If I tell you right now that every single digital dollar will need to include the finger print of the digital printing press that created it. How would you be able to forge a new one without that fingerprint? You can't because every time you alter the digital dollar you create a new fingerprint that does not match the original digital printing machine.

This fixes a lot of problems with altering code and and extensions and modding. Does not fix memory changes but it can make it quite difficult because each memory change would have to be validated against the original fingerprint already registered on the server for your particular build.
