The future is blockchain, which already underpins digital currency

I AM no Dr Emmet Brown, but I have seen the future.

It has been 30 years since Back to the Future captured the imagination of a generation. Everyone wanted a Delorean Flux Capacitor, which transported Emmet and Marty comfortably to the future. And when Emmet said "unfortunately the car will never fly again", no one questioned the logic. Brilliant stuff.

Who would have thought a few years ago that the Commonwealth Bank would be a technology company delivering banking services? Its announcement that it will use crypto currencies and the blockchain technology is forward looking and, as Chanticleer said, "it is just the tip of the iceberg".
