Engineering Contradiction Analysis
1Reliability
If proof of work consensus is used to achieve distributed system consensus, then security and decentralization are improved, but energy consumption increases significantly
Solution Approach 1:
The patent replaces the traditional cryptographic hash computation mechanism with a physical measurement-based verification system. Instead of requiring nodes to perform intensive cryptographic operations to prove work, the system uses physical sensors to measure and verify properties of the blockchain data structure, substituting computational mechanics with physical measurement to reduce energy consumption while maintaining consensus security
Solution Approach 2:
The patent changes the fundamental parameter being verified from computational output (hash values) to physical measurement data (temperature, pressure, or other physical properties). This parameter transformation allows the system to maintain the proof-of-work security model while eliminating the need for energy-intensive cryptographic computations, directly addressing the energy consumption problem
2Reliability
If proof of work consensus is used to ensure network security, then transaction validation reliability is improved, but transaction throughput decreases
Solution Approach 1:
The patent replaces the sequential cryptographic verification process with parallel physical measurement verification. Multiple transactions can be validated simultaneously by measuring physical properties, eliminating the bottleneck caused by sequential hash computations and thereby increasing transaction throughput while maintaining validation reliability
Solution Approach 2:
The patent performs physical measurements and validations in advance during the block creation process, before transactions are submitted for processing. This preliminary action allows the system to pre-verify the validity of transactions based on physical state, reducing the computational burden during transaction processing and improving overall throughput
3Reliability
If cryptographic operations are performed for each transaction to achieve consensus, then security is improved, but computational burden increases
Solution Approach 1:
The patent substitutes complex cryptographic operations with simple physical measurement and comparison operations. Instead of requiring nodes to perform multiple rounds of hashing and verification, the system simply measures physical properties and compares them against expected values, dramatically reducing computational complexity while preserving security through the physical unclonability of the measured states
