  "name": "Cross-Chain Publication NFTs for Academic Publishing",
  "description": "We present the PublicationNFT project, which is a framework to mint and manage non-fungible tokens (NFTs) for academic publishing. Existing NFT projects for academic publishing store metadata off-chain, which prevents smart contracts from reading this data and limits interoperability. As research becomes more digital, we need solutions that ensure proof of authorship while being compatible with automated systems that can interact with on-chain data. PublicationNFT provides such a solution with rich on-chain metadata that is immutable, machine-readable access through on-chain function calls and Schema.org standards, and optimized minting processes to reduce costs and improve efficiency.",
