Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data sharing methods based on blockchain fail to meet the complex sharing requirements of multi-party collaborative scenes involving industrial blockchain, Internet of Things, and industrial Internet, leading to inefficient and inaccurate data tracking across different service chains.
Innovation Solution
A multi-chain shared network structure is created, comprising a service chain, service system, and cross-chain router, with shared data and cross-chain link structures being stored and queried through the cross-chain router, utilizing shared data item identifiers, information fields, and cross-chain link fields to enable efficient and trusted data sharing and tracing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single-chain mode is used for data sharing, then the system structure is simple, but it cannot meet complex multi-party collaborative sharing requirements
Solution Approach 1:
The patent divides the blockchain system into multiple independent chains (industrial chain, supply chain, trade chain, finance chain) that can operate autonomously while maintaining data sharing capabilities. Each chain handles specific business scenarios, allowing the system to meet complex multi-party collaborative requirements without requiring a single monolithic structure.
Solution Approach 2:
The patent creates a multi-chain shared network structure that provides universal data sharing capabilities across different business domains. The shared network layer enables multiple chains to access and share data according to their specific needs, making the system adaptable to various data sharing scenarios while maintaining structural simplicity through modular design.
2Quantity of substance
If master-slave chain mode is used for data sharing, then the data sharing scale is large, but the requirements for applicable scenes are high
Solution Approach 1:
Instead of using a master-slave architecture where one chain dominates, the patent segments the system into multiple peer chains with equal status. Each chain can independently manage its data while participating in the shared network, reducing the applicability requirements compared to master-slave mode while maintaining large-scale data sharing capabilities.
Solution Approach 2:
The patent implements a dynamic multi-chain structure where chains can be added, removed, or modified based on specific business needs. This dynamic architecture allows the system to scale data sharing flexibly without requiring high applicability requirements, as each chain can be independently configured and activated according to actual demands.
3Adaptability or versatility
If multi-chain mode is used for data sharing, then digital asset cross-chain transfer is supported, but data sharing in multi-party collaborative complex scenes cannot be accurately and efficiently backtracked
Solution Approach 1:
The patent introduces a shared network layer as an intermediary between multiple chains. This shared network maintains cross-chain link structures that record data sharing relationships and provenance information. When data is shared across chains, the shared network tracks the data flow and maintains reference relationships, enabling accurate and efficient backtracking of data sharing operations while preserving cross-chain transfer capabilities.

AI summary
A data sharing method and a data sharing apparatus based on a blockchain are provided, aiming to solve the problem that the existing data sharing cannot meet the sharing requirement of a multi-party collaborative complex scene of combining an industrial blockchain, an Internet of things and an industrial Internet, which relates to the technical field of the blockchain technology. The method includes: creating a multi-chain shared network structure matched with a target service scene, creating shared data and cross-chain link structure of original data, and storing the shared data and cross-chain link structure on the service chain through the cross-chain router; and when the service system sends a query transaction of a target service chain through the cross-chain router, querying a target shared data and cross-chain link structure of the target service chain, and further querying the linked shared data and cross-chain link structure of the linked service chain.
