Secure Transaction Controller for Value Token Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cash systems face scalability issues, security risks due to compromised signature keys, interoperability problems, and performance bottlenecks, particularly in double spending checks, and struggle with anonymity and regulatory compliance.
Innovation Solution
A system that uses cryptographically signed digital tokens, with a processor managing Value Tokens, including secure memory for private keys, to validate and swap tokens, ensuring secure and scalable transactions while maintaining auditability and anonymity, and enabling flexible exchange of different token types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cryptographic digital signatures are used for token validation, then security is improved, but performance bottleneck occurs in double spending checks
Solution Approach 1:
The system divides the token validation process into two independent parts: cryptographic signature validation (for security) and double spending check (for preventing reuse). These are performed as separate operations, allowing the cryptographic validation to be done locally and efficiently while the double spending check is handled through a different mechanism (timestamp-based or registry-based), thus resolving the performance bottleneck caused by combining both checks.
2Reliability
If centralized ledger-based systems are used, then double spending prevention is improved, but scalability and interoperability deteriorate
Solution Approach 1:
The patent introduces an optional intermediary component (such as a timestamp authority or registry service) that mediates between the cryptographic token system and the double spending prevention mechanism. This intermediary allows tokens to be validated without requiring a centralized ledger, enabling scalable and interoperable systems while still preventing double spending through the intermediary's coordination.
3Ease of operation
If anonymous tokens are used, then user privacy is improved, but regulatory compliance and auditability deteriorate
Solution Approach 1:
The system dynamically adjusts the anonymity level of tokens based on regulatory requirements and transaction context. Tokens can be issued with different privacy properties (fully anonymous, partially anonymous, or fully traceable) depending on the jurisdiction, transaction type, and compliance needs. This dynamic approach allows the system to maintain user privacy where appropriate while ensuring auditability where required by regulations.
