Earlier in an interview with the BBC, Wright had promised to give "extraordinary proof to an extraordinary claim." He has yet to provide any verifiable evidence of his authorship of the original Satoshi whitepaper or collaboration with known early developers. In theory his claim should be easy to prove, by simply supplying a message verifying the claim using the original Satoshi Nakamoto GPG private key; however, he is either unable or unwilling to provide this. On Thursday, 5 May 2016, shortly before closing his blog, Wright sent around an email link to a news story site saying "Craig Wright faces criminal charges and serious jail time in UK". Wright stated that "I am the source of terrorist funds as bitcoin creator or I am a fraud to the world. At least a fraud is able to see his family. There is nothing I can do." The article Wright mentioned to O'Hagan has since been retracted.
