Craig Steven Wright, the man claiming to be mysterious bitcoin founder Satoshi Nakamoto, is abruptly withdrawing from public life. Wright posted today that he would offer no more evidence to prove his identity, just days after he publicly claimed the Satoshi mantle in a series of coordinated articles. Wright’s claims were greeted with intense skepticism from many in the bitcoin community, who saw Wright as a con man using the Satoshi identity for personal gain.
As recently as yesterday, Wright had promised new evidence that would definitively prove his identity as bitcoin’s creator, writing that “extraordinary claims require extraordinary proof.” But according to the latest message published on his personal site, Wright abruptly lost the courage to carry through with the demonstration, fearing it would lead to personal attacks against him.
