Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cross-border payment systems face challenges in integrating heterogeneous financial systems, including data inconsistency, operational risks, and lack of a secure bridge for bidirectional value and data exchange, leading to lengthy processes and low credibility.
Innovation Solution
A transaction processing method and apparatus that utilizes an on-chain issuer node on a blockchain network to generate digital currency by deducting funds from off-chain local payment or digital currency systems, ensuring data consistency and trust through smart contracts and digital signatures, thereby establishing a trusted data channel between systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional cross-border payment systems use multiple intermediary agencies and clearing organizations, then transaction coverage is improved, but processing time increases and productivity decreases
Solution Approach 1:
The patent introduces a cross-domain transaction processing system that acts as an intermediary layer between heterogeneous financial systems. This system uses standardized protocols and interfaces to enable direct peer-to-peer transactions while maintaining compatibility with existing systems, thereby reducing the need for multiple intermediaries and clearing organizations.
Solution Approach 2:
The patent creates a universal transaction processing framework that can handle multiple types of transactions across different financial systems through a single standardized interface. This multi-functional system eliminates the need for separate processing paths for different transaction types, improving both coverage and efficiency.
2Adaptability or versatility
If conventional systems integrate heterogeneous financial systems, then system versatility is improved, but data consistency deteriorates due to lack of synchronized operations
Solution Approach 1:
The patent implements preliminary validation and commitment protocols before executing cross-domain transactions. The system performs pre-checks on transaction validity, reserves necessary resources, and establishes conditional commitments that ensure data consistency across systems before actual fund transfers occur, preventing inconsistent states.
Solution Approach 2:
The patent establishes feedback mechanisms between heterogeneous systems through the cross-domain processing platform. Transaction states, confirmations, and status updates are continuously exchanged between systems, ensuring that all parties have consistent view of transaction progress and enabling real-time reconciliation of data across different financial systems.
3Productivity
If blockchain-based systems are used to simplify processes, then productivity is improved, but integration with conventional financial infrastructure deteriorates due to system heterogeneity
Solution Approach 1:
The patent positions the cross-domain transaction processing system as an intermediary that bridges blockchain-based systems and conventional financial infrastructure. This mediator layer handles protocol translation, data format conversion, and compatibility issues, allowing blockchain systems to operate efficiently while maintaining seamless integration with existing financial systems.
Solution Approach 2:
The patent employs parameter adaptation mechanisms that dynamically adjust transaction parameters, data structures, and communication protocols based on the target system type. This allows the system to optimize for blockchain efficiency when appropriate while automatically adapting to conventional system requirements, maintaining both productivity and integration capability.
4Reliability
If atomic transaction operations are implemented across systems, then data consistency is improved, but system complexity increases due to verification requirements
Solution Approach 1:
The patent combines multiple verification functions into a unified cross-domain transaction processing system. By consolidating authentication, validation, commitment, and confirmation mechanisms into a single integrated platform, the system achieves atomic transaction operations across heterogeneous systems without proportionally increasing complexity, as the verification logic is centralized and standardized.
Data Source
AI summary
A transaction processing method, an apparatus, a device and a storage medium are provided. The technical solution of the present disclosure is as follows: receiving an issuing indication message sent by an off-chain transaction system, the issuing indication message comprising an off-chain participant identifier, a first target amount and a deduction success indication, and the deduction success indication being used for indicating that currency of the first target amount has been successfully deducted from a local bank account or a local digital currency wallet of the off-chain participant; and, in response to the issuing indication message, generating digital currency corresponding to the first target amount in a digital currency wallet of an on-chain participant node corresponding to the off-chain participant identifier of a block chain network.
