Optimism - OP Mainnet Bedrock Upgrade – Maintenance details

Much of our our core OP Mainnet infra is back online! Continue to track https://oplabs.notion.site/External-OP-Mainnet-Bedrock-Upgrade-Infra-Status-Tracker-07d7c9c0916243b8b743b74af77d37f9?pvs=4 for updates on other key infrastructure in the OP Mainnet ecosystem.

The Bridge UI has been unpaused. Deposits and Withdrawals can now be executed on OP Mainnet from: https://app.optimism.io/bridge/

The public endpoint is back live: https://mainnet.optimism.io/

This should unblock most wallets to begin working again.

For Archival node operators: While we recommend using the legacy-geth archival datadir we upload once it's ready, given the size of the archival data disk and the time it'll take for it to become available (up to 24 hours), we recommend preserving your legacy archival nodes and routing archival traffic to them if possible. To check if your legacy archival node is able to serve traffic, please do the following:
Verify that the head block number is 105235062
Verify that the head block hash is 0x21a168dfa5e727926063a28ba16fd5ee84c814e847c81a699c7a0ea551e4ca50
If both of these criteria are true, then your legacy archival node is on the same block as the archival datadir and can be used to serve user traffic.

You can set --rollup.historicalrpc <l2geth-rpc> on op-geth and it will forward requests for historical data it can't handle to l2geth.

For node operators:
We have received reports that the full node Bedrock datadir is taking a long time to download. Since it is available on GCS, you can use parallel downloader tools like aria2 to make it faster. This method has seen download speeds in excess of 100MB/s. Some recommendations:

• Run the download on a high-network box in the cloud.
• Use aria2 or the gcloud storage cp command to download the file in parallel.

The Bedrock sequencer has started up.

Images, and data directories for node operators can be found here. Key external OP Mainnet infrastructure is starting to come back online. View the OP Mainnet Infra Tracker to follow along.

L1 smart contract upgrades have been successfully implemented. The portal has been unpaused, and deposits/withdrawals have been re-enabled.

The migrated (Bedrock) datadir required to spin up op-geth has been successfully hosted and is now ready for distribution.

Full Node Operators are now fully unblocked to spin up.
Archival Node Operators will need to wait for the archival datadir, which may take an additional 5-10 hours.

The datadir can be downloaded from the link found in the OP Mainnet docs: https://community.optimism.io/docs/useful-tools/networks/#links

Node Operators: Docker images are now available in our community hub docs.
op-node version: https://github.com/ethereum-optimism/optimism/releases/tag/op-node%2Fv1.1.0 (Docker Images are in the release notes)

op-geth version: https://github.com/ethereum-optimism/op-geth/releases/tag/v1.101105.2 (Docker Images are in the release notes)
Please await the upload of the Migrated Datadir before you can fully spin up your OP Mainnet Bedrock nodes.

We are now starting to execute the L2 portion of the migration. This is the longest step in the migration process, and could take up to 1.5 hours. During this phase of the migration, ETH balances and withdrawals will be migrated. Successful completion of this stage will conclude the L2 portion of the migration, and we will perform all related checks before moving on to subsequent phases.

The migration has started. Legacy network deposits and withdrawals have been paused.

Transaction acceptance on the legacy sequencer has been halted.
