❗ Ecotone Sepolia Upgrade

This is a mandatory release for node operators on the Sepolia Superchain. The Ecotone protocol upgrade will activate on Wed Feb 21 17:00:00 UTC 2024 on Sepolia OP Chains.

New Beacon Endpoint

It is required for Sepolia operators to configure a Beacon endpoint for op-node, because soon after the Ecotone activation, batch transactions will be sent as 4844 blobs, and blobs can only be retrieved from Beacon nodes. If you're using Lighthouse, make sure to use at least the finalized version v4.6.0 because the latest rc contains a bug in its blob_sidecars http endpoint.

The op-node provides a new configuration flag & env var for configuring the Beacon endpoint: --l1.beacon and $OP_NODE_L1_BEACON

Mainnet node operators are strongly encouraged to already get their Beacon node infra set up so that they will be ready to enable their Beacon endpoints once Ecotone activates on Sepolia and Mainnet. Activation dates for these networks will be communicated at a later date.

✨ Features

The upstream op-geth dependency is updated to v1.101308.0, which is based on upstream geth v1.13.8. This implies a change of the underlying logging framework to slog (https://github.com/ethereum-optimism/optimism/pull/8917).

🐞 Bug Fixes

This release now adheres to the spec and lets op-node call the correctly-versioned methods on the EL client (https://github.com/ethereum-optimism/optimism/pull/9253).

Receipts are now validated before entering the cache, fixing a bug that required restarts of op-node that got stuck during synching (https://github.com/ethereum-optimism/optimism/pull/9417).
