There is no such thing as "fixing private keys".   Private keys are simply random 256 bit numbers.  You either have them or you don't.

If MtGox either
a) doesn't have the private keys for the coins in their wallet
or
b) they have the private keys but the coins have been moved (given to attackers, stolen years ago in prior hacks, embezzled)

there is nothing short of a hard fork to mint new coins for MtGox that anyone can do.

I have a question:
I do understand that private keys are random numbers, but at same point they have to be created on deterministic factors like time etc. So when the private key would be let's say a hash of the "magic_number"+timestamp, then there is a chance to rebuild the private key, if you have the magic number and the timestamp. For the sake of simplicity let's assume the bug is that a letter x got added to the private key. So no private key would work anymore.
-> So in this case there would be a feasible way to compute the private keys.

But I have no idea how MtGox created the private key. Maybe they took something that can't be found like Marc used 500 random characters (just pushed his hands on the keyboard).

So based on what private keys get created in the qt wallet?

The QT client uses the OS level random number generator to generate private keys.  If values of PRNG could be recomputed, then anyone could recompute any other persons private keys.  Bitcoin would fail and so would essentially all other crypto.  PRNG while not truly random are designed to make such recomputation infeasible.  They don't just use a timestamp, they pull data from an entropy pool which is filled with sources like # of disk I/O failures in last x seconds,  random noise from sound card DAC, temperature of processor, the timing (in milliseconds) between keystrokes on the keyboard, the mouse movement data, the latency recorded on IDE calls.

To recompute a PRNG value would require not just the timestamp of the value but recreating the system in the exact same configuration as it was at the time the random value was requested.  This is nearly impossible unless there is some flaw in the PRNG and even then you would need some extensive cryptanalysis and a lot of computing power (i.e may take quadrillions of attempts to recompute the target value).

Of course it is also possible to generate private keys using a true hardware random number generator (quantum random number generator is one example).  For those there is no method, not even theoretical to recompute the generated number.

Ok, this makes perfect sense to me. Thanks.
So then I don't understand how to make a computation feasible.
If I am calculating right, when we use the whole network hashrate for one year we would have only 2^80.

PS: Just to recreate the lost coins with a hard fork would be like a reinventing of the current banking system. So I hope there will be never any significant majority for that.. (but I think this is hiiiighly unlikely)

In my opinion people need to take responsibility for their own actions. You deposited with Gox? You lose when they go under.

Anytime I send funds to an exchange, I understand that these are not dollars and are not backed or protected by anything or anyone.

It is a trust arrangement between me and the exchange, and we both serve to benefit from this relationship. But if I lose my coins, thats on me.

It called being a grown up, and not acting like a baby. I feel bad for those who lost on Gox, but its insane to argue they should have their coins restored because of their bad choices.

I made (what now look like) good choices, and didnt put any coins on Gox. If people who lost on Gox had their coins "reissued" that would radically devalue all existing coins and I would probably leave Bitcoin.

Many people have withdrawn their money since last June. The red flag was there for months. People staying there were either playing with fire, lazy, or simply ignorant.

Although that might be a good idea to regulate bitcoin exchange, that is irrelevant to the bitcoin as a currency or protocol. You don't need an exchange to spend or receive bitcoin.

Many people believed in bitcoin and got badly burnt. If you are suggesting that only sophisticated investors should use bitcoin, so be it.

Anyways, regulation can be enforced only by governments and in ways that they see fit. If regulation comes into the bitcoin world, I expect it to be intrusive and impose rules on the way bitcoin works. NB When I refer to the bitcoin model I don't mean just the intellectual and technical marvels of the bitcoin protocol, but to the way bitcoin plays out in the practice of people's lives, which IMO is what matters.

I'm gonna run with this, speaking for myself rather than the OP. I think that investors should be more sophisticated. I am not good at exchange games, therefore I play them very cautiously with a goal to learning. And I EXPECT to lose, thus I do not lose that which I cannot afford. I don't INTEND to lose, but I am a novice and I know it and act accordingly.

I think the moral hazard inherent in the funny money that has been foisted upon us since the early 20th century has made most of us complacent and unsophisticated in a manner that would perplex our ancestors to no end. I guarantee that when money was still golden, people were MUCH more circumspect with whom they trusted. And those so trusted earned it. Those who didn't quite often ended up on the wrong end of a rope or a gun. Hard consequence? Yes. Effective? Yes. It was and remains a good model. The fact that bitcoin functions on that same model is a STRENGTH of the concept, not a weakness. There is little moral hazard involved in the circulation of bitcoin, as it IS scarce, it IS irreversable, and it DOES require the individual actor to have a brain. I think this makes it superior to most other currencies. I don't think it superior to gold, but it does have some advantages even there. Mainly easy portability.

If you look at it from a market point of view, this is a good thing in the long run. It's a wake up call for the complacent, a loss of malinvestment, and a good chance for all bitcoiners to clean their own house. Exchanges are necessary, but they are now going to be under far more scrutiny FROM US than they were previously. Those who prove themselves will do well for us and for themselves. Those who try to cheat will have a much harder time of it, and the incompetent will either shape up or fail.

Bitcoin is not harmed by this event. Mtgox is slain and a lot of individuals are harmed. Bitcoin is strengthened, and the harm done to the poor bastards who lost their coin is not permanent. They made the money in the first place, and if they are competent they will overcome the setback. Doesn't make what Mtgox did right, but it does set a perspective.

Don't harm the blockchain to bail out a bad actor. It killed the dollar, and it will kill bitcoin.

Bitcoin works fine without a trusted third party.

Bitcoin users who refrained from trusting any third parties lost exactly zero bitcoins.

Bitcoin promises to let your "be your own bank". If you decide to be your own daytrader then you're on your own.

I agree. However it's a fact that an inordinately large number of people chose to entrust their bitcoins to an unreliable third party such as Mt.Gox. The resulting disaster and those that may follow along the same lines can be tackled either

a) by pointing out , not without reason, that this is a non-issue, since in the bitcoin world it's every man for himself. That's fine , but it may scare off the naive adopter, i.e. the vast majority of people, compromising bitcoin's success.

or

b)  by introducing regulation for exchanges, i.e. turning them into banks, transforming the current bitcoin model into something quite different.
Or c) Holding people accountable for their actions, and requiring a high level of thought, diligence, and TRANSPARENCY from those we choose to be custodians of our treasure. Prior to being owned by governments (or the reverse, if we're to be honest) banks were beholden to their customers FIRST. Those who failed in that ceased to exist.

Those of you seeing this as a failure of a free market system need to educate yourselves on how the "invisible hand" actually works. This is a failure of a sub par company, which is a SUCCESS for the free market. A bad actor has been removed. Not bailed out. Not being "too big to fail".

If their intent was good, they were too incompetent to be in the business they were in. If they were fraudulent, then they deserve to be caught, fleeced as much as possible, hung out to dry, and consigned to the dustbin of history as a fine example of how not to run a business. Free markets are self correcting, and as in the case of most things in life, Stupidity on any actor's part is often painful and frequently fatal. The lesson to be learned from that is not to be stupid.

Bitcoin does work without the need for a trusted third party.   That being said you can't by technology prohibit people from using a third party.  Satoshi never outlined a system which would prohibit voluntary association.  Sadly many people opts out of the trusted third party model by using MtGox.  Not just using them as a temporary exchange service (and yes even in a model which has no trusted third party there is a level of trust needed between consumer and merchant/service provider), but using them as a long term storage of coins.  In essence using them as a bank without insurance or oversight.  

MtGox is dead.  Bitcoin still functions.  I made transactions all week long and none of them failed or were delayed because of MtGox.  Bitcoin is a revolutionary technology and for many concepts like

Perhaps I'm just inherently paranoid, but I have never kept coins online since my beginning with bitcoin. They are stored in my wallet, on my computer, a couple CD's, some flash drives, etc. I hold the keys, and my password is ridiculously random and highly encrypted.

I have used online wallets as a temporary measure, such as exchanging them for fiat or 1 day portability, but never more than 24 hours and never my whole wad. I use banks in the fiat world because I have little choice, but in Bitcoin, what's the point?

This seemed obvious to me even before I looked into Mtgox. What I saw there, two years ago, was a company that was either no good with money or deliberately fraudulent. People tend to forgive the former, but frankly I have less contempt for the fraudulent! Being stupid at your PRIMARY business is just inexcusable. In either case, they deserved to fail. Their customers did not deserve to be bankrupted along with them, though they should have exercised better diligence given Gox's history.

Edit. Former for latter. Oops.

Believers in Bitcoin were not burnt.

Believers in MtGox were burnt.  The warnings were obvious to me 2 years ago.  By 6 months ago even a gadfly like the Winkelevii knew to get out of the way.

MPOE-PR said it best over a year ago.  MtGox must die for Bitcoin to move forward.

All this talk about regulation is a smokescreen for convincing the community to surrender to the vampire squid. Everybody pushing this line of shit can fuck off.

If the current Bitcoin model allows a guy like MK to wreak such havoc, then there's something wrong in the current Bitcoin model.

If the current fiat currency model allows you to destroy money by burning banknotes, then there's something wrong in the current fiat currency model.  Roll Eyes

Haha. Very funny.

"With the possibility of reversal, the need for trust spreads. Merchants must be wary of their customers, hassling them for more information than they would otherwise need. A certain percentage of fraud is accepted as unavoidable. These costs and payment uncertainties can be avoided in person by using physical currency, but no mechanism exists to make payments over a communications channel without a trusted party. What is needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party."

Bitcoin works perfectly without a trusted third party.  People chose to ignore that bitcoin does not need a trusted third party, and put their trust in a untrustworthy third party - MtGox. 

It has been said many, many times, but if you do not have your private keys, you do not own bitcoin. At best you have a ledger entry on someone's books saying that they owe you X BTC.  It is the difference between owning gold or owning GLD; or holding cash in your hand or holding an IOU for cash from someone.  This is not a bitcoin protocol problem, but a problem with an exchanges interface with bitcoin which they eff'd up royally.

Let's say that some cryptographic breakthroughs during the next few years allow us to figure out a private key from a bitcoin address in a reasonable amount of time (ie both SHA256 and RIPEMD160 become vulnerable).

By then, the bitcoin software will have been upgraded to work with a different set of hashes and everybody will have sent all their balance from the old, potentially compromised addresses to the new ones. This scenario would mean two things:

- We would be able to know the exact amount of lost coins. All balance that remains in the old addresses could be safely assumed to have been previously lost.
- All those lost coins could be reintroduced back into the system by cracking their private keys (I'll leave aside the subject of how to distribute them among users).

Now, if mtgox hasn't been robbed and the root cause of this situation is that MK lost the private key(s) to the cold wallet(s), we would have a chance to return the coins to their rightful owners without forking the network or minting new coins. We would just rescue those lost coins and put them in circulation again.

Full disclosure: I'm one affected mtgox user.

In such case one can also rob Satoshi's coins. Yes, you will get your bitcoins back, but they will be totally worthless.

I'm sorry about your loss, but the only owners of those BTC are the ones who presently hold them. There is not a shred of evidence that those coins are "lost", meaning those private keys are destroyed by MtGox. I know this sounds harsh, but any attempt to try to return those coins to previous owners by some technical method would totally destroy Bitcoin. It's the exact opposite of everything Bitcoin stands for. There are legal paths that affected people can turn to, trying to use any other means would bring the end of Bitcoin. It's not fair (as life often isn't), but those coins are someone else's now.

Speaking of legal means, it's unclear to me that it's so hard to find people who allegedly stole them through malleability. There are server logs with IP addresses, there are ton of personal data including email accounts, all those data can be accessed with court orders in almost any country of the world. I don't believe those criminals were that good they didn't leave a single piece of evidence behind them. That's your biggest hope to return those coins IMHO. I refuse to believe that all of them were stolen, someone calculated that in order to steal 750.000 BTC from june 2011 till now you have to steal them at a rate of 1000 BTC a day. There's almost 0 chance fraud of that size can possibly go unnoticed.

That subject is an easy one: Whomever cracks them, gets them. It couldnt be any other way, unless we start talking about "tainted coins" again.
