Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If blockchain technology is used for decentralized control systems, then security and immutability are improved, but the ability to implement logic gate functionality is insufficient

Engineering Contradiction:
ImprovesecurityVSAvoidlogic gate functionality
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements logic gate functionality within blockchain transactions by encoding Boolean operations in locking and unlocking scripts. This allows blockchain to serve multiple purposes: maintaining its security and immutability while simultaneously performing logic gate operations for decentralized control systems, thus achieving multi-functionality without compromising its core strengths.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If complex control systems are implemented using blockchain, then cybersecurity and immutability are enhanced, but system complexity increases

Engineering Contradiction:
ImprovecybersecurityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent enables blockchain transactions to self-evaluate their own validity through embedded locking and unlocking scripts that contain logic gate functionality. The system automatically performs Boolean operations and condition evaluations without requiring external control logic, allowing complex control systems to be implemented while maintaining security and reducing the need for additional centralized management infrastructure.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If logic gate functionality is added to blockchain transactions, then adaptability for control systems is improved, but transaction validation complexity increases

Engineering Contradiction:
Improvecontrol system applicationVSAvoidtransaction validation
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges logic gate functionality directly into the existing blockchain transaction structure by embedding Boolean operations within locking and unlocking scripts. This integration allows control system logic to be executed as part of the standard transaction validation process, enabling adaptability for control systems while utilizing the existing validation infrastructure rather than creating separate complex validation mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The invention presents a solution in which blockchain transactions are created to implement the functionality of a logic gate. The invention may be implemented on the Bitcoin platform or an alternative blockchain platform. The transaction includes a locking script which comprises instructions to process Boolean inputs and implement the functionality of a logic gate, such as the XOR gate. When the script is executed, the inputs will be evaluated, using computing agents, to provide an output of TRUE or FALSE, and the output will be subsequently provided to an unlocking script associated with a second transaction attempting to spend the output associated with the locking script. The second transaction is transmitted to the blockchain network for validation and, if determined to be valid (evaluated to a TRUE output), it will be written to the blockchain. Thus, the locking script of the first transaction provides the functionality.
