Lesson 2: Digital Money & Assets – Cryptocurrencies, Tokens & Wallets gives you practical knowledge about digital value and, most importantly, how to keep it secure.

You will master the critical distinction between native cryptocurrencies (coins like Ether that are built into the blockchain and required for transaction fees) and programmable tokens (assets like stablecoins and NFTs created by smart contracts). You will explore the double-spending problem—how blockchain prevents the same digital currency from being spent twice—and dive into public and private keys, understanding that your public address can be shared freely while your private key or seed phrase must never be revealed to anyone.

You will learn how transaction signing proves ownership without exposing your secret, and compare hot wallets (convenient but vulnerable) against cold wallets (secure but less convenient) to make informed security choices. Through a key pair simulation and a wallet safety role play, you will complete a reflection journal titled "Securing My Assets," outlining a personal three-step security plan and explaining the distinction between an Ethereum native coin and an ERC-20 token.
