# zkIdentity System

#### **Overview**

zkIdentity is zkShine’s **privacy-preserving identity layer**, allowing users to verify attributes not identities.

Instead of exposing KYC data, zkIdentity creates **cryptographic attestations** that can be verified on-chain without revealing the underlying data.

#### **Core Principles**

| Concept                        | Description                                                                           |
| ------------------------------ | ------------------------------------------------------------------------------------- |
| **Selective Disclosure**       | Users reveal only the facts they choose (e.g., “I’m over 18”) — not full credentials. |
| **Self-Custody**               | Identity proofs are owned, generated, and stored by users inside zkVault.             |
| **Interoperable Attestations** | zkIdentity credentials can be recognized by any dApp supporting zkShine SDK.          |
| **ZK-Based Validation**        | Smart contracts verify authenticity without accessing raw identity data.              |

## 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.zkshine.xyz/privacy-framework/zkidentity-system.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.
