Aptos vs Flow

Aptos is a Layer‑1 written in Rust that uses the Move language and AptosBFT v4—a Diem‑derived HotStuff variant—to finalise blocks in less than 1 second. Its Block‑STM executor runs transactions in parallel and abort‑reexecutes on conflict, achieving > 100k TPS in public benchmarks. The 2024 ‘Quorum Store’ upgrade optimised mempool sharding and reduced latency under network partition.

Flow features a multi‑role architecture—collection, consensus, execution and verification nodes—that splits tasks for high throughput while keeping deterministic execution. Cadence, its resource‑oriented language, powers popular NFT projects like NBA Top Shot and Gaia marketplace. The 2024 ‘Spork’ upgrade introduced FCL walletless onboarding and bridged USDC from Ethereum to boost DeFi liquidity.
