London's High Court has paved the way for a case that could force its judges to take a view on who invented bitcoin, the world's biggest cryptocurrency which last week soared to all-time highs.
The court has allowed Craig Wright, an Australian computer scientist who alleges he created bitcoin, to serve a copyright infringement lawsuit against the operator and publisher of the bitcoin.org website, which calls itself Cobra, over Twitter or a generic email address.
Wright can now try and pursue his case -- titled Wright v Person(s) unknown, "Cobra" -- although the defendant might be resident abroad and has not disclosed a name, identity or address, according to court filings issued on Wednesday and seen by Reuters on Thursday.
The case hinges on who wrote bitcoin's white paper, which first outlined the technology behind the digital currency, under the pseudonym Satoshi Nakamoto in 2008.
The identity of Nakamoto has long been a hot topic and Wright's claim is fiercely disputed, not least by Cobra.
"Bitcoin.org isn't based in the UK and Craig's copyright claims over the whitepaper can be easily verified to be false ... ," Cobra messaged Wright's lawyers Ontier over Twitter on January 20, according to court filings.
Wright, who is resident in Britain and alleges he has the evidence to support his claims, accuses Cobra of wrongfully controlling the bitcoin.org website and demanded that it remove the white paper.
"The case will turn on whether the court is satisfied that Dr Wright did indeed author – and owns the copyright in – the White Paper and, therefore, that he is Satoshi Nakamoto," said Simon Cohen, a lawyer at Ontier, representing Wright.
A statement published on bitcoin.org on January 21 dismissed the claims as "without merit".
Reached by email, Cobra said: "We've been threatened to take down the Bitcoin white paper by someone who obviously isn't the inventor of Bitcoin (if he was, that would make him the 25th richest person in the world, which he obviously isn't).
"Seems like he's trying to abuse the UK courts to make them try to censor the white paper and harass small websites like us providing education content with his behaviour."
It remains unclear whether Cobra will reveal its identity to defend the claim and avoid risking any default judgment in Wright's favour.
Bitcoin has gained nearly 90 percent this year and hit a record of almost US$65,000 (A$84,000) last week.
