+# Optimism Rollup
+
+Optimism is Ethereum's Layer 2 solution, leveraging Optimistic Rollups to enhance transaction speeds and lower costs. It conducts transactions off-chain, reconciling final states on the main Ethereum chain, all while preserving compatibility with Ethereum smart contracts.

+
+## Setting Up an Optimism Node
+
+Optimism stands out as the inaugural choice in the Rollups suite. Initiating an Optimism node on Dappnode parallels the familiar Stakers Menu, yet with some distinctions:
+
+- Utilize an `op-node` client to link with the Optimism Mainnet.
+- Employ `op-geth` or the forthcoming `op-erigon` client to bridge your `op-node` to Ethereum's execution layer, echoing the beacon chain/consensus client's role on the mainnet.
+- For archive nodes, `op-legacy` is essential for transactions predating the Bedrock upgrade.
+- A connection to an Ethereum Mainnet node is required. If your Dappnode already operates one, the Rollups menu will streamline configuration. Otherwise, integrate a public RPC for Ethereum Mainnet connection.
+
+For a deeper dive, consult Optimism’s documentation:
+
+- [OP Geth docs](https://op-geth.optimism.io/)
+
+- [OP Node Operator](https://community.optimism.io/docs/developers/bedrock/node-operator-guide/)

+# Ethereum Rollups: An Overview
+
+Rollups are advanced layer-2 scaling solutions designed to increase the throughput of the Ethereum network. By executing and storing transaction data off the main Ethereum chain while keeping a cryptographic commitment on-chain, Rollups enhance scalability and reduce fees. Rollups can be broadly categorized into two types: Optimistic Rollups and zk-Rollups, each with its unique approach and trade-offs.
+
+Currently, we support:

+
+## Enable rollups
+
+To enable this feature, you need to switch on the rollups module in the top bar of the Dappnode UI (Dappmanager):
