About This Course
Bitcoin & The Blockchain takes you beneath the surface of the world's first and largest digital asset. We break down the technical layers in plain English: how distributed ledgers maintain agreement across thousands of global nodes without trusting a bank.
You will learn about cryptographic hashing (SHA-256), mining puzzle constraints, wallet custody safety, and the Lightning Network's layered scaling model which bridges the gap between digital gold and digital cash.
