Last Forking Warning For Bitcoin 334

ASDFnz writes "It has been just over two months since the bitcoin block chain was rocked by a near disastrous fork causing the bitcoin price to crash. The culprit of the crash was found to be a bug that prevented pre version 7.1 bitcoin clients accepting large blocks that could be generated by version 8 clients. A temporary fix was put into place by Bitcoin Project lead developer Gavin Andresen that forced version 8 clients to generate blocks that version 7.1 could understand. It is important to note though, the fix was a temporary one! In just under two days on the 15th of May the fix will expire and version 8 clients will once again be able to make large blocks that older clients will not be able to understand."

    Oh shit, the sky is falling.

    Total disaster, never happens in real world, not virtual one. Except for all the times when 'real world' currencies undergo devaluations, revaluations, forced exchanges, just plain old inflation, all the things that lead to currencies collapsing. I mean name me a paper currency that lasted longer than 80 years on this planet without a major restructuring, without collapsing?

    This is a technical problem, I am pretty certain it will be addressed. Not that I care much about Bitcoin in itself, but I like the idea of competing currencies and this is definitely a revolutionary one, so it's interesting to observe. I don't think it's going away any time soon even with technical issues.

        There is a pretty long list [wikipedia.org] actually of places with serious inflation in recent times. It's not unlikely that there are slashdot posters from those areas, who have indeed experienced a currency collapse or at least runaway inflation in their lifetime.

      However, other currencies don't have this problem where the currency just "breaks" suddenly, and basically stops working.

      Imagine if bitcoin had been more popular, if everyone had bitcoin applications on their phone which take months to get updated, where half the world if running v7 and half v8. This would have (as I understand it, and I think I do) just fundamentally broken bitcoin, possibly beyond reasonable repair.

I mean name me a paper currency that lasted longer than 80 years on this planet without a major restructuring, without collapsing?

      I agree that the dangers of bitcoin forking have been overstated, and are something of a manufactured drama - technical problems like this are not very difficult to surmount. The real problem with Bitcoin for me is that the system is not transparent, and nothing backs the currency (unlike those fiat ones you mention above).

      A currency is a token of trust (trust that others will value it the same amount), and that's a fragile thing.

      Bitcoin is currently a small curiosity, it's only just becoming big enough to attract the interest of the real sharks, and I'm not convinced the creators have the resources, motivation or interest to keep the currency fair and secure once serious money becomes involved. Many of the exchanges are still pitifully insecure (run on VPSs !), the infrastructure is not well managed (witness problem above), and the creators probably never expected it to take off or really thought through the implications. Once there is serious money involved, lots of people are going to want to change the rules. If Bitcoin becomes popular it will be easy to coopt, devalue, and tax until it is just another currency, probably tied to a particular corporation or government. There's absolutely nothing you can do about that as a user of bitcoin. If the developers decided to change the direction of the currency you have your life savings in, devalue it, create a new block chain, you don't even have a vote on the matter.

      Currently, if the government of your country or anyone else with the power to control the flow of bitcoins decide it should become valueless for you, or illegal, that can easily happen, if someone corners a significant supply of coins, they can manipulate the market (this is probably already happening as there are ZERO controls in place to stop it), if the public panics due to misinformation or rumour in such an illiquid market there is nothing to stop huge swings in value, and if a government decides to coopt the currency, shut down exchanges and change the rules by fiat, no-one is going to be able to trade in it and interest will evaporate. I see that as the largest problem with bitcoin by far - there are no backers putting up their own goods, no-one to trust, and no way to ensure that others continue to play by the same rules as they used to. It's certainly very appealing to utopian crypto-anarchists, but of limited interest to anyone who wants to store value or exchange it, given that it has the disadvantages of cash (anonymous, fungible) with none of the upsides (backed by a sovereign government, relatively stable, regulated to a greater or lesser extent, insurable etc), and a few downsides of its own (massively fluctuating value, built-in deflation, early-adopters privileged).

      Because it is untraceable, and not guaranteed by law, it's of no interest to the majority of people who use currencies to store and transfer value and receive payment. I *want* my transactions to be traceable, so that I can prove to gov. and counter-parties that I have fulfilled my part of a bargain, made a payment, and should receive goods or services in return. If I don't want a transaction to be traceable (very rare, but conceivable), I'd use barter or some kind, but a currency outwith the control of government holds little interest for me, *precisely because* it is outwith the control of all the rules of society I value. Those who've had their valuable bits stolen from some VPS have no come-back using bitcoin, and no way to find a thief or enforce punishment - I'd demand far better than that for any currency I put trust in.

        I don't think you know enough about Bitcoin, and I encourage you to read more about it. While it is hugely volatile, and even more hugely risky - not to say stupid - to "invest" in, I think many of your criticisms are invalid.

        Bitcoin is absolutely traceable - it's far more traceable than cash. Read up about how the blockchain works (and see the Zerocoin proposal to see how it could be made untraceable, optionally, in the future). (The only non-traceable coins are those minted by miners with very paranoid security arrangements).

        Cornering a "significant supply of coins" would take a significant investment of "real world" cash to actually corner these coins - not a trivial thing to get your hands on. So I don't think this is a large risk for the current Bitcoin ecosystem.

        Also, you suggest that with regard to an entity trying to coopt or alter Bitcoin, "there's absolutely nothing you can do about that as a user of bitcoin". That's not true - simply running the reference software implementation makes you a node in the network, thus enforcing your (i.e. the default software's) set of rules on the transactions you do/do not relay. And additionally, the computing power deployed by today's miners would probably be impossible to exceed except by a very determined and well financed attacker. How much would a government spend to attack Bitcoin?

        And if the "creators" (by which I suppose you mean the current set of core devs) try to create a new blockchain, good luck to them - the blockchain is far more resilient and the network runs as a democracy. It wouldn't work unless a vast amount of users also followed.

        Your point about exchanges is key of course - they are extremely amateur operations right now. But that's easily changeable by hard work.

        Digital cash ought to excite any geek - whether Bitcoin is "it", or simply an alpha version of something better yet to arrive, who knows.

      the whole argument for going thru the pain of adopting a new currency is that it's immune to the problems of the existing currencies. If it's going to have the same sort of problems, what's the point? Does it really matter to you whether the result of your currency being devalued is due to government policy or a bug?

        But the value of the gold probably bears little relation to what its intrinsically worth. I.e. if gold weren't being used as a currency of sorts, it wouldn't be as valuable since its uses would be relatively minor (jewelery, electronics, etc). In this respect its very much like a fiat currency - it has an inflated value because people believe they can sell it on for a high price.

        The "guarantee to pay" is a little bit meaningless here - I can't go to the government and tell them to exchange my bit of paper

        Generally no, only as payment for debts, products consumed or services already provided like eating at a restaurant and paying afterwards. Stores can refuse you for having too large money like $100 bills, too small money like tons of one cent coins or pretty much any reason they want. Having legal tender doesn't force anyone to do business with you.
