Solution Overview

Problem

Existing blockchain networks face challenges in ensuring confidentiality and performance due to the transmission of private data through unauthorized nodes, which can lead to data compromise and network bandwidth issues.

Innovation Solution

Implementing a structured network topology with defined network zones and topology identification numbers to restrict the movement of confidential data, ensuring it is only transmitted between authorized nodes within the same network zone.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If private data is transmitted through existing networking infrastructure using gossip protocol, then data can be shared among nodes, but unauthorized nodes can potentially access and compromise the sensitive data

Engineering Contradiction:

ImproveconfidentialityVSAvoiddata compromise risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The network is segmented into virtual network zones based on topology identification numbers, where each zone represents a confidentiality group. Nodes are assigned to specific zones, and data transmission is restricted within these segments, preventing unauthorized nodes from accessing sensitive data even if they are part of the overall network infrastructure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A structured network topology with virtual zones acts as an intermediary layer between nodes, controlling and mediating data transmission paths. This intermediary structure ensures that data packets are routed only through authorized nodes within the same confidentiality group, blocking direct access by unauthorized nodes.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If private data is transmitted to all nodes in the network, then every node can receive the data, but network bandwidth is consumed by redundant transmissions to unauthorized nodes

Engineering Contradiction:

Improvedata exchange efficiencyVSAvoidnetwork bandwidth consumption

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The network transmission has different quality requirements for different nodes based on their authorization status. Authorized nodes within the same confidentiality group receive full data transmissions, while unauthorized nodes are excluded from receiving transmissions. This local differentiation optimizes bandwidth usage by directing data only where it is needed and permitted.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The network is divided into virtual zones that segment data transmission paths. Data is transmitted only within these segmented zones rather than across the entire network, reducing redundant transmissions to nodes outside the confidentiality group and improving overall data exchange efficiency.

Inventive Principle:

Principle #1Segmentation

AI summary

A system (100) and a method (200) for exchanging private data among nodes (102a, 102b, . . . , 102n) in a blockchain network (102). The method (200) comprises defining one or more groups of nodes; implementing a structured network topology with one or more network zones for establishing connections between the nodes; assigning a topology identification number to each of the nodes, such that the topology identification numbers of the nodes in each of the network zones are in a series; defining a limit for each of the network zones based on the topology identification numbers of the nodes therein; and exchanging private data between the nodes in the blockchain network in consideration of the defined limits for the corresponding network zones thereof.
