Description

Have you ever heard of Crowd Sale in Cryptocurrencies?

Are you running a startup and looking to raise fund?

How about raising a funding from people all over the globe?

Well, many startups in the world are turning their business ideas into a funded business through crowdsale. Cryptocurrencies provide you the best way to crowd fund you business idea while keeping the funders safe. In this course I will teach you how to build a crowd sale or crowd fund application (aka Initial Coin Offering) on top of Ethereum Blockchain.

In this course I will show you a step by step process of creating a Crowd sale application.

We will first setup the Mist Wallet
Then we will setup or code editor
Then we will start writing the code and take you from smallest application to the full application.

At the end of this course you will be able to launch your own ICO application in Ethereum and also extend it as per your need.

Who this course is for:

Anyone interested in being Ethereum Developer
Anyone interested in building decentralized application (DApps)
Anyone interested in Learning Solidity Language for Smart Contracts
Anyone interested in learning how to build ICO (Crowdsale)

Introduction& Overview of the Course Preview 04:02

This will be the introductory lecture where I will introduce myself & take you to the entire course and explain what we are going to learn here.

Flow Chart: Understanding What We will Build Preview 05:36

In this lecture, we will go through the Flow chart of the crowd sale application to understand how exactly the crowd sale will work in Blockchain.

Background: What is Blockchain, Ethereum & Smart Contract? Preview 10:59

In this lecture we will introduce the Blockchain, Ethereum & Smart Contracts to people who are new to this technology to revise their concepts.

Background: What is Solidity & Ethereum Virtual Machine? Preview 04:03

Here I will explain the Solidity & Ethereum Virtual Machine at very basic level.

Building Crowd-sale Application in Solidity 10 lectures

Setting up Development Environment Preview 08:29

Here we will setup a Mist Wallet & Visual Studio as well as Sublime Text for deploying, writing & highlight the source code.

Creating Token For Crowd Sale - Part 1 Preview 09:59

In this lecture we will create the Virtual Token That we will transfer in exchange of the Investment or sale. Ethereum Blockchain will help us tracking the ownership of the Virtual token to track the investment or sale.

Creating Token For Crowd Sale - Part 2 Preview 12:32

Here we will continue the previous lecture by completing the Token creation.

Creating Basic Crowd Sale Application - Part 1 Preview 11:29

Here In this lecture we will create the basic crowd sale application by defining the state variables, Modifiers, Events etc.

Creating Basic Crowd Sale Application - Part 2 Preview 11:01

In this lecture we will complete the the basic crowd sale application from scratch.

Writing Contribute Function in Crowd Sale Application Preview 16:10

In this lecture we will write the most important function Contribute through which funders will be able to contribute to the crowd sale.

Writing Refund Function (In case funding fail) Preview 06:53

Here we will define the refund function through which contributors will be able to claim the refund in case the funding is unsuccessful.

Writing Funding Status Check & Payout Function Preview 06:30

Here we will write the function to check if the funding is successful or not and if successful then initiate the payout to the beneficiary.

Executing the Crowd Sale App - Part 1 Preview 07:46

Here we will execute the token first and get it's address. This token will be issued to the funders for their contribution or purchase.

Executing the Crowd Sale App - Part 2 Preview 14:43

Here we will execute the main crowd sale application and execute the contribute function 3 times to mark a successful crowd sale. We will see how the GDX tokens & ethers will be reflected in the wallet of the contributor, crowd sale & beneficiary's account.
