Another excellent reference for all things, ProMIS is the list of essays written by J. Orlin Grabbe (deceased). They are archived at this site ...

Look for anything dealing with Vince Foster, ProMIS, Charles Hayes, or INSLAW. Grabbe was a professor at the Wharton School of Business, a well-respected authority on electronic commerce and encryption. He wrote a textbook widely used in these areas. His essays remind me greatly of the lore surrounding Q - especially the Vince Foster related stories surrounding retired CIA agent, Charles Hayes.
He also wrote essays on BCCI, PGP, Oklahoma City, Jack Parsons (Scientology, L Ron Hubbard, occult, and founder of JPL). And if still alive, he would be the go-to guy about all things "bit coin".
