Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current centralized information systems are expensive to maintain, inefficient, and vulnerable to cyber-attacks, while decentralized ledger systems require large bandwidth and computational resources, and existing blockchain implementations are not suitable for environments with limited resources and real-time information exchange needs.
Innovation Solution
The FREE system implements a distributed ledger system with a hybrid network overlay that uses a permissioned blockchain architecture, incorporating quality of service techniques and link sensing mechanisms to optimize data flow and security, allowing for efficient and secure data transmission in bandwidth-limited environments by designating super nodes for block validation and using a consensus algorithm to ensure data integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a decentralized ledger system is implemented, then security and data integrity are improved, but bandwidth consumption and computational resources increase significantly
Solution Approach 1:
The patent segments the network into overlay nodes and underlay nodes, where only overlay nodes participate in blockchain validation. This segmentation reduces the number of nodes performing computationally intensive operations, thereby lowering overall computational resource consumption while maintaining data integrity through the distributed ledger.
Solution Approach 2:
The patent introduces overlay nodes as intermediaries between underlay nodes and the blockchain network. Overlay nodes aggregate transactions from multiple underlay nodes and submit them to the blockchain, reducing the computational burden on individual nodes and optimizing bandwidth usage while preserving the decentralized security model.
2Reliability
If a decentralized ledger system is implemented, then security and data integrity are improved, but network bandwidth capacity requirements increase
Solution Approach 1:
The network is segmented into overlay and underlay layers, where overlay nodes handle blockchain communication and underlay nodes handle local transactions. This segmentation reduces redundant data transmission across the entire network, optimizing bandwidth utilization while maintaining security through the distributed ledger architecture.
Solution Approach 2:
Multiple underlay nodes are combined into a single overlay node that aggregates their transactions before submitting to the blockchain. This merging reduces the total number of transactions propagated across the network, thereby reducing bandwidth consumption while maintaining the security benefits of decentralization.
3Stability of the object's composition
If traditional blockchain architecture is used, then data immutability is ensured, but real-time information exchange becomes inefficient
Solution Approach 1:
The patent segments the system into a fast underlay network for real-time local transactions and a slower overlay network for blockchain immutability. This allows underlay nodes to exchange information efficiently in real-time while the overlay nodes periodically anchor these transactions to the immutable blockchain, achieving both real-time efficiency and data immutability.
Solution Approach 2:
The patent creates a copy of the transaction processing function in the underlay layer that operates independently and rapidly, while the overlay layer maintains the immutable copy on the blockchain. This copying allows real-time information exchange without compromising the immutability guarantee of the blockchain.
4Ease of manufacture
If centralized architecture is used, then system cost is reduced, but vulnerability to cyber-attacks increases
Solution Approach 1:
The patent segments the network into centralized underlay nodes for local processing and decentralized overlay nodes for security-critical functions. This segmentation allows the system to maintain low operational costs through efficient local processing while achieving cyber-attack resistance through the decentralized blockchain validation layer.
Solution Approach 2:
Different parts of the system have different security requirements. The patent applies local quality by making underlay nodes (local transactions) less expensive and overlay nodes (blockchain validation) more secure. This allows cost-effective operation for routine transactions while maintaining high security for critical data integrity functions.
