Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If blockchain nodes are migrated to cloud services, then infrastructure scalability is improved, but deployment and maintenance costs increase
Solution Approach 1:
The system segments blockchain functionality into a lightweight client application and a cryptographic acceleration card, allowing the core blockchain logic to run locally on personal devices rather than requiring centralized cloud infrastructure. This segmentation enables scalable participation while reducing per-node infrastructure costs.
Solution Approach 2:
The cryptographic acceleration card provides self-contained key management and cryptographic operations, enabling nodes to perform security-critical functions independently without relying on external cloud services. This self-service capability reduces ongoing maintenance costs and infrastructure dependence.
2Ease of operation
If cloud infrastructure is used for blockchain nodes, then deployment flexibility is improved, but technical interface consistency deteriorates
Solution Approach 1:
The cryptographic acceleration card implements a universal interface standard that works across different blockchain implementations and cloud environments. This multi-functional design ensures technical interface consistency while maintaining deployment flexibility across various platforms and configurations.
3Device complexity
If cryptographic operations are performed using standard CPU, then device complexity is reduced, but processing efficiency deteriorates
Solution Approach 1:
The cryptographic acceleration card serves as an intermediary device between the CPU and the cryptographic operations. It offloads intensive cryptographic computations from the general-purpose CPU to specialized hardware, significantly improving processing efficiency while keeping the overall system architecture simple and compatible with standard computers.
