New York Times - "My Quest to Solve Bitcoin’s Great Mystery"
"So I decided to ask Mr. Back for the emails’ metadata. Metadata is to an email what an envelope, postmark and seal are to a physical letter: It shows where the email came from, when it was sent and whether it was altered. The copies of Mr. Back’s email exchanges with Satoshi made public during Mr. Wright’s London trial hadn’t included this information.
I didn’t have high hopes the metadata would tell me anything useful because Satoshi had used the Tokyo-registered anonymous email service, which would have masked his I.P. address. Not only that, Satoshi had probably used Tor to connect to the service to further insulate himself. I still wanted to see it, though, on the off chance I could glean some clue.
But when I emailed Mr. Back my request, he did not reply. I wasn’t sure if he was ghosting me or just busy and I didn’t want to spook him by immediately following up, so I waited eight days to send him another email. Again, radio silence.
I had clearly touched a nerve. But why? With the precautions Satoshi had taken, what was there to even hide? Unless Satoshi had made some sort of mistake?"
