The 45-year-old's revelation has sparked debate around his claim to the identity of Satoshi Nakamoto, the mysterious figure who launched bitcoin in 2009.
The Brisbane-born tech entrepreneur told the BBC, The Economist and GQ on Monday he was Mr Nakamoto and provided proof of coin transactions and a digital signature which he said was held only by the bitcoin founder.
Bitcoin Foundation director Gavin Andresen, who took over the project when Mr Nakamoto disappeared in 2011, vouched for the authenticity of Mr Wright's claim.
However, others have disagreed.
Bitcoin Association of Australia board member and software engineer Lucas Cullen said Mr Wright hadn't produced adequate evidence it was the digital signature Mr Nakamoto used in the early years of bitcoin.
He said someone involved in cryptography should be able to offer more definitive proof.
"I think it is a bit of an oxymoron there to say `here's my claim, but I can't validate it' - especially when you're in that space," Mr Cullen told AAP.
American computer security researcher Dan Kaminsky also dismissed Mr Wright's proof as a hoax in a detailed blog post.
"Yes, this is a scam. Not maybe. Not possibly," Mr Kaminsky posted.
Tech sleuths have also debunked Mr Wright's claim in multiple Reddit threads outlining technical explanations of how Mr Wright made others believe he was Bitcoin's creator.
Mr Wright, however, told the BBC he didn't care if anyone believed him.
"I was the main part of it, other people helped me. Some people will believe, some people won't, and to tell you the truth, I don't really care."
Mr Wright was first connected to Mr Nakamoto in reports by technology publications Gizmodo and Wired last year.
Following the reports, Australian Federal Police raided his home on Sydney's north shore as part of an unrelated tax investigation, police said.
A former next door neighbour told AAP on Tuesday that Mr Wright, his wife and two children had moved out of the house before the raid in December and said he believed the family had since relocated to London.
The reclusive family was normal and did nothing to indicate Mr Wright was the mastermind behind Bitcoin, he said.
Mr Wright was formerly the head of alternative currency firm DeMorgan Ltd and worked as an adjunct academic at Charles Sturt University between 2011-2014.
