Polled every 60 seconds, 2 pages per poll (cursor via `nextToken`).","Latency definition: `destination.tx.blockTimestamp - source.tx.blockTimestamp` from a LayerZero message row with `status.name: DELIVERED`. Both timestamps are Unix seconds from the source and destination chain blocks respectively.","Filter: only `DELIVERED` messages contribute to latency. In-flight statuses (INFLIGHT, CONFIRMING, PAYLOAD_STORED, BLOCKED, FAILED) are counted separately in `lz_message_status_total` so a spike in CONFIRMING without matching DELIVERED surfaces a stuck-message incident.","Dedupe: last 10 000 guids kept in memory (rolling FIFO). LayerZero sustained rate is ~4 messages/second network-wide, so the cache holds ~40 minutes of history.","Bucketing: histogram with buckets 2, 5, 10, 15, 20, 30, 45, 60, 90, 120, 180, 300, 600, 900, 1200, 1800 seconds (30 min ceiling).","Guard: samples with delta `< 0` or `> 30 min` are dropped (clock skew, stuck messages re-executed later).","No canary transactions: this bench observes organic LayerZero traffic (~250 messages/hour network-wide). No wallet is funded, no gas is paid.","Scope: LayerZero-supported source chains with mainnet traffic in the observation window. LayerZero exposes many exotic chains (orderly, flare, ape, robinhood) that show up as separate rows once volume is non-trivial; low-traffic sources will have wide error bars.","Fair-comparison caveat: LayerZero DVNs sign pre-finality by default, so end-to-end delivery excludes the source-chain finality wait that finality-aware networks (Chainlink CCIP, Axelar on Ethereum-source) impose. Comparing raw numbers to those on ETH-source lanes is not apples-to-apples."],"license":"CC-BY-4.0"}
