Building in Web3: Real-world use cases that actually make sense
summary
Defines web3 by the actual primitives: public smart‑contract chains, native tokens, and standards like ERC‑721/1155; argues those matter when parties don’t fully trust each other and need a credibly neutral global ledger. Gives concrete builds: Parallax, Beam and Sling Money use USDC stablecoins to offer virtual USD accounts with near‑zero fees and faster settlement than Wise/PayPal; Friend.tech launches a tokenized social market as a no‑wallet progressive web app; Nike Dot Swoosh and Reddit collectible avatars let creators mint interoperable NFTs and gate communities while earning fees.
