Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blockchain systems face inefficiencies in multi-echelon supply chain traceability queries due to growing data storage overheads and the difficulty in ensuring completeness and consistency across separate blockchains, limiting the ability to execute cross-chain transactions effectively.
Innovation Solution
A method utilizing a pluggable sub-blockchain system (PSB) and system relationship blockchain (SRB) for multi-chain data association, ensuring intra-chain and cross-chain consistency through chronological ordering and dependency recording, allowing for parallel query execution across multiple chains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If more transaction data are stored in a blockchain to ensure completeness, then data completeness is improved, but query efficiency deteriorates due to association among given transaction data decreasing
Solution Approach 1:
The patent divides the blockchain into multiple independent chains, each storing only relevant transaction data for specific supply chain segments. This segmentation reduces the data volume each chain needs to maintain while ensuring completeness within its scope, thereby improving query efficiency without sacrificing overall data completeness.
Solution Approach 2:
The patent introduces a cross-chain query mechanism that acts as an intermediary between different blockchain chains. This mediator coordinates queries across multiple chains, allowing efficient retrieval of related transactions without requiring full scans of all chain data, thus maintaining completeness while improving efficiency.
2Adaptability or versatility
If data are distributed across multiple blockchains to enhance scalability, then system scalability is improved, but query completeness deteriorates due to independent data distribution
Solution Approach 1:
The patent designs a universal query mechanism that can operate across multiple independent blockchain chains. This multi-functional query system maintains the ability to query any chain while ensuring completeness by coordinating across chains, thus preserving scalability without compromising query completeness.
Solution Approach 2:
The patent implements feedback mechanisms where query results from different chains are aggregated and verified. This feedback loop ensures that all relevant data from distributed chains are collected and cross-checked, maintaining query completeness while preserving the scalability benefits of distributed data storage.
3Reliability
If cross-chain transaction verification is implemented to ensure consistency, then data consistency is improved, but system complexity increases due to multiple signatures required
Solution Approach 1:
The patent merges the verification functions across multiple chains into a coordinated query mechanism. Instead of requiring multiple separate signatures for cross-chain transactions, the system combines verification logic into a unified process that maintains consistency while reducing the apparent complexity through centralized coordination.
Solution Approach 2:
The patent introduces a cross-chain coordination mechanism that acts as an intermediary for transaction verification. This mediator handles the complexity of multi-signature verification and cross-chain consistency checks, presenting a simplified interface to users while ensuring data consistency across chains.

AI summary
The present invention relates a method for high-performance traceability query oriented to multi-chain data association, comprising: identifying a target transaction needing the traceability query; searching out all corresponding target chains based on cross-chain transaction data association; making query requests parallelly; and executing the query among the target chains according to a key value of the target transaction and returning query results. The blockchain traceability query method proposed by the present invention is different from serialized block data query conducted in the chain-type structure, and the disclosed cross-chain query operation can be parallelly executed, leading to improved efficiency of traceability query. Opposite to the conventional blockchain where blocks are used as nodes of chains, the present invention directly uses sub blockchains as nodes of the SRB. Since sub blockchains can be dynamically added or removed, the present invention enhances the scalability of the entire system.
