IBM and Linux Foundation To Create Blockchain For Major Financial Institutions (thestack.com)

An anonymous reader writes: Following initial news of the project in March, IBM, under the supervision of the Linux Foundation and in partnership with several major tech interests including Fujitsu, has announced today that it will lead development of a new blockchain — a financial transaction ledger fashioned after the Bitcoin model. Provisionally called Open Ledger, the new initiative is aimed specifically at financial transactions, and though it will be open source in terms of development, but 'semi-private' in operation. Those with an interest in the project are said to include JP Morgan, Wells Fargo and the Bank of England. IBM VP Jerry Cuomo, who has discussed the project with Fortune and Wired, commented "The current blockchain is a great design pattern...Now, how do we make that real for business? What are the key attributes needed to make that happen? That's what this organization is about."

      > Bitcoin is already real for business.

      Bitcoin is real for SOME businesses who operate online. It's not feasible for anyone else, and it is most DEFINITELY not feasible for everyone.

      There's just so MANY reasons why bitcoin has issues. I'll list a few, and maybe someone can pop in with more.

      1- Bitcoin transactions can take hours to complete, and in no cases do they complete fast. The global transactions per second possible is really low (like less than 20), compared to thousands for credit cards / etc. In *practice* the total transactions per second possible now is less than five.
      2- To speed up the transactions to even the theoretical max would require a bunch of random people to agree on standards, but with a low limit they find that people will "bribe" the system by enclosing a transaction fee into their transaction. This moves the transaction higher in the priority (because the processors stand to get some payment). That's not inherently awful, but it means that any time someone wants to speed stuff up for everyone, the people doing the processing stand to lose money- so, of course, they don't want this to happen.
      3- Everyone who touches this stuff seems to turn into some kind of thief. It's like dark magic. Feds bust DPR, one of them steals his shit. Mt Gox takes off with everyone's cash, or a hacker does, or who knows, the point is it is gone. It's all gone, every time. Put bitcoins in this jar, I have a plan. Oops, the plan was to take the jar.
      4- The people sound absolutely insane. I'm a libertarian, and they sound insane to me- imagine how all this screed sounds to someone who isn't even of that persuasion.
      5- A ton of bitcoin are locked up by the person or people who premined it, who may or may not be the businessman who got investigated, or who knows. The whole thing is shrouded in ludicrous amounts of secrecy.

      Bitcoin has a niche for now, but this is very volatile and backed by nothing except scarcity. It exists solely because there's no good way to transfer money anonymously without meeting in person- literally any government in the world could tank the price by offering a way to transfer their currency anonymously.

      So it's a currency that takes a premium above the market share to buy, takes a premium to trade with, takes minutes at BEST to confirm a transaction, usually involves a transaction hit on the sell, and involves a fee to pay to the miners on any transaction- and everyone involved at the high level is both fully invested and fully delusional. Oh, and the price is ludicrously volatile. And everyone who you trust immediately turns into bats and flies away.

      In almost every case someone is basically trying to take the form of a bank. In the fiat system all the money is given to the banks (literally, it's created digitally on demand at lower interest than treasury bills, which can then be deposited in the bank allowing the bank to borrow 20x their value, buy tbills with it, deposit, rinse and repeat). You don't need a bank. No deposits, no having your deposits being ripped off. The problem is the transition period. I've got no fix for that one.

      "5- A ton of bitcoin are locked up by the person or people who premined it, who may or may not be the businessman who got investigated, or who knows. The whole thing is shrouded in ludicrous amounts of secrecy."

      This is the one I hate hearing the most. At it's peak it was like $200 million bucks worth. So what? Look what zuckerberg got for making facebook. He also is still sitting on most of it (okay he's about to give most of it to charity but pick another, bill gates, steve jobs, etc most of them still have the majority of their stock counting on their business growing and the value going up). Why shouldn't the creator of the system and the early adopters (early investors) make more. Bitcoin operates in a circular fashion as a unit of value in proper exchange for goods and services. It is not a ponzi or pyramid. This is a hell of a lot more reasonable than the current fiat system which mathematically depends on generating inflation and then automatically gives all the new inflation to people in the top 0.001%.

      "and backed by nothing except scarcity"

      Wrong. Scarcity is not bitcoins value. Bitcoins value is that it is currently the only commodity which is impossible to counterfeit. There is not a single .00000000001 BTC worth of fake bitcoin, anywhere, ever. No government can say that about their currency. If they can make it, and do so cheaply enough to make it viable, someone else can produce it as well. Combine that with scarcity and you have not only the perfect value holding unit but something governments can use to exchange with each other. No longer would the US have to trust that China would under value their currency to gain a trade advantage. No longer could new zealand produce almost nothing of value with a tiny population but live like a thriving highly productive western nation. Bitcoin COULD be made inflationary (although once a currency can divide to arbitrary decimal places it mathematically functions the same as an inflationary currency, you just end up trading smaller bits rather than larger quantities and no longer need to figure out who to give the money to). But the system to determine more units were needed in circulation would need to also be a distributed peer system that works automatically based on math. The average transaction size goes below x, add to the blockchain and if 60% of clients agree the extended blockchain is valid the extension is valid.

      "takes a premium to trade with"

      This is true of all digitial currencies. Even with regular fiat currencies, cash transactions have a premium because they have a minimum unit size and fractions get shaved.

      "Oh, and the price is ludicrously volatile."

      True but that is primarily a problem of scale. If the bitcoin market were the size of a major nations economy it would be just as stable if not more so.

      Several years ago sure. Typically minutes with todays hashing rate.

      Hashing rate has zero effect on how quickly transactions are confirmed in the blockchain. The network adjusts the difficulty to counter increases in hash rate such that one block is completed, on average, every ten minutes. This is an important part of maintaining coherency: blocks need to be propagated to (almost) every node across the network in significantly less time than the inter-block interval. If blocks occur too quickly then you get lots of forks and have to wait for more confirmations before you can be sure the transaction is properly recorded, negating any speed gains.

      A better counter-argument would be that the GP is comparing apples and oranges. With Bitcoin, once you have a couple of confirmations (on the order of 30 minutes) the transaction is effectively irreversible. To reach that point with any other online payment system requires months. If you don't care about reversibility, Bitcoin transactions are generally visible to the recipient, with 0 confirmations, within a couple of seconds after they're broadcast. At that point the recipient can see that the transaction exists and is (currently) valid, though with a lot of work and some luck it may be possible for the sender to preempt it with another conflicting transaction before it's officially recorded in the blockchain.

That's settlement: once on the blockchain the transaction is irreversible.

At that point you have two factors protecting the chain from forking: the technical CPU power requirements, and the already present "good behavior" of the banks themselves, who don't want to get kicked out of the cartel for shenanigans. That could also reduce the CPU requirements a lot - the members of the cartel can simply decree that nobody seeks to acquire more than N% of the total processing power or they get kicked out. No need for a continuous race to stay relevant, just a little good old-fashioned collusion to keep CPU requirements artificially low.

      Imagine changing the system to extend the block chain (with the transactions voted on by consensus the same as regular bitcoin transactions) and the extensions triggered automatically when the average transaction gets too small. Now each major national bank operating as large a mining operation as their nation can afford.

      You now have a global currency with no nation having to trust another to value it's currency, they instead build the biggest farms they can and increase the transaction processing power at the same time. No more china cheating on the value of their currency or hidden us inflation. No more nations having to use US currency to buy oil or trust a nation to value it's currency appropriately and off debts between nations in money the debtor can simply print.

      Sure, but the reason the block chain works for Bitcoin is that it has an omniscient view of all transactions ever and can prove whether or not you have "money" in your account. Unless every US dollar and all shares of the stock you're trading in is traded through this system, you'll always have clearance risk that whoever is claiming to sell you stock doesn't have it and the one claiming to buy your stock can't pay. Recording the promised transaction is really not that complicated, stock exchanges act as a neutral third party and do that for millions of trades each day. The risk is that the trade will never be completed as recorded.

There is no need for "mining" when only trusted peers are allowed to contribute blocks—any peer can just append a block and broadcast it to the rest, with some simple arbitration protocol to resolve race conditions. You would still get the primary characteristics of a blockchain, a Merkle tree of ordered transactions protected by a chain of signatures stretching back to a genesis block.

      The whole point of "mining" in Bitcoin, besides providing a reasonably fair initial distribution of bitcoins, is to avoid the need to trust the other nodes or employ some out-of-band protocol to deal with forks, whether due to races or malice. The more CPU-efficient solution which would be viable for a (semi-)private blockchain with write access restricted to trusted insiders would be utterly impractical as the foundation of an open, decentralized network of anonymous (or pseudonymous) users.
