Cross-Blockchain Data Migration via Hash Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain data migration processes rely on third-party service organizations, leading to inefficiencies and security concerns due to the need for intermediaries.
Innovation Solution
A cross-blockchain data migration method that involves a first node in a first blockchain network converting service data information into a compatible format for a second blockchain network, establishing a hash mapping relationship, and migrating the data based on this relationship.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a third-party service organization is used to migrate ledger data between heterogeneous blockchains, then data migration can be achieved between different blockchain systems, but the migration process becomes complex and requires intermediary participation
Solution Approach 1:
The patent extracts and eliminates the third-party service organization from the data migration process. By enabling direct peer-to-peer data migration between heterogeneous blockchains through protocol compatibility layers, the system removes the intermediary component that previously added complexity to the migration process
Solution Approach 2:
The patent introduces a protocol compatibility layer as a lightweight intermediary mechanism that enables direct communication between heterogeneous blockchains. This mediator operates at the protocol level rather than requiring a full third-party service organization, thus reducing overall system complexity while maintaining adaptability
2Reliability
If a third-party service organization is used to migrate ledger data, then data migration can be performed, but security concerns arise due to intermediary involvement
Solution Approach 1:
The patent removes the third-party service organization from the migration architecture, eliminating the security risks associated with intermediary involvement. The system achieves secure direct migration between blockchains through cryptographic verification and consensus mechanisms
Solution Approach 2:
The patent enables blockchains to perform self-verification and self-validation during the data migration process through built-in consensus algorithms and cryptographic protocols. This self-service capability eliminates the need for external security intermediaries while maintaining high security standards
3Productivity
If traditional data migration methods are used through third parties, then data can be transferred between blockchains, but migration efficiency is reduced
Solution Approach 1:
The patent extracts the time-consuming intermediary processing steps from the migration workflow. By implementing direct peer-to-peer data transfer between blockchains with automated verification, the system eliminates the time loss associated with third-party service organization involvement
Solution Approach 2:
The patent performs preliminary actions by pre-establishing protocol compatibility layers and verification mechanisms before data migration begins. This preparation enables rapid direct migration without requiring time-consuming intermediary processing during the actual data transfer

AI summary
A cross-blockchain data migration method includes obtaining, by a first node in a first blockchain network, from a first blockchain in the first blockchain network, first service data information corresponding to a first data structure mode stored in a first block in the first blockchain and obtaining a second data structure mode associated with a second block in a second blockchain corresponding to a second blockchain network. The method further includes converting the first service data information to second service data information corresponding to the second data structure mode and establishing a hash mapping relationship between the first service data information and the second service data information in the first blockchain. The method also includes migrating the second service data information to a second node in the second blockchain network based on the hash mapping relationship.
