The Satoshi Nakamoto mystery deepens as Wright backtracks


It seemed that the founder of Bitcoin ha finally been discovered after an admittance by Australian Entrepreneur Craig Wright that he was Satoshi Nakamoto. But three days when the media tried to probe it further to confirm the claims Mr Wright has backtracked and apologized in his blog and claimed that he was not strong enough for this. This series of events has only made the matter more complex.

He wrote in a blog post that he does not “have the courage” to publish additional proof, as he promised Wednesday, that he is the elusive creator of the Internet currency.

Wright’s initial claims drew widespread skepticism. He said Wednesday that he would provide verifiable documentation and take additional steps to prove his identity. Instead, he scrubbed his blog clean of past entries and posted a short statement titled “I’m Sorry.”

Wright didn’t explicitly renounce his claim to have created bitcoin. He merely wrote Thursday that he thought he could “put the years of anonymity and hiding behind me.” But as this week’s events unfolded, he wrote, “I am not strong enough for this.”

“I can only say I’m sorry,” he wrote at the end of the post. “And goodbye.”

The search for Nakamoto has been a parlor game for journalists and online sleuths since he disappeared from online forums in late 2010. Wright claimed to be Nakamoto in interviews with the Economist, BBC, GQ and a few bitcoin insiders in stories published Monday. He bolstered it with technical demonstrations that two of those insiders vouched for, but failed to repeat those proofs in ways that would allow anyone else to verify them.

Skeptics reacted harshly to the public proof Wright did offer. For instance, he purported to sign a passage from Jean-Paul Sartre with one of Nakamoto’s private encryption keys. Experts argued he hadn’t done that at all, and instead had merely republished a snippet from a historical bitcoin transaction signed by the original Nakamoto.

Other posts Wright made following his revelation came under fire as well. One of his blog posts attacked a 2013 paper that described how the bitcoin system could be gamed by a group of insiders the paper called “selfish miners.” Some readers of the post said it showed a fundamental misunderstanding of the risks.

“Sadly, Craig did not get it,” said Emin Gun Sirer, a Cornell University computer science professor who co-authored the original paper. “It seemed like he failed to understand what the whole attack was about. That completely made me doubt his veracity.”

Some had argued that the identity of the founder shouldn’t matter. Bitcoin’s code has been updated many times since its founding and a debate over how to cope with a looming capacity problem will be resolved by bitcoin “miners” who keep the currency system running, not by the opinion of one person — even Nakamoto, whoever that might be
