The original client that can be downloaded from www.bitcoin.org is often referred to as the "official client". Similarly many regard www.bitcoin.org as the "official homepage" of the project. So, who runs it? Is it the core developers? Some Bitcoin association? Or just a private person?

Collecting some of the publicly available information that I found.

Martti Malmi (aka Sirius), a student of Aalto University in Finland, was one of the core developers early on in the project. Satoshi attributed some of the new features of version 0.2 to him here and he was the one making the first commits to the Sourceforge repository back in August 2009. He was removed from the list of project developers on bitcoin.org in June 2011.

As Andrew points out in his answer, both bitcoin.org and bitcointalk.org is owned by Martti. He is the administrator of the bitcointalk.org forums, still active there, and could most likely be contacted using the PM feature on the forums. Both Martti and Gavin Andresen (lead developer) have access to the bitcoin.org website.

Edit September 25th, 2011: The code for the bitcoin.org website is now hosted under the Bitcoin project on GitHub. This means that you can post issues/suggestions there or make a pull request if you wanna add or change something.

  • It's my understanding that bitcointalk.org has been switched to a new arrangement after the recent hack. Commented Sep 14, 2011 at 1:53

    Well, Mark (of MtGox) took over the hosting I believe. Martti still owns the domain. I will update my answer once I've looked it up more carefully.

    Sirius continues to have exclusive control over the DNS for both sites, though hosting is now handled by other people.

As pointed out by theymos on Bitcoin Talk, both bitcoin.org and bitcointalk.org are owned by Sirius.

    +1. It would be interesting to know more though. What is the role of Sirius in the Bitcoin project and is there anyway for the community to have a say about what should be on this "official" homepage?

According to DNS Lookup wwww.bitcoin.org is (today) just another another name for vhost.sourceforge.net so it is run by the sourceforge guys. As the DNS Authority for the www subdomain is bitcoin.org you might be interested in that as well.

According to WHOIS bitcoin.org is run by:

Domain ID:D153621148-LROR
Created On:18-Aug-2008 13:19:55 UTC

Although it does not look very trustworthy this is a common hosting setup. It may differ from NIC to NIC but usually the real "owner" or his responsible person is mentioned as Admin.

    ... it is hosted by github as of today Commented Sep 5, 2011 at 0:36
  • For bitcoin.org is still registred to Louhi Net Oy, www.bitcoin.org seem to have been moved and is now an alias for bitcoin.org. GitHub is where the source code is officially stored, sourceforge where the binaries are.
