Method and device for nft-based software

A method of running non-fungible token (NFT)-based software performed on a device, the method comprising:

• running the NFT-based software in response to an execution request for executing the NFT-based software;
• loading NFT metadata comprising identification information indicating the NFT-based software, identification information indicating an owner of the NFT-based software, and specified engraving data, in response to the execution request;
• and
• outputting the engraving data included in the NFT metadata based on an event occurring as the NFT-based software runs.

A method of generating non-fungible token (NFT)-based software performed on a device linked with a server for trading the NFT-based software, the method comprising:

• defining engraving data output based on the NFT-based software running;
• transmitting, to the server, the defined engraving data and a file to be generated as the NFT-based software;
• receiving, from the server, encoded data corresponding to the file generated based on the engraving data and the NFT metadata corresponding to the NFT-based software;
• generating packaged NFT-based software by adding, to the encoded data, a digital signature for verifying the NFT-based software;
• and
• transmitting the packaged NFT-based software to the server.

A device comprising:

• a memory storing therein non-fungible token (NFT)-based software;
• and
• at least one processor configured to:
• receive an execution request for executing the NFT-based software;
• load NFT metadata corresponding to the NFT-based software in response to the execution request;
• verify a right for execution of the NFT-based software based on at least one of device-related information or owner-related information included in the NFT metadata;
• run the NFT-based software based on a result of the verifying;
• and
• output engraving data corresponding to the NFT-based software on an execution screen displayed as the NFT-based software runs.

A device comprising:

• and
• output the engraving data included in the NFT metadata based on an event occurring as the NFT-based software runs.

A device comprising:

• a communication module comprising communication circuitry configured to communicate with a server for trading non-fungible token (NFT)-based software;
• and
• at least one processor configured to:
• define engraving data to be output based on the NFT-based software running;
• transmit, to the server, the defined engraving data and a file to be generated as the NFT-based software;
• receive, from the server, encoded data corresponding to the file generated based on the engraving data and the NFT metadata corresponding to the NFT-based software;
• generate packaged NFT-based software by adding, to the encoded data, a digital signature for verifying the NFT-based software;
