The White Paper LaTeX Files purport to use a package called “luacode” {L21/9.1/4}. That package defines a few convenience functions to make it easier to use the Lua language from within LuaTeX {Rosendahl1 [150]{G/7/48}}. However, the package was not issued until November 2010 {Rosendahl1 [150] {G/7/48}}, and so cannot have been used in the creation of the Bitcoin White Paper.
