Blockchain Representative Node IP Address Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In blockchain systems, representative node devices are vulnerable to attacks when their IP addresses are exposed, compromising the security and efficiency of the network.
Innovation Solution
A method and apparatus for electing a representative node device in a blockchain system, where a target server receives and manages IP address information, transmitting the list only to elected representative nodes, thereby reducing exposure and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If representative node devices use direct communication to transfer transaction data using IP addresses, then communication efficiency is improved, but security deteriorates due to IP address exposure and vulnerability to attacks
Solution Approach 1:
The patent introduces a target server as an intermediary between representative node devices. This server manages and distributes IP address information selectively, allowing direct communication among representative nodes while preventing other nodes from obtaining these addresses. The intermediary protects the system by controlling information flow and isolating sensitive data from unauthorized access.
2Ease of operation
If IP address information of representative node devices is broadcast to all nodes, then network connectivity is established, but security deteriorates due to widespread exposure and attack risk
Solution Approach 1:
The patent implements local quality by differentiating information access rights among nodes. Representative node devices receive and can use IP address information for direct communication, while non-representative nodes do not receive this information. This selective distribution ensures that sensitive information is localized to only those nodes that require it for their function, reducing overall exposure risk.

AI summary
A method for electing a representative node device for a blockchain system includes: receiving IP address information of a first node device, the first node device being in a candidate state for a representative node device; receiving, from the first node device, an IP address obtaining request for requesting IP address information of a representative node device; when the first node device is determined to be a representative node device of the blockchain system elected in a current election process, transmitting, to the first node device, an IP address list comprising IP address information of representative node devices elected in the current election process; and when the first node device is determined not to be a representative node device of the blockchain system elected in the current election process, skipping the IP address obtaining request.
