Description

Blockchain is a revolution promising a new world without middlemen. This course will provide you with all the relevant concepts related to cryptocurrencies, smart contracts, and blockchain in order to build your own decentralized applications.

You will begin with the development of a basic application using Blockchain and mining blocks. Moving further, you will build the Bitcoin codebase and you will be able to build your own currency/tamper-proof DB. Using Hyperledger you will implement various blockchains to create a supply chain application. You will explore ERC20 standards to create an ERC20 smart contract and you will also learn to improve its standards with ERC22 to develop its first ICO. Lastly, you will create a gambling application using ETH network smart contracts. Each project will teach you just enough about blockchain to be productive right away.

By the end of this course, you will not only be able to tackle common issues in the blockchain ecosystem but you'll also design and build reliable, scalable, distributed systems

About the Author

Sriharsha Bingi has been into cryptocurrencies, investments, and data science for 3 years. He did his schooling in India and Oman. His passion for cryptocurrencies grew from the year 2016. That interest started multiplying in 2017, when he was awestruck by the amount of research big companies are doing and the money they're spending on it. That is when he realized that the blockchain technology is going to revolutionize the World. Technology has to evolve continuously, says Harsha.

At present he is working in the World Financial Center, Manhattan, New York as a blockchain developer. In the course of constantly honing his skills in the blockchain technology, he wants to share his knowledge with us. As the need for blockchain developers is exponentially increasing the people who are actually trained to develop are getting fewer. He has developed a functional demo using blockchain technology for BdiPlus, a company in the World Financial Center, Manhattan and now he would like to share his experience and knowledge with us

Who this course is for:
  • If you are interested in building blockchain decentralized applications from scratch, this course is for you. It begins with the basics and will equip you with the ability to build intermediate projects.
