# Craig Steven Wright

Craig Steven Wright (born October 1970) is an Australian computer scientist and businessman. He has publicly claimed to be the main part of the team that created bitcoin, and the identity behind the pseudonym Satoshi Nakamoto. These claims are generally regarded as false by the media and the cryptocurrency community. In March 2024, Mr Justice James Mellor in the British High Court ruled that Wright is not Satoshi Nakamoto. In July 2024, a British High Court judge referred Craig Wright to UK prosecutors for alleged perjury related to his claims of being Satoshi Nakamoto. As of 2019, Wright lived in the United Kingdom.

## Early life and education

Wright graduated from high school in 1987 from Padua College in Brisbane. Wright was an adjunct academic and researcher at Charles Sturt University, where he was working on his PhD entitled "The quantification of information systems risk". His PhD was awarded by CSU in February 2017.
Wright says he has a doctorate in theology, comparative religious and classical studies, awarded in 2003 from United Theological College.
Wright has written or co-written several books. Wright has been a trustee of the Uniting Church in New South Wales.

## Career and businesses

Wright worked in information technology for various companies, including OzEmail, Kmart and the Australian Securities Exchange, as well as working as a security consultant for Mahindra & Mahindra. He claims to have designed the architecture for possibly the world's first online casino, Lasseter's Online (based in Alice Springs, Northern Territory), which went online in 1999. He was the information systems manager for the accounting firm BDO Kendalls.
In 2004, Wright was convicted of contempt of court by the Supreme Court of New South Wales. He was sentenced to 28 days in jail for breaching an injunction that prevented him from approaching customers of DeMorgan Information Security Systems, from which he resigned in 2003. The sentence was suspended on condition of performing 250 hours of community service. After appealing the decision, the ruling was upheld in 2005 and also in a subsequent appeal to the High Court of Australia in 2006.
Wright was the CEO of the technology firm Hotwire Preemptive Intelligence Group (Hotwire PE), which planned to launch Denariuz Bank, the world's first bitcoin-based bank, though it encountered regulatory difficulties with the Australian Tax Office and failed in 2014. Wright is the founder of cryptocurrency company DeMorgan Ltd., which claimed to receive $54 million AUD in tax incentives via AusIndustry.

## Bitcoin

In December 2015, two parallel investigations by Wired and Gizmodo suggested that Wright may have been the inventor of bitcoin. Subsequent reporting, however, raised concerns that Wright was engaged in an elaborate hoax.
Hours after Wired published their allegations, Wright's home in Gordon, New South Wales, and associated business premises in Ryde, New South Wales, were raided by the Australian Federal Police. According to the AFP, the raid was part of an Australian Tax Office investigation.
On 2 May 2016, a blog post on the website www.drcraigwright.net associated Wright with Satoshi and posted a message with a cryptographic signature attached. Security researcher Dan Kaminsky said in his blog that Wright's claim was a scam, and bitcoin developer Jeff Garzik agreed that evidence publicly provided by Wright does not prove anything. Jordan Pearson and Lorenzo Franceschi-Bicchierai said that "Wright simply reused an old signature from a bitcoin transaction performed in 2009 by Satoshi."
Earlier in an interview with the BBC, Wright had promised to give "extraordinary proof to an extraordinary claim." He has yet to provide any verifiable evidence of his authorship of the original Satoshi whitepaper or collaboration with known early developers. In theory, his claim should be easy to prove, by simply supplying a message verifying the claim using the original Satoshi Nakamoto GPG private key; however, he is either unable or unwilling to provide this. On Thursday, 5 May 2016, shortly before closing his blog, Wright sent around an email link to a news story site saying: "Craig Wright faces criminal charges and serious jail time in UK". Wright stated, "I am the source of terrorist funds as bitcoin creator or I am a fraud to the world. At least a fraud is able to see his family. There is nothing I can do." The article Wright mentioned to O'Hagan has since been retracted.
In June 2016, the London Review of Books published an article by Andrew O'Hagan about the events, later included in his book The Secret Life: Three True Stories, in which O'Hagan spends several weeks with Wright at the request of Wright's public relations team; which, as revealed in the book, was set up as a result of a business deal between Wright and various individuals including Calvin Ayre. O'Hagan was with Wright during the time of his various media interviews. O'Hagan also interviews Wright's wife, colleagues and many of the other people involved in his claims.
Wright told Finder in 2019 that bitcoin's creation was a group effort, that he drove the project, and that Dave Kleiman and Hal Finney were involved.
Wright registered US copyright in the bitcoin white paper and the code for bitcoin 0.1 in April 2019. A spokesman for Wright told the Financial Times that this was "the first government agency recognition of Craig Wright as Satoshi Nakamoto, the creator of Bitcoin"; the United States Copyright Office issued a press release clarifying that this was not the case, and that "the Copyright Office does not investigate whether there is a provable connection between the claimant and the pseudonymous author."
In order to resolve Wright's claim of being Satoshi Nakamoto, the Crypto Open Patent Alliance (COPA) sued Wright in the High Court in London, and hearings were heard in February and March of 2024. On 14 March, after a five-week trial Mr Justice Mellor ruled that Wright is not Satoshi Nakamoto. The written judgment released on 20 May stated that documents submitted as evidence to substantiate Wright's claim to be Satoshi were forgeries, and Dr Wright had "lied to the court extensively and repeatedly".

### Legal issues
#### Dave Kleiman estate

In February 2018, the estate of Dave Kleiman initiated a lawsuit in the U.S. District Court for the Southern District of Florida against Wright over the rights to US$5 billion of bitcoin, claiming that Wright defrauded Kleiman of Bitcoins and intellectual property rights.
In August 2019, Magistrate Judge Bruce Reinhart, ruling on a motion to force Wright to list his early bitcoin holdings, ordered that, for the purposes of this case, the Kleiman estate owned half the bitcoin holdings that Wright mined in partnership with Kleiman from 2009 to 2013, as Wright's "non-compliance with the court's orders is willful and in bad faith." Wright was also ordered to transfer half of the partnership's intellectual property as well as pay Kleiman's reasonable attorney fees in bringing the motion. Reinhart said that the court was not required to decide, and would not decide, whether Wright was Satoshi Nakamoto, and was not required to decide and did not decide how much bitcoin Wright controlled.
Reinhart said that "Dr. Wright's demeanor did not impress me as someone who was telling the truth" and that he rejected Wright's testimony in the motion: "Dr. Wright’s story not only was not supported by other evidence in the record, it defies common sense and real-life experience."
Following a three-week trial in late 2021, a jury found Wright liable for conversion but awarded Kleiman's estate US$100 million in damages while Kleiman's estate had sought upwards of US$25 billion at trial. Wright took the position that verdict served as a vindication of his role in inventing bitcoin and stated that he would not appeal the jury's findings.

#### Defamation cases

In May 2019, Wright started using English libel law to sue people who accused him of lying about being the inventor of bitcoin, and who called him a fraud. Wright also served legal notices to Vitalik Buterin, the founder of the cryptocurrency Ethereum, who called Wright a fraud; Roger Ver, an early bitcoin entrepreneur and advocate; and Peter McCormack, a podcaster. Wright ended up dropping his lawsuit against Buterin by letting it expire.
In the case against McCormack, the High Court judge was not asked to decide whether Wright is Satoshi, as by the time of the trial McCormack was not defending his statements on the basis that they were true, but as the judge found Wright "not to be a witness of truth" who had "advanced a deliberately false case and put forward deliberately false evidence until days before trial" he awarded him only £1 in damages.
In June 2019, Wright filed a libel lawsuit in the UK against a Norwegian bitcoin user, Marcus Granath, known on social media as "Hodlonaut". Granath, who has stated that Wright is not Nakamoto, then filed a lawsuit against Wright in Norway in order to provide legal corroboration for his assertions; in October 2022, the Norwegian court decided in Granath's favor.
In response to Wright's actions preceding the Hodlonaut lawsuit, Changpeng Zhao, founder of crypto exchange Binance, called Wright out as a fraud.
