Judge James Mellor, who ruled after a civil trial in March that Craig Wright was not the man behind "Satoshi Nakamoto", the pseudonym that has masked the creator of bitcoin's identity, said he would refer evidence from the case to the Crown Prosecution Service (CPS) to consider whether to bring charges.
"In advancing his false claim to be Satoshi through multiple legal actions, Dr Wright committed 'a most serious abuse' of the process of the courts of the UK, Norway and the USA," Mellor said on Tuesday.
"If what happened in this case does not warrant referral to the CPS, it is difficult to envisage a case which would."
The High Court judge had ruled at trial that Wright did not invent bitcoin, was not the man behind Nakamoto, or creator of the bitcoin software, saying in a written judgment that Wright lied "extensively and repeatedly" and forged documents "on a grand scale" during the case.
The murky origins of bitcoin date to the height of the financial crisis in 2008, when a person or group using the Nakamoto pen name issued a paper explaining how digital currency could be sent around the world anonymously, without banks or national currencies.
Speculation on the identity of Nakamoto swirled for years and several candidates had emerged when Wright emerged to claim the identity in 2016, only to quickly return to the shadows, saying he did not "have the courage" to provide more proof.

In what was considered a major victory for open source developers, a non-profit group of technology and crypto companies successfully sued in the High Court to prove Wright is not Nakamoto.
The Crypto Open Patent Alliance had argued Wright had committed "forgery on an industrial scale" to support a "brazen lie" he was Nakamoto.
The alliance said he used his claim as bitcoin's inventor to "terrorise" developers by filing litigation to prevent them further developing the open-source technology.
Wright, who testified over several days of the five-week trial, denied the allegations.
In May, he said on the social media platform X that he planned to appeal the decision "on the matter of the identity issue".
The trial had implications for control of the intellectual property rights of the world's most popular virtual currency.
The ruling affected three pending lawsuits Wright filed based on his claim to having the intellectual property rights to bitcoin.
Mellor granted two injunctions on Tuesday preventing Wright from threatening to sue or filing lawsuits aimed at developers.
He also ordered Wright to publish details of the ruling against him to "dispel residual uncertainty" that he was not Nakamoto and post notices to that effect on his website and his profile on X, the social media platform, and his Slack channels.
Messages seeking comment from Wright's lawyers were not immediately returned.
Bitcoin is the world's most high-profile digital currency, and like others is not tied to any bank or government.
Like cash, it allows users to spend and receive money anonymously, or mostly so.
It can be converted to cash when deposited into accounts at prices set in online trading.
