Blockchain

# Blockchain-Based Student-Teacher-Admin Network A decentralized application (DApp) for managing academic interactions securely on the blockchain. ## Technology Stack - **Blockchain**: Solidity, Ganache - **Frontend**: HTML5, CSS3, JavaScript, Web3.js - **Wallet**: MetaMask ## Prerequisites 1. **Google Chrome** with [MetaMask Extension](https://metamask.io/) installed. 2. [Ganache](https://trufflesuite.com/ganache/) (Quickstart workspace). 3. VS Code (to edit code if needed). ## Setup & Deployment Steps ### 1. Setup Blockchain (Ganache) 1. Open **Ganache** and click **"Quickstart"**. 2. Note the **RPC Server** URL (usually `HTTP://127.0.0.1:7545`) and the **Chain ID** (usually `1337`). ### 2. Configure MetaMask 1. Open MetaMask and add a new network manually: - **Network Name**: Ganache Local - **RPC URL**: `HTTP://127.0.0.1:7545` - **Chain ID**: `1337` - **Currency Symbol**: ETH 2. Import an Account: - Copy a **Private Key** from one of the accounts in Ganache. - Initialise MetaMask -> Click Circle Icon -> Import Account -> Paste Private Key. ### 3. Deploy Smart Contract (Remix IDE) 1. Go to [Remix IDE](https://remix.ethereum.org/). 2. Create a new file `UnifiedNetwork.sol` and copy the content from the local `UnifiedNetwork.sol` file in this folder. 3. **Compile**: Go to "Solidity Compiler" tab -> Click "Compile UnifiedNetwork.sol". use parias evm version only 4. **Deploy**: - Go to "Deploy & Run Transactions" tab. - Set **Environment** to **"Injected Provider - MetaMask"**. (Make sure MetaMask is connected to Ganache). - Click **"Deploy"**. 5. **Copy Address**: After deployment, scroll down to "Deployed Contracts", copy the contract address (e.g., `0x123...`). ### 4. Connect Frontend 1. Open `app.js` in this folder. 2. Replace `"YOUR_CONTRACT_ADDRESS_HERE"` with the address you just copied. ```javascript const contractAddress = "0xYourCopiedAddress..."; ``` 3. Save the file. ### 5. Run the Application 1. You can simply double-click `index.html` to open it in Chrome (or use Live Server extension in VS Code for better experience). 2. **Login Admin**: The account used to deploy the contract is the **Admin**. Connect with that account on `index.html`. 3. **Add Teacher**: Use Admin dashboard to register a new Teacher address (pick another address from Ganache). 4. **Login Teacher**: Switch MetaMask account to the Teacher address, reload `index.html` and login. 5. **Add Student**: Use Teacher dashboard to register a Student address. 6. **Login Student**: Switch MetaMask account to Student address, reload `index.html` and login. ## Troubleshooting - **"Connection Failed"**: Ensure Ganache is running and MetaMask is on the correct network. - **"Contract Connection Failed"**: Verify `contractAddress` in `app.js` matches the deployed address in Remix. 16/12/2025 Final Optimizations Admin dash board required features - It should contain details about different departments like CSE,ECE,EEE,CIVIL,MECH,AI&ML,AI-DS,CDS and more - Admin should give an access to students that to see notifications - admin block should have an unique design than others Teacher dashboard required features - access to upload Fee details update - Access to upload (materials, notes & previous papers, belongs to different subjects) - access to paste links - to send notifications about every information (to give updates) - to assign results to each student - access to prepare time table of examinations - access to prepare time table of each department classes - Behaviour documentation of Student - to give info about carrer implementation about jobs realated to government and private - to assign weekly challenges to students Studentb Dashboard required features - to take weekly challenges - to ask questions in AI Assiatant - to check fee receipt & verifications - to Check results - to give feedback about each faculty - emmergency communication purpose of studies,sports,projects & about issues both offical & personal - to check carrer implemtation about jobs related to both government & private 17-12-2025 - Upload login page to every Dashboard (Admin,Teacher,Student)
