Solution Overview

Problem

Conventional blockchain networks face vulnerabilities such as cyberattacks, resource exhaustion, and lack of trust due to their decentralized or centralized architectures, with public networks being vulnerable to cyberattacks and private networks susceptible to sabotage.

Innovation Solution

A federated blockchain network is configured by a processing system that integrates blockchain nodes from multiple CSPs and a public blockchain network, using master-slave agreements, network configurations, and smart contracts to ensure security and trust, with access control and decentralized architecture to mitigate vulnerabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a public blockchain network is used, then any number of users can utilize the network with decentralized architecture, but the network becomes vulnerable to cyberattacks and lacks trust

Engineering Contradiction:

Improveuser accessibilityVSAvoidsecurity against cyberattacks

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the blockchain network into multiple private chains operated by different service providers, each with its own nodes. This segmentation allows the system to maintain decentralized architecture while isolating security risks to specific segments rather than the entire network, thus improving both user accessibility and security reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a consortium of trusted service providers as intermediaries between users and the blockchain network. These intermediaries manage private chains and facilitate transactions, providing a layer of trust and security while maintaining the decentralized nature of the system. The intermediaries verify transactions and coordinate across chains, enhancing both accessibility and security.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a private blockchain network is used, then access is regulated by providing permission to select users, but the network becomes susceptible to sabotage and lacks trust

Engineering Contradiction:

Improveaccess controlVSAvoidvulnerability to sabotage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent divides the private blockchain into multiple independent private chains operated by different service providers. This segmentation prevents sabotage from affecting the entire network, as attacks are isolated to individual chains. Each chain maintains its own access control while the consortium provides overall coordination and trust.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by allowing each service provider to have control over its specific private chain while maintaining different access control policies. This enables tailored security measures for different user groups while the consortium level provides additional trust and coordination, balancing access control with sabotage resistance.

Inventive Principle:

Principle #3Local quality

3Reliability

If blockchain nodes are configured across multiple CSPs, then trust and security are enhanced, but the system complexity increases

Engineering Contradiction:

Improvetrust through decentralized architectureVSAvoidnetwork configuration complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a universal consortium framework that handles multiple functions: coordinating across different private chains, managing trust relationships, facilitating transactions, and providing security. This multi-functional approach consolidates complexity into a single coordinated system rather than requiring separate complex systems for each function, thus enhancing trust while managing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a consortium of intermediaries that simplify the complexity of multi-CSP blockchain configuration. These intermediaries automatically coordinate node configurations, manage trust relationships, and facilitate communication between different service providers, reducing the operational complexity while maintaining enhanced trust and security across the distributed network.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Aspects of the subject disclosure may include, for example, obtaining, from a user device, a master-slave agreement and a first network configuration for a federated blockchain network, transmitting to a cloud service provider (CSP) node the first network configuration, generating first credentials, and transmitting the first credentials to the CSP node. The CSP node configures a first group of blockchain nodes according to the first network configuration and the first credentials. Further embodiments include transmitting the first credentials to a public server that sends it to a public blockchain node and an indication to generate a portion of the federated blockchain network. The public blockchain node configures a second group of blockchain nodes according to a second network configuration based on a public blockchain smart contract. The federated blockchain network comprises the first group of blockchain nodes and the second group of blockchain nodes. Other embodiments are disclosed.
