The idea is a network of decentralized "virtual schools" (book publishers, teachers/educators, instructional designers, institutions, motion graphic artists, anyone) authoring and publishing Dopalearn compliant training (aka "Pop-up Training") and monetizing it. Each school licensed and provided with "keys" (housed in the NFTs) that allows their customers to use/open them (the training) in Dopalearn. So technically, the NFT will be housing the course metadata (source of the JSONs/mp3s) and the license/key that makes it Dopalearn compliant.
Does that mean all party (customer, school, etc.)
depends on Dopalearn server (which is centralized) to access the content? If yes, i would call your idea is centralized or semi-centralized "virtual school".
