The architecture is modular, allowing for easy integration of new features and enhancements. This document outlines the key components of the system architecture, their roles, and how they interact with each other. 6 | 7 | ## Key Components 8 | 9 | ### 1. **Core Layer** 10 | The Core Layer is the backbone of the QuantumPay Network, responsible for the fundamental functionalities of the system. 11 | 12 | - **Blockchain Module**: Implements the blockchain data structure, including blocks, chains, and validation mechanisms. 13 | - **Transaction Module**: Manages the creation, validation, and processing of transactions within the network. 14 | - **Consensus Module**: Implements consensus algorithms (e.g., Proof of Work, Proof of Stake) to ensure agreement among nodes on the state of the blockchain. 15 | - **Security Module**: Handles cryptographic functions, including encryption, decryption, and secure key management. 16 | 17 | ### 2. **Smart Contracts Layer** 18 | The Smart Contracts Layer allows developers to create and deploy decentralized applications (dApps) on the QuantumPay Network. 19 | 20 | - **Contract Management**: Facilitates the deployment, execution, and management of smart contracts. 21 | - **Interoperability**: Provides mechanisms for cross-chain communication and interaction with other blockchain networks. 22 | 23 | ### 3. **AI Optimization Layer** 24 | This layer leverages artificial intelligence to enhance transaction processing and network efficiency. 25 | 26 | - **Transaction Optimizer**: Uses machine learning algorithms to predict optimal transaction fees and processing times. 27 | - **Fraud Detection**: Implements AI-driven models to identify and mitigate fraudulent activities within the network. 28 | 29 | ### 4. **User Interface Layer** 30 | The User Interface Layer provides end-users with access to the QuantumPay Network through various applications. 31 | 32 | - **Web Application**: A responsive web interface for users to manage their wallets, initiate transactions, and interact with dApps. 33 | - **Mobile Application**: A mobile app that allows users to perform transactions and access their accounts on the go. 34 | 35 | ### 5. **API Layer** 36 | The API Layer exposes the functionalities of the QuantumPay Network to external developers and applications. 37 | 38 | - **RESTful API**: Provides endpoints for transaction processing, account management, and smart contract interactions. 39 | - **WebSocket API**: Enables real-time communication for applications requiring instant updates (e.g., transaction confirmations). 40 | 41 | ## System Interaction 42 | 43 | The components of the QuantumPay Network interact in a seamless manner to provide a cohesive user experience: 44 | 45 | 1. **User Interaction**: Users interact with the system through the User Interface Layer, which communicates with the API Layer to perform actions such as sending transactions or querying account balances. 46 | 2. **Transaction Processing**: When a transaction is initiated, it is sent to the Transaction Module in the Core Layer for validation and processing. The Consensus Module ensures that the transaction is agreed upon by the network. 47 | 3. **Smart Contract Execution**: If the transaction involves a smart contract, the Contract Management component executes the contract logic and updates the blockchain accordingly. 48 | 4. **AI Optimization**: The AI Optimization Layer continuously analyzes transaction patterns and network performance to provide insights and optimizations for future transactions. 49 | 50 | ## Conclusion 51 | 52 | The QuantumPay Network architecture is designed to be robust, scalable, and adaptable to the evolving needs of digital payments. By leveraging advanced technologies such as blockchain, smart contracts, and artificial intelligence, QuantumPay aims to set a new standard for secure and efficient financial transactions. 53 | 54 | For more detailed information on each component, please refer to the respective documentation files in the `docs/` directory. 55 | -------------------------------------------------------------------------------- /docs/API/authentication.md: -------------------------------------------------------------------------------- 1 | # QuantumPay API Authentication Methods 2 | 3 | This document outlines the authentication methods and protocols used to secure access to the QuantumPay API. Proper authentication is essential to ensure that only authorized users can interact with the API and perform sensitive operations. 4 | 5 | ## Overview 6 | 7 | The QuantumPay API uses token-based authentication to secure its endpoints. Users must authenticate themselves to obtain an access token, which is then used to authorize subsequent API requests. 8 | 9 | ## Authentication Flow 10 | 11 | 1. **User Registration**: Users must first create an account by providing their username, password, and email address. Upon successful registration, a user ID is generated. 12 | 13 | 2. **User Login**: After registration, users can log in to obtain an access token. The login process involves sending a request with the user's credentials. 14 | 15 | 3. **Token Generation**: Upon successful login, the server generates a JSON Web Token (JWT) that encodes the user's information and permissions. This token is returned to the user. 16 | 17 | 4. **Token Usage**: The user includes the JWT in the `Authorization` header of subsequent API requests to access protected resources. 18 | 19 | 5. **Token Expiration**: Tokens have a limited lifespan for security reasons. Users must refresh their tokens or log in again once the token expires. 20 | 21 | ## API Endpoints for Authentication 22 | 23 | ### 1.

It outlines the necessary steps, code snippets, and explanations to help you understand the transaction process. 4 | 5 | ## Overview 6 | 7 | In the QuantumPay Network, a transaction typically involves the following steps: 8 | 9 | 1. **Generate Wallet Keys**: Create a wallet with a unique public/private key pair. 10 | 2. **Create a Transaction**: Define the transaction details, including sender, receiver, and amount. 11 | 3. **Sign the Transaction**: Use the private key to sign the transaction, ensuring its authenticity. 12 | 4. **Broadcast the Transaction**: Send the signed transaction to the network for processing. 13 | 5. **Confirm the Transaction**: Wait for confirmation from the network that the transaction has been processed. 14 | 15 | ## Step 1: Generate Wallet Keys 16 | 17 | You can generate wallet keys using the `generate-keys.sh` script: 18 | 19 | ```bash 20 | ./scripts/generate-keys.sh myWallet 21 | ``` 22 | 23 | This command will create two files in the `keys` directory: 24 | - `myWallet_private.key`: Contains the private key. 25 | - `myWallet_public.key`: Contains the public key. 26 | 27 | ## Step 2: Create a Transaction 28 | 29 | Define the transaction details in your application: 30 | 31 | ```javascript 32 | const transaction = { 33 | from: '0xYourSenderAddress', // Replace with your public key 34 | to: '0xReceiverAddress', // Replace with the receiver's public key 35 | amount: 100, // Amount to send 36 | timestamp: Date.now(), // Current timestamp 37 | }; 38 | ``` 39 | 40 | ## Step 3: Sign the Transaction 41 | 42 | Use the private key to sign the transaction. You can use a cryptographic library like `crypto` in Node.js: 43 | 44 | ```javascript 45 | const fs = require('fs'); 46 | const crypto = require('crypto'); 47 | 48 | // Load the private key 49 | const privateKey = fs.readFileSync('./keys/myWallet_private.key', 'utf8'); 50 | 51 | // Sign the transaction 52 | const signTransaction = (transaction, privateKey) => { 53 | const transactionString = JSON.stringify(transaction); 54 | const sign = crypto.createSign('SHA256'); 55 | sign.update(transactionString); 56 | return sign.sign(privateKey, 'hex'); 57 | }; 58 | 59 | const signedTransaction = signTransaction(transaction, privateKey); 60 | console.log('Signed Transaction:', signedTransaction); 61 | ``` 62 | 63 | ## Step 4: Broadcast the Transaction 64 | 65 | Send the signed transaction to the network. This typically involves making an API call to the network's transaction endpoint: 66 | 67 | ```javascript 68 | const axios = require('axios'); 69 | 70 | const broadcastTransaction = async (signedTransaction) => { 71 | try { 72 | const response = await axios.post('https://api.quantumpay.network/transactions', { 73 | transaction: signedTransaction, 74 | }); 75 | console.log('Transaction broadcasted:', response.data); 76 | } catch (error) { 77 | console.error('Error broadcasting transaction:', error); 78 | } 79 | }; 80 | 81 | broadcastTransaction(signedTransaction); 82 | ``` 83 | 84 | ## Step 5: Confirm the Transaction 85 | 86 | After broadcasting, you can check the transaction status by querying the network: 87 | 88 | ```javascript 89 | const checkTransactionStatus = async (transactionId) => { 90 | try { 91 | const response = await axios.get(`https://api.quantumpay.network/transactions/${transactionId}`); 92 | console.log('Transaction Status:', response.data); 93 | } catch (error) { 94 | console.error('Error checking transaction status:', error); 95 | } 96 | }; 97 | 98 | // Replace with the actual transaction ID returned from the broadcast 99 | checkTransactionStatus('yourTransactionId'); 100 | ``` 101 | 102 | ## Conclusion 103 | 104 | This document provides a basic overview of how to perform a transaction in the QuantumPay Network. By following these steps, you can create, sign, and broadcast transactions securely. For more advanced use cases, consider exploring additional features such as multi-signature transactions, transaction fees, and error handling. 105 | 106 | For further information, refer to the official QuantumPay Network documentation. 107 | -------------------------------------------------------------------------------- /docs/developer-guide.md: -------------------------------------------------------------------------------- 1 | # QuantumPay Developer Guide 2 | 3 | Welcome to the QuantumPay Developer Guide!

It outlines the necessary steps, code snippets, and explanations to help you understand the cross-chain transaction process. 4 | 5 | ## Overview 6 | 7 | Cross-chain transactions allow users to transfer assets or data between different blockchain networks. In the QuantumPay Network, this process typically involves the following steps: 8 | 9 | 1. **Generate Wallet Keys**: Create wallets on both blockchains involved in the transaction. 10 | 2. **Create a Cross-Chain Transaction**: Define the transaction details, including sender, receiver, amount, and target blockchain. 11 | 3. **Sign the Transaction**: Use the private key to sign the transaction. 12 | 4. **Broadcast the Transaction**: Send the signed transaction to the source blockchain. 13 | 5. **Confirm the Transaction**: Wait for confirmation from the source blockchain. 14 | 6. **Complete the Transaction on the Target Blockchain**: Finalize the transaction on the destination blockchain. 15 | 16 | ## Step 1: Generate Wallet Keys 17 | 18 | You can generate wallet keys for both blockchains using the `generate-keys.sh` script: 19 | 20 | ```bash 21 | ./scripts/generate-keys.sh myWalletSource 22 | ./scripts/generate-keys.sh myWalletTarget 23 | ``` 24 | 25 | This command will create two sets of key files in the `keys` directory: 26 | - `myWalletSource_private.key` and `myWalletSource_public.key` for the source blockchain. 27 | - `myWalletTarget_private.key` and `myWalletTarget_public.key` for the target blockchain. 28 | 29 | ## Step 2: Create a Cross-Chain Transaction 30 | 31 | Define the transaction details in your application: 32 | 33 | ```javascript 34 | const crossChainTransaction = { 35 | from: '0xYourSourceAddress', // Replace with your source public key 36 | to: '0xReceiverAddress', // Replace with the receiver's public key on the target blockchain 37 | amount: 100, // Amount to send 38 | targetBlockchain: 'Ethereum', // Specify the target blockchain 39 | timestamp: Date.now(), // Current timestamp 40 | }; 41 | ``` 42 | 43 | ## Step 3: Sign the Transaction 44 | 45 | Use the private key from the source blockchain to sign the transaction: 46 | 47 | ```javascript 48 | const fs = require('fs'); 49 | const crypto = require('crypto'); 50 | 51 | // Load the private key for the source blockchain 52 | const privateKeySource = fs.readFileSync('./keys/myWalletSource_private.key', 'utf8'); 53 | 54 | // Sign the cross-chain transaction 55 | const signCrossChainTransaction = (transaction, privateKey) => { 56 | const transactionString = JSON.stringify(transaction); 57 | const sign = crypto.createSign('SHA256'); 58 | sign.update(transactionString); 59 | return sign.sign(privateKey, 'hex'); 60 | }; 61 | 62 | const signedCrossChainTransaction = signCrossChainTransaction(crossChainTransaction, privateKeySource); 63 | console.log('Signed Cross-Chain Transaction:', signedCrossChainTransaction); 64 | ``` 65 | 66 | ## Step 4: Broadcast the Transaction 67 | 68 | Send the signed transaction to the source blockchain. This typically involves making an API call to the source blockchain's transaction endpoint: 69 | 70 | ```javascript 71 | const axios = require('axios'); 72 | 73 | const broadcastCrossChainTransaction = async (signedTransaction) => { 74 | try { 75 | const response = await axios.post('https://api.sourceblockchain.network/transactions', { 76 | transaction: signedTransaction, 77 | }); 78 | console.log('Cross-Chain Transaction broadcasted:', response.data); 79 | return response.data.transactionId; // Return the transaction ID for confirmation 80 | } catch (error) { 81 | console.error('Error broadcasting cross-chain transaction:', error); 82 | } 83 | }; 84 | 85 | const transactionId = await broadcastCrossChainTransaction(signedCrossChainTransaction); 86 | ``` 87 | 88 | ## Step 5: Confirm the Transaction 89 | 90 | After broadcasting, you can check the transaction status on the source blockchain: 91 | 92 | ```javascript 93 | const checkCrossChainTransactionStatus = async (transactionId) => { 94 | try { 95 | const response = await axios.get(`https://api.sourceblockchain.network/transactions/${transactionId}`); 96 | console.log('Cross-Chain Transaction Status:', response.data); 97 | } catch (error) { 98 | console.error('Error checking cross-chain transaction status:', error); 99 | } 100 | }; 101 | 102 | checkCrossChainTransactionStatus(transactionId); 103 | ``` 104 | 105 | ## Step 6: Complete the Transaction on the Target Blockchain 106 | 107 | Once the transaction is confirmed on the source blockchain, you can finalize the transaction on the target blockchain. This may involve a similar process of broadcasting a transaction to the target blockchain: 108 | 109 | ```javascript 110 | const completeCrossChainTransaction = async (transactionId) => { 111 | try { 112 | const response = await axios.post('https://api.targetblockchain.network/complete-transaction', { 113 | transactionId: transactionId, 114 | to: '0xReceiverAddress', // Replace with the receiver's public key on the target blockchain 115 | amount: 100, // Amount to send 116 | }); 117 | console.log('Cross-Chain Transaction completed on target blockchain:', response.data); 118 | } catch (error) { 119 | console.error('Error completing cross-chain transaction on target blockchain:', error); 120 | } 121 | }; 122 | 123 | await completeCrossChainTransaction(transactionId); 124 | ``` 125 | 126 | ## Conclusion 127 | 128 | This document provides a basic overview of how to perform a cross-chain transaction in the QuantumPay Network. By following these steps, you can create, sign, and broadcast cross-chain transactions securely. For more advanced use cases, consider exploring additional features such as multi-signature transactions, transaction fees, and error handling. 129 | 130 | For further information, refer to the official QuantumPay Network documentation. 131 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | Apache License 2 | Version 2.0, January 2004 3 | http://www.apache.org/licenses/ 4 | 5 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 6 | 7 | 1.
