On this day 17 years ago, on January 17, 2009, Satoshi Nakamoto released the first version of the Bitcoin client v0.1, namely: Bitcoin v0.1 Alpha, which allowed anyone to start their own node from any computer.

It is reported that the source code of Bitcoin 0.1.0 also included an Internet Relay Chat (IRC) client, aimed at creating a simpler way to guide message transmission. Additionally, it contained a framework for creating virtual poker games, which was added to the Bitcoin version on April 16, 2008, and was completely removed after the Bitcoin 0.8.2 version.
