Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a third party intermediary is used for API request and response balancing and control, then data transfer validation can be performed, but development time increases and system complexity increases
Solution Approach 1:
The patent extracts the balancing and control functionality from the third party intermediary system and implements it directly within the API gateway. This allows the system to maintain data transfer validation capabilities while eliminating the need for external proprietary systems, thereby reducing development time and complexity.
Solution Approach 2:
The patent introduces an on-chain event mechanism as an intermediary between API requests and responses. This event-driven approach enables validation and balancing functionality to be implemented within the existing API gateway infrastructure without requiring a separate third party system, thus maintaining reliability while reducing development overhead.
2Reliability
If a third party intermediary is used for API request and response balancing and control, then data transfer validation can be performed, but device complexity increases
Solution Approach 1:
The patent removes the need for complex third party intermediary systems by extracting the essential balancing and control functionality and implementing it natively in the API gateway. This simplifies application design by eliminating the need to integrate with external proprietary systems while maintaining validation capabilities.
Solution Approach 2:
The API gateway performs balancing and control operations autonomously using on-chain events and smart contracts. This self-service approach eliminates the need for complex third party integration and manual configuration, thereby reducing application design complexity while maintaining data transfer validation.
3Reliability
If a third party intermediary is used for API request and response balancing and control, then central authority for B&C process is established, but tamper-proofness is compromised
Solution Approach 1:
The patent uses blockchain on-chain events as an intermediary to establish a decentralized authority for balancing and control. This approach maintains the central coordination function while leveraging blockchain's inherent tamper-proof characteristics, thereby eliminating the vulnerability associated with third party intermediaries.
Solution Approach 2:
The patent replaces the mechanical third party intermediary system with a blockchain-based smart contract mechanism. This substitution maintains the central authority function for B&C process while providing cryptographic tamper-proof guarantees, as blockchain data cannot be altered without detection.
4Reliability
If third party proprietary systems are used, then B&C monitoring can be performed, but time to market increases
Solution Approach 1:
The patent extracts B&C monitoring functionality from third party proprietary systems and implements it directly in the API gateway using on-chain events. This eliminates the need for lengthy integration processes with external systems, thereby maintaining monitoring capabilities while significantly reducing time to market.
Solution Approach 2:
The API gateway performs B&C monitoring autonomously through smart contracts and on-chain events without requiring third party systems. This self-service capability eliminates dependency on external proprietary solutions, maintaining monitoring reliability while accelerating time to market by removing integration overhead.

AI summary
A balancing and control (B&C) system for API transactions is disclosed. The system may write a request confirmation and a request acknowledgement to a blockchain in response to an API request being transmitted from a consumer system to a provider system, with the request confirmation and the request acknowledgement each comprising a request hash of the API request. The system may also write a response confirmation and a response acknowledgement to the blockchain in response to an API response being transmitted from the provider system to the consumer system, with the response confirmation and the response acknowledgement each comprising a response hash of the API response. The blockchain may execute a smart contract to compare the request hashes from the request confirmation and the request acknowledgement and the response hashes from the response confirmation and the response acknowledgement to identify one or more out-of-balance events.
