System Flow

Messa ensures private, decentralized, and intelligent messaging by leveraging the Matrix protocol, local AI processing, and end-to-end encryption. This section describes how data flows through Messa, maintaining privacy and efficiency at every stage.

Step-by-Step Breakdown

1. User Input

The process starts when a user sends a message or interacts with the Messa app. All input is confined to the user's device (Private Zone) and processed locally, without any external data transfer.

2. Encryption at the Source

Messages are encrypted at the device level using end-to-end encryption keys. This ensures that no one—including Messa or home servers—can access the unencrypted content.

3. Matrix Network Handling

The encrypted message is routed through the Matrix protocol:

  • End-to-End Encryption Layer: Ensures the message remains secure during transmission.

  • Encrypted Sync Protocol: Syncs messages securely across devices.

  • Matrix Home Server: Acts as a relay but never decrypts the message.

4. Local Processing on User Device

Once sent, Messa AI processes the encrypted data locally to enable features like:

  • Smart Replies: AI-generated responses based on the conversation context.

  • Real-Time Translation: On-device translation of messages into different languages.

  • Context Analysis: Insights to improve communication efficiency.

Note: All AI features are powered by a Local AI Model, ensuring no data is transferred to external servers.

5. Secure Sync Across Devices

The Matrix protocol guarantees that encrypted messages are synced across the user's devices. The Encrypted Sync Protocol ensures:

  • Messages remain encrypted during synchronization.

  • Decryption is only possible on devices with the user’s private keys.

Why This Flow Matters

  • Complete Privacy: Encryption keys remain with the user, ensuring no external entity can access the data.

  • Decentralization: The Matrix protocol avoids centralized data storage or processing.

  • AI Integration Without Compromise: Intelligent features like translations and smart replies work locally, ensuring data confidentiality.
