An anonymous reader quotes a report from Reuters: A former Google engineer, whose speech recognition software is used in more than a billion Android smartphones, has launched a company that uses blockchain technology to build a new operating system for banks. Paul Taylor, a Cambridge University academic with an expertise in artificial intelligence, speech synthesis and machine learning, started working on the system, called Vault OS, two years ago in a basement in London's Shoreditch district, known for being a tech start-up hub. The technology, which underpins the digital currency bitcoin, creates a shared database in which participants can trace every transaction ever made. The ledger is tamper-proof and transparent, meaning that transactions can be processed without the need for third-party verification. The system also negates the need for costly in-house data centers, as it uses cloud-based systems, which banks can use on a "pay-as-you-go" basis, which means that there is no single point of failure. Taylor said major high-street banks were spending around a billion pounds ($1.3 billion) a year on computer technology, much of which he said was being used for propping up the current "legacy" systems rather than on any innovative technology. The start-up has been working with about ten banks, Taylor said, at least one of which would be starting a trial using the new system in August. He expects the system to be up-and-running within about a year. In banking-related news, a Congressional report shows that China's spies hacked into computers at the Federal Deposit Insurance Corporation (FDIC) from 2010 until 2013 and American government officials tried to cover it up.
