Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional digital signature verification is used in blockchain transactions, then transaction processing is simple and fast, but the system becomes vulnerable to quantum computing attacks
Solution Approach 1:
The patent introduces a cryptographic hash function as an intermediary mechanism between the traditional digital signature verification and quantum-resistant requirements. The hash function transforms transaction data into a fixed-size hash value that serves as a quantum-resistant verification element, bridging the gap between simple verification and quantum security without requiring completely new verification protocols.
Solution Approach 2:
The verification process is segmented into multiple independent components: traditional digital signature verification, cryptographic hash computation, and commitment scheme validation. Each component can be implemented and verified separately, allowing the system to maintain simplicity in each individual step while achieving quantum resistance through their combination.
2Reliability
If cryptographic hash functions are used to generate pre-image values and obfuscated commit requests, then quantum resistance is achieved, but transaction processing time increases
Solution Approach 1:
The cryptographic hash values and commitment structures are computed and stored in advance during transaction creation, before the actual verification occurs. This preliminary computation allows the verification process to simply compare pre-computed hash values rather than performing complex hash computations during verification, significantly reducing the time loss while maintaining quantum resistance.
3Loss of information
If commit requests are obfuscated using commit output, then transaction privacy is improved, but verification difficulty increases
Solution Approach 1:
The verification mechanism incorporates feedback through the commitment scheme where the commit output provides verifiable information about the obfuscated transaction without revealing its contents. The system uses the commitment structure to provide feedback that confirms transaction validity while maintaining privacy, allowing verification without directly inspecting the obfuscated transaction data.

AI summary
Systems and methods for securing transactions in accordance with various embodiments of the invention are illustrated. One embodiment includes a method for confirming token ownership rights. The method generates a pre-image value using a random number generator. The method generates an action request that corresponds to an action performed cryptographic token(s). The method derives a commit output based on the pre-image value. The method generates a commit request that obfuscates the action request based on the commit output and submits the commit request to an immutable ledger. The method receives a confirmation when the commit request is approved by the ledger. When a reveal request referencing the commit output is published, the method receives a confirmation of at least one of: the reveal request being published, that the reveal request comprises a reference to the commit output, or that the action request has been approved.
