What Web3 is and how it differs from Web 1.0 and Web 2.0
The core layers of Web3 and how they work together
How to explore Web3 concepts using hands-on simulations
Why learn Web3
How the Internet Computer Protocol (ICP) extends Web3
Welcome to the Introduction to Web3 course!
This course takes a practical approach to understanding Web3. Rather than simply defining what Web3 is, we will explore how it works by breaking it down into its core layers—from blockchain infrastructure and smart contracts to decentralised applications, wallets, and user interaction.
We will move step by step through the Web3 stack, exploring how each layer connects to and builds on the one beneath it.
You will also learn how the Internet Computer Protocol, or ICP, expands this stack by providing decentralized cloud infrastructure. This allows websites, applications, and smart contracts to run directly on the blockchain with less reliance on traditional centralized servers.
To make the course more practical, each section includes links to interactive simulation labs. These activities allow you to experiment with key concepts in real time, helping you turn theoretical knowledge into practical understanding.
