Hierarchical Blockchain Network Asset Transfer Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The scalability of transaction processing in blockchain networks is limited due to all nodes holding copies of transactions, leading to insufficient processing speed and safety concerns in asset transfers between networks, particularly in hub-type topologies where networks have equal reliability, resulting in insecurity during asset transfers.
Innovation Solution
A hierarchical network system is introduced, where upper and lower networks manage transactions and asset transfers differently, with the upper network allowing unlimited asset transfers to lower networks and the lower network transferring assets to the upper network only if the total amount sent does not exceed the amount received, ensuring asset transfers are safer by regulating the total amount of assets transferred.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all nodes on a P2P network hold a copy of expanded transactions, then the reliability of transaction verification is improved, but the scalability of transaction processing deteriorates
Solution Approach 1:
The patent divides the single P2P network into multiple hierarchical networks with different levels. Each network maintains its own transaction copy set, segmenting the verification burden. Upper-level networks verify cross-network transactions while lower-level networks verify local transactions, enabling scalable processing without sacrificing verification reliability.
Solution Approach 2:
The patent introduces a hierarchical dimension to the network structure, transitioning from a flat P2P topology to a multi-level architecture. This dimensional change allows transactions to be processed at appropriate levels, with upper networks handling inter-network verification and lower networks handling intra-network verification, thus improving scalability while maintaining reliability.
2Productivity
If a hub type topology is used to divide networks, then the scalability of transaction processing is improved, but the safety of asset transfer deteriorates due to equal reliability among networks
Solution Approach 1:
The patent implements an asymmetric hierarchical structure where upper-level networks are assigned higher reliability and authority than lower-level networks. This asymmetry is reflected in the asset transfer mechanism: lower networks can transfer assets to upper networks without strict limits, but upper networks can only transfer to lower networks if the receiving network has sufficient asset reserves, creating differentiated safety mechanisms appropriate to each level.
Solution Approach 2:
The patent applies different reliability standards and transfer rules to different levels of the hierarchical network. Upper-level networks enforce stricter verification and have different transfer constraints compared to lower-level networks. This local quality differentiation ensures that asset transfer safety is adapted to the specific characteristics and authority level of each network.
3Ease of operation
If asset transfer is allowed between equal networks without restrictions, then the ease of operation is improved, but the reliability of asset transfer deteriorates
Solution Approach 1:
The patent introduces upper-level networks as intermediary authorities that mediate asset transfers between lower-level networks. When assets are transferred across networks, the hierarchical structure provides an implicit verification layer that ensures safety without requiring complex peer-to-peer negotiation, thus maintaining ease of operation while improving reliability.

AI summary
The present invention ensures safety in the movement of assets between networks. Movement of assets from a higher-level network A to a lower-level network B is allowed without restriction, and movement of assets from the lower-level network B to the higher-level network A is allowed subject to the condition that the total quantity ∑ba of assets delivered to the higher-level network A does not exceed the total quantity ∑ab of assets received from the higher-level network A.
