This document provides an overview of the system architecture, including the key components and their interactions. 6 | 7 | ## Architecture Components 8 | 9 | 1. **Frontend**: 10 | - Built using modern JavaScript frameworks (e.g., React, Vue.js). 11 | - Communicates with the backend via RESTful APIs. 12 | - Provides a user-friendly interface for interacting with the platform. 13 | 14 | 2. **Backend**: 15 | - Developed using Python (Flask/Django) or Node.js (Express). 16 | - Handles business logic, user authentication, and data management. 17 | - Interacts with the blockchain through smart contracts. 18 | 19 | 3. **Smart Contracts**: 20 | - Deployed on a blockchain (e.g., Ethereum, Binance Smart Chain). 21 | - Responsible for managing DeFi functionalities, NFT transactions, and DAO governance. 22 | - Written in Solidity or Vyper. 23 | 24 | 4. **Database**: 25 | - Utilizes a relational database (e.g., PostgreSQL, MySQL) or NoSQL database (e.g., MongoDB) for storing user data, transaction history, and application state. 26 | - Ensures data integrity and supports complex queries. 27 | 28 | 5. **AI Module**: 29 | - Implements machine learning algorithms for personalized financial insights and fraud detection. 30 | - Processes user data to enhance wallet functionalities. 31 | 32 | 6. **Cross-Chain Bridge**: 33 | - Facilitates asset transfers between different blockchain networks. 34 | - Ensures secure and efficient cross-chain transactions. 35 | 36 | 7. **Security Layer**: 37 | - Implements advanced security protocols, including biometric authentication and multi-signature wallets. 38 | - Protects user assets and sensitive information. 39 | 40 | ## Data Flow 41 | 42 | 1. Users interact with the frontend application. 43 | 2. The frontend sends requests to the backend API. 44 | 3. The backend processes the requests, interacts with the database, and communicates with smart contracts on the blockchain. 45 | 4. Smart contracts execute transactions and return results to the backend. 46 | 5. The backend sends responses back to the frontend for user display. 47 | 48 | ## Conclusion 49 | 50 | The modular architecture of the Nexus Exo Innova platform allows for easy integration of new features and technologies, ensuring that the system can evolve with the needs of its users and the blockchain ecosystem. 51 | -------------------------------------------------------------------------------- /tests/test_security.py: -------------------------------------------------------------------------------- 1 | # tests/test_security.py 2 | 3 | import unittest 4 | from src.security.biometric_auth import BiometricAuth 5 | from src.security.multi_signature import MultiSignatureWallet 6 | 7 | class TestBiometricAuth(unittest.TestCase): 8 | def setUp(self): 9 | self.biometric_auth = BiometricAuth() 10 | 11 | def test_register_user(self): 12 | self.biometric_auth.register_user(user_id="user_001", biometric_data="fingerprint_data_001") 13 | self.assertIn("user_001", self.biometric_auth.users) 14 | 15 | def test_authenticate_user_success(self): 16 | self.biometric_auth.register_user(user_id="user_001", biometric_data="fingerprint_data_001") 17 | result = self.biometric_auth.authenticate_user(user_id="user_001", biometric_data="fingerprint_data_001") 18 | self.assertTrue(result) 19 | 20 | def test_authenticate_user_failure(self): 21 | self.biometric_auth.register_user(user_id="user_001", biometric_data="fingerprint_data_001") 22 | result = self.biometric_auth.authenticate_user(user_id="user_001", biometric_data="wrong_data") 23 | self.assertFalse(result) 24 | 25 | class TestMultiSignatureWallet(unittest.TestCase): 26 | def setUp(self): 27 | self.multi_sig_wallet = MultiSignatureWallet(required_signatures=2) 28 | 29 | def test_create_transaction(self): 30 | transaction_data = {"amount": 100, "to": "recipient_address"} 31 | transaction_id = self.multi_sig_wallet.create_transaction(transaction_data) 32 | self.assertIsNotNone(transaction_id) 33 | 34 | def test_add_signature(self): 35 | transaction_data = {"amount": 100, "to": "recipient_address"} 36 | transaction_id = self.multi_sig_wallet.create_transaction(transaction_data) 37 | self.multi_sig_wallet.add_signature(transaction_id, signer_id="signer_001", signature="signature_001") 38 | self.assertIn("signer_001", self.multi_sig_wallet.signatures[transaction_id]) 39 | 40 | def test_execute_transaction(self): 41 | transaction_data = {"amount": 100, "to": "recipient_address"} 42 | transaction_id = self.multi_sig_wallet.create_transaction(transaction_data) 43 | self.multi_sig_wallet.add_signature(transaction_id, signer_id="signer_001", signature="signature_001") 44 | self.multi_sig_wallet.add_signature(transaction_id, signer_id="signer_002", signature="signature_002") 45 | self.assertIn(transaction_id, self.multi_sig_wallet.transactions) 46 | 47 | if __name__ == '__main__': 48 | unittest.main() 49 | -------------------------------------------------------------------------------- /docs/user_guide.md: -------------------------------------------------------------------------------- 1 | # User Guide 2 | 3 | ## Introduction 4 | 5 | Welcome to the Nexus Exo Innova platform!
