Sequencer batches are how Robinhood Chain (an Arbitrum Nitro L2) commits its transaction data to Ethereum L1. Each batch bundles a contiguous range of L2 blocks and posts them — as EIP-4844 blobs — in a single L1 transaction, giving those L2 blocks Ethereum-grade data availability and, once final, Ethereum-grade finality.
