The introduction of a novel token standard, specifically a variable non-fungible token, which allows for efficient interaction with legacy systems, minimizes security issues, and maintains high transaction speeds by storing metadata off-chain and using a non-transferable smart contract address for updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain technology is implemented with conventional token standards, then immutability and security are improved, but adaptability to legacy systems and ease of operation deteriorate
Solution Approach 1:
The patent segments the token into two distinct parts: an on-chain component stored in the smart contract that ensures immutability and security, and an off-chain component (metadata) stored externally that enables flexibility and compatibility with legacy systems. This segmentation allows each part to fulfill its specific function without compromising the other.
Solution Approach 2:
The patent introduces an intermediary mechanism (the hybrid token structure with off-chain metadata and on-chain verification) that bridges blockchain technology and legacy systems. This intermediary enables legacy systems to interact with blockchain tokens without requiring deep understanding of blockchain protocols, thus improving ease of operation while maintaining security.
2Reliability
If blockchain technology is implemented with conventional standards, then security is improved, but ease of operation and integration with legacy systems deteriorate
Solution Approach 1:
The off-chain metadata acts as an intermediary layer that simplifies integration with legacy systems. Legacy systems can store and retrieve metadata using conventional methods while the on-chain smart contract handles security-critical operations, making the overall system easier to operate without compromising security.
Solution Approach 2:
The patent extracts the complex blockchain-specific elements (immutable storage requirements, consensus mechanisms) from the token functionality and places them only where necessary (on-chain). The remaining functionality (metadata storage, flexible updates) is moved off-chain, reducing the operational complexity for users and integrators.
3Reliability
If metadata is stored on-chain to ensure immutability, then reliability is improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent segments data storage between on-chain and off-chain locations based on requirements. Only critical immutable data (token ownership, basic properties) is stored on-chain, while mutable metadata is stored off-chain. This reduces the complexity and size of on-chain storage requirements significantly.
Solution Approach 2:
The patent extracts mutable metadata from the on-chain smart contract and stores it off-chain. This extraction reduces the complexity of the smart contract and the energy consumption associated with storing and verifying large amounts of metadata on the blockchain, while maintaining immutability for critical token attributes.
4Reliability
If conventional non-fungible tokens are used, then security is improved, but adaptability to variable metadata requirements deteriorates
Solution Approach 1:
The patent introduces dynamic metadata that can be updated off-chain while maintaining on-chain verification. This allows the token to adapt to changing requirements (such as updating NFT metadata, modifying token properties) without requiring on-chain transactions, thus improving versatility while maintaining security through selective on-chain verification.
Solution Approach 2:
The patent segments the token data structure into static on-chain components (ensuring security and immutability) and dynamic off-chain components (enabling flexibility and adaptability). This segmentation allows the token to maintain security guarantees while adapting to variable metadata requirements through off-chain updates.
Data Source
AI summary
Systems and methods related to a variable non-fungible token that dynamically update metadata during blockchain functions. A variable non-fungible token comprises a non-fungible token that is minted with an indication of a non-transferable ownership wallet (e.g., a digital wallet for which the non-fungible token is minted for), a non-transferable smart contract address that has permissions for updating metadata for the variable non-fungible token, and a metadata property threshold based on a specific user corresponding to the digital wallet.
