Australian says he is bitcoin's long-sought creator

Australian tech entrepreneur Craig Wright has said he was the creator of the controversial digital currency bitcoin, after years of speculation about the long-sought person who has gone by the name of Satoshi Nakamoto.

The BBC reported on Monday that Wright gave some technical proof demonstrating that he had access to blocks of bitcoins known to have been created by bitcoin's originator.

But he declined requests from The Economist to provide further proof that he is Nakamoto.
