Australian entrepreneur Craig Wright has put an end to the years-long speculation about the creator of Bitcoin. In an interview with the BBC, The Economist (may have a paywall), and GQ, Wright claimed that he is indeed the person who developed the concepts on which Bitcoin cryptocurrency is built. According to the BBC, Mr. Wright provided "technical proof to back up his claim using coins known to be owned by Bitcoin's creator." Wright writes in a blog post: [A]fter many years, and having experienced the ebb and flow of life those years have brought, I think I am finally at peace with what he meant. If I sign Craig Wright, it is not the same as if I sign Craig Wright, Satoshi[...] Since those early days, after distancing myself from the public persona that was Satoshi, I have poured every measure of myself into research. I have been silent, but I have not been absent. I have been engaged with an exceptional group and look forward to sharing our remarkable work when they are ready. Satoshi is dead. But this is only the beginning. According to Wright's website, he is a "computer scientist, businessman and inventor" born in Brisbane, Australia, in October 1970. Some have questioned the authenticity and relevance of the "technical proof" Wright has provided. Nik Cubrilovic, an Australian former hacker and leading internet security blogger, wrote, "I don't believe for a second Wright is Satoshi. I know two people who worked with Wright, characterized him as crazy and schemer/charlatan." Michele Spagnuolo, Information Security Engineer at Google added, "He's not Satoshi. He just reused a signed message (of a Sartre text) by Satoshi with block 9 key as 'proof.'"
