Proposes grouping cross-chain messages into a single batch commit on the source chain and delivering that batch to the destination, then applying a deterministic but hard-to-predict reorder (e.g. shuffle by block hash) before execution so searchers face a proof-of-work for searchers style cost to find profitable orderings. Claims this is easy to implement with low on‑chain overhead, adds latency, reduces insertion/reordering MEV but is a mitigation not a fix and fails if many messages touch the same state or when strict ordering is required.
