Negative Proved: Craig Wright<>Satoshi Nakamoto
Not that any of us believed his claims in the first place; not least as a result of his continuing failure to present the promised digital proof.
It is, however, usually difficult to prove a negative. But this, I would argue, nails it:
"But an expert took a look at the email and concluded from the email’s digital signature that it has been sent in early 2014."
Whatever other criticisms you may aim at Bitcoin, its real author clearly and fully understood the issues around immutablity and the digital proof of data integrity. No one with that level of comprehension could possibly have imagined that they'd get away with forging an email in 2014, which relied on a timestamped digital signature.
Ergo, this charlatan can not be that still anonymous author.
