Controversy is surrounding claims by Newsweek to have found the creator of the Bitcoin virtual currency.
It was assumed that the name behind Bitcoin, Satoshi Nakamoto, was a pseudonym for the group of coders who developed the system.
Now Newsweek claims Dorian S Nakamoto, a 64-year-old model train enthusiast who lives on the outskirts of Los Angeles, is the creator.
But he has denied his involvement saying: "I have nothing to do with Bitcoin".
