Infrastructure Blockchains

Overview

While Bitcoin started the crypto revolution, it was Ethereum and other infrastructure blockchains that expanded its possibilities. This module unpacks how blockchains like Ethereum power decentralised applications (dApps), enable smart contracts, and provide the scalable infrastructure needed for Web3 to thrive.

Content

From Bitcoin to Ethereum – Understand why Ethereum was created to go beyond simple payments and enable programmable blockchain solutions.
Smart Contracts & dApps – Learn how smart contracts automate transactions and how dApps are reshaping industries like finance, gaming, and identity.
ETH, Gas & Transactions – Explore how Ethereum’s gas system works, and how fees affect usability, scalability, and network congestion.
Comparing Infrastructure Chains – Discover how Ethereum, Solana, Avalanche, and others differ in speed, scalability, and adoption.

Who’s It For

Beginner to intermediate learners looking to understand how the crypto ecosystem extends beyond Bitcoin. Ideal for developers, entrepreneurs, investors, and tech-curious individuals exploring how blockchain infrastructure supports real-world applications.

Why It Matters

Ethereum and other Layer 1 blockchains are the foundation for everything from NFTs and DeFi to tokenised real-world assets. As more of the internet becomes decentralised, understanding these infrastructure layers is essential for navigating the future of Web3. This module shows you where the real innovation is happening and why it’s shaping the next digital era.
