Craig Wright, the Australian computer scientist who claimed to be Satoshi Nakamoto, the creator of bitcoin, has backtracked on a pledge to provide proof of his earlier claims.
Despite promising on Tuesday that he would be offering “extraordinary evidence” to verify his claim that he is really Satoshi Nakamoto, Wright wiped his blog on Thursday, replacing it only with a message headlined: “I’m Sorry.”
In the new message, Wright continues to maintain that he really is Nakamoto, but accepts that the total absence of credible evidence means few are likely to believe him. “I believed that I could do this,” he writes. “I believed that I could put the years of anonymity and hiding behind me.
