Solution Overview
Problem
Centralized databases face issues such as single points of failure, dependency on network connectivity, high latency, and limited data access, which hinder efficient data management and user preference updates.
Innovation Solution
A blockchain network with multiple nodes that share a ledger, allowing for decentralized data storage, consensus-based validation of user preference updates, and secure, permissioned access to ensure data integrity and redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized database is used, then data management is easy and control is centralized, but the system has a single point of failure and high dependency on network connectivity
Solution Approach 1:
The patent divides the centralized database into multiple distributed nodes, each maintaining a copy of the ledger. This segmentation eliminates the single point of failure while maintaining ease of operation through automated consensus mechanisms that manage data synchronization across nodes.
Solution Approach 2:
The patent creates multiple copies of the data across distributed nodes in the network. Each node maintains a complete or partial copy of the ledger, ensuring data availability and system reliability even when individual nodes fail or network connectivity is interrupted.
2Quantity of substance
If a centralized database is used, then data redundancy is minimized, but data access is limited and latency is high
Solution Approach 1:
The patent segments the data storage function across multiple nodes, allowing parallel data access operations. Different nodes can simultaneously process read and write requests, reducing access latency while maintaining appropriate redundancy through the distributed ledger structure.
3Device complexity
If a centralized database is used, then security control is simplified, but user preference updates cannot be effectively propagated
Solution Approach 1:
The patent implements a feedback mechanism where nodes validate and propagate preference updates through the network using consensus algorithms. This ensures that security control is maintained through verification while enabling efficient propagation of user preference updates across all nodes simultaneously.
4Adaptability or versatility
If multiple devices access a centralized database simultaneously, then collaboration is enabled, but bottlenecks occur and data integrity is at risk
Solution Approach 1:
The patent segments the data access operations across multiple independent nodes, allowing simultaneous read and write operations without central bottlenecks. Each node processes transactions independently while maintaining consistency through the distributed ledger, enabling multi-device access with improved throughput.
Solution Approach 2:
The patent introduces a consensus mechanism as an intermediary that coordinates data integrity across multiple accessing devices. This mediator ensures that simultaneous operations maintain data consistency without creating bottlenecks, as the consensus protocol efficiently validates and propagates changes across the network.
Data Source
AI summary
An example operation may include one or more of receiving, by a first blockchain node of a blockchain network, first sensor updates from one or more sensors associated with the first blockchain node and creating a blockchain transaction to store updated action defaults and validated sensor updates to the shared ledger. The example operation may also include one or more of receiving, by a second blockchain node of the blockchain network, second sensor updates from one or more sensors associated with the second blockchain node, reading the shared ledger to determine updated action defaults and validated sensor updates corresponding to the second sensor updates, and interacting with a device based on the updated action defaults and validated sensor updates. The first blockchain node includes a shared ledger and historical sensor data. The second blockchain node includes the shared ledger.
