I heard that the name may be a pseudonym and that very little is known about the initiator of bitcoin. Also it seems that he has stopped working on the main client.

When was his last verifiable life sign? Did he ever mention or announce his retirement?

    I'd say this is substantially different from the "who is" question.

    It's off topic. This site is about Bitcoin. It doens't need to become fodder for Who-is-Satoshi-Nakamoto trivia. Any biographical information you feel the need to expound on can easily be contained in the other thread. No need to perpetuate this this content of dubious value through the site.

    @Robert You claimed (probably rightly so IMO) that it was off-topic, yet you closed it as "exact duplicate." It's a pet peeve of mine that far, far too many questions on SE are closed as exact duplicate when they are NOT exact duplicates. Commented Aug 31, 2011 at 21:59

    @Robert- I say this is on topic.

    Why this question was closed? I really didn't understand the reason. I had the same doubt of the author of the question. It is very important to Bitcoin history and community. Seriously, this question is basic and if it is "off topic" I don't know what can be said or questioned about Bitcoin here. The Bitcoin wiki should be enough. This is definitely not off-topic and must be re-opened.

This was his last post on the Bitcoin Forums, December 12th, 2010. The day after he wrote this to the mailing list. As far as I know he did not (publicly) announce his retirement.


The creator of Bitcoin Satoshi Nakamoto sent his final emails to fellow developers in which he was transparent that he had moved on to other projects, during the time of handing over a cryptographic key he had utilized to send network-wide alerts.
