# Sovereign Data Control (Proof of Concept)

Users today lack true ownership and control over their personal data, which is often siloed in centralized systems that limit transparency, privacy, and control. Current knowledge management solutions do not fully empower users with sovereignty over their data.

### Solution Overview

The [Data Ownership (SOLID + BSV) proof of concept](https://hub.bsvblockchain.org/demos-and-onboardings/demo-solutions/demos/data-ownership) integrates SOLID pods with BSV blockchain to create a decentralized personal knowledge management system.

SOLID provides personal data vaults with user ownership, while BSV enables public timestamping, notarization, and micropayments.

The demo shows **users maintaining data control while leveraging BSV for proof of existence, governance, and immutable audit trails.**

Built as a "second brain" application using NextJS and W3C standards, it demonstrates pay-per-use storage with micropayments, content sharing capabilities, and seamless AI integration while following decentralized identity management protocols.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://hub.bsvblockchain.org/higher-learning/bsv-academy/introduction-to-blockchain-technology/the-fundamentals-of-blockchain-and-web-3-technology/sovereign-data-control-proof-of-concept.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
