it. If so, then no matter what you do to cover up the other holes, that gaping one is left open.

Transactions are malleable. Deal with it. If a transaction is observed on the network that has the same input outpoints and the same outputs, it is the same transaction, and mtgox should treat it as such. This is a simple check to do, and trivial to automate.

Ok i have another question for someone who can answer :

How can Mt.gox be the third Highest in volume exchange BTC/USD at now days, acording   to   

http://bitcoincharts.com/markets/

How do you explain this

 

WOW, you must have huge balls to keep such an amount on Scox.

Generally speaking, I think we should fasten our seat belts and get ready for the worst scam in Bitcoin history. Let's face the facts. Most likely, the story about a technical issue is plain bullcrap. And by now, also the most naive Bitcoiner must have realized that Mt.Gox is not to be trusted as a trading platform leaving those crooks with only two options.

A: Take hundreds of millions in customer funds and disappear enjoying la dolce vita on some private island somewhere in the Pacific.
B: Announce that everything is back to normal and watch 99% of all customers instantly withdraw their coins.

As far as I am concerned, it's kinda obvious what it's going to be.

Not only do they face a simple decision, but it also seems like they got ready for this very moment quite a while ago. According to the article "The rise and fall of the world's largest bitcoin exchange" published on wired.co.uk (7th of November 2013), Mt.Gox not even has a physical office anymore. And of course Karpeles and his gang weren't seen in a very long time as well. Plus, they might start feeling some heat after Shrem and Faiella's arrest. 

Well, let's hope for the best while preparing for the worst.

Good luck.

i just did 7 withdrawals 1-2 btc, only 3 for 1 btc arrived

russian roulette is 83% chance of success actually. depends what you understand by success of course

ok, here is the latest announcement:

Statement Regarding BTC Withdrawal Delays

Tokyo - JAPAN - February 07, 2014

Dear MtGox Customers,

During our efforts to resolve the issue being encountered by some bitcoin withdrawals it was determined that the increase in withdrawal traffic is hindering our efforts on a technical level. As to get a better look at the process the system needs to be in a static state.

In order for our team to resolve the withdrawal issue it is necessary to temporarily pause all withdrawal traffic to obtain a clear technical view of the current processes.

We apologize for the extremely short notice, but as of now all bitcoin withdrawals will be paused, and withdrawals in the queue will returned to your MtGox wallet and can be re-intiated once the issue is resolved. Customers can still use the trading platform as usual.

Our team will be working hard through the weekend and will provide an update on Monday, February 10, 2014 (JST).

Again, we apologize for the inconvenience, and ask for your continued patience and support while we work to resolve this issue.

Best regards,

The MtGox Team

Most of the failed transactions will never go through because one of the input addresses has zero balance as it was spent earlier.
Only the few failing transactions, which have newly mined coinbase inputs, will confirm slowly and even then it will be 17 to 24 hours later.

Gox has to re-credit trading accounts directly for any btc withdrawal failing longer than a day, or PREFERABLY manually send to the customer's withdrawal address from a wallet with sufficient funds.
