Bitcoin Splits in Two Amid Feud (cnet.com)

Bitcoin is dividing in two. Disagreements about how to operate the cryptocurrency have led to a new strand called Bitcoin Cash, which is breaking off from the bitcoin system. From a report: Bitcoin Cash launches Tuesday in what is known as a "hard fork" from bitcoin, a virtual currency based on peer-to-peer transactions without any central authority or bank behind it. The new offshoot is a response to the increasing popularity of bitcoin, which is struggling to deal with massive numbers of transactions with its underpinning technology. The main bitcoin currency is adopting a system called Segwit2x that moves transactions out of the current blockchain, while bitcoin Cash will use bigger blocks within the blockchain. Bitcoin holders are set to receive the same amount of bitcoin cash as they have in bitcoin if the exchanges and wallets they use support the new coin, another report added. Exchanges including Kraken and ViaBTC have said they'll support both, while others like Coinbase and Poloniex have said they won't, citing uncertainty that bitcoin cash will have lasting market value.

      You assume wrong. Blockstream, Inc, a company financed by the second largest mainstream financial company (AXA), hired most of bitcoin's core developers, and drove off many of the rest. They have roadblocked bitcoin's expansion in order to force transactions "off-chain" onto private settlement networks, the kind that AXA can collect fees off of.

      A "block" is a set of bitcoin transactions secured with a cryptographic hash, so you can verify the contents are correct. Until now, the block size limit has been 1 MB. Since blocks are generated every ten minutes on average, this works out to slightly less than old 14.4K telephone modem speed. This is an absurdly low limit on transaction rate, but was not a problem until last fall, when the volume of transactions hit that limit. The core developers had refused to raise the limit, so that instigated the software fork.

      Bitcoin is open-source software, so it can be forked like any other OSS project. The split happening today is a simple change to the code, to allow up to 8 MB blocks. That amounts to 107 kbps, which is still well within modern broadband capacity. All the transaction up to this point is identical for both forks, but once the new fork generates a block > 1 MB, the other fork won't recognize it as valid. From that point forward their blockhains will have different histories. Any bitcoins you had previously will be represented on both ledgers, and it is up to the user to choose which software they want to use to handle future transactions.

      My understanding is that as of now the coins are separate, you have one on ledger A and one on ledger B and never the twain shall meet. The actual value of each will now be determined by market forces, so if they were viewed as equal the value of one would be roughly half, though it sounds like BTC has the leg up for now. I think the fact that many bitcoins will not be duplicated into bitcoin cash, due to their exchanges not supporting the new currency, is part of this.

      As a side note, an unscrupulous exchange could use this to undertake massive fraud, simply by announcing they would not support the fork while keeping their customers forked currency for themselves.

      The simple solution is for Bitcoin to halve in exchange value, relative to fiat currencies. then you can double spend, but get similar value.

      The real question is if double spending happens, and the fork is rejoined, what then? I don't think the fork can be rolled back or 'unforked'.

      Probably the hard fork will result in one chain attracting most of the volume, the other losing acceptance, and one survives.

      The Etherium 'The DAO' hack took place because some people uploaded experimental, poorly written solidity to the Ethereum blockchain. They didn't correct their coding mistakes in the time between creating The DAO (30 April 2016) and people putting $150M into The DAO (June 17, 2016), and by then the funds were an incentive for smart people to write better code to transfer the funds to a new DAO.

      Writing code to transfer funds from one DAO to another is not fraud. Fraud is wrongful or criminal deception intended to result in financial or personal gain. There was no deception here. Just clever code that was able to transfer Etherium because sloppy programming did not prevent the transfer.

      Am being pedantic because the whole point of Solidity contracts are that they will run no matter what. So if you are planning to let those contracts control substantial funds then you have to write them properly. Just like instructing a magical Genie to carry out your 3 wishes, you must be careful to be specific, because that Genie will perversely 'misinterpret' your wishes.

    Not really like a split. More like a clone. This doesn't happen in the stock or currency world. Basically you now have two chains that operate on the same history but are now divergent.

    I have no idea how the value of this will play out because it will depend on how strong the support is for each. If each gains equal support, I imagine a decline in valuation for both back to "normal". Otherwise you'll have one absorb the transaction space of the other and essentially just eliminate the loser's value overnight, probably. Depending on how long that plays out people are going to be trading on both which means potential volatility.

This need is most fervently expressed by privacy advocates, but lets be real: a huge amount of bitcoin's actual transactions are sketchy, and at least a decent number are outright criminal.

    So many things about Bitcoin should ring alarm bells. The fact that there's huge amounts of the blocks that have been mined and never moved. The fact that it's set up to be almost mined completely out not merely in our lifetimes, but reasonably soon (unlike, for instance, a precious metal- 70% of all possible bitcoins have already been mined). The fact that there's numerous vulnerabilities if enough of the network is under control of a bad actor. The fact that it markets so heavily to principle-driven libertarian types with an anarchist or minarchist mindset. The fact that the bulk of the mining is taking place in China, specifically where electricity is cheap, and is controlled by a few shadowy men. It's a a goddamned parade of red flags.

    And yet, there's still a desire to subscribe to suicidegirls without your wife finding out, and there's still a desire to get weed mailed to you or whatever.

    The underlying value is an economic concept called "utility". People value food and houses because they are useful to us. Their "utility value" is what other things we are willing to trade for them (our labor, dollars, etc). The thing is, utility value varies per person and even for the same person at different times. If enough trades happen over a period of time, we can establish an average "market value" - what people are currently willing to trade for this item.

    The usefulness of Bitcoin is in transferring economic value from place to place. Since it runs on the Internet, and is open-source software, it can do this function anywhere, for anyone. It is especially useful in circumstances where other methods (bank wires, credit cards, Western Union) are expensive or not available at all.

Now if one fork gains more traction than the other that fork will become more valuable. My bet is on bitcoin cash because it is more useful for me.
