FfhsBlkVotingSystem

This project was generated with Angular CLI version 15.0.4.

Description

This project serves as a proof-of-concept for a e-voting system based on the Ethereum blockchain. It has very basic function, no security or whatsoever but it shows that the possibility to create a secure, transparent and anonymous e-voting platform, exists.

The project was created as part of a term paper in the module "Blockchain" at the FFHS in the B.Sc. Computer Science program.

Prerequisites

1. Install Ganache (https://trufflesuite.com/ganache/)
   1. Create a new Ethereum workspace
      1. Name: be creative :)
      2. Hostname: Choose your localhost (127.0.0.1)
      3. Port: 7545
      4. Others can be left with default values
   2. There should be some test accounts now
2. Install MetaMask extension for your Browser (https://metamask.io)
   1. click on import wallet
   2. copy your 12-word MNEMONIC from Ganache and insert them in Metamask
   3. Choose your password and click "import"
   4. Open Metamask extension and open the networks-dropdown
   5. click on "add network" -> manual
      1. name: choose something
      2. RPC-URL: http://127.0.0.1:7545
      3. Chain ID: 1337
      4. Currency symbol: ETH
   6. You should now see your first Account with the same amount of ETH as in Ganache.
3. git clone this project
4. Open Ganache, Go to Settings->Workspace and click on Add Project. Import the truffle-config.js, save and restart the network.
5. In ganache, go to Contracts and look if the Vote Contract is deployed. If this is not the case, fist do the Install section and after that, run the commands in the Troubleshoot section.
6. Install Node (https://nodejs.org/en/) and npm if not already installed on your computer

Installation

This project runs on Node version 16. Use Node Version Manager (https://github.com/nvm-sh/nvm) to change the version nvm install 16.13.2 && nvm use 16.13.2

cd inside the cloned Repository and run npm install to install all the dependencies.

Run npm run start --open to start the application. You find further information on the home-page.

Troubleshooting

If there are some problems with the contracts, check if the /truffle/build/contracts folder is not empty. You can also look into Ganache/Contracts and see if there is a Contract deployed.

Try to recompile the contracts:

1. cd truffle
2. truffle compile
3. truffle migrate --network development

Sometimes there is a problem with installing truffle, if you don't have the truffle commands, just try to install it globally with npm install -g truffle
