Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data exchange mechanisms are implemented between blockchain networks, then data exchange capability is improved, but security risks increase due to lack of central authority
Solution Approach 1:
The patent introduces an intermediary layer consisting of bridge contracts deployed on each blockchain network. These bridge contracts act as mediators that facilitate secure data exchange between networks without requiring direct trust between nodes. The bridge contracts handle authentication, data validation, and secure transmission, thereby enabling data exchange capability while maintaining security through decentralized intermediary components rather than direct peer-to-peer connections.
Solution Approach 2:
The data exchange system is segmented into distinct functional components: bridge contracts on each network, authentication mechanisms, data validation layers, and transmission protocols. This segmentation allows each component to be optimized independently for its specific function while collectively providing both exchange capability and security. The segmentation also enables modular deployment and reduces the complexity of implementing secure cross-chain communication.
2Reliability
If encryption and validation mechanisms are added to secure data exchange, then data security is improved, but processing complexity increases
Solution Approach 1:
The bridge contracts are designed as multi-functional components that simultaneously perform multiple operations: authentication of communicating nodes, validation of data formats and types, encryption of data payloads, and coordination of the exchange process. By consolidating these functions into universal bridge contract components rather than separate specialized modules, the system achieves high data security through comprehensive security measures while managing processing complexity through integrated design.
3Reliability
If multiple encryption layers and validation steps are implemented, then data security is improved, but network bandwidth and processing resources are consumed
Solution Approach 1:
The system performs preliminary actions by establishing secure channels and validating data formats before the actual data exchange occurs. Authentication and data validation are performed in advance through bridge contracts, so that when data transfer happens, the infrastructure is already prepared and optimized for efficient transmission. This preliminary preparation reduces the need for repeated validation and re-encryption during the exchange process, thereby minimizing bandwidth consumption and processing resource usage while maintaining high data security.

AI summary
A request is transmitted to a second computing node of a second blockchain network to perform a data interaction between a first computing node of a first blockchain network and the second computing node. Upon receiving an acknowledgement of the request, a first smart contract, an encrypted first network address and a first authentication code is generated. The first smart contract is encrypted using the first authentication code to generate an encrypted first smart contract. The encrypted first smart contract, the encrypted first network address and the first authentication code is transmitted to the second computing node. A digital signature is received indicating an approval of the first smart contract. Thereafter, data objects are transmitted to the second computing node as agreed in the first smart contract.
