1. An NFT-based document publication notification message generating apparatus, comprising:
at least one memory;
a component collection stored in the at least one memory;
at least one processor disposed in communication with the at least one memory, the at least one processor executing processor-executable instructions from the component collection, the component collection storage structured with processor-executable instructions, comprising:
obtain, via the at least one processor, a document publishing request datastructure structured to specify a set of document info fields associated with a document, in which the set of document info fields includes a document identifier and document contents;
generate, via the at least one processor, a hash of the set of document info fields associated with the document;
store, via the at least one processor, a document object associated with the document in an adjunct repository, in which the document object is structured to specify the set of document info fields and the hash;
submit, via the at least one processor, a document publishing transaction to a blockchain, in which the document publishing transaction is structured to facilitate storing publication information regarding the document via the blockchain, in which the publication information includes the hash;
generate, via the at least one processor, an NFT metadata datastructure structured to specify the document identifier and an identifier of the document publishing transaction;
determine, via the at least one processor, a set of subscribers for the document;
mint, via the at least one processor, for each respective subscriber in the set of subscribers, a notification NFT by sending a blockchain transaction to a document publication notification generating smart contract deployed on the blockchain, in which the document publication notification generating smart contract is structured to associate the generated NFT metadata datastructure and a subscriber blockchain address associated with the respective subscriber with the notification NFT; and
send, via the at least one processor, for each respective subscriber in the set of subscribers, a subscriber notification message for the respective subscriber via a communication method specified for the respective subscriber, in which the subscriber notification message is structured to specify an identifier associated with a notification NFT minted for the respective subscriber.
