Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If centralized servers are used for data storage, then data access and management are simplified, but the system becomes vulnerable to hacking and centralized points of failure
Solution Approach 1:
The patent segments the centralized data storage system into a decentralized blockchain network where data is distributed across multiple nodes. Each node stores a copy of the ledger, eliminating the single point of failure. The segmentation of data into blocks with cryptographic hashes ensures that no single entity controls the entire system, thereby reducing vulnerability to hacking while maintaining data accessibility through the distributed network.
Solution Approach 2:
The patent introduces cryptographic hash functions and digital signatures as intermediaries between data storage and verification. These cryptographic mechanisms act as mediators that enable trustless verification of data integrity without requiring a centralized authority. The hash functions create immutable links between blocks, while digital signatures provide authentication, allowing the system to maintain reliability without centralized control.
2Ease of operation
If locally saved files are used for data storage, then data accessibility is improved, but the files can be hacked, lost, or destroyed
Solution Approach 1:
The patent merges local data storage with a distributed blockchain network. Users can access their data locally while simultaneously maintaining a verified copy on the decentralized blockchain. This combination allows users to benefit from local accessibility while the blockchain provides redundancy and protection against loss or destruction. The cryptographic linking of local data to blockchain records ensures integrity without sacrificing accessibility.
3Reliability
If electronic notarization and digital signatures are used for verification, then data integrity is certified, but the system still relies on centralized authorities
Solution Approach 1:
The patent implements self-service verification through cryptographic hash functions that automatically verify data integrity without requiring centralized notarization. The blockchain network itself performs the verification function through its distributed consensus mechanism. Each node can independently verify data integrity by checking cryptographic hashes, eliminating the need for external centralized authorities while maintaining robust verification capabilities.
4Reliability
If a decentralized blockchain system is implemented, then vulnerability to hacking is reduced, but system complexity increases
Solution Approach 1:
The patent uses cryptographic copying through hash functions that create immutable representations of data blocks. Each block contains a hash of the previous block, creating a chain of cryptographic copies that verify integrity without requiring complex centralized management. This copying mechanism provides security through mathematical verification rather than complex architectural controls, reducing the effective complexity while maintaining high reliability.
