Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain systems use decentralized and anonymous operation, then security and transparency are improved, but scalability and enterprise control capability deteriorate
Solution Approach 1:
The system segments blockchain operations into two parts: public key operations remain decentralized on the blockchain, while private key operations are segmented and performed locally on enterprise premises through on-premises nodes. This segmentation allows enterprises to maintain control over sensitive cryptographic operations while preserving blockchain security for public verification.
Solution Approach 2:
An on-premises node acts as an intermediary between the enterprise and the blockchain network. This intermediary performs cryptographic operations locally and only communicates necessary data to the blockchain, enabling enterprises to maintain control while participating in the decentralized blockchain ecosystem.
2Reliability
If blockchain systems maintain decentralization, then security is improved, but operation verification efficiency and scalability deteriorate
Solution Approach 1:
The on-premises node performs preliminary cryptographic verification of operation payloads before broadcasting them to the blockchain. This preliminary action ensures that only valid operations are submitted to the network, improving verification efficiency while maintaining security standards.
Solution Approach 2:
The on-premises node autonomously performs parameter comparison, validation, and cryptographic signing of operation payloads without requiring centralized verification. This self-service capability improves operational efficiency while maintaining decentralized security.
3Productivity
If blockchain systems process operations centrally, then scalability is improved, but security control and authorization management deteriorate
Solution Approach 1:
The system segments security control functions by keeping private key management and cryptographic operations on enterprise premises while allowing centralized broadcasting of operations to the blockchain. This segmentation enables scalability through centralized processing while maintaining security control through distributed key management.
Solution Approach 2:
The on-premises node serves as an intermediary that maintains security control locally while enabling scalable operation processing through the blockchain network. It verifies operations locally and broadcasts them centrally, combining both security and scalability benefits.
4Reliability
If blockchain systems use complex authorization policies, then security is improved, but operation complexity and processing time deteriorate
Solution Approach 1:
The on-premises node acts as an intermediary that handles complex authorization logic locally before operations are submitted to the blockchain. By processing authorization policies on-premises, the system maintains strong security controls while keeping blockchain operations simple and efficient.
Solution Approach 2:
Complex authorization and verification logic is extracted from the blockchain system and placed on the on-premises node. This extraction reduces operation complexity on the blockchain while maintaining security through local policy enforcement.
Data Source
AI summary
A system may include a remote server and an on-premises node. The server may receive a first set of parameters defining a blockchain operation. The server may generate an operation payload based on the parameters. The on-premises node may receive the operation payload from the computing server and decode the operation payload to extract a second set of parameters reflected in the operation payload. The on-premises node may compare the second set of parameters to the first set of parameters to determine whether the second set matches the first set. If the parameters match, the on-premises node may sign cryptographically the operation payload and transmit the operation payload to the computing server for the computing server to broadcast the operation payload to a blockchain to carry out the blockchain operation.
