MEV & Interoperability: Rollups, Cross-L2 & Cross-chain
summary
Panel lays out concrete cross‑domain mechanics and tradeoffs: Cosmos IBC runs in production with tens of thousands of IBC packets/day and supports failure recovery, Celestia offers a shared data‑availability/timestamping layer but does not enforce cross‑domain semantics, Starkware now powers three production systems (dYdX, Immutable X and a soon‑to‑launch NFT product), optimistic rollups use a two‑level messaging with atomicity while Arbitrum pairs an inbox with a sequencer that can reorder, and MEV inevitably shifts between layers (the “conservation of MEV”) rather than disappearing.
