Solution Overview

Problem

Traditional video games lack the ability to differentiate and authenticate unique digital assets, such as in-game items or characters, as they are typically fungible and lack a history tracking mechanism.

Innovation Solution

The implementation of a system using a distributed ledger to create and manage unique digital assets by generating a unique token with a unique identifier and metadata, allowing for the tracking of changes in ownership, visual appearance, and other properties, and storing this history across multiple devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional fungible digital assets are used in video games, then ease of operation and simplicity are maintained, but the ability to differentiate and authenticate unique digital assets is lost

Engineering Contradiction:
Improveauthentication capabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a distributed ledger as an intermediary system between the video game and digital assets. This mediator tracks and authenticates asset history without requiring complex verification mechanisms within the game itself. The ledger stores immutable records of asset creation, ownership transfers, and modifications, providing reliable authentication while keeping the game system relatively simple.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a digital copy or representation of the asset's history on the distributed ledger. Instead of storing complex authentication data directly in the game, the system maintains a simplified reference copy of asset provenance on the blockchain, which can be verified without adding complexity to the game's core mechanics.

Inventive Principle:
Principle #26Copying

2Reliability

If a distributed ledger is implemented to track digital asset history, then unique asset differentiation and authentication are enabled, but device complexity and storage requirements increase

Engineering Contradiction:
Improveasset history trackingVSAvoidledger implementation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the asset tracking system into distinct components: the video game itself, the distributed ledger for history tracking, and the token representation of assets. This segmentation allows each component to remain relatively simple while the system as a whole provides comprehensive asset differentiation and authentication capabilities.

Inventive Principle:
Principle #1Segmentation

3Loss of information

If unique tokens with metadata are created for each digital asset, then asset uniqueness and traceability are achieved, but data storage requirements and processing complexity increase

Engineering Contradiction:
Improveasset provenance informationVSAvoiddata storage volume
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential provenance information needed for asset authentication and stores it on the distributed ledger. Instead of storing complete asset data or extensive metadata, the system captures key events (creation, ownership transfers, modifications) in a condensed format, reducing storage requirements while maintaining the ability to trace asset history.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A system and method for tracking digital assets associated with video games. The digital assets may be in-game digital assets, such as in-game items or characters. The digital assets may be video game digital media assets representing moments of gameplay of a video game, such as video clips or images. The digital asset is created, and a distributed ledger tracking a history of the digital asset is created and stored across devices. A unique token for the digital asset can include a unique identifier and metadata identifying properties of the digital asset. Changes to properties of the digital asset, such as ownership, visual appearance, or metadata, can be identified in a request to update the history. A new block can be generated for, and appended to, the distributed ledger identifying the changes to the history of the digital asset. The new block can include hashes of previous blocks.
