# Roles in the SSI framework

SSI involves three core participants, commonly depicted as the **SSI Triangle**:

* **Issuers:** Trusted entities authorized to issue VCs. This could include universities issuing diplomas, governments providing licenses, or employers verifying employment status, etc.
* **Holders:** Individuals or entities who own their DIDs and VCs stored securely in their digital wallets.
* **Verifiers:** Parties who rely on VCs to confirm an identity claim. This could be an employer verifying work experience for a job application or a bank verifying age for opening an account.

Empeiria’s End-to-End Verifiable Data Infrastructure (EVDI) offers tools for all three key participants of the SSI Triangle:

**Issuer:** Empeiria's integration tools let issuers add credential issuance to their existing data infrastructure with minimal changes.

**Holder:** Empeiria places Holders in control of their data. Empe Wallet is a convenient and secure place to store verifiable credentials, which can be shared privately and securely with Verifiers.

**Verifier:** Using Empeiria’s easily deployable tool, verifiers can quickly check the validity of verifiable credentials, without accessing sensitive information or contacting the issuer. This makes verifying information easier and builds trust between verifiers and holders.

In short, EVDI gives all three participants the tools they need: issuance for Issuers, secure storage and sharing for Holders, and fast validity checks for Verifiers.

## 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.empe.io/understand/self-sovereign-identity/roles-in-the-ssi-framework.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.
