The doc is outdated.

As a new user of the Optimism platform, I found that I can’t launch the devnet following the tutorial.

So, I checked the latest Optimism package changes.

  • Updates YAML configuration format from a list-based to a map-based structure
  • Adds more detailed node configuration with explicit EL and CL layer specifications
  • Includes reference link to the upstream repository for additional details

Tip: Customize your code reviews with copilot-instructions.md. Create the file or learn how to get started.

📝 Walkthrough

Walkthrough

Replaces the optimism_package.chains YAML example in pages/operators/chain-operators/tutorials/chain-dev-net.mdx from a list-based, inline-participants schema to a map keyed by chain name. The new example defines a single chain (rollup-1) with explicit node entries (node0, node1) and per-node nested el and cl configuration including explicit type fields. The previous network_params block (name, network_id) is removed and the chain key is used as the identifier. Added comments document the hierarchical mapping and node/EL/CL flags.
