VoteChain

Overview

Welcome to the "VoteChain" – a pioneering platform utilizing ResilientDB and GraphQL, a cutting-edge blockchain technology, to revolutionize the landscape of electronic voting systems. Our primary focus is to ensure a secure and transparent voting process while emphasizing the significance of each voter's singular vote. VoteChain is designed to guarantee the permanence of votes, enabling every participant to cast a single vote per election. Our system strictly prohibits multiple votes, ensuring the integrity and fairness of the electoral process. One of the standout features of VoteChain is its user-friendly interface and the provision of a dedicated admin panel. Within the admin panel, a comprehensive display of all elections and their respective candidates' votes is showcased. These statistics are presented dynamically through visually intuitive representations such as bar graphs, pie charts, and polar area charts. At VoteChain, we are committed to fostering a trustworthy environment where the sanctity of each vote is upheld. Our utilization of ResilientDB technology ensures the highest standards of security, transparency, and reliability in electronic voting, empowering individuals to participate in the democratic process with confidence.

Steps to run the system

Please follow the detailed procedure below and ensure that every step is successful.

Setup Python3.10

Ensure you have Python3.10, otherwise download it and set it up as default.

Setup ResilientDB

You will need to clone the ResilientDB repo to get started:

git clone https://github.com/resilientdb/resilientdb.git

Then navigate inside the ResilientDB directory:

cd resilientdb

Install dependencies:

sh INSTALL.sh

Run ResilientDB KV Service (this may take a few minutes for the first time):

./service/tools/kv/server_tools/start_kv_service.sh

Setup Crow HTTP server, SDK, and GraphQL server

You will need to clone the ResilientDB GraphQL repo to get started:

git clone https://github.com/Amoolya-Reddy/ResilientDB-GraphQL

Then navigate inside the ResilientDBGraphQL directory:

cd ResilientDB-GraphQL

Install the Crow dependencies:

sudo apt update sudo apt install build-essential sudo apt install python3.10-dev sudo apt install apt-transport-https curl gnupg

Build Crow HTTP server (this may take a few minutes for the first time):

bazel build service/http_server:crow_service_main

Start the Crow HTTP server:

bazel-bin/service/http_server/crow_service_main service/tools/config/interface/service.config service/http_server/server_config.config

Create virtual environment for the Python SDK:

python3 -m venv venv –without-pip

Activate the virtual environment:

source venv/bin/activate

Install pip in the virtual environment for the Python dependencies:

curl https://bootstrap.pypa.io/get-pip.py | python

Install the Python dependencies:

pip install -r requirements.txt

Start the GraphQL server:

python3 app.py

Setup VoteChain

Follow these steps to set up the development environment and run the application locally.

Prerequisites

Before you begin, make sure you have the following software installed on your machine:

1. Node.js - Download and install Node.js from https://nodejs.org/

2. npm (Node Package Manager) - npm is included with Node.js. Ensure that you have the latest version by running the following command in your terminal:

   npm install
   

Clone the Repository

Clone this Git repository to your local machine using the following command:

git clone https://github.com/Kri-hika/vote-chain.git

Install Dependencies
