Blockchain Basics

Yes, but the hands-on work is guided rather than project-heavy. You'll use a virtual machine image to set up an Ethereum environment, build a test chain, create and unlock accounts, mine, and send Ether, along with block-inspection exercises and quizzes. That practice helps you connect ideas like transactions and consensus to the way a blockchain actually behaves.

The course focuses on how blockchain systems are structured, how Bitcoin and Ethereum handle transactions and blocks, and how decentralized networks establish trust. You'll also study the security pieces behind them, especially hashing and public-key cryptography, along with Ethereum's account model and gas. Overall, it gives you a working picture of how blockchain protocols operate and why they remain reliable without a central authority.

You should be able to explain how a blockchain validates transactions, links blocks, and maintains trust across a decentralized network. You'll also be able to inspect basic Bitcoin and Ethereum data and carry out simple Ethereum operations, such as creating an account, sending Ether, and checking balances on a test chain. That's a practical scope for one course: understanding the mechanics clearly and completing simple transactions yourself.

It's more concept-first than hands-on. The course spends more time explaining how Bitcoin and Ethereum work, then uses guided exercises to reinforce that through tasks like setting up a test chain and sending transactions. If you want an open-ended build course, this one will feel more introductory.
