OP Mainnet vs Polygon

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.

Polygon PoS combines Plasma checkpoints with a Proof‑of‑Stake validator set, supplying low‑fee EVM smart contracts. The Polygon 2.0 roadmap introduces Aggregation Layer and.zk‑powered chains (CDK) that will share a unified POL staking token. Partnerships with Starbucks Odyssey and DraftKings underline its consumer‑brand strategy.
