Blockchain technology is among the most exciting developments in the IT industry in many years. Often shrouded in mystery (including who the person is who developed it), today blockchain is most well known as the technology that underpins cryptocurrencies, the most famous of those being Bitcoin. But blockchain’s distributed-ledger technology holds the promise to revolutionize the way businesses and governments create and maintain important records of transactions of all kinds, whether it’s contracts, deeds, or any other types of activity for which an inviolable record must be maintained.

In this learning path, intended for developers and programmers who have a basic understanding of web-based applications, you learn the fundamentals of a blockchain and Decentralized Applications, or DApps, and how data that’s stored there is considered immutable—all but impossible to tamper or change, and if an attempt were made, it would be detected immediately. You’ll begin by learning blockchain’s terminology and then explore how it’s used in cryptocurrency. You’ll also look at blockchain deployment models, Consensus Algorithms, blockchain supply chain models, DApp modeling and development, as well as development environment requirements for blockchain coding. You’ll examine the theory and concepts such as how many distributed computer hosts, called nodes, add bits of information in “chains” of highly encrypted blocks. When you’ve completed this learning path, you’ll have a firm understanding of blockchain basics and a solid foundation from which to continue learning and dive deeper into this fascinating field.

What you’ll learn—and how you can apply it

  • The history of Bitcoin and blockchain technology
  • Technical structure of a Blockchain
  • Basics of how a blockchain works and it architecture
  • Basic understanding of blockchain use cases in business
  • How hashing algorithms work
  • Understand Decentralized Applications, or DApps, architecture and design
  • Migrate centralized database systems into DApps
  • Understand how blockchain manages assets such as cryptocurrencies, and other assets
  • Build an end-to-end transaction flow for blockchain supply chains
  • Basic understanding of cryptography via hands-on exercises
  • The development environment and requirements for blockchain application development
