Flow vs OP Mainnet

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.

OP Mainnet (Optimism) is an optimistic rollup that batches transactions to Ethereum and relies on fraud proofs submitted during a seven‑day challenge window. The Bedrock upgrade in 2023 cut L1 calldata costs by 40 % and introduced multi‑proof modularity. ‘RetroPGF’ rounds redistribute protocol revenue to public‑goods builders, governed by the OP token‑holder Collective.
