Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional centralized database systems for user information management are limited by their synchronous transaction processing and single-entity control, which restricts data sharing and usage, and are vulnerable to hacking attacks.
Innovation Solution
A blockchain-based network that uses decentralized, replicated databases for user information management, allowing peer-to-peer transactions and enhanced security through cryptographic validation and distributed ledger technology, enabling users to control their own data and validate identities and transactions across the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a centralized database system is used for user information management, then data storage and access control are simplified, but security against hacking attacks deteriorates and data sharing is restricted
Solution Approach 1:
The centralized database is segmented into distributed blockchain nodes across multiple computing devices. Each node maintains a copy of the ledger, eliminating the single point of failure. Transactions are validated and stored across the network rather than in one centralized location, improving security while maintaining data accessibility.
Solution Approach 2:
Instead of storing user information in a single centralized database, the system creates and maintains multiple copies of the blockchain ledger across different computing nodes. These replicated copies ensure that even if some nodes are compromised, the data remains secure and accessible through the distributed network.
2Device complexity
If a centralized database system is used for user information management, then system control is simplified, but data sharing capability deteriorates
Solution Approach 1:
The blockchain network serves multiple functions simultaneously: it stores user information, enables peer-to-peer transactions, facilitates data sharing across applications, and maintains security. The decentralized architecture allows various applications to access and utilize user data without requiring centralized authorization, enhancing versatility while maintaining unified control through cryptographic protocols.
Solution Approach 2:
The blockchain acts as an intermediary layer between users and centralized databases. It enables data sharing and transactions across multiple applications and entities without requiring direct access to centralized systems. The distributed ledger mediates interactions, allowing secure data exchange while maintaining user control and privacy.
3Stability of the object's composition
If synchronous transaction processing is used in centralized databases, then data consistency is maintained, but transaction throughput and processing speed deteriorate
Solution Approach 1:
The system transitions from static synchronous processing to dynamic parallel processing. Multiple transactions can be processed simultaneously across different blockchain nodes in parallel, with the system dynamically coordinating transactions through consensus mechanisms. This dynamic approach maintains data consistency through agreement protocols while significantly improving transaction throughput and processing speed.

AI summary
Systems and methods are described for generating a blockchain-based user profile. In various aspects, one or more blockchain IDs associated with a user is received, where each blockchain ID is associated with a corresponding blockchain. One or more blockchain transactions are identified that are associated with the one or more blockchain IDs, where a trust profile for the user can be generated based on the one or more blockchain transactions. The trust profile can include user information determined from the one or more blockchain transactions.
