Blockchain Basics
Start here. What a blockchain actually is, who owns what, and why any of it is hard — no prior technical background needed.
7 lessons
A plain-language introduction to blockchain technology. By the end you will understand shared ledgers, how blocks are chained by hashes, what a wallet really holds, how a network agrees on one history without a central authority, and why almost everything now runs on layer 2 rather than directly on Ethereum.
