SOLID, blockchain and IPFS integration technology

The main introduction is to the system, method and device, as well as their specific application in the cloud computing environment. The following are the key points of the document:

Technical background and objectives:

Limitations of existing technologies: Traditional distributed ledger technology (DLT) and blockchain platforms have limitations in data storage and management, such as data fixity, lack of metadata support, and low data retrieval efficiency.

Objective: Propose an improved blockchain platform that combines SOLID and IPFS technologies to improve data privacy protection, storage and retrieval efficiency.

System and architecture:

Architecture overview: The system includes components such as host organization, blockchain service interface, database system, query interface, authenticator, etc., supporting multi-tenant and distributed ledger network.

Blockchain service: Through the blockchain service interface, the host organization can operate the blockchain and provide blockchain services to tenants and customer organizations.

Metadata definition and management: The blockchain metadata definition manager allows users to define and create metadata and push it to the blockchain to ensure that data is stored in a standardized manner.

Data privacy protection:

Data privacy configuration: Users configure data privacy profiles through a graphical user interface (GUI), specify multiple network-accessible accounts, and retrieve user data from these accounts.

SOLID compliance label: Generate a unique SOLID compliance label for each user, associate it with the data privacy profile, and record it on the public blockchain.

Access control: Implement fine-grained access control through blockchain to ensure that the private data part of the user is inaccessible to the requester.

Data storage and retrieval:

Dynamic metadata verification: Support dynamic metadata verification of data stored on the blockchain to ensure data integrity and consistency.

Index and query: Build blockchain data indexes, support SQL query and filtering mechanisms, and improve data retrieval efficiency.

Incremental update: Store data updates through indexes to avoid rewriting the entire record and reduce the amount of data storage on the blockchain.

Smart contracts and applications:

Smart contract creation: Use blockchain to implement smart contracts, verify transactions, and ensure the effectiveness and security of data updates.

Application deployment: Host organizations can deploy applications on the blockchain to provide customized services to tenants and customers.

GUI Automation: The executable installation package automatically retrieves metadata from the blockchain and generates an application-specific GUI.

Community Sidechain and Consensus Management:

Community Sidechain: Implement user-specific community sidechains and support access permission configuration based on SOLID tags.

Consensus Management: Implement consensus management through the blockchain consensus manager to ensure data consistency and security among network nodes.

User Experience and Operation Process:

GUI Interface: Provides a user-friendly GUI interface for configuring data privacy profiles, defining metadata, viewing blockchain transactions, etc.

Operation Process: Describes in detail the entire operation process of users from creating data privacy profiles to data retrieval.

Description By introducing SOLID, blockchain, and IPFS technologies, an innovative solution is proposed to improve the level of data privacy protection, optimize data storage and retrieval efficiency, and provide users with more secure and convenient data management services.
