Proof of concept demonstration on how to implement a blockchain to track game currency and purchase of game items.  In this demonstration, the blockchain is created in PHP on a Fedora Linux virtual machine running in Virtual Box.  The block chain is pulled into Unity through C# networking code.  Regular expressions are used to parse the blockchain to return the user’s game currency and items purchased.
