Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing blockchain systems lack a seamless method to bridge assets between different distributed ledgers while maintaining the features and provenance of the original assets, leading to disruptions in user experience and asset integrity.

Innovation Solution

The implementation of a Feature Portability Bridge (FPB) that freezes assets on the original ledger, creates a bridged asset on the target ledger, and maintains links to ensure that users can continue receiving features and provenance, allowing for asset transfer and visibility across ledgers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If assets are transferred between different distributed ledgers using traditional bridging methods, then asset mobility and accessibility across ledgers are improved, but asset integrity and feature preservation are compromised

Engineering Contradiction:

Improveasset mobility across ledgersVSAvoidasset integrity and feature preservation

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent creates a bridged asset that is a copy or representation of the original asset on the target ledger, maintaining the original asset's features and provenance through smart contract encapsulation. This copying mechanism allows asset mobility while preserving integrity, as the bridged asset replicates essential characteristics without altering the original.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent implements nesting by encapsulating the original asset's features, metadata, and provenance information within a smart contract structure that resides on the target ledger. The bridged asset contains nested layers of information including the original asset identifier, feature sets, and provenance data, allowing comprehensive feature preservation while enabling cross-ledger transfer.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If assets are locked on the original ledger to enable bridging, then asset transfer between ledgers is enabled, but user access and feature utilization on the original ledger are disrupted

Engineering Contradiction:

Improvecross-ledger asset transferVSAvoiduser access and feature utilization

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces a bridging smart contract as an intermediary that manages the locking and unlocking of assets during cross-ledger transfers. This intermediary mechanism coordinates between the original and target ledgers, enabling asset transfer while maintaining proper access controls and feature availability through structured lock/unlock operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent performs preliminary actions by pre-configuring the bridging smart contract with all necessary feature sets, metadata, and access rules before the actual asset transfer occurs. This preliminary setup ensures that when assets are locked for bridging, the user experience and feature access are minimally disrupted because the transfer mechanism is already prepared and validated.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If traditional asset bridging is implemented without feature preservation, then bridging simplicity and speed are improved, but user experience and asset functionality are degraded

Engineering Contradiction:

Improvebridging speed and simplicityVSAvoiduser experience and asset functionality

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent extracts essential feature sets, metadata, and provenance information from the original asset and incorporates them into the bridged asset's smart contract structure. This extraction process selectively transfers only the critical features needed for maintaining user experience and asset functionality, rather than copying the entire asset structure, thus balancing speed with functionality preservation.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements a universal bridging mechanism that can handle multiple asset types and feature sets through a single smart contract framework. This multi-functional approach allows the same bridging process to preserve diverse asset characteristics (NFT attributes, token metadata, provenance data) without requiring separate complex procedures for each asset type, thereby maintaining both speed and functionality.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A system described herein may receive a request to bridge an asset from a first distributed ledger to a second distributed ledger. The system may record, to the first distributed ledger, information indicating that the asset is frozen. The first distributed ledger may maintain information indicating that the frozen asset remains associated with an owner of the asset. The system may record, to the second distributed ledger, a bridged version of the asset, and may link the asset to the bridged asset. The system may identify a transfer of the bridged version of the asset to a second owner, and record, to the first distributed ledger and based on the linking of the asset to the bridged asset, information disassociating the first owner from the asset.
