Professional Blockchain
5 days  (Instructor Led Online)  |  Programming

Course Details


This Professional Blockchain training course provides an introduction to all the relevant concepts of blockchain technology. You will get detailed insights into how blockchain works and the techniques that are used to build it.

In this course, you will learn to develop decentralized applications and smart contracts using Ethereum, Solidity, Truffle, Ganache, and other relevant frameworks. Because the course provides a comprehensive knowledge of blockchain technology, it is a self-contained product that enables you to fully understand the technology.

The course will then cover decentralization, its impact, relationship with blockchain, and implementation. After this, concepts like symmetric cryptography, security services, cryptographic primitives, and stream cyphers will be covered in depth. Lessons in using OpenSSL will follow, where you can experiment with symmetric cryptography and asymmetric cryptography.

A highlight of this edition is the introduction to bitcoins and altcoins with hands-on exercises on how to install the Bitcoin client and interact with the blockchain Bitcoin. You’ll also explore smart contracts, Ethereum, solidity language, and frameworks such as Ganache, TestRPC, and Truffle for smart contract development.

By the end of this course, you’ll be an expert in the making, learning about issues delaying the maturity of blockchain technology and what lies ahead in the future.


This course will provide you with knowledge of the following:

  • Understand decentralization and its relationship with blockchain
  • Use cryptography to provide security services
  • Describe the inner workings of Bitcoin and alternative cryptocurrency
  • Implement smart contracts
  • Grasp how Ethereum blockchain works
  • Develop decentralized applications using Solidity and other frameworks
  • Examine applications of the blockchain technology beyond currencies
  • Implement blockchain solutions including Hyperledger and Corda
  • Explore the blockchain revolution, research topics and the future scope of blockchain technology professional Blockchain should be your next read if you want to stay updated with blockchain technology and develop your own distributed applications. To easily grasp the concepts explained in this course, you must have the knowledge and experience of coding in JavaScript.
