Description

Blockchain is a distributed database that enables permanent, transparent, and secure storage of data. Cryptocurrency is a digital currency which can be used to transfer assets from person to person in a decentralized way. If you want to have a perfect entry in the world of decentralized databases and applications by learning about Blockchain and cryptocurrency, then go for this course.

This comprehensive 2-in-1 course teaches you everything you need to know about Blockchain, cryptocurrencies, and its platforms. Each and every concept is covered in a detailed manner explaining you the topics such as Bitcoin, Ethereum, Hyperledger, Ripple, Litecoin, Bitcoin Trading, Mining, and ICO along with its working / implementation. You will firstly create a mock blockchain using JavaScript code.  You will then write smart contracts with Solidity and implement it on various blockchain platforms. You will also learn how to build ethereum and blockchain-based applications and secure them using the cryptography techniques. Lastly, you will create a gambling application using ETH network smart contracts.

Contents and Overview

This training program includes 2 complete courses, carefully chosen to give you the most comprehensive training possible.

In the first course, Blockchain Development for Beginners, you will begin with a brief introduction to what blockchain technology is and the potential this technology has to change the world around us. You will then dive into seeing how the blockchain functions by creating a mock blockchain using JavaScript code. Next, you will learn the Solidity coding language which is essential for developing blockchain dApps and use your Solidity skills to conduct token generation. Finally you will use both Solidity and JavaScript skills to compile and deploy a smart contract, which will then be followed by developing an interactive front-end for it.

In the second course, Blockchain Real World Projects, you will begin with the development of a basic application using Blockchain and mining blocks. You will then build the Bitcoin codebase and your own currency/tamper-proof DB. Using Hyperledger, you will also implement various blockchains to create a supply chain application. Next, you will explore ERC20 standards to create an ERC20 smart contract and you will learn to improve its standards with ERC22 to develop first ICO. Finally, 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 will also be able to design and build you own ethereum and blockchain-based applications.

We have the best work of the following esteemed author(s) to ensure that your learning journey is smooth:

●        Daniel Wise has worked in various career paths both domestic and abroad, and since then he focused on the tech field. He began his journey learning programming on Treehouse while he lived abroad in Busan, South Korea. His interest in tech began to grow after being accepted into the Flatiron School and returned to the USA to pursue this new career. He has gained experience in the tech field not just on the development side but on the business side as well. His experience and hard work running an indie game studio (known as Ultima Game Studios) paid off when their game demo was chosen to be exhibited at PAX East 2017. This experience in the gaming industry allowed him to utilize his talents in both development and marketing.
Currently he is a busy freelancer, handling projects in Unity development and also writing technical lessons to share his knowledge online. He believes that it is his duty to help others learn about tech/coding while creating projects and learning new things himself. He also assesses promotional ideas and strategies for those looking to promote their businesses online.

Sriharsha Bingi is currently pursuing his masters in computer science at New Jersey Institute of technology, NJ. Being a philomath, he has been into cryptocurrencies, investments, and data science since 3 years. He did his schooling in India and Oman. His passion towards cryptocurrencies grew from the year 2016. That interest started multiplying ever since he got awestruck by the amount of research big companies are doing and spending money on it, in the year 2017. 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 world financial center, Manhattan, New York as a blockchain developer. In the road of constantly honing his skills in 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 still less. He has developed a functional demo using blockchain technology for BdiPlus company in world financial center, Manhattan and now he would like to share his experience and knowledge with us.
