a bit more information on redditApparently he verified the signature on a laptop provided by Craig, using software downloaded by Craig. And was not allowed to keep the laptop or the signed message.
hodl the phone!
if he was able to sign a new msg with known satoshi keys dating from block 1 ... i think thats irrefutable proof
but maybe the laptop used to verify was compromised.
Indeed. If Craig had a chance to tamper with the software that checks the signature, the validation is worthless.
if he would make that sig public tho there would be no doubt
Gavin says that he was not allowed to take the signed message because Craig did not want Gavn to leak the news before Craig himself did so.
Well, Craig has come public. But the signed message has not shown up. Instead, Craig's post has some signatures aken from the blockchain, and lots of words and tech stuff, so that a reader who is not quite following it may think that he has provided the signed message. But he hasn't.
Why is he doing it? Perhaps not to fool the ATO, but to fool someone else who would give Satoshi money and/or protection.
