Arbitrum vs Scroll
Arbitrum leads on 2 of 2 shared benchmarks, Scroll on 0. Arbitrum wins on Fastest L2 block time, live across Robinhood, Arbitrum, Base and 7 more (259 ms vs 2.80 s), Fastest LayerZero source chain by end-to-end message delivery (31.71 s vs 3.5 min).
Arbitrum
Optimistic rollup built on Nitro stack with a fast-finality sequencer. Sub-second block times (~250 ms) via a 250 ms default block interval, far below the 2 s OP Stack convention. 7-day fraud-proof window for L1 finality.
Scroll
Native bytecode-equivalent zkEVM rollup. Sequencer cadence is prover-bound: empty periods see longer gaps between blocks while busy minutes produce blocks at a sub-3-second rate.
