Engineering Contradiction Analysis
1Reliability
If quantum computing is used to solve mathematical problems, then cryptographic security is compromised, but using traditional algorithms provides security against standard computers
Solution Approach 1:
The patent transitions from using mathematical problem-based cryptography (RSA, ECDSA) to hash-based cryptography. This fundamental parameter change in the cryptographic approach creates a system that is resistant to quantum computing attacks while maintaining security against classical computers, as hash functions do not rely on the mathematical problems that quantum algorithms like Shor's algorithm can solve efficiently.
2Reliability
If traditional hash-based signatures are used, then quantum resistance is achieved, but data sizes become impractical
Solution Approach 1:
The patent extracts only the essential hash values from traditional hash-based signature schemes and stores them in a blockchain. Instead of storing complete signature structures with large data sizes, the system stores compact hash values (e.g., SHA-256 producing 256-bit hashes) that can be efficiently verified, dramatically reducing the quantity of data while maintaining quantum resistance.
Solution Approach 2:
The blockchain structure serves multiple functions: it stores the hash values for quantum-resistant verification, provides immutable timestamps for the values being protected, and enables efficient retrieval and verification by any participant. This multi-functionality eliminates the need for separate signature storage structures, reducing overall data requirements.
3Reliability
If complex mathematical algorithms are used, then security against standard computers is maintained, but computational efficiency decreases
Solution Approach 1:
The patent replaces complex mathematical algorithm computations (factorization, discrete logarithms) with hash function computations. Hash functions are computationally more efficient, requiring fewer computational resources and time to generate and verify, while providing adequate security for the application's needs. This substitution improves productivity without significantly compromising security.

AI summary
A method for moderation in a permissioned blockchain using a hash-oriented scheme includes: storing a blockchain including a most recent block; receiving transaction data values; receiving a first reference value and a second reference value; generating a first hash value by hashing the first reference value; generating a block proof including the first hash value, a second hash value, a third reference value, and a block value; verifying a block header of the most recent block using the block proof; receiving a new block value; generating a new block header including the first reference value, the second reference value, a fourth reference value, and the new block value; generating a new block for the blockchain including the new block header and the transaction data values; and transmitting the new block to one or more additional nodes associated with the blockchain.
