Node Upgrade v3.9.3 & AnyTrust Migration

Upgraded the Plume node to Offchain Labs v3.9.3. This critical update migrates our Data Availability layer from Celestia to AnyTrust DA and introduces support for ArbOS 51 and the Ethereum Fusaka upgrade.

Migration Checklist

• Update Docker Image Switch to: offchainlabs/nitro-node:v3.9.3-8bc5554

• Remove Old Flags: Delete the following flags from your node configuration:

--node.da-provider.enable
--node.da-provider.rpc.url
--node.da-provider.with-writer
--node.data-availability.enable

• Add New Flags: Add the following flags (replace URLs for testnet if necessary):

--node.data-availability.enable=true
--node.data-availability.parent-chain-node-url=<YOUR L1 RPC>
--node.data-availability.rest-aggregator.urls=http://das-plume-mainnet-1.t.conduit.xyz

• Delete Legacy Resources: Remove celestia-das-server, daprovider, and any other Celestia-related containers.

• Restore Snapshot: If your node is out of sync, download the latest snapshot

Full node setup and config available at How to Run a Node

Note: To avoid breaking changes while migrating to the Fusaka upgrade, properly syncing all historical blob data is essential. Ensure your node is using an updated Beacon RPC that retains all historical blob data. This guarantees that your Nitro node can sync from periods beyond the standard blob retention limit. For more details on Beacon node historical data, please refer to the documentation: https://docs.arbitrum.io/run-arbitrum-node/beacon-nodes-historical-blobs
