# Rollup
|
|
|
|
This directory contains the three essential rollup services for the Scroll chain:
|
|
- Event Watcher (<a href="./cmd/event_watcher/">event_watcher</a>): watches the events emitted from the L1 and L2 contracts and updates the event database.
|
|
- Gas Oracle (<a href="./cmd/gas_oracle/">gas_oracle</a>): monitors the L1 and L2 gas price and sends transactions to update the gas price oracle contracts on L1 and L2.
|
|
- Rollup Relayer (<a href="./cmd/rollup_relayer/">rollup_relayer</a>): consists of three components: chunk and batch proposer and a relayer.
|
|
- The chunk and batch proposer proposes new chunks and batches that sends Commit Transactions for data availability and Finalize Transactions for proof verification and state finalization.
