LOS ANGELES (CBS/AP) — Dorian Prentice Satoshi Nakamoto denied Thursday that he is the creator of bitcoin.
Newsweek published a 4,500-word cover story claiming Nakamoto is the person who wrote the computer code underpinnings of bitcoin, but in an exclusive two-hour interview with The Associated Press, Nakamoto denied he had anything to do with the digital currency.
Nakamoto, 64, said he had never heard of bitcoin until his son told him he had been contacted by a Newsweek reporter three weeks ago. He acknowledged that many of the details in Newsweek’s report are correct, including that he once worked for a defense contractor, and that his given name at birth was Satoshi. But he strongly disputed the magazine’s assertion that he is “the face behind bitcoin.”
“I got nothing to do with it,” he said, repeatedly.
KCAL9’s Dave Bryan spoke with Nakamoto outside of his home in Temple City, where media from around the world were camped out Thursday.
Nakamoto, after walking to the KCAL9 News van, reiterated that he is the wrong guy.
“I have nothing to do with bitcoin. I never worked for the company. I don’t know any people there. I never had a contract there or anything like that. I wasn’t even aware of the product,” he said.
Nakamoto did not deny his past work as an engineer, and confirmed he would have been capable of understanding the computer code necessary to built such a project. But he insisted he’s not responsible for coding the currency.
“If I say yes, I could get in trouble. Alright? So, I’ll say no. Alright? I was an engineer before but that was many years ago,” he said.
“I never created a code. I never created a concept. I just believed that somebody – it could have been designed this way, to put my name in there. Satoshi Nakamoto is not that common [of a] name. But it’s not uncommon,” he continued.
Nakamoto said that at the time bitcoin was founded, around 2001, he was working as a government contractor, not working on bitcoin.
Newsweek stands by its story.
The journalist who wrote the article, Leah McGrath Goodman, released the following statement: “I stand 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.”
Goodman also explained her interest in the story to KCAL9.
“When somebody invents something that shapes the world, to want to know who he is and where he came from and what informed his invention is natural. I mean, it’s definitely natural to me and I hope no one sees that as an act of hostility,” she said.
The Newsweek article kicked off the relaunch of its print edition after 15 months and reorganization under new ownership.
Since bitcoin’s birth in 2009, the currency’s creator has remained a mystery. The person — or people — behind the digital currency’s inception have been known only as “Satoshi Nakamoto,” which many observers believed to be a pseudonym.
Bitcoin has become increasingly popular among tech enthusiasts, libertarians and risk-seeking investors because it allows people to make one-to-one transactions, buy goods and services and exchange money across borders without involving banks, credit card issuers or other third parties. Criminals like bitcoin for the same reasons.
For various technical reasons, it’s hard to know just how many people worldwide own bitcoins, but the currency attracted outsize media attention and the fascination of millions as an increasing number of large retailers such as Overstock.com began to accept it.
Speculative investors have jumped into the bitcoin fray, too, sending the currency’s value fluctuating wildly in recent months. In December, the value of a single bitcoin hit an all-time high of $1,200. It was around $665 on Thursday, according to the website bitcoincharts.com.
After Newsweek posted the story on its website early Thursday, Nakamoto said his home was bombarded by phone calls. By mid-morning, a dozen reporters were waiting outside his modest two-story home. He emerged shortly after noon saying he wanted to speak with one reporter only and asked for a “free lunch.”
During a car ride and then later over sushi lunch at the AP bureau in downtown Los Angeles, Nakamoto spoke at length about his life, career and family, addressing many of the assertions in Newsweek’s piece.
He also said a key portion of the piece — where he is quoted telling the reporter on his doorstep before two police officers, “I am no longer involved in that and I cannot discuss it” — was misunderstood.
Nakamoto told AP he is a native of Beppu, Japan who came to the U.S. when he was 10. He speaks both English and Japanese, but his English isn’t flawless. Asked if he said the quote, Nakamoto responded, “no.”
“I’m saying I’m no longer in engineering. That’s it,” he said of the exchange. “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,” he said.
Several times during the interview with AP, Nakamoto mistakenly referred to the currency as “Bitcom.” When shown the original bitcoin proposal that Newsweek linked to in its story, Nakamoto said he didn’t write it, and said the email address in the document wasn’t his.
“Peer-to-peer can be anything,” he said. “That’s just a matter of address. What the hell? It doesn’t make sense to me.”
Asked if he was technically able to come up with the idea for bitcoin, Nakamoto responded: “Capability? Yes, but any programmer could do that.”
The nearest Nakamoto has come to working on a financial system, he said, was a project for Citibank with a company called Quotron, which provided real-time stock prices to brokerage firms. Nakamoto said he worked on the software side for about four years starting in 1987.
“That had nothing to do with skipping financial institutions,” he said.
Nakamoto again said he believes someone either came up with the name or specifically targeted him to be the fall guy for the currency’s creation.
He also said he doesn’t discuss his career because in many cases, his work was confidential. When he was employed by Hughes Aircraft starting around 1973, he worked on missile systems for the U.S. Navy and Air Force.
He said he also worked for the Federal Aviation Administration starting around 1999, but was laid off following the Sept. 11, 2001 attacks.
Getting hired by a military contractor was the reason he applied for and received American citizenship. He decided around that time to change his name, adding “Dorian Prentice” to Satoshi Nakamoto, partly to sound more Western. He said he picked “Dorian” because he says it meant “a man of simplicity” and referred to the ancient Greek people. “Prentice” alluded to his affinity for learning, he said.
As he poured over the Newsweek story with a reporter, Nakamoto repeatedly said “oh jeez,” as he read private details about himself, quotes from his children and even specifics from his medical history.
“How long is this media hoopla going to last?” he asked.
