# Privacy Overview

With this knowledge of [ZK proofs and zk-SNARKs](broken://pages/60TbeRfi0fN9MgKDyMcF), we can see how Bit Bank maintains privacy for its Shielded Assets. Users can prove they have the right to spend funds without needing to reveal what those assets are and how much they have of it. Relayers and private pools then obscure the senders and recipients of transactions such that no identifiable information is compromised at any stage in the process.

To use an old-world analogy, Bit Bank users are writers of letters, ZK proofs fact check the contents of the letters, Bit Bank smart contracts are a sealed envelope, and Relayers are mailmen. All an outside observer can see is that a letter has been posted, but they would have no visibility as to what is in the letter or who has sent it.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.bit-bank.io/privacy-protection/zero-knowledge-proof/privacy-overview.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
