# Architecture by Layers

### Let's Start

Architecture refers to the components and subcomponents or layers that comprise a complete Immu3 stack. Each layer has a unique role, from the underlying blockchain layer, storing data to enabling communication encryption and ensuring user connectivity and integration across the system. Understanding these layers is crucial for developers (i.e., integrators) and start-up entrepreneurs seeking to leverage Immu3s blockchain communication technology effectively.

### Layers

Connected by the [OCC SDK](https://wiki.immu3.io/integrators/occ-sdk) (i.e. software development kit) and later the Integrator Dashboard, seven layers complete the on-chain communication framework:

* [Integrator use cases](/integrators/use-cases-and-integrations.md)
* [AppSuite](https://wiki.immu3.io/end-users/appsuite)
* [White labels](/integrators/occ-white-labels.md)
* [Encryption](/integrators/architecture-by-layers/encryption.md)
* [OCC Protocol](/integrators/architecture-by-layers/occ-protocol-v.1.md)
* [Decentralized storage](/integrators/architecture-by-layers/pollinationx-decentralized-storage-infra.md)
* [Blockchain network](/integrators/multi-chain.md)

# Agent Instructions: 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:

```
GET https://wiki.immu3.io/integrators/architecture-by-layers.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
