DePIN x Mobility: Smart Car Data Marketplace

This project is a modular prototype for a decentralized smart car data marketplace, built with Expo and React Native. It aims to simulate smart vehicle data, allow users to visualize and control their data sharing, and prototype a peer-to-peer marketplace with potential token incentives, as per the DeCharge Hackathon requirements.

Features

• Real-time Synthetic Car Data Simulation: Simulates key vehicle data including Speed, RPM, Fuel Level, Engine Temperature, GPS coordinates, and Diagnostic Trouble Codes (DTCs).
• Data Visualization Dashboard: Users can view their simulated car's data in real-time.
• Peer-to-Peer Data Marketplace Interface: Users can choose what data they share on a simulated marketplace.
• Prototyped Incentive Model: Placeholder for a token or incentive system to reward data contributions.
• Modular Architecture: Designed for easy extension with new data sources (e.g., real car APIs, other sensors) and features.
• Para SDK Integration: Ready for integrating Para for wallets and authentication to enhance user ownership and onchain interactions.

Getting Started

1. Install dependencies

   npm install

2. Start the app

   npx expo start

Project Structure

• app/ — Main application screens (Dashboard, Marketplace, Settings) and navigation.
• components/ — Reusable UI components.
• constants/ — App-wide constants (colors, styles, configuration).
• features/ — Modular components for specific functionalities:
  • data-simulation/ — Scripts and modules for generating/simulating car data (OBD, GPS).
  • vehicle-data/ — Handling and processing of vehicle data.
  • visualization/ — Components for displaying data (charts, maps, etc.).
• hooks/ — Custom React hooks for shared logic.
• marketplace/ — Logic and UI components for the data marketplace.
  • api/ — Mock API or integration points for marketplace interactions.
  • screens/ — Marketplace specific screens.
  • services/ — Marketplace related services.
• services/ — Core application services:
  • para-integration/ — Modules for Para SDK wallet and authentication.
  • data-manager/ — Service for managing data flows and storage.
• store/ — Global state management (e.g., Zustand, Redux).
• types/ — TypeScript type definitions for the project.
• assets/ — Static files like images, fonts.
• navigation/ — Navigation setup if not fully covered by expo-router file-based routing.
• scripts/ — Utility scripts for development and building.
• utils/ — Utility functions.

Extending

• Add new data simulation modules in features/data-simulation/.
• Integrate real car APIs by creating new services in services/.
• Develop new UI components in components/ or feature-specific UI in features/*/ or marketplace/.
