November 22, 2009 | Who Created Bitcoin Forum?

On November 22, 2009, an individual or a group operating under the pseudonym Satoshi Nakamoto initiated the use of SourceForge's platform to create a communication link between Bitcoin developers and users using mailing lists.

These mailing lists functioned more like email-based discussion threads than a traditional online forum.
Still, Satoshi could've used Sourceforge's forum feature to create a temporary forum for a short period, which was later deleted (However, this occurred before current admin's tenure, so it may be inaccurate).

After utilizing SourceForge's mailing lists, Satoshi and Sirius created the forum at www.bitcoin.org/smf,
Which later moved to www.forum.bitcoin.org around May 2011.

After mailing lists, Satoshi and Sirius (Martti Malmi) created the standalone forum Bitcointalk.org in June 2011.
While additional contributors may have been involved in its development, these are the only ones publicly known.
It’s worth noting that Satoshi actively served as an administrator during this period, managing spam and implementing minor software tweaks (some of which are still in the code today). Then, in late 2010, Satoshi left.

The forum required staff support, so various individuals were appointed.
The forum's present admin stated that he was initially assigned the moderator role out of necessity.
Subsequently, he was appointed an admin and managed the forum with Sirius. In January 2012, a new head admin was appointed after Sirius left the forum.

Later, admin and Cøbra managed the domains Bitcointalk.org and Bitcoin.org (both created by Satoshi). Cøbra maintained limited involvement in the forum's operations and eventually departed from the project. Cøbra now serves as the administrator of Bitcoin.org.

The forum's admin mentioned: A few people were worried that the forum was too chaotic to be on Bitcoin.org, so they convinced Sirius to split it off from Bitcoin.org. Jeff Garzik was one of the prominent people trying to convince Sirius to make this split, and he registered the Bitcointalk.org domain. This renaming happened in August 2011.

Currently, the Bitcointalk forum is overseen by 2 Administrators, 3 Global moderators, and 19 Staff members. - (April, 2025 Data).
