About The Project

In this project you will see all of the following concepts and the blockchain will have all of the following features below:

Blockchain Essentials

• A Proof-of-Work Algorithm to secure the network.
• Hashing algorithms to secure the data within the blockchain we are using SHA256 algotithm for hashing.
• Mine (to create) new blocks that contain transaction data.
• Create transactions and store them in blocks.
• An API/server to interact with the blockchain from the internet (We are using localhost for demo).
• Hosted on a decentralized blockchain network.
• A consensus algorithms, verifying that the network nodes have valid data and are synchronized.
• A broadcasting system, keeping the data in the blockchain network synchronized.

Built With

This section lists major frameworks that built this project using.

• NodeJs
• Bootstrap
• JQuery
• AngularJs

Getting Started

This project can run locally or on a server setting up your project locally is very easy. To get a local copy up and running follow these simple steps below.

Prerequisites

For this project nodejs is must. The official link to download and install nodejs is nodejs.org/en/download/current

• npm

npm install npm@latest -g

Installation

Installation of this project is easy.

1. Clone the repo

git clone https://github.com/mascarenhasneil/blockchain.git

2. Install NPM packages - this will install all dependencies

npm install

Usage

Using this app and starting your own block chain is very easy.

1. I have pre-created 5 nodes for this network. If needed you can add more. Do this by addding this to package.json file. For example:

node_<Number>": "nodemon --watch dev -e js dev/api.js <Port Number>  http://localhost:<Port Number>"

2. We need to run each node in different terminal so to create a network. To start the node enter this command. For node 1:

npm run node_1

Follow this by replacing the number of each node till all nodes are running.

3. I need a break, having a coffee. brb

Roadmap
