How Do Decentralized Perpetual Futures Exchanges Address Front-Running without Commit-Reveal?

Many perpetual futures DEXs use an off-chain order book with on-chain settlement. Orders are matched quickly and privately off-chain by a centralized relayer or sequencer, hiding them from the public mempool and eliminating MEV front-running based on transaction order.

They also use oracle-based pricing and sometimes batching to ensure fair execution. This sacrifices full decentralization of the matching process for speed and MEV resistance.
