Secure Digital Currency Service Unit for Separate Blockchain Smart Contracts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital currency systems face challenges in balancing flexibility, security, and performance, particularly in account-based and token-based systems, where ownership transfer and smart contracts are not optimally integrated, and collateral confirmations are complex and outdated.
Innovation Solution
A secure digital currency service unit with a separate blockchain structure that includes a digital currency wallet and a creation unit for smart contracts, managing digital currency assets as collateral, allowing flexible assignment to dedicated accounts while maintaining security and enabling smart contract functionality without altering the underlying system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If smart contracts are integrated into the digital currency system, then flexibility is improved, but security may be compromised
Solution Approach 1:
The system is divided into two independent parts: the digital currency system and the blockchain structure with smart contracts. They communicate through an interface without direct integration, allowing each system to maintain its security while enabling smart contract functionality.
Solution Approach 2:
A service unit acts as an intermediary between the digital currency system and the blockchain structure. It manages digital currency assets, handles collateral confirmations, and facilitates communication between the two systems without requiring changes to either system's core security architecture.
2Reliability
If a separate blockchain structure is used for smart contracts, then security is maintained, but device complexity increases
Solution Approach 1:
The service unit performs multiple functions: managing digital currency assets, creating and managing smart contracts, handling collateral confirmations, and interfacing with both the digital currency system and blockchain structure. This consolidates complexity into a single multi-functional component.
Solution Approach 2:
The blockchain structure operates independently with its own smart contract protocol and digital currency assets. It serves itself without requiring changes to the underlying digital currency system, reducing the complexity burden on the core system.
3Adaptability or versatility
If digital currency assets are managed in the blockchain structure, then flexibility is improved, but loss of time may increase due to collateral confirmation processes
Solution Approach 1:
Collateral confirmations are obtained in advance before smart contract transactions are executed. The service unit proactively manages collateral digital currency and obtains confirmations beforehand, eliminating delays during actual transactions.
Solution Approach 2:
The service unit continuously manages digital currency assets and maintains collateral confirmations as an ongoing process rather than a discrete step. This ensures that collateral validation is always current and ready for immediate use.
