AR NFT Metadata Architecture for Dynamic Ownership Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
NFTs are susceptible to 'link rot' and lack mechanisms for dynamic, user-driven changes to metadata, limiting their interactive and ownership transfer capabilities, especially in augmented reality applications.
Innovation Solution
The system generates 'one-of-a-kind' NFTs with mutable metadata, allowing users to edit graphical and textual attributes, and supports 'open-edition' NFTs with smart contracts, enabling dynamic changes recorded on a blockchain and decentralized database.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NFTs store only immutable data on blockchain, then ownership tracking is secure and reliable, but the NFT cannot support dynamic metadata changes or user-driven modifications
Solution Approach 1:
The patent segments NFT data into two parts: immutable ownership data stored on the blockchain and mutable metadata stored in a decentralized database. The blockchain stores only the hash of the metadata, ensuring ownership reliability, while the decentralized database allows dynamic metadata updates, resolving the contradiction between immutability and adaptability.
Solution Approach 2:
The patent introduces a decentralized database as an intermediary between the blockchain and the metadata. This intermediary layer allows metadata to be updated dynamically while the blockchain maintains secure, immutable ownership records through hash verification, enabling both reliability and versatility.
2Reliability
If NFTs use traditional immutable storage, then data integrity is maintained, but user engagement and interactive capabilities are limited
Solution Approach 1:
The patent makes NFT metadata dynamic by storing it in a decentralized database that allows updates, while the blockchain maintains static, immutable ownership records. This dynamic storage approach enables users to modify metadata (improving ease of operation) while the blockchain's immutable hash verification ensures data integrity is maintained.
3Reliability
If NFTs store complete media files on blockchain, then ownership proof is comprehensive, but storage cost and system complexity increase significantly
Solution Approach 1:
The patent extracts the large media file data from the blockchain storage and stores it in external decentralized storage systems, while the blockchain retains only the cryptographic hash of the media file. This extraction approach maintains complete ownership proof through hash verification while dramatically reducing blockchain storage requirements and system complexity.
4Ease of manufacture
If NFTs use centralized metadata storage, then updates are easy to implement, but the system becomes vulnerable to link rot and single points of failure
Solution Approach 1:
The patent introduces a decentralized database as an intermediary for metadata storage, which maintains the ease of updating metadata while distributing the storage across multiple nodes to eliminate single points of failure and prevent link rot, thus improving both ease of manufacture and reliability.
Data Source
AI summary
A system to perform operations that include: accessing a data object that comprises an Augmented-Reality (AR) filter; accessing a blockchain based on the accessing the data object; minting a Non-Fungible Token (NFT) based on the data object and the blockchain; and storing the NFT on the blockchain.
