Inter-system Linking via Dedicated Blockchain for Deduplication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inter-blockchain (BC) linking technologies face challenges in ensuring transparency of processing and avoiding single confidence points, leading to potential duplication and redundant processing when linking between BC systems or with non-BC systems.
Innovation Solution
An inter-system linking method where nodes manage identification information for call processing and execute deduplication based on specific policies to prevent duplication, ensuring that each processing request is executed only once across multiple BC systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a linking system is constructed separately from the BC system to monitor state changes and execute processing, then the linkage between BC systems can be realized, but the transparency of the processing cannot be secured
Solution Approach 1:
The patent introduces a dedicated linking BC as an intermediary system that mediates between multiple BC systems. This linking BC contains smart contracts that transparently record and execute the linkage processing logic, allowing all participants to verify the processing while maintaining system independence. The intermediary approach resolves the contradiction by providing both linkage capability and processing transparency through the use of a specialized mediator system.
2Adaptability or versatility
If a node outside the BC system is used to call each BC by referring to linking BC information, then linkage between BC systems can be achieved, but the node becomes a single confidence point and single failure point
Solution Approach 1:
The patent segments the linkage functionality into distributed smart contracts deployed across multiple nodes within the linking BC system, rather than relying on a single external node. Each node in the linking BC can independently verify and execute linkage operations, eliminating the single point of failure. This segmentation approach maintains inter-BC communication capability while significantly improving system reliability through distribution.
3Loss of information
If the same processing is executed by mutual verification properties of SC in each node of the calling source BC, then transparency is maintained, but duplicated processings occur resulting in wrong processing results
Solution Approach 1:
The patent implements a preliminary action mechanism where smart contracts in the linking BC pre-record the identification information of calling processing in advance. Before executing any linkage operation, the system checks whether the processing has already been executed by comparing against this pre-recorded information. This preliminary verification prevents duplicate processing while maintaining transparency, as all nodes can verify the uniqueness of processing through the publicly accessible smart contract records.

AI summary
A method includes: determining presence or absence of duplication processing by a node 1000, the node constituting each of a plurality of distributed ledger systems and managing identification information of call processing from a program on another distributed ledger system 1; and executing the call processing after deduplication of the call processing is executed based on a specific policy.
