Understanding Crypto
The essential guide to mastering blockchain fundamentals and navigating the Web3 ecosystem.
What is a blockchain?
A digital ledger shared across thousands of computers. Every transaction is recorded permanently.
Cryptocurrencies
Digital units of value: fuel (ETH), store of value (BTC) or stability (USDT).
Wallets
Your gateway into Web3. A public address to receive, a private key to protect.
CEX vs DEX
Centralised exchanges (Binance) or decentralised (Uniswap), two ways to swap your crypto.
Layer 1 vs Layer 2
The base blockchain vs the highways built on top to make things faster and cheaper.
Gas and fees
Why every transaction has a cost, and how to lower your fees on the blockchain.
The order book
The order book reflects market activity in real time: bids, asks, market price.
Liquidity
How easily an asset can be traded without affecting its price.
