Bitcoin The Almighty Buck Technology

Nine of World's Biggest Banks Create Blockchain Partnership 93

Posted by Soulskill from the mining-their-own-business dept.
An anonymous reader writes: Nine major banks, including Barclays, Goldman Sachs, Credit Suisse, and JP Morgan have teamed up to bring Bitcoin's blockchain technology to financial markets. "Over the past year, interest in blockchain technology has grown rapidly. It has already attracted significant investment from many major banks, which reckon it could save them money by making their operations faster, more efficient and more transparent." Leaving aside the question of whether banks actually want to become more transparent, they're funding a firm dedicated to running tests on how data can be shared and collected through the blockchain. "The blockchain works as a huge, decentralized ledger of every bitcoin transaction ever made that is verified and shared by a global network of computers and therefore is virtually tamper-proof. ... The data that can be secured using the technology is not restricted to bitcoin transactions. Two parties could use it to exchange any other information, within minutes and with no need for a third party to verify it."

    The best feature of Bitcoin has been its use as a proving ground for blockchain technology. Now that it has survived several years of the intensive hacking attempts that a virtual currency would obviously be first to undergo, banks are starting to deem it ready to track other kinds of transactions.

      True, but extending the resilience of the BTC blockchain to privately controlled uses, ignores one key point...

      The current BTC mining network pushes 407.7 PH/s. The entire TOP500 supercomputer list can manage 363.3 PFLOPs/s. One hash takes 12697 FLOPs (officially - The exact number depends on how you calculate it, since hashing doesn't actually involve any floating point operations). That means we have approximately 14000x the computing power on this planet dedicated to Bitcoin mining as we do "real" supercomputing resources available.

      The Bitcoin network has such high resilience to attack because you would need more computing horsepower than it has to compromise it (and even that doesn't mean you can arbitrarily rewrite the past, just that you can force a fork in the blockchain that you control). Assuming some half-assed clone by a handful of companies would have anywhere near the same level of security ignores almost everything that makes Bitcoin so secure.

        Bitcoin mining has little to do with blockchain computations. The former needs vastly more computational resources than the latter. The security of the blockchain has nothing to do with "computing horsepower", and everything with its distributed nature.

          You need a 51% attack to "double-spend". When the cost of achieving a 51% is more than a king's ransom: that is security in a very real and meaningful way. If someone COULD tamper with the blockchain, they WOULD tamper with the blockchain because their is a HUGE monetary incentive to do so.

        Bitcoin uses secp256k1. It is barely secure today. It will likely fall in due course. That's a really stupid curve to use. That's why no one uses it for anything - except bitcoin.

    Razormind, Ethereum, Eris Industries et al have been working on decentralized systems for nearly two years now. Eris released their DApp server for exactly this usecase and are working in the States to spread word of the tech. Ethereum recently pulled into release mode, and their decentralized system for smart contracts is slowly gaining momentum. Razormind has been working on a Decentralized Operating System which is driven by blockchains.

    Let me guess: they want to copy Bitcoin but not everyone can participate (only approved banks). They want to copy bitcoin but not everyone can mine (only major banks). They want to copy bitcoin but not everyone can see all transactions (filter to your own transactions only?). Yeap, it will end up with a close system in a centralized database just like they have right now.

    Bitcoin is about losing control to anyone and open access.
    • - If not everyone can participate they will remove the consensus code and add some sort of centralized authentication.
    • - If not everyone can mine it they will again have some sort of centralized authentication.
    • - If they remove the mining entirely, the currency creation will be either pre-mined with some banks at start or distributed based on a some specific rule that will favor the big starting banks. Having no mining will also remove all incentive to validate the transaction, make the whole thing weak and prone to double spend attack.
    • - If they don't want everyone to see all the transactions, it will be close network with restricted access. A single bank could leaked out the entire blockchain, I'm not sure they really want to go in that direction!

      • The concept of mining was to bootstrap the currency. How do you start it? who have how many? The big bank all start with 1 billion? They transfert a real billion to who to get the virtual currency? If they transfer the real money in a "pot", that would be a system the ACH in USA. Someone do control the pot. This has nothing to do with a decentralised blockchain.

          Don't be silly. Mining was a side effect of the algorithmic design of bitcoin. For a completely new system the blocks could all be created in advance using random numbers and allocated on a need basis. If someone manages to guess an unreleased block and uses it then the police are called.

      They won't be using the blockchain as currency, only as a ledger. The coins won't represent actual money, but the capacity to write entries to the ledger. The incentive to validate transactions is they want transactions to be validated, not because the coins have direct monetary value.

    • Bitcoin's problem is that they artificially limited the maximum number of bitcoins to 21 million. That breaks one of the fundamental requirements for a true currency. The entire reason countries have moved off the gold standard is because for a currency to function, it has to grow at roughly the same rate as your economy.

        No, that's way off base. The size of the US money supply isn't increased by printing more slips of paper with presidents on them. The number of tangible (well, whatever you want to call a bitcoin) units of currency barely matters to the money supply.

        The size of the money supply is controlled by fractional reserve lending, and indirectly by insurance floats and credit derivative swaps (there are nearly $1 quadrillion in CDSs now). All of that would work with BTC, or gold, or USD with equal facility.
