NFT-Based Software Execution with Metadata Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack a comprehensive solution for generating, selling, and executing software that utilizes non-fungible tokens (NFTs), particularly in ensuring secure execution and display of ownership information.
Innovation Solution
The proposed solution involves a method and device for generating and running NFT-based software, which includes receiving execution requests, loading NFT metadata, verifying execution rights, running the software, and outputting engraving data on an execution screen. This process ensures secure and transparent ownership and execution of NFT-based software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NFT metadata is loaded and execution rights are verified, then security and ownership verification are improved, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary verification mechanism that loads NFT metadata from a blockchain or centralized authority and uses it to mediate execution rights verification. This intermediary layer ensures secure ownership verification while managing system complexity through standardized verification protocols rather than complex decentralized verification logic.
2Loss of information
If engraving data is output on execution screen, then ownership transparency is improved, but display complexity increases
Solution Approach 1:
The patent extracts ownership information from the complex NFT metadata structure and presents it as simplified engraving data on the execution screen. This extraction process maintains ownership transparency by displaying relevant information (owner address, transaction hash, timestamp) while avoiding the complexity of displaying full metadata structures or blockchain data.
3Reliability
If NFT-based software is generated and packaged with digital signature, then software authenticity is improved, but generation complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-packaging software with digital signatures and NFT metadata before distribution. This preliminary packaging ensures software authenticity is established at generation time, while simplifying subsequent deployment as the authenticated package can be directly executed without additional verification steps.
Data Source
AI summary
A method and device for non-fungible token (NFT)-based software is disclosed. 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.
