Jon Matonis in a blog post,[57] stated "For cryptographic proof in my presence, Craig signed and verified a message using the private key from block #1 newly-generated coins and from block #9 newly-generated coins (the first transaction to Hal Finney)." Gavin Andresen said that he performed a careful cryptographic verification of messages signed, [by Craig], with keys that only Satoshi should possess.[58]

"I believed that I could do this. I believed that I could put the years of anonymity and hiding behind me. But, as the events of this week unfolded and I prepared to publish the proof of access to the earliest keys, I broke. I do not have the courage. I cannot. When the rumours began, my qualifications and character were attacked. When those allegations were proven false, new allegations have already begun. I know now that I am not strong enough for this. I know that this weakness will cause great damage to those that have supported me, and particularly to Jon Matonis and Gavin Andresen. I can only hope that their honour and credibility is not irreparably tainted by my actions. They were not deceived, but I know that the world will never believe that now. I can only say I’m sorry. And goodbye.[63]"
