Re: Alts market if C. Wright moves coins from early blocks
Can someone explain how he signed the 'Satre' quote WITHOUT having to break SHA256 (finding a collision) ?
It's pretty important, as if he did do that, Bitcoin is broken.

He never used the hash of any Sartre quote (that was just misdirection) - the double hash that he used was simply that used in Satoshi's tx along with the signature that was used in the tx.
(basically he just copied and pasted from the blockchain then put together an elaborate pretense that he had somehow managed to sign something else using a private key known to belong to Satoshi)
Even the silly BBC report has been corrected once they finally worked out that they had been tricked.
Oh.. I see.. thanks.
How can 'big boys' like Gavin and Matonis have fallen for this.. !? That shows very poor skills..
( ..too poor if you ask me.. ) No one has presented a script which hashes all portions of the Sartre text to verify whether it does or does not hash to the correct value.
Until someone does that, they can't be sure that Craig won't reveal the Sartre text which does hash to the correct value, thus proving that he broke the cryptography. Since the SHA-256 was already broken to 46 - 52 rounds of the 64 rounds (for a single hash), then doubling the hash as Bitcoin does could potentially break it for all 64 rounds, because ostensibly collision resistance gets worse when doubling a hash (as I had explained in detail upthread). No one knows why Satoshi designed Bitcoin with a double hash. I am positing it might be a back door.
CIYAM is misleading you. Follow an idiot if you want to be one.
