# Overview

The OCC Framework architecture was designed to be as lightweight and modular as possible while retaining core decentralization primitives. No personal data whatsoever is collected, while the only party with access to communication data is the user himself. Code is law principle applies! Connected by the OCC SDK, four main legos complete the on-chain communication framework:

1. the OCC Protocol,
2. blockchain network,
3. encryption,
4. decentralized storage.
