Mantle vs Optimism
Mantle leads on 2 of 3 shared benchmarks, Optimism on 1. Mantle wins on Fastest L2 block time, live across Robinhood, Arbitrum, Base and 7 more (1.78 s vs 1.93 s), Fastest LayerZero source chain by end-to-end message delivery (1.0 min vs 1.3 min). Optimism wins on Fastest Chainlink CCIP source chain by end-to-end delivery latency (18.8 min vs 20.0 min).
Mantle
Modular OP Stack fork using EigenDA for data availability rather than Ethereum calldata, cutting L1 anchoring cost. 2-second sequencer block time, MNT token for gas (ETH-pegged).
Optimism
Optimistic rollup and the canonical OP Stack reference implementation. 2-second sequencer block time, 7-day fraud-proof window, anchored to Ethereum L1 via batch submissions to the Optimism Portal.

Which is faster on fastest chainlink ccip source chain by end-to-end delivery latency, Mantle or Optimism?
On the Fastest Chainlink CCIP source chain by end-to-end delivery latency benchmark, Optimism leads at 18.8 min versus Mantle at 20.0 min. Live measurement is updated continuously by the OpenChainBench harness.
How is the Mantle vs Optimism comparison measured?
Every benchmark on this page uses the same open methodology, published at https://openchainbench.com/methodology. Data is CC-BY-4.0. Measurement harnesses are MIT-licensed.
How this pair was selected
A pair is published when all four conditions hold. Both providers run in the same OpenChainBench benchmark for at least seven consecutive days. Each provider has at least 1000 samples in the measurement window. The head to head query has observable third party search demand. Both providers have a public /products/[slug] page on OCB. The full pair ledger is versioned in the public repo so the methodology is externally verifiable.
