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 op-erigon 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.
