This week in Bitcoin: Is Satoshi Nakamoto really Satoshi Nakamoto?

In this week’s Bitcoin review,  we examine the (possible) unmasking of Bitcoin’s creator and the effect that the MtGox disaster is having on cryptocurrency worldwide.

Was Newsweek wrong?

On Thursday morning, Newsweek published an article that appeared to solve the mystery of Bitcoin’s elusive creator. His name really was Satoshi Nakamoto, although he had changed it legally to Dorian Prentice Satoshi Nakamoto, and he was a 64-year-old Japanese American who lived humbly in a house in Temple City, Cal. and collected model trains.

However, the backlash and doubt about the piece was swift. While some praised it as brilliant journalism, many questioned why a man who had been so careful to hide his identity and create an anonymous network didn’t use a pseudonym at all. Others were furious at Newsweek for “doxxing” or outing the life of a man who wanted to stay private.

After lunch with an AP reporter chosen at random and a “car chase”  to the AP’s downtown Los Angeles bureau, Nakamoto  gave the outlet an exclusive two-hour interview in which he denied creating Bitcoin, even reportedly calling it “Bitcom” throughout the interview. (The AP has posted the video of the interview here).

The story took an even weirder turn Thursday night when the original Satoshi Nakamoto posted in the same forum where he announced Bitcoin in 2009 “I am not Dorian Nakamoto.”

So now we’re back at square one.

Newsweek continues to stand by and defend its story. Dorian Nakamoto and the original Nakamoto online both say Newsweek has the wrong guy. Felix Salmon at Reuters summed it up nicely Friday: “Call it the Satoshi Paradox: the probability that Dorian is Satoshi would seem to be very small, and the the probability that Dorian is not Satoshi would seem to be just as small — and yet, somehow, when you add the two probabilities together, the total needs to come to something close to 100%.”

There’s no definitive proof that Dorian isn’t Nakamoto. There’s also no definitive proof that he is Nakamoto. And that’s where the Newsweek story erred.

How is the market reacting?

The price of Bitcoin continues to rise following the MtGox collapse even as Japan mulls over possible regulation and taxation of the digital currency. Federal Reserve Chair Janet Yellen said Monday though that the Reserve can’t regulate it in the U.S. because it exists entirely outside of the banking agency.

Bitcoin price jumped midweek and has hovered around $650 since then.

  • The Lakota Nation adopted MazaCoin, a cousin to Bitcoin, as its official currency.
