Innovation Solution
A system comprising a receiver apparatus, cryptography module, and unambiguity confirmation module is used to facilitate communication between old devices and new blockchain-based infrastructures by ensuring device readiness and compliance with predefined requirements before data transmission, utilizing cryptographic checks and conversion modules to ensure compatibility and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If old devices are integrated with new blockchain-based infrastructures, then communication capability is improved, but compatibility issues and unexpected problems occur due to complex differences in device characteristics
Solution Approach 1:
A receiver apparatus is introduced as an intermediary component between old devices and the blockchain-based infrastructure. This receiver apparatus includes a conversion module that translates data formats and communication protocols, allowing old devices to interact with the new system without direct compatibility issues. The intermediary handles the complexity of protocol translation and data format conversion, resolving the contradiction between enabling communication and maintaining reliability.
Solution Approach 2:
The system dynamically adjusts communication parameters such as data formats, transmission protocols, and addressing schemes based on the characteristics of connected devices. The receiver apparatus detects device properties and modifies transmission parameters accordingly, enabling compatible communication between heterogeneous systems while maintaining reliable data exchange.
2Reliability
If comprehensive checks are performed to ensure device readiness and compliance, then data integrity and security are improved, but system complexity and processing time increase
Solution Approach 1:
The receiver apparatus performs readiness checks and compliance verification before data transmission begins. Device characteristics are evaluated in advance, and configuration is prepared beforehand. This preliminary action ensures that only compliant devices are allowed to communicate, maintaining data integrity while avoiding the need for continuous complex verification during data exchange operations.
Solution Approach 2:
The system implements feedback mechanisms where the receiver apparatus continuously monitors device compliance and transmission integrity. Based on this feedback, the system can adjust processing requirements dynamically, reducing overall system complexity by only performing comprehensive checks when necessary while maintaining security and integrity standards.
3Reliability
If redundancy measures are implemented to ensure system availability, then reliability is improved, but costs and resource consumption increase
Solution Approach 1:
The receiver apparatus includes self-diagnostic and self-configure capabilities that automatically ensure system availability without requiring redundant backup systems. The device monitors its own operational status and can recover from minor failures independently, reducing the need for expensive redundancy infrastructure while maintaining high availability.

AI summary
A gateway or a network adapter allows legacy devices to be connected to a distributed database system such as a blockchain without having to change any configuration. Unique cryptographic data is associated with the gateway I network adapter. To improve the availability of the coupling, an additional gateway or additional network adapter with identical cryptographic data is provided, wherein never both couplings are simultaneously active for preventing replications or ensuring the uniqueness of the cryptographic data. The availability of the active coupling is monitored using a state synchronization channel. Alternatively, the monitoring can also be effected by a test whether data sent by the legacy devices are successfully stored within a certain period of time or number of data blocks in the blockchain. In the event of an interference of the active coupling, the previously inactive gateway I network adapter assumes the coupling of the legacy devices and the blockchain.
