Multilayered Blockchain Network for Secure Event Consent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In blockchain networks, there is a lack of control over data accessibility, as transaction details are often visible to all nodes, compromising security and privacy.
Innovation Solution
A multilayered blockchain network architecture that utilizes smart contracts on both a source and secondary blockchain network to manage and consent on events, allowing only intended nodes to access and approve transactions, keeping decision-making processes confidential within the secondary network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is made accessible to all nodes in the blockchain network, then transparency and trust are improved, but security and privacy are compromised
Solution Approach 1:
The blockchain network is segmented into multiple layers: a public source blockchain network for transparency and a private secondary blockchain network for security. Different types of nodes (source nodes, secondary nodes, intermediary nodes) are segmented into different layers based on their access requirements, allowing data to be transparently visible to source nodes while remaining secure within the secondary network
2Device complexity
If a single blockchain network is used, then simplicity is maintained, but control over data accessibility is lost
Solution Approach 1:
The system transitions from a single-flat blockchain network to a multilayered architecture with vertical dimensionality. The source blockchain network and secondary blockchain network operate at different layers, with controlled inter-layer communication through intermediary nodes, enabling fine-grained access control while maintaining blockchain simplicity at each layer
3Reliability
If all nodes participate in every transaction, then network consensus is improved, but processing efficiency decreases
Solution Approach 1:
Different nodes have different qualities and roles assigned locally: source nodes initiate transactions and require full transparency, secondary nodes provide security and validation without needing full data access, and intermediary nodes facilitate communication. Each node participates in consensus at its appropriate level, improving overall processing efficiency while maintaining reliability

AI summary
A method for performing an event in a multi-layered blockchain network includes sending a request for an event, from a source to a secondary blockchain network including a plurality of nodes, using a first smart contract stored on the source blockchain network. The method includes receiving the request and updating details of the request in each node using a second smart contract stored on the secondary blockchain network. The method includes identifying by the second smart contract, node(s) that are associated with the event, based on the received request. The method includes receiving consent information from each node of the identified node(s), by the second smart contract, sending a response to the source blockchain network based on the received consent information from each node of the identified node(s), by the second smart contract. The method includes performing the event on the source blockchain network based on the response.
