Abstract
A system for identity authentication on blockchain using NFTs includes a user interface, an identity NFT minting module, and a verifiable credential issuer module. The user interface allows a user to link a blockchain wallet and a credential wallet to the user interface and to provide an online service ID and requests the user to create signatures using a blockchain wallet private key and a credential wallet signing key. The identity NFT minting module verifies the online service ID and verifies the two signatures using the blockchain wallet address and the DID. The identity NFT minting module mints an identity NFT on a blockchain network, preserving the online service ID, the blockchain wallet address, and the DID in the identity NFT as metadata. The verifiable credential issuer module issues a verifiable credential to the user and triggers the identity NFT minting module for adding credential metadata to the identity NFT.
