NFT Attribute Cards for Off-Chain Game Progression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional NFTs pose challenges for traditional gaming by limiting the use case of 'game collectibles' backed on a blockchain, as players desire to keep game items even after game servers are shut down, and existing game progression models require significant computational load for coincident level progression events.
Innovation Solution
Implementing off-chain electronic games with blockchain-verified ownership of in-game assets using NFT attribute cards for attribute upgrades, leveraging on-chain cryptographic assets to manage ownership and authorization, and employing smart contracts to control NFT usage across games, thereby reducing computational load and enabling flexible digital art design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional NFTs are used for game collectibles, then ownership can be transferred and traded, but players cannot retain game items after game servers are shut down
Solution Approach 1:
The patent segments the game system into off-chain game assets (stored on blockchain) and on-chain verification (ownership records). This separation allows game items to exist independently of game servers, with ownership verified through blockchain technology rather than centralized server storage.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary between players and game assets. Instead of relying on game servers to store and verify ownership, the blockchain acts as a decentralized mediator that permanently records asset ownership, enabling players to retain items even when servers are shut down.
2Adaptability or versatility
If traditional NFT business model is used, then NFTs can be sold and traded, but it limits the use case of game collectibles
Solution Approach 1:
The patent makes NFTs universal by enabling them to function both as tradeable collectibles and as game progression assets. The same NFT can be used for leveling up characters, unlocking game features, or traditional trading, expanding the versatility of game collectibles beyond单一的交易用途.
3Reliability
If game progression events are processed on-chain, then ownership verification is secure, but computational load increases significantly
Solution Approach 1:
The patent extracts the computationally intensive game progression processing from the blockchain and moves it to off-chain game systems. Only essential ownership verification and asset transfer operations remain on-chain, significantly reducing computational load while maintaining security through blockchain verification of critical operations.
Data Source
AI summary
A computer system operates an off-chain electronic game that includes in-game assets stored off of a blockchain. The off-chain electronic game is configured to incorporate on-chain cryptographic assets related to in-game leveling or progression. In some examples, the on-chain cryptographic assets are non-fungible tokens (NFTs), and the on-chain cryptographic assets define in-game attribute data and can include generic digital and visual art. The computer system obtains permission from an interoperability API of a gaming environment/platform to apply a given on-chain cryptographic asset to an in-game asset to modify attribute data of the in-game asset. The computer system applies the given on-chain cryptographic asset and provides an in-game visual indication of the application and modification of attribute data. The in-game visual indication includes a combination of game-specific digital art and the generic digital art of the given on-chain cryptographic asset.
