Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blockchain-based content distribution systems lack privacy for participants and incur inefficient transaction costs due to gas fees on public chains.
Innovation Solution
A hierarchical blockchain network structure with multiple levels of interconnected blockchains, including a master chain and user/content provider chains, ensuring privacy and minimizing transaction costs through a nested arrangement that optimizes scalability and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If public block chains are used to verify ownership of content, then transparency and verification are improved, but privacy of participants deteriorates
Solution Approach 1:
The system segments the blockchain network into public and private components. Ownership verification is performed on public chains for transparency, while participant identities and sensitive content metadata are stored on private chains, segregating information by sensitivity level to maintain both verification accuracy and privacy
Solution Approach 2:
The patent introduces private chains as intermediary layers between users and public verification systems. These private chains act as mediators that enable ownership verification through cryptographic proofs without exposing participant identities or sensitive content information to the public network
2Reliability
If minting new blocks on large public chains is used for content distribution, then ownership verification is improved, but transaction efficiency deteriorates
Solution Approach 1:
The system divides blockchain operations into two segments: critical ownership verification transactions are processed on public chains for reliability, while routine content distribution and metadata transactions are handled on private chains, improving overall transaction throughput by offloading non-critical operations
Solution Approach 2:
The patent adds a vertical dimension to the blockchain architecture by implementing a hierarchical structure with multiple chain levels. This multi-dimensional approach allows transactions to be routed to appropriate chain levels based on their criticality, with private chains handling high-volume operations and public chains providing periodic verification
3Reliability
If minting new blocks on large public chains is used for content distribution, then ownership verification is improved, but transaction costs increase
Solution Approach 1:
The system segments transaction types by cost sensitivity, routing expensive verification-critical transactions to public chains while moving low-cost routine operations to private chains, optimizing the overall cost structure by matching transaction types with appropriate chain environments
Solution Approach 2:
The patent implements a copy-verification mechanism where content metadata and ownership proofs are replicated across chain levels. Private chains maintain copies of ownership data for efficient local verification, eliminating the need to repeatedly perform expensive public chain verification operations

AI summary
A method, apparatus, and computer-readable medium for executing operations on a hierarchical block chain network, including generating the hierarchical block chain network including a master block chain linked to a machine block chain, a content provider block chain, and a user block chain, receiving a plurality of requests to perform a plurality of operations on the hierarchical block chain network, the plurality of operations including executing a transfer from a user corresponding to the user sub-chain to a content provider corresponding to a content provider sub-chain that is linked to the content block and linking a user sub-chain in the one or more user sub-chains to a content block in the content block chain by updating the corresponding content block to reference the user sub-chain, and executing the plurality of operations based at least in part on detection of authorization from a majority of the three or more superusers.
