# Architecture

> The six-layer Qubit Foundation stack for energy data infrastructure

# Architecture Overview

The Qubit Foundation employs a comprehensive six-layer architecture designed to handle the full lifecycle of energy data - from ingestion and processing to optimization and user interaction. Each layer builds upon the previous, creating a robust, scalable infrastructure for the energy transition.

## The Six-Layer Stack

<Steps>
  <Step title="Layer 1: Data Foundation">
    **Standardization and Ingestion**

    *Status: In Production*
  </Step>

  <Step title="Layer 2: Prediction Engine">
    **AI-Powered Forecasting**

    Production-ready machine learning models that predict energy generation, consumption, and grid conditions.

    *Status: In Production*
  </Step>

  <Step title="Layer 3: Optimization Engine">
    **Intelligent Resource Management**

    Mathematical optimization algorithms that determine optimal resource allocation and scheduling.

    * EV fleet charging schedule optimization with priority and tariff-aware scheduling
    * Battery storage peak shaving with two-pass dispatch algorithm
    * Multi-objective optimization balancing cost, carbon, and peak reduction
    * Native integration with Layer 1 tariff schemas and Layer 2 forecasts

    *Status: In Production*
  </Step>

  <Step title="Layer 4: Coordination Layer">
    **Command Dispatch and Asset Orchestration**

    Converts Layer 3 optimization schedules into real-time device commands with protocol translation and state management.

    * Dispatch engine converting schedules to timed commands with lifecycle tracking
    * OCPP-aligned EV charger and battery state machines
    * Protocol adapters for OCPP (EV chargers) and Modbus (batteries)
    * Typed event bus for real-time coordination across components

    *Status: In Production*
  </Step>

  <Step title="Layer 5: Settlement Layer">
    **Economic Verification and Settlement**

    Cryptographically secure systems for energy transaction verification and economic settlement.

    * Blockchain-based energy certificates
    * Automated payment and settlement
    * Carbon credit tracking and verification
    * Renewable energy credit management

    *Status: Research Phase*
  </Step>

  <Step title="Layer 6: Interface Layer">
    **User Experience and APIs**

    Intuitive interfaces and APIs that make energy data accessible to end users, developers, and applications.

    * Developer APIs and SDKs
    * Consumer mobile and web applications
    * Utility operator dashboards
    * Third-party integration endpoints

    *Status: Planning Phase*
  </Step>
</Steps>

## Deployment Models

The Qubit Foundation architecture supports multiple deployment patterns:

### Cloud-Native

* Full stack deployment on AWS, GCP, or Azure
* Auto-scaling and managed services
* Global edge deployment for low latency

### Hybrid

* Critical components on-premises
* Non-critical processing in the cloud
* Data sovereignty compliance

### Edge-First

* Local processing for real-time requirements
* Minimal cloud dependencies
* Offline operation capabilities

### Community

* Distributed deployment across participants
* Shared infrastructure costs
* Collective ownership model

## Integration Patterns

<Warning>
  The Qubit Foundation is designed for **production energy systems**. Always follow proper safety protocols and testing procedures when integrating with live grid infrastructure.
</Warning>

Common integration approaches:

1. **Schema-First**: Start with standardized data models
2. **Connector-Based**: Use protocol-specific adapters
3. **API-Driven**: RESTful and GraphQL interfaces
4. **Event-Streaming**: Real-time data pipelines
5. **Batch Processing**: Historical data analysis

## Performance Characteristics

The architecture is designed to handle:

* **Throughput**: 10M+ messages per second per node
* **Latency**: Sub-millisecond for critical operations
* **Scale**: Billions of connected devices
* **Availability**: 99.99% uptime with automatic failover
* **Storage**: Exabyte-scale time-series data

## Security Model

<Tip>
  All Qubit Foundation components implement **zero-trust security** by default, with end-to-end encryption and cryptographic verification at every layer.
</Tip>

Security is built into every layer:

* **Layer 1**: Device authentication, data encryption, schema validation
* **Layer 2**: Model integrity verification, secure computation
* **Layer 3**: Optimization result verification, tamper-proof algorithms
* **Layer 4**: Byzantine fault tolerance, cryptographic consensus
* **Layer 5**: Smart contract audits, economic security mechanisms
* **Layer 6**: OAuth 2.0, API rate limiting, user privacy controls
