Cross-Chain Asset Transfer Across Independent Blockchains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In transferring a digital asset from one blockchain to another, the asset determining rules on different blockchains often result in differing digital assets, leading to security risks due to inconsistencies.
Innovation Solution
A method and apparatus for cross-chain asset transfer involving multiple blockchains, utilizing a full-chain asset transfer request, contract protocol interface, and off-chain cross-chain service device to ensure consistent asset data across chains, employing full-chain and remote service contracts to synchronize asset information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If asset determining rules are applied independently on each blockchain, then each blockchain can operate autonomously, but the mapping asset determined on the destination blockchain differs from the original asset, causing security risks
Solution Approach 1:
The patent introduces a cross-chain service device as an intermediary between independent blockchains. This device includes a determination module that coordinates asset mapping across chains, ensuring that the mapping asset on the destination blockchain consistently corresponds to the original asset on the source blockchain, while preserving blockchain autonomy
Solution Approach 2:
The cross-chain service device implements universal asset determination logic that can operate across multiple different blockchains. The determination module uses unified determination rules to identify corresponding assets on different chains, enabling consistent asset mapping across diverse blockchain systems with different native asset rules
2Adaptability or versatility
If different asset determining rules are used on different blockchains, then each blockchain can maintain its own characteristics, but the mapping asset and original asset become different digital assets, leading to security risks
Solution Approach 1:
The cross-chain service device acts as a mediator that reconciles different asset determining rules across independent blockchains. The determination module coordinates between chains with different rules, ensuring that despite rule differences, the mapping asset consistently corresponds to the original asset, thereby eliminating security risks while preserving blockchain independence
Solution Approach 2:
The patent dynamically adjusts asset determination parameters based on the specific blockchain context. The determination module modifies determination rules according to the source and destination blockchain characteristics, enabling consistent asset mapping across blockchains with different native asset parameters and rules

AI summary
A data processing method based on multiple blockchains is disclosed, the multiple blockchains including a first blockchain and a second blockchain, and the method being performed by a computer device maintaining a first blockchain node in the first blockchain network and including: receiving an cross-chain asset transfer request, which includes a cross-chain asset transfer transaction used to instruct to transfer the to-be-transferred full-chain asset from the first blockchain to the second blockchain (S101); and transferring the full-chain asset accordingly.
