NFT Digital Asset Tracking via Blockchain History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video games lack an efficient method to track and validate the history and ownership of digital assets, leading to potential fraud and misrepresentation, and restrict the use of digital assets across different games.
Innovation Solution
The implementation of non-fungible tokens (NFTs) using blockchain technology to create unique digital identifiers for digital assets, tracking their ownership, usage history, and allowing portability across different video games.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional digital asset tracking methods are used in video games, then the system complexity is low, but the reliability of ownership validation and history tracking is poor
Solution Approach 1:
The patent introduces a blockchain-based NFT system as an intermediary layer between the video game and digital assets. The NFT acts as a mediator that stores and validates ownership information and usage history on the blockchain, rather than relying solely on the game's internal database. This intermediary structure ensures tamper-proof tracking of asset ownership and history, resolving the contradiction by prioritizing reliability through the addition of blockchain technology.
Solution Approach 2:
The patent replaces the traditional centralized database mechanism (mechanical system) with a decentralized blockchain mechanism. Instead of storing asset ownership and history in a game server database that can be modified or corrupted, the system uses blockchain's cryptographic hashing and distributed ledger technology to store NFT data. This substitution fundamentally improves ownership validation reliability by making the system immutable and transparent, while the added complexity is offset by the automated nature of blockchain operations.
2Adaptability or versatility
If digital assets are confined to single video games, then the ease of operation is high, but the adaptability of digital assets is limited
Solution Approach 1:
The patent creates a universal NFT standard that can represent digital assets across multiple video games and platforms. The NFT structure includes standardized metadata fields (asset identifier, owner address, game identifier, usage history) that can be interpreted by different games. This allows a single NFT to function across multiple games, enabling asset portability and inter-game trading while maintaining tracking simplicity through the standardized NFT format.
Solution Approach 2:
The patent adds a new dimension to digital asset management by introducing the blockchain layer above the traditional game database layer. This dimensional addition allows assets to exist in two states simultaneously: game-specific usage context and blockchain-verified ownership history. The NFT bridges these dimensions, enabling assets to be tracked across games (portability) while the blockchain automatically handles the complexity of cross-game tracking, reducing the burden on users.
3Loss of information
If comprehensive usage history is tracked for digital assets, then the loss of information is minimized, but the device complexity increases
Solution Approach 1:
The patent segments the digital asset tracking system into distinct components stored in the NFT: asset identifier, current owner address, game identifier, and usage history array. Each segment serves a specific function and can be independently managed. The usage history itself is segmented into individual usage records, each containing timestamp, asset used, and event type. This segmentation allows comprehensive tracking while maintaining data structure clarity and enabling efficient querying of specific information without processing the entire dataset.
Solution Approach 2:
The patent uses cryptographic hashing to create compact representations of usage history data. Instead of storing full detailed records of every asset interaction, the system generates hash values that represent the usage history concisely. These hash copies serve as verified summaries that minimize data storage requirements while preserving the integrity and completeness of the original usage information, thus reducing data structure complexity while preventing information loss.
Data Source
AI summary
Methods and systems for tracking a game asset used in a video game includes generating a non-fungible token for the game asset used in the video game. Use of the game asset in the video game is monitored during gameplay to identify a qualifying event occurring in the video game in which the game asset is used. The NFT is updated using metadata associated with the qualifying event. The metadata is used to build legacy of the game asset and to track use of the digital asset in the video game.
