Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current consortium blockchain admission management methods based on traditional Certification Authority (CA) certificates are complex and prone to security risks, especially with multi-level expansion, failing to adapt effectively to hierarchical management needs.
Innovation Solution
A consortium blockchain admission management method and apparatus that employs a multi-level, outside-in control strategy, using institutional contracts to manage access control through escrow transactions and mode switching, allowing for hierarchical expansion and decentralized power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional CA certificate-based admission management is used, then access control can be implemented, but the system complexity and security risks increase with multi-level expansion
Solution Approach 1:
The patent segments the admission management system into hierarchical levels (first-level nodes directly managing basic admission management components, second-level nodes managing institutional contracts, etc.). This segmentation allows complex multi-level management to be broken down into manageable units, reducing overall system complexity while maintaining security through distributed control at each level.
Solution Approach 2:
The patent introduces a hierarchical dimension to the admission management system, organizing nodes and contracts across multiple levels rather than a flat structure. This dimensional organization allows the system to scale securely by adding levels without proportionally increasing complexity, as each level operates with defined permissions and responsibilities.
2Adaptability or versatility
If multi-level expansion management is implemented, then hierarchical admission management capability is improved, but operation complexity and security risks increase
Solution Approach 1:
The patent divides admission management operations into level-specific tasks. First-level nodes handle basic component admission, second-level nodes handle institutional contract admission, and each level operates independently within its scope. This segmentation makes operations simpler by limiting the scope of management at each level rather than requiring global oversight.
Solution Approach 2:
The patent introduces institutional contracts as intermediary entities between nodes at different levels. These contracts mediate admission requests and enforce access control policies, simplifying operations by providing a standardized interface that nodes interact with rather than requiring direct peer-to-peer management across all levels.
3Adaptability or versatility
If traditional CA certificate system is used, then access control is provided, but the system becomes less adaptable to organizational scale expansion
Solution Approach 1:
The patent implements a nested hierarchical structure where first-level nodes contain basic admission management components, second-level nodes contain institutional contracts that manage first-level nodes, and higher levels contain lower levels. This nesting allows the system to scale adaptively by adding nested levels without fundamentally changing the management approach at each level, maintaining consistency while accommodating growth.

AI summary
Provided in the embodiments of the present application are a consortium blockchain admission management method and apparatus, which are applied to the technical field of blockchains. The method comprises: for each first-level node which has a direct access control permission for a basic admission management component, in response to a hosting transaction, which is initiated by the first-level node toward the basic admission management component, the basic admission management component constructing a corresponding second-level institution contract; and when the second-level institution contract is in a cooperation mode, in response to a node admission transaction, which is initiated by an initial second-level node toward the second-level institution contract, adjusting second-level nodes, wherein each second-level node has an indirect access control permission for the basic admission management component and can join a blockchain network, and the second-level institution contract realizes multi-level node admission management by means of multi-level expansion. In the present application, admission management is performed on nodes of a blockchain network by means of multi-level control, such that the nodes can be adapted to a level-based admission management requirement during expansion of the institution scale and the blockchain node scale, and thus, the robustness of a node admission management mechanism is better, and the security thereof is higher.
