Ultimate Blockchain

Course Description

Learn how to build a reference implementation of a blockchain in Go. The goal of the class is to provide foundational knowledge about the different aspects of blockchain nodes and wallets. From the beginning, you will pair program with the instructor, walking through the design philosophies and guidelines used to engineer the code. With each new feature, you will learn more about the different aspects of a blockchain and how they all work together. In the class, you will write both a wallet and blockchain node that can work in a distributed way.

Check out the Ardan blockchain project on GitHub.

Over the course of 5 days we will cover:

  • Digital accounts with electronic signatures and verification
  • Transaction distribution and synchronization between computers
  • Redundant storage of a single ledger on different computers
  • Consensus by different computers to process and store new transactions
  • Detection of any forgery to past transactions


An intermediate understanding of the Go programming language is recommended. Students will derive the most value if they have taken our Ultimate Go and Ultimate Service classes.

We also recommend taking this free blockchain class from Patrick McCorry.
