Blockchain Capital Chain Traceability via Consensus Linking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for tracing capital chain information on third-party payment platforms are inefficient due to storage time limits and resource consumption, despite the importance of this information for risk control and other purposes.
Innovation Solution
A computer-implemented method using a blockchain system to record and retrieve capital change information, where capital changes are recorded based on a consensus mechanism and linked by timeline or participants, allowing for efficient querying of capital chain information through a network of blockchain nodes corresponding to transaction locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If capital chain information is stored on a third-party payment platform for a limited period, then storage space is saved, but the information becomes unavailable after the time limit expires
Solution Approach 1:
The system segments the storage function by separating the payment platform from the blockchain storage system. The payment platform handles transaction processing while the blockchain system independently stores capital chain information indefinitely, resolving the conflict between limited storage space and long-term information availability.
Solution Approach 2:
The blockchain system acts as an intermediary between the payment platform and the capital chain information storage. It receives and stores capital change information from the payment platform, ensuring information persistence beyond the payment platform's storage limitations while maintaining data integrity through consensus mechanisms.
2Ease of operation
If traditional methods are used to query capital chain information, then the query process is simple, but lots of time and resources are consumed
Solution Approach 1:
The blockchain system performs preliminary actions by pre-organizing capital chain information in blocks with timestamps and sequential relationships. This pre-structuring enables efficient querying through the account identifier index and time-range filtering, reducing the time and resources needed during actual query operations while maintaining simple user interaction.
3Speed
If capital chain information is stored centrally on the payment platform, then data access is fast, but the system is vulnerable to tampering and loss
Solution Approach 1:
The system merges the payment platform's transaction processing capability with the blockchain's distributed storage and consensus mechanism. Capital chain information is generated by the payment platform but stored and validated across multiple blockchain nodes, combining the speed of centralized transaction processing with the reliability of distributed storage for tamper-proof record-keeping.

AI summary
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for tracing capital chain information are provided. One of the methods, implemented by a computing device, includes: receiving a query request for querying capital chain information of a target account; parsing the query request to obtain an account identifier of the target account and a query condition; retrieving, based on the account identifier from a blockchain system, a plurality of pieces of capital change information of the target account meeting the query condition, wherein the plurality of pieces of capital change information of the target account are pre-recorded in the blockchain system based on a consensus mechanism; and obtaining the capital chain information by linking the plurality of pieces of capital change information based on information associated with a timeline or a plurality of participants associated with the pieces of capital change information.
