DataMgmt Node

This project implements a decentralized system for enterprise data management and sharing, leveraging blockchain technology, peer-to-peer networking, and flexible data storage solutions.

Features

• Blockchain integration with support for EVM-compatible chains
• Peer-to-peer data sharing using the Gun P2P network
• Flexible data storage with support for both RocksDB and LevelDB
• Token management for native and custom tokens
• Payment processing for data transactions
• Compliance management and event logging on the blockchain
• Plugin system for extensibility
• Internal and external APIs for system interaction

Prerequisites

• Python 3.7+
• pip (Python package manager)

Installation

1. Clone the repository:

   git clone https://github.com/your-repo/decentralized-data-system.git
   cd decentralized-data-system
   

2. Install the required dependencies:

   pip install web3 pygundb cryptography aiohttp
   

3. Install either RocksDB or LevelDB:

   • For RocksDB:

     pip install python-rocksdb
     

   • For LevelDB:

     pip install plyvel
     

Configuration

Create a configuration file config.py with the following content:

from node import NodeConfig

config = NodeConfig(
    blockchain_type='evm',
    blockchain_url='https://mainnet.infura.io/v3/YOUR-PROJECT-ID',
    private_key='your_private_key_here',
    native_token_address='0x...',
    db_path='./nodedb',
    sqlite_db_path='./sqlite.db',
    p2p_port=8000,
    plugin_dir='./plugins',
    node_id='node1',
    node_signature='signature_here',
    initial_peers=['http://peer1.example.com', 'http://peer2.example.com']
)

Replace the placeholder values with your actual configuration.

Usage

1. Start the node:

   python main.py
   

2. Interact with the node using the internal and external APIs:

   • Internal API: http://localhost:8080
   • External API: http://localhost:8081

API Endpoints

Internal API

• GET /balance/{address}: Get the balance of an address
• POST /transfer: Transfer tokens

External API

• POST /share_data: Share data with other nodes
• GET /verify_data/{data_hash}: Verify shared data
• GET /get_compliance_history: Retrieve compliance event history

Extending Functionality

To add new features or customize behavior, you can create plugins in the plugins directory. Each plugin should be a Python module with a class that inherits from a base plugin class (to be implemented).

Security Considerations

• Ensure that your private keys and sensitive data are stored securely.
• Use HTTPS for all API endpoints in production.
• Regularly update dependencies to patch any security vulnerabilities.
• Implement proper access control and authentication mechanisms for your APIs.
