Intro to Flow
summary
Flow advertises itself as a layer‑1 that scales without sharding or mandatory L2s, using distinct execution vs consensus nodes to push heavy compute to beefy machines; NBA Top Shot runs show hundreds of thousands of users handled on‑chain. Cadence enforces a Cadence resource model where NFTs live in accounts and cannot be copied, contracts can be updated, and wallets support walletless onboarding (Dapper, Blocto, Lilico) and hybrid custody. Tooling includes play.flow.com, the flow CLI and a VS Code Cadence extension; stats cited: 20M+ accounts, 360M+ transactions, and examples like 4.5M free POAP‑style mints.
