Public key cryptography is absolutely not exclusive to Bitcoin, and appending your title with "Bitcoin" is quite the blunder. PKC is the basis of (almost) all encryption of server-client communication, such as web traffic. That HTTPS in front of https://lemmy.world? That's PKC. Bitcoin too, sure, but also every other cryptocurrency/token out there as well - including NFTs. It is quite interesting that we can partially thank Dr. Tits for an element of what has become a foundational component of so much modern tech, but in the context of this community I'd say its more relevant to attribute Jacque to the former Gamestop NFT Marketplace & Playr.... OR whatever comes after.
This book was published after the planned cancellation of the NFT marketplace. One of the primary questions in my mind is why has GME seemingly abandoned all NFT & crypto-related endeavors? NFTs are the perfect solution for the ability to resell digital games, which is Gamestop's legacy bread & butter. With Microsoft's recent reveal of a disc-less Xbox future (and Sony rumored as well), something has to be brewing - with or without Microsoft or Sony.
