A leading figure in the Bitcoin community has expressed regret about a blog backing an Australian’s claim to have invented the crypto-currency.
Craig Wright announced on Monday that he was behind Satoshi Nakamoto – the pseudonym used by Bitcoin’s creator.
The same day, Gavin Andresen, chief scientist at the Bitcoin Foundation, wrote he was “convinced beyond a reasonable doubt” of Dr Wright’s case.
But Mr Andresen said he now thinks it was a “mistake” to have posted.
The expert had written that he had privately witnessed Dr Wright using cryptographic keys that “only Satoshi should possess”.
But critics called Dr Wright’s claim into doubt when it emerged that part of the evidence the entrepreneur presented in public could have been generated using a string of digits linked to a seven-year-old transaction made by Satoshi, accessible via a search engine.
“It was a mistake to agree to publish my post before I saw his – I assumed his post would simply be a signed message anybody could easily verify,” Mr Andresen told security researcher Dan Kaminsky when he challenged the scientist over the matter.
