As soon as the rollup posts transaction data on the data availability layer, rollup nodes can compute the new state root of the rollup and finality is achieved within the realm of the rollup.

Imagine a town where construction (transactions) is happening rapidly, and there's a local council (optimistic rollup) that must approve all the building plans (transaction data). The council's clerk (sequencer) gathers all the plans and submits them to the public noticeboard (DA layer) for everyone to

Devs on Linea and L2s

hey builders, started a /linea focused channel for inputs or feedback

"Sequencers on L2s, in addition to largely being centralized entities, also operate similarly to both an L1 builder and an L1 proposer–they both build the blocks with transactions from users and searchers and propose blocks to their underlying layers"

Restaking in Shared Sequencers

The sequencer that gains most market share will save Ethereum from fragmentation and close the gap on interoperability

Operation of a rollup consists of 4 parts: Ordering, Execution, Proposing and Proving

Flow for asset transfers between a rollup and the Ethereum chain using a bridge contract

L2 Flow

Users -> Transactions -> Sequencer -> Blocks -> Block Headers -> Bridge Contract on Ethereum Main Chain -> Light Clients and Full Nodes -> Fraud/Validity Proofs

Ethereum

How do people feel about "strong L2" vs "light L2" as umbrella terms for things with unconditional security (rollups, plasma, channels) vs things with partial security (validiums, pre-confirmations...) that's still better than a multisig?

"The sequencing of such rollups—based sequencing—is maximally simple and inherits L1 liveness and decentralisation"
