Engineering Contradiction Analysis
1Reliability
If traditional proof-of-work using computational power is used, then blockchain security is maintained, but energy consumption increases excessively
Solution Approach 1:
The patent replaces the computational/mechanical proof-of-work system with a physical printing system. Instead of using computational power to solve cryptographic puzzles, the system uses a printing device to physically print images with embedded number strings. The proof-of-work is transformed from a computational task to a physical manufacturing task, fundamentally substituting the mechanism while maintaining security requirements.
Solution Approach 2:
The patent changes the fundamental parameter of proof-of-work from computational complexity to physical manufacturing complexity. By requiring the printing device to physically produce images with specific number strings embedded in them, the system transforms the difficulty metric from CPU/GPU computational power to printing precision and physical resource consumption, thereby reducing energy consumption while maintaining security.
2Speed
If quantum computing power becomes available, then processing speed increases, but security of cryptocurrency is threatened
Solution Approach 1:
The patent replaces the computational proof-of-work system vulnerable to quantum computing with a physical printing-based system. The embedded number strings in printed images create a physical layer of security that is not susceptible to quantum computational attacks, as the security relies on physical manufacturing constraints rather than mathematical complexity that quantum computers could break.
3Reliability
If computational proof-of-work is used, then blockchain validation is achieved, but CO2 emissions increase
Solution Approach 1:
The patent substitutes computational validation with physical printing validation. By embedding number strings in printed images and requiring physical printing operations for proof-of-work, the system replaces energy-intensive computational processes with physical manufacturing processes that have lower energy consumption and consequently lower CO2 emissions, while maintaining blockchain validation integrity.
