Analysis proves: The time zone when Satoshi Nakamoto emailed Hal Finney was not UTC+8
This article is compiled from he Chain Bulletin, by Doncho Karaivanov
On November 27 this year, Coindesk reported a news that the content is Chinese The early days of Satoshi Nakamoto and the late Hal Finney, an early Bitcoin developer, via email friendly communication, these emails are marked with UTC+8 time.
The emails are understood to have been sent by journalist and author Nathaniel Popper ) publicly, and he quoted this part of the email when he wrote the book "Digital Gold: Bitcoin and the Inside Story of the Misfits and Millionaires Trying to Reinvent Money".
Before publication, CoinDesk reached out to Hal’s widow, Fran Finney, for confirmation , the latter confirmed that it had provided Hal's emails to Popper, "In March 2014, we sent Nathaniel Popper those documents recording the emails between Hal and Satoshi Nakamoto. contacts," Fran Finney said.
This shows that the published email content is true . In fact, these emails not only reveal how closely Satoshi Nakamoto worked with early supporters when Bitcoin was launched; valuable. Perhaps the most interesting part of this information, which is neither text nor code, is something seemingly mundane: the timestamp, which brings up a new puzzle.
The author of the article reminds readers: the time zone marked in the email is displayed as UTC+8, does this mean that Nakamoto Satoshi was somewhere in Asia at the time?

At first glance, this may seem to support the argument, but upon closer inspection of the emails, it turns out that it is Incorrect.
Generally, the date displayed in the email is set by the email client used by the user, e.g. Thunderbird, Mailbird, Postbox and other service providers that provide Webmail services, if users use these clients, the time zone in the date header field is the local time zone of the computer.
(Note: Webmail is a major A service that uses a web browser to read or send e-mail, as opposed to an e-mail service that uses e-mail client software such as Microsoft Outlook, Mozilla Thunderbird, etc. Companies such as Google, Yahoo, and Sina, as well as other Internet service providers may also offer This service is convenient for users to directly use their mail services without going through the Internet terminal they usually use.)
However, if you are using a Webmail client, the time zone marked on the email is actually the server where the email is hosted. In the above email, Satoshi Nakamoto used the webmail client of AnonymousSpeech.com, so it can be ruled out that the time marked in the email is the time in the time zone where Satoshi Nakamoto is located.
Specifically, Satoshi Nakamoto’s email letterhead indicated that it used the name “anonymousspeech h.com ” mail server: the fifth line in the above figure shows “receipt: from mail.anonymousspeech h.com (anonymousspeech h.com [124.217.253.42])”.
As far as I know, AnonymousSpeech.com is a platform specially designed for sending anonymous emails - their slogan was the "leader in anonymous email" and still supports guest services to this day.
In addition, the X-Mailer of the mail indicates the mail client Satoshi Nakamoto used to send mail—— From Chilkat Software. It is understood that Chilkat is a cross-language, cross-platform API that provides services for many Internet protocols, including email.
So it is probably reasonable to assume that the anonymousspeech h.com webmail client uses Chilkat's API.
In addition to the above evidence, a recent study published by Chain Bulletin shows that Satoshi Nakamoto did not live in Asia when he was researching Bitcoin, which can also prove the accuracy of the guess .
So why does anonymousspeech.com show UTC+8? Analysts found that the November 2006 Web Archives can see: anonymousspeech h.com LLC specializes in international law and IT security consulting, established since 1996 in Tokyo, Japan. Operating primarily in Japan, the team advises clients on international legal issues and Internet security.
Therefore, when Satoshi Nakamoto sent an email to Hal Finney, as the sender Satoshi Nakamoto used the service of AnonymousSpeech.com, the time zone displayed in the email was actually the mail server deployed in Japan at that time. It does not say where Satoshi Nakamoto is located. On the contrary, because of this method, Satoshi Nakamoto "hidden" his real location.
