Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blockchain consensus technologies face challenges in synchronizing information about nodes that are frequently connected to and disconnected from the network, leading to inconsistencies and potential consensus disruptions.
Innovation Solution
An apparatus and method for synchronizing consensus node information in a blockchain network, which involves receiving committed messages, verifying nodes, broadcasting consensus node information, and using snapshots with hash values to ensure node synchronization, while considering propagation delay and nonce chain generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If nodes are dynamically connected to and disconnected from the blockchain network, then network flexibility and node mobility are improved, but node information synchronization deteriorates leading to consensus inconsistencies
Solution Approach 1:
The system performs preliminary actions by establishing section boundaries in advance and pre-defining synchronization checkpoints at section transitions. When a node joins or leaves the network, the system has already prepared the section structure and synchronization mechanisms, allowing the node to quickly synchronize by retrieving information from the appropriate section start block without disrupting ongoing consensus operations.
Solution Approach 2:
The patent introduces section start blocks as intermediary elements that mediate between dynamic node changes and consensus consistency requirements. These special blocks contain synchronized node information snapshots that act as reference points, allowing dynamically joining or leaving nodes to obtain authoritative node lists without requiring continuous real-time synchronization with all other nodes.
2Reliability
If real-time synchronization of consensus node information is implemented, then consensus consistency is improved, but network overhead and communication costs increase
Solution Approach 1:
The blockchain is divided into sections with designated section start blocks that serve as synchronization checkpoints. Instead of continuously synchronizing node information across all blocks, the system segments the synchronization task to occur only at section boundaries. This reduces network overhead by limiting full node information exchanges to periodic intervals rather than continuous real-time communication.
Solution Approach 2:
The system implements periodic synchronization at section start blocks rather than continuous real-time synchronization. Nodes update their consensus node information periodically when encountering section start blocks, which reduces network traffic and computational overhead compared to maintaining constant synchronization. The periodic interval is determined by the section size, allowing optimization between synchronization freshness and network efficiency.
