Blockchain Node Segmentation for Transaction Speed and Decentralization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Permissionless blockchain systems face challenges with low transaction processing speed and lack of decentralization, as they rely on a central management system and do not have an entity responsible for operation or management.
Innovation Solution
A blockchain system with an open membership operation and a confirmation group structure, where node participation is free, and an entity manages the system, using confirmation nodes, management nodes, and operator nodes to configure and distribute blockchain blocks while ensuring decentralization and transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a permissionless blockchain system is used with decentralized node participation, then system transparency and trustlessness are improved, but transaction processing speed deteriorates
Solution Approach 1:
The system segments nodes into different types (operator nodes, management nodes, confirmation nodes) with distinct functions. Operator nodes manage the system, management nodes generate blocks, and confirmation nodes validate transactions. This segmentation allows parallel processing where multiple confirmation nodes can validate transactions simultaneously while fewer management nodes handle block generation, thereby improving transaction processing speed while maintaining transparency through the distributed confirmation node network.
2Productivity
If a permissioned blockchain system is used with restricted node participation, then transaction processing speed is improved, but decentralization deteriorates
Solution Approach 1:
The system applies local quality by giving different roles and permissions to different node types. Confirmation nodes have the local capability to independently validate transactions and participate in consensus, while management nodes have specialized functions for block generation. This distributed capability across node types enables faster processing through role specialization while maintaining decentralization because confirmation nodes remain distributed and can independently verify transactions without central control.
3Adaptability or versatility
If open node participation is allowed, then system accessibility and decentralization are improved, but system management and control deteriorate
Solution Approach 1:
The system introduces operator nodes as intermediaries between the central managing entity and the distributed confirmation nodes. Operator nodes receive instructions from the managing entity and distribute them to confirmation nodes, while also collecting status information and reporting back. This intermediary layer enables open participation by allowing any node to join as a confirmation node while maintaining manageable control through the operator node hierarchy that implements centralized policies in a distributed manner.
4Reliability
If consensus is achieved among many nodes, then system reliability and security are improved, but transaction processing time increases
Solution Approach 1:
The system applies partial action by requiring consensus only from a subset of confirmation nodes rather than all nodes in the network. Management nodes generate blocks and a predetermined number of confirmation nodes validate them, which is sufficient to ensure security without requiring every node to participate in every consensus round. This partial consensus approach reduces the time required for transaction processing while maintaining adequate security through the distributed validation of multiple confirmation nodes.
