Rome's based sequencer is called Nexus. In Nexus, the L1 (Ethereum) proposer includes rollup blocks built by Solana (builder) using the Rome stack.
Delivers atomic composability between Solana, Ethereum, and other ecosystems.
Ensures fast, fair, and decentralized transaction sequencing for Rome L2s.
Enhances the developer and end-user experience by offering pre-confirmations.
"A rollup is said to be based, or L1-sequenced, when its sequencing is driven by the base L1. More concretely, a based rollup is one where the next L1 proposer may, in collaboration with L1 searchers and builders, permissionlessly include the next rollup block as part of the next L1 block. The sequencing of such rollups—based sequencing—is maximally simple and inherits L1 liveness and decentralisation."
