Every database you've ever used has an admin. Someone who can edit records, reverse transactions, freeze accounts, or shut the whole thing down. Usually that's fine. Sometimes it's the problem.
Blockchains are databases without admins. Nobody can change the rules, nobody can freeze your account, nobody can reverse your transaction. The tradeoff is that nobody can help you either. Send money to the wrong address? Gone. Lose your password? Gone forever.
This course teaches you how blockchains actually work. Not the idealistic version where everything is decentralized and free. The real version, where you pay for every computation, where your transactions are visible to everyone, and where sophisticated actors are competing to extract value from you.
You'll learn what you're actually paying for when you pay gas. Why prices move against you when you trade. What MEV is and why it matters. And how to think about the tradeoffs between convenience and control.
