Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing blockchain asset transfer systems face challenges in reversing failed transactions, particularly when the payee's account is insufficient or frozen, leading to delays and increased costs due to the need for traditional reversal routes.

Innovation Solution

An asset transfer reversal processing method and apparatus that allows a first blockchain member to obtain assets from a second member, perform off-chain transfer-out operations, write transaction reversal applications onto the blockchain, and clear assets when transfer-out operations fail, ensuring reliable and efficient reversal processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional reversal routes are used for failed asset transfers, then transaction reversal can be achieved, but processing time increases and costs increase

Engineering Contradiction:

Improvetransaction reversal reliabilityVSAvoidreversal processing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by having the payer transfer assets to an intermediate blockchain member before the final payee receives them. This staged approach allows for easier reversal if the transaction fails, as the intermediate member already holds the assets and can initiate the reversal process immediately without waiting for traditional routing procedures.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

An intermediate blockchain member is introduced as a mediator in the asset transfer process. This intermediary holds assets temporarily and can facilitate reversals when transactions fail, reducing the time and complexity of traditional reversal routes by having a pre-positioned intermediary ready to handle the reversal rather than routing back through multiple traditional channels.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If traditional reversal routes are used for failed asset transfers, then transaction reversal can be achieved, but processing costs increase

Engineering Contradiction:

Improvetransaction reversal reliabilityVSAvoidreversal processing costs

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

Assets are preliminarily transferred to an intermediate member before final delivery, creating a staging point that reduces reversal costs. This preliminary positioning of assets eliminates the need for expensive traditional reversal routing through multiple financial institutions, as the intermediate member can directly reverse the transaction with minimal additional cost.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The intermediate blockchain member acts as a cost-effective mediator for reversals. By positioning an intermediary within the blockchain network rather than relying on traditional external reversal routes, the system reduces processing costs while maintaining reliability, as the intermediary is already part of the blockchain ecosystem and can reverse transactions efficiently.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If off-chain asset transfer operations are performed, then transfer speed improves, but security risks increase when transfers fail

Engineering Contradiction:

Improveasset transfer speedVSAvoidsecurity risks during failed transfers

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

An intermediate blockchain member serves as a secure mediator for off-chain asset transfers. This intermediary validates and secures the transfer process, reducing security risks when transfers fail. The intermediate member acts as a trusted third party that can verify transaction validity and facilitate secure reversals, mitigating the security risks inherent in faster off-chain operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback mechanisms where the intermediate blockchain member monitors off-chain transfer operations and can trigger reversal processes when failures are detected. This feedback loop ensures that security risks are managed by continuously monitoring the transfer process and automatically initiating corrective actions, allowing fast off-chain transfers while maintaining security through active oversight.

Inventive Principle:

AI summary

A blockchain asset that is transferred from a second blockchain member is received at a first blockchain member in response to an asset transfer request for transferring an asset between a payer and a payee, where the first blockchain member and the second blockchain member associated with a blockchain. In response to receiving the blockchain asset, an off-chain asset transfer-out operation for the payee is performed by the first blockchain member. If the off-chain asset transfer-out operation fails, a transaction reversal application for an asset transfer transaction corresponding to the asset transfer request is written into the blockchain by the first blockchain member. In response to writing the transaction reversal application, an asset clearing with the second blockchain member for an off-chain asset corresponding to the off-chain asset transfer-out operation is performed by the first blockchain member.
