Craig Wright, an Australian businessman, said he is Satoshi Nakamoto, the shadowy creator of the shadowy virtual currency known as bitcoin.
Wright, a computer scientist and engineer who has been the subject of increasing speculation regarding bitcoin’s origin, made the claim in a posting on his website and in interviews with the BBC, The Economist and GQ Magazine, the Wall Street Journal reports.
The revelation shook up the bitcoin world, triggering debates on whether the 45-year-old entrepreneur’s claim is true, the newspaper said.
Those who doubt his claim note that what Wright has produced publicly isn’t irrefutable and what irrefutable evidence he does purportedly have was shown only to a few people.
“Some people will believe. Some people won’t. And to tell you the truth, I don’t really care,” Wright said in a video posted on the BBC’s website.
“I was the main part of it. Other people helped me.”
Gavin Andresen, another of bitcoin’s core developers who worked closely with Nakamoto in bitcoin’s early days, said on Monday he believes Wright is the cryptocurrency’s inventor.
“After spending time with him I am convinced beyond a reasonable doubt: Craig Wright is Satoshi,” he wrote in a blog post.
Bitcoin Foundation founding director Jon Matonis also met with Wright and said he believes Wright’s claims.
The currency is now estimated to be worth more than US$6 billion, the report said.
