A method of running the NFT-based software performed on the device includes: running the NFT-based software in response to an execution request for executing the NFT-based software; loading NFT metadata including 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. ## Claims ### Claim 1 A method of running non-fungible token (NFT)-based software performed on a device, the method comprising: receiving an execution request for executing the NFT-based software; loading NFT metadata corresponding to the NFT-based software in response to the execution request; verifying 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; running the NFT-based software based on a result of the verifying; and outputting engraving data corresponding to the NFT-based software on an execution screen displayed as the NFT-based software runs. ### Claim 2 (depends on 1) The method of claim 1, wherein the outputting of the engraving data comprises: loading the engraving data specified corresponding to the NFT-based software; and outputting an engraving content included in the engraving data based on an instruction for displaying defined in the engraving data. ### Claim 3 (depends on 2) The method of claim 2, wherein the outputting of the engraving content comprises: outputting an engraving content corresponding to an event occurring as the NFT-based software runs, based on the instruction for displaying defined in the engraving data. ### Claim 4 (depends on 1) The method of claim 1, wherein the verifying of the right comprises: verifying the right for the execution of the NFT-based software of the device, based on comparing device-related information and identification information of the device included in the NFT metadata. ### Claim 5 (depends on 1) The method of claim 1, wherein the verifying of the right comprises: verifying the right for the execution of the NFT-based software of the device, based on comparing owner-related information included in the NFT metadata and user information stored in the device. ### Claim 6 (depends on 1) The method of claim 1, wherein the NFT-based software comprises at least one content and at least one execution code. ### Claim 7 (depends on 1) The method of claim 1, wherein the NFT metadata further comprises: identification information indicating the NFT-based software; and identification information indicating an owner of the NFT-based software. ### Claim 8 (depends on 1) The method of claim 1, wherein the engraving data comprises: an engraving content indicating at least one of owner-related information or NFT-based software-related information of the NFT-based software; and an instruction for displaying the engraving content. ### Claim 9 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. ### Claim 10 (depends on 9) The method of claim 9, wherein the outputting of the engraving data comprises: loading the specified engraving data in the NFT metadata; and outputting an engraving content included in the engraving data corresponding to the event occurring as the NFT-based software runs, based on an instruction for displaying defined in the engraving data. ### Claim 11 (depends on 9) The method of claim 9, wherein the NFT metadata further comprises at least one of: an edition number assigned to the NFT-based software; identification information indicating a creator of the NFT-based software; or information associated with a device to which an execution right for executing the NFT-based software is assigned. ### Claim 12 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. ### Claim 13 (depends on 12) The method of claim 12, wherein the transmitting to the server further comprises: generating device-related information associated with a device to which an execution right for executing the NFT-based software is assigned; and transmitting the generated device-related information to the server. ### Claim 14 (depends on 1) A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform the operations of claim 1. ### Claim 15 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. ### Claim 16 (depends on 15) The device of claim 15, wherein, for the outputting of the engraving data, the processor is configured to: load the engraving data specified corresponding to the NFT-based software; and output an engraving content included in the engraving data based on an instruction for displaying defined in the engraving data. ### Claim 17 (depends on 16) The device of claim 16, wherein, for the outputting of the engraving content, the processor is configured to: output an engraving content corresponding to an event occurring as the NFT-based software runs, based on the instruction for displaying defined in the engraving data. ### Claim 18 (depends on 15) The device of claim 15, wherein, for the verifying of the right, the processor is configured to: verify the right for the execution of the NFT-based software of the device based on comparing device-related information included in the NFT metadata and identification information of the device. ### Claim 19 A device comprising: a memory storing therein non-fungible token (NFT)-based software; and at least one processor configured to: run the NFT-based software in response to an execution request for executing the NFT-based software; load 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 output the engraving data included in the NFT metadata based on an event occurring as the NFT-based software runs. ### Claim 20 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;
