Nine of World's Biggest Banks Create Blockchain Partnership 93
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.

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.

I'm sorry but you are 100% wrong. The security has EVERYTHING to do with the computing horsepower, the distributed nature is what makes it robust.
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.

Nope, the blockchain is tamper proof because:

Check out the finding on fields of low characteristic presented to EuroCrypt in January. secp256k1 uses a binary curve, so the characteristic is 2.

Ok, lets do it in crayon. The idea of mining is to discover a valid block. This is done by using an SHA based matching algorithm which - eventually - will find a valid new block.

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. Gold didn't, and every time economic growth outstripped the rate new gold was mined, the currency deflated (gold became worth more).
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.
