Blockchain Basics

What you'll learn

Blockchain Basics does what its title promises and not much more, which is actually its strength: it works through the core mechanics — transactions, wallets, consensus, and scalability — without wandering into hype or speculation. It's built for people who need to understand how the technology functions, not just what it's disrupting.

Who it's for

Developers and working web3 professionals are the intended audience, which means it assumes you can handle technical concepts even if you've never touched a blockchain codebase before. It's a sensible starting point before specializing further into Solidity, smart contracts, or a specific chain's tooling.

Why grab it

Consensus mechanisms and scalability trade-offs are the parts of blockchain that most explainer content glosses over in favor of price talk — this course puts them front and center instead, which is exactly what you want if you're planning to build rather than just speculate.
