As recently as , the estimated value of a single bitcoin was less than a penny. Now, one bitcoin is worth thousands of dollars. On the other side of the coin, the fact that cryptocurrency transactions are irreversible makes investing in cryptocurrency a potentially perilous endeavor. The largest crypto exchanges— virtual marketplaces that traders use to buy and sell cryptocoins— contain vast amounts of digital cash.

This One MtGox Creditor Might Recover $61 Million Dollars

That interface is made up of the exchanges that let you trade regular money into and out of Bitcoinage. June May September March Online gaming company ESEA illegally snuck Bitcoin mining code into its software — ironically in its anti-cheating module. August A flaw in the Java pseudorandom number generator allegedly led to Bitcoin thefts from improperly-secured digital wallets on the Android platform.

November Remember, you don't have to keep your Bitcoins online with someone else: you can store your Bitcoins yourself, encrypted and offline. If seems that you posted lots of withdrawals at the same time, and each one on its own would not have put you into the red, then the system would queue them all up and process the lot. Only when the dust settled would Poloniex realise it had paid out your last few dollars over and over again.

To be fair to Bitcoin fans, many of these problems have had little to do with the Bitcoin cryptographic infrastructure. Transactions, which have a one-off ID, are cryptographically hashed to mark them uniquely, but this hash is improperly computed.

The same ID can end up with two different hashes — one transaction being real, and the other being fake. The Bitcoin community, in a rather splendid euphemism, calls this transaction malleability , but you can call it a cryptographic flaw. Crooked transactors can use a deliberately created duplicate-yet-different transaction to trick naive exchanges into thinking that something has gone wrong, and demand a refund.

Smart exchanges use additional checks to help repudiate bogus transaction repudiations. Recent trading values suggest it will, though you can expect traditional financial regulators and anti-money-laundering investigators to have some very keen questions right now. Follow NakedSecurity on Twitter for the latest computer security news. If I send you a cryptographically secure email, and then send it again, the message will be the same, but the email headers could be different because of timestamp, routing and such.

As long as the fields protected by the hash are clearly described, which they are, it is a wallet or exchange bug or poor decision. A history of the bugs and fixes in bitcoin are much more subtle, like conflicts between the X. And the one big bug is that secure transaction confirmation with bitcoin takes too long, so companies come up with shortcuts and lose. There is a reason banks put a hold on checks. Regardless of the Magic CryptoDust in Bitcoin itself. The liberal parsing by OpenSSL is not, strictly speaking, incorrect.

It simply allows signatures in multiple formats, where only one is expected. The signature itself, and the data to be signed, cannot be altered, but by representing semantically identical data in a different format, the hash can be changed. This is not a flaw in the underlying cryptography, but an unintended but foreseeable and indeed well-known property of its application. I see your point that it is not strictly a flaw in the underlying crypto algorithm in contrast to the hole in WEP, for instance, caused by the inherent non-randomness of the cipher itself.

Bitcoins have nothing backing them except for the faith of the people who hold and want them. If everyone loses faith in them, their value will go to zero. Soooo, have you also stopped using the US Dollar? Also, a huge and time-tested regulatory and legal system to prosecute larceny, counterfeiting etc.

I forget, does Bitcoin have any of that? Plus manufacturing, administration and even a bunch of no-good politicians just like everywhere else! For that matter, gold has no intrinsic value beyond what people place on it. The entire concept of money is just a representation of an arbitrary value. The fact that representation is stored as encrypted bits which is what your bank does as well or printed on paper makes no difference.

Some 11 nuclear powered aircraft carriers, over nuclear submarines, hundreds of stealth fighter jets and bombers, thousands of Abrams battle tanks and such helicopters that killed UBL.

There is also a place called Fort Knox. All in all, much more impressive then the Bitcoin posse, who can, at best, throw cypherpunk sci-fi books at the skeptics…. It is not the gold in the vault very little there , not the military force being destroyed by poor policy , but the vastness of the underlying economy, in which people around the world are willing to invest, especially if the government cuts back on taxes or regulations.

If demand for my finished product vanishes, some value remains to be recovered in liquidation. Now lets say I have a whizbang software company in a rented building, with leased furniture and computers, and the fanciest social media system since faceplant or tweeter. My stock price is held aloft by the slim but growing advertising revenue, and the faith that my user base will soon outpace those other fuddy-duddies. Then one day, I have a major security incident, the users flee in droves, the advertisers have no reason to stay, and the business runs out of cash as the stock price is cratering.

Bitcoin most closely resembles the latter scenario, because, regardless of its inherent non-inflationary nature, it has no underlying value except for its desirability as a medium of exchange — cause doubt in its reliability, and the users will flee in droves, the miners will take their computing power elsewhere, and the blockchain will lose first its speed and then its integrity.

In other words, and I believe the malleability issue can be first worked around extra checks and then cured, BitCoin may be a great payments system, but it is not a commodity, not a business investment. Might as well be exchanging virtual tulip bouquets! Who stands to lose the most from wider adoption of bitcoin? Who stands to gain the most from a bitcoin collapse?

You know, a year ago, most of us would have blasted anyone who claimed the NSA was recording all telephone calls and collecting GPS data from mobile phones. Then one day everything changed. Oh, also advertise that your shed new shed! So where did the missing bitcoins go? What better way to kill bitcoin than you cause users to lose faith in its value and security. The Russians saw it as a clear threat, as do the Chinese, and the U.

Where did the bitcoins go? They were probably nicked, simple as that. Somebody saw a whopping great pile of money in an inadequately secured online shed, broke in, swiped the loot and scarpered. This had to be done by design. A hash is not a unique identifier or a primary key and should not be used as one. It does not. MtGox made an implicit assumption in their implementation that transaction IDs were constants, whereas there is no basis upon which to make that assumption.

The specification certainly makes no mention of using transaction IDs in the blockchain as verification of bitcoin transfers. Borrowing from two previous imperfect analogies, calling this a flaw of the specification is like saying that my car is flawed because it can be driven off a cliff. Comparing Bitcoins to dollars is funny. Try printing your own US dollars and see where it gets you! If it had been funded by investors from the start then it would be more credible.

But the greed of having computers print mine you free money is something many could not resist. Why should they? Like trying to trace a virus author, they can reap the benefits and not risk any blame. When Bitcoin crashes, you will just have a lot of pissed-off people hunting down all those who made money from it.

Since its inception in , the grand ambition of the Bitcoin project has been to support direct monetary transactions among a network of peers, by creating a decentralised payment system that does not rely on any intermediaries. Its goal is to eliminate the need for trusted third parties, particularly central banks and governmental institutions, which are prone to corruption. Recently, the community of developers, investors and users of Bitcoin has experienced what can be regarded as an important governance crisis — a situation whereby diverging interests have run the risk of putting the whole project in jeopardy. This governance crisis is revealing of the limitations of excessive reliance on technological tools to solve issues of social coordination and economic exchange.

Bitcoin is a cryptocurrency , a digital asset designed to work as a store of value that uses cryptography to control its creation and management, rather than relying on central authorities. Over the course of bitcoin's history, it has undergone rapid growth to become a significant store of value both on- and offline. From the mids, some businesses began accepting bitcoin in addition to traditional currencies. Prior to the release of bitcoin, there were a number of digital cash technologies starting with the issuer based ecash protocols of David Chaum and Stefan Brands. The idea was independently rediscovered by Adam Back who developed hashcash , a proof-of-work scheme for spam control in

Problem is I can't remember which exchange I used. Does anyone have a list of UK exchanges that were around in either or that might jog my memory?
