The Web3 Young Learners Encyclopedia is your guide to discovering the exciting world of cryptocurrency and blockchain. Whether you’re just getting started or already curious about Web3, this book is here to help you learn in a fun and easy way. This book isn’t here to teach you how to trade or invest. Instead, it’s designed to give you the knowledge you need to understand the digital world around you, ask the right questions, and be a responsible digital citizen. The following is a partial excerpt:
Altcoins
Altcoins are digital coins that are not Bitcoin.
Example: Ethereum (ETH), Litecoin (LTC), and Solana (SOL) are all altcoins.
HODL
“HODL” started as a typo of “HOLD,” but it became crypto slang for keeping your assets long-term. It’s now a symbol of belief in the future of crypto. However, remember that slang is not a strategy.
Example: People say “HODL!” during market crashes to stay positive.
Keys (Public & Private)
Crypto “keys” are like passwords. Your public key is used to receive assets, while your private key lets you control them.
Example: Public key = email address; Private key = your email password.
Proof Systems
Blockchains use “proof” systems to decide who can add new data. Proof of Work needs powerful computers and lots of energy. Proof of Stake relies on validators who lock up crypto to prove they’ll play fair.
Example: Bitcoin uses Proof of Work. Solana uses Proof of Stake.
Tokens (Not Toys!)
Tokens are digital items built on a blockchain. Some are used in games, some represent value, and others are just for fun. But remember, not every token has real-world worth.
Example: A game might reward players with tokens that only work inside that game.
Volatility Volatility (What It Means)
Volatility means the price of something goes up and down, sometimes very fast. It’s common in crypto. While it can be exciting, prices can change quickly and without warning.
Example: A coin that’s worth $10 today might increase or decrease significantly tomorrow.
