satoshi’s early bitcoin code included more than just money

the first release in jan 2009 had a class called CPokerLobbyDialogBase

it contained framework for an onchain poker game

along with an irc chat client and a peer to peer marketplace

the poker code was added in april 2008

months before the whitepaper

it stayed in the codebase for years

and was only fully removed in version 0.8.2

no clear reason why it was there

but the code still exists today in the original v0.1 source on github
