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."
