# Decentralized-Voting-App
This is a decentralized app made to run on the ethereum virtual machine (EVM). It enables the client to vote for one candidate out of several and show the number of votes for each candidate. The app has been written using Solidity language, developed for writing dapps on EVM. The client has been written and run on nodejs. This project helped in improving my understanding of how decentralized application are implemented and how they work.
### Screenshot
A scrrenshot of the client is presented below -
### Instructions
Get the instance address of the Voting contract instance -
```
$node
> Web3 = require('web3')
> web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));
> code = fs.readFileSync('Voting.sol').toString()
> solc = require('solc')
> compiledCode = solc.compile(code)
> abiDefinition = JSON.parse(compiledCode.contracts[':Voting'].interface)
> VotingContract = web3.eth.contract(abiDefinition)
> byteCode = compiledCode.contracts[':Voting'].bytecode
> deployedContract = VotingContract.new(['Rama','Nick','Jose'],{data: byteCode, from: web3.eth.accounts[0], gas: 4700000})
> deployedContract.address
> contractInstance = VotingContract.at(deployedContract.address)
```
Copy the hash output from `> deployedContract.address` and paste in `index.js` -
`contractInstance = VotingContract.at('0x3e22ae8404a1fb45473c04c9062b3afc90d5cd82')`
Start the EVM by running `node_modules/.bin/testrpc`
