Methods for user authentication using non-fungible digital assets

A method for using a non-fungible token to authenticate access to an asset, the method being implemented on a computer system having one or more physical processors configured by machine-readable instructions which, when executed, perform the method, the method comprising:

• generating a first transaction on a blockchain having an output of a fungible digital token, in which the fungible digital token comprises a first transaction hash identifier;
• generating a second transaction on the blockchain having an output of a non-fungible digital token and an input, in which the fungible digital token is spent as the input into the second transaction, the non-fungible digital token comprising a second transaction hash identifier and a group identifier associated with the first transaction hash identifier;
• requesting access from a user system to an electronic resource database, in which electronic resource database comprises the asset and access is granted to the electronic resource database based on the second transaction hash identifier and the group identifier;
• generating a third transaction on the electronic resource database to spend the non-fungible digital asset, in which the non-fungible asset is the input and the digital asset is the output, and the transaction creating a third transaction hash identifier;
• adding a signed input to the third transaction hash identifier;
• submitting the third transaction hash identifier to the blockchain for acceptance;
• and
• delivering the asset.
