Blockchain Asset Transfer Trust Limit Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing asset transfer methods in blockchain networks lack effective mechanisms to manage trust limits between blockchain members and anchors, leading to potential asset loss risks due to untrusted anchors.
Innovation Solution
Implementing a method that detects asset transfer requests, determines if a maximum trusted asset limit exists for the specified anchor, and prohibits the transfer if the limit does not exist, ensuring that asset transfers only occur within trusted limits configured by blockchain members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If asset transfer is allowed without checking maximum trusted asset limit, then asset transfer efficiency is improved, but security and reliability deteriorate due to potential asset loss from untrusted anchors
Solution Approach 1:
The system performs preliminary verification by checking whether a maximum trusted asset limit is configured for the anchor before allowing asset transfer. This advance check prevents transfers to untrusted anchors, resolving the contradiction by ensuring security measures are in place before the transfer operation commences.
2Reliability
If maximum trusted asset limit verification is performed for all asset transfers, then security is improved, but system complexity increases
Solution Approach 1:
Blockchain members autonomously configure their own maximum trusted asset limits for different anchors based on their trust assessments. The system automatically checks these pre-configured limits during asset transfer operations. This self-service approach reduces system complexity by eliminating the need for centralized trust management while maintaining security through automated limit verification.
3Object-affected harmful factors
If maximum trusted asset limit is configured for each anchor and asset type, then asset loss risk is reduced, but ease of operation deteriorates due to additional configuration requirements
Solution Approach 1:
The system manages complexity by parameterizing trust limits according to different anchors and asset types, allowing flexible configuration of maximum trusted asset limits. This parameter-based approach enables precise control over asset transfer risks while maintaining operational simplicity through structured limit management.

AI summary
One or more implementations of the present specification provide an asset transfer method and apparatus and an electronic device, which are applied to a blockchain node. The method includes the following: An asset transfer request related to a blockchain member is detected, where the asset transfer request involves transferring an asset of a specified asset type to an asset held by the blockchain member, and the asset to be transferred is issued by a specified anchor in a blockchain. A determination is performed as to whether there is a maximum trusted asset limit that is configured by the blockchain member for the specified anchor and that corresponds to the specified asset type. The asset transfer request is prohibited when the determination is that the maximum trusted asset limit does not exist.
