Develop your own blockchain and decentralized network using the JavaScript programming language
More Information

  • Build a consensus algorithm so that all the nodes in a network have the same data
  • Create a proof of work to secure your blockchain network
  • Mine new blocks and secure them in the blockchain
  • Understand how transactions are created and made immutable inside a block
  • Find out how block explorers work and how to access your new blockchain through a block explorer
  • Discover how blockchain and cryptocurrency addresses retain a value amount
  • Get to grips with how new blocks are broadcasted to the entire blockchain network and how the data inside the blockchain network is kept consistent across all the nodes
  • Understand how to develop important blockchain features
About In this course, you will learn how to build your own blockchain and decentralized blockchain network by using the JavaScript programming language. By developing your own blockchain, you will discover the working of blockchain technology and how decentralized blockchain networks function. In addition to this, you’ll get to grips with how the code behind these technologies works, along with exploring why blockchain is a secure and valuable technology.

As you progress, this course will help you understand why decentralization is an important feature for securing the blockchain. To build on your knowledge, you’ll get up to speed with the whole process of storing, securing, and validating data/transactions on the blockchain. The course covers ES6 code to ensure that you grasp the fundamental concepts effectively.

By the end of this course, you will have built your own blockchain prototype in code.

All codes and supporting files are available at-


  • Build your own fully functional blockchain prototype
  • Learn how the code behind blockchain technology works
  • Discover why blockchain technology is a secure option for storing data
  • Understand how a decentralized blockchain network functions
