A credential NFT (non-fungible token) replaced ODEM’s previous model of the digital Ethereum-based credential.
The NFT credential differs in that it becomes automatically and explicitly owned by the user once the issuer creates it. The user needs to acknowledge and accept the NFT, which is then stored in three places:
1. The IPFS blockchain
2. The user’s ODEM profile, which includes a link that can be shared on other platforms
3. As a downloadable version
