The Web3 Ecosystem
Four pillars of the decentralized internet
dApps
Decentralized apps: runs on smart contracts, no single company controls it
Examples: Uniswap, Aave, OpenSea
NFTs
Unique digital tokens proving ownership: art, tickets, identities
Examples: CryptoPunks, Bored Apes, ENS
DAOs
Organizations governed by smart contracts and token-holder votes
Examples: MakerDAO, Uniswap DAO, Nouns
DeFi
Decentralized finance: lending, trading without banks, 24/7
Examples: Aave, Compound, Curve
