Digital Currency Conversion Using Offline Legitimacy Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital currency management systems face challenges in efficiently converting and managing digital currencies issued by different management mechanisms, leading to inefficiencies in circulation and transaction convenience.
Innovation Solution
A digital currency management method and system that enables direct conversion of digital currencies belonging to different management systems by a first currency management apparatus, generating equivalent digital currencies for a client without requiring real-time verification from the original systems, while ensuring legitimacy through offline verification and transaction monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital currencies from different management mechanisms are converted through traditional methods, then the legitimacy and security of currency conversion is ensured, but the conversion speed and circulation efficiency deteriorate
Solution Approach 1:
The system performs preliminary verification of digital currency legitimacy before conversion by checking circulation identifiers and transaction vouchers in advance. This allows the conversion process to proceed rapidly without requiring real-time verification during the actual conversion, thus maintaining security while improving speed.
Solution Approach 2:
The patent introduces an intermediary verification mechanism where the second currency management apparatus validates the authenticity of first digital currencies from different management mechanisms through circulation identifiers and transaction vouchers. This intermediary layer ensures security without requiring direct real-time communication between all currency management systems during conversion.
2Measurement precision
If real-time verification with original currency management systems is performed, then the accuracy of currency validation is improved, but the transaction time and system complexity worsen
Solution Approach 1:
The system performs validation checks in advance by verifying circulation identifiers and transaction vouchers before the actual conversion process. This preliminary validation ensures accuracy while allowing the subsequent conversion to proceed without time-consuming real-time verification, thus reducing overall transaction time.
Solution Approach 2:
The patent uses circulation identifiers and transaction vouchers as copies or representations of the original currency validation data. These copies contain sufficient information to verify currency legitimacy without requiring access to the original currency management systems during the conversion process, thereby maintaining validation accuracy while reducing transaction time.
3Adaptability or versatility
If multiple currency management mechanisms are integrated for conversion, then the versatility and adaptability of the system is improved, but the device complexity and verification difficulty worsen
Solution Approach 1:
The system achieves multi-system compatibility by using universal verification elements such as circulation identifiers and transaction vouchers that can validate digital currencies from different currency management mechanisms. The second currency management apparatus can handle conversions from multiple first currency management apparatuses using the same verification approach, thus providing versatility without proportionally increasing complexity.
Solution Approach 2:
The patent verifies digital currencies by checking specific parameters such as circulation identifiers and transaction vouchers rather than requiring complex integration with each individual currency management system. By focusing verification on these key parameters, the system can accommodate multiple currency mechanisms while keeping the verification process relatively simple and manageable.
4Reliability
If traditional digital currency conversion methods are used, then the security against double payments is maintained, but the circulation liquidity and transaction convenience deteriorate
Solution Approach 1:
The system performs preliminary checks of circulation identifiers and transaction vouchers to prevent double payments before the conversion process. This advance verification ensures that the same digital currency cannot be converted multiple times while allowing legitimate conversions to proceed rapidly, thus maintaining security against double payments while improving circulation liquidity.
Solution Approach 2:
The patent implements a feedback mechanism where the second currency management apparatus verifies transaction vouchers and circulation identifiers to confirm that the digital currency has not been previously spent or converted. This feedback loop ensures double payment prevention while enabling rapid conversion processing that maintains circulation liquidity.

AI summary
The disclosure relates to the technical field of computers. Disclosed are a digital currency management method, apparatus and system. A specific implementation of the method includes: sending one or more first digital currencies to a first currency management apparatus corresponding to a first client, where the one or more first digital currencies belong to one or more second currency management apparatuses different from the first currency management apparatus; and receiving a second digital currency, which is generated by the first currency management apparatus according to the one or more first digital currencies, where the denomination of the second digital currency is equal to the sum of denominations of the one or more first digital currencies.
