e-MergeCampus

e-MergeCampus is a comprehensive and innovative platform designed to streamline and enhance various essential services within a college campus. By leveraging decentralized technologies such as Ethereum blockchain and IPFS, e-MergeCampus ensures data security, transparency, and efficiency in managing campus resources and interactions.

Features

Steps to setup and run this Dapp in localhost:

1. Fork and clone this repo in local machine.
2. Run npm install in the in the project directory. This would install all dependencies.
3. Download Ganache from the official website. Also add & setup MetaMask in browser. We recommend you to follow this.
4. Install truffle by following this.
5. Start Ganache, create a New Workspace, and add your project by going to the src directory and selecting truffle-config.js. After this, save this workspace. This would start Ganache with 10 ethereum accounts, containg 100 ether each.
6. Now go to src directory, open a terminal and run truffle migrate --reset. This would compile the smart contracts and deploy the contracts in the local blockchain (Ganache).
7. Open MetaMask in your browser and select the network to custom RPC. Here, add a new network. For this, the RPC URL should be the URL shown in your Ganache. The chain id would be the same as the network id in Ganache.
8. Now select the first account shown in Ganache, and click on the key icon. This would bring up the private key for the account. Copy this private key. Now go to MetaMask (the network should be the custom network you just created), and click on import account. Paste the previously copied private key and and click on import.
9. MetaMask now should be showing the address of the first Ganache account with 100 ether in it. This is your college admin account. The one who deploys the contracts in always the admin.
10. Run npm start in the main project directory. This would start the frontend.

Steps to carry out the transactions in localhost:

At the start, admin is both the librarian and canteen owner.

1. Import some more accounts from Ganache into MetaMask. Go to Admin section in the navbar of the web-application. Now, make one of the newly imported accounts the librarian. Also change the Canteen Owner. (This step is optional, it's just a feature to change the librarian and canteen owner, in case the college authorities want to authorize someone else for managing these sections.)
2. Now the respective addresses can perform the desired transactions. The addresses (other than admin, librarian and canteen owner) can be considered as students.

Try changing accounts in MetaMask (and then reloading the page) to see which account is authorized to perform the transactions in the page. If an account isn't authorized to perform a certain transaction, the respective button will appear disabled.

Technologies used: (Development)

1. Ethereum Blockchain
   
2. IPFS
   
3. Web browser extension Metamask (recommended) or Nifty wallet.
   
4. Truffle
   
5. React (Html5, Css3, Bootstrap v5.1)
   
6. Node.js (web3.js)
   
7. Ganache
   

Technologies used: (Production Build)

1. The previous technologies used during development
2. Front-end deployment: Netlify
   
3. Back-end deployment: Infura
   

---

Note: Using Brave browser will save the effort to add and setup Metamask as it has its own built-in wallet.

Note: Wait for the previous (or pending) transactions to be completed before attempting any further transactions. This is because transactions take time to mine, forwarding the same transaction requests before completion of the previous, may result in an undesired output.
