The pseudo-anonymous creator of bitcoin, known as Satoshi Nakamoto, created bitcoin in 2008 and went anonymous immediately after its launch in 2019, erasing any possible digital signature without a trace. There have been numerous speculations as to the identity of the original creator and many have claimed to know the real individual behind it, but none have offered any conclusive evidence.
However the similarities between Szabo's writing and the whitepaper of bitcoin actually seem "disturbing": a 2014 report by a linguistics team has in fact highlighted the strong similarities, stating that the number of linguistic similarities between the two is something that makes it the closest hypothesis to being the original Satoshi. "The number of linguistic similarities between Szabo's writing and the bitcoin white paper is disturbing," said the researchers, adding that "none of the other possible authors had such good matches."
