Dorian Prentice Satoshi Nakamoto, the man named by the Newsweek magazine as the creator of Bitcoin earlier this week, has denied any involvement.
Satoshi Nakamoto, who changed his name to Dorian Prentice Satoshi Nakamoto in 1973, said he had not even heard of virtual currency Bitcoin until a few weeks ago.
He was singled out as the man who wrote the code underpinning Bitcoin by Newsweek.
But he said that quotes attributed to him that seemed to suggest his discontinued involvement with the project had been “misunderstood”.
“I got nothing to do with it,” Satoshi Nakamoto told a reporter on Thursday.
The man was identified as the “face behind Bitcoin” in a Newsweek article published this week. A reporter spent about two months investigating the claim and tracking him down.
When the reporter – flanked by two police officers – found the 64-year-old former physicist at his home in California and asked him if he was involved with Bitcoin, he is reported to have said: “I am no longer involved in that and I cannot discuss it.”
However, Dorian Prentice Satoshi Nakamoto told an Associated Press reporter on Thursday: “I’m saying I’m no longer in engineering, that’s it. And even if I was, when we get hired, you have to sign this document, contract, saying you will not reveal anything we divulge during and after employment. So that’s what I implied.
“It sounded like I was involved before with Bitcoin and looked like I’m not involved now. That’s not what I meant. I want to clarify that.”
Dorian Prentice Satoshi Nakamoto said he was born in Japan and moved to America in 1959 and that English was not his first language.
The value of Bitcoin has fluctuated as knowledge of and interest in what was until recently a little-known currency has increased. It is used to bypass financial institutions, making it attractive to people who want to trade directly. That has led to a level of adoption by speculative investors and some criminal enterprises.
This week, a Democratic Congressman is reported to have called for it to be banned. Jared Polis called the currency “unregulated and unstable”.
In 2012, a leaked FBI report showed that the agency was concerned that Bitcoin could become widely used by criminals.
The report said that the virtual currency was an “increasingly useful tool for various illegal activities beyond the cyber realm”.
In August 2013, it was announced that the “scale of the risk posed by” Bitcoin was to be investigated by the FBI on behalf of a US Senate committee.
The entity behind it has always been known as “Satoshi Nakamoto”, although it is unknown whether or not that is a pseudonym.
Dorian Prentice Satoshi Nakamoto insisted he had never heard of Gavin Andresen, a leading Bitcoin developer.
Gavin Andresen told Newsweek he had worked closely with the person or entity known as Satoshi Nakamoto in developing the system, but that they never met in person or spoke on the phone.
Dorian Prentice Satoshi Nakamoto told the AP that he would have had the technical ability to come up with Bitcoin.
He said: “Capability? Yes, but any programmer could do that.”
He also admitted that elements of the Newsweek story were correct. He said that he did once work for a defense contractor.
Dorian Prentice Satoshi Nakamoto added that he also worked on missile systems for the US Navy and Air Force and, consequently, it was necessary to keep many details of his work was confidential.
Newsweek reporter Leah McGrath Goodman, who spent two months researching the story, told the AP: “I stand completely by my exchange with Mr. Nakamoto. There was no confusion whatsoever about the context of our conversation – and his acknowledgment of his involvement in Bitcoin.”
