Fast Geth Sync

Geth P2P Sync Feature

We're excited to introduce a new feature in this release: The Geth P2P Sync Feature. This feature significantly enhances the speed of block data synchronization by leveraging peer-to-peer syncing among geth nodes, as opposed to the previous method of deriving transactions from L1 for each synchronization.

Benefits of Geth P2P Sync Feature​

The Geth P2P Sync Feature greatly accelerates block data synchronization. Our tests on the testnet have shown impressive results:

  • In full mode, the sync time has been reduced from the previous 7 days to approximately 15 hours.
  • In snap mode, syncing can be accomplished in about 1 hour.

These improvements can save considerable time and resources, thus improving the overall performance of your operations.

Configurations for Geth P2P Sync Feature​

New Configurations (op-node)​

  • l2.engine-sync=true
  • l2.skip-sync-start-check = true

The above settings are essential for enabling the Geth P2P Sync Feature. Please ensure that these settings are correctly configured in your op-node.

Existing Configurations (op-geth)​

  • syncmode=snap/full
  • bootnodes=${bootnode_addr}

You can select either of the two options for the syncmode:

  1. full (Recommended): This mode performs a full sync and executes each block. The sync time has been significantly reduced with the new Geth P2P Sync Feature, taking about 15 hours on the testnet (latest height: 10 million).
  2. snap: This mode performs a snapshot sync, which does not execute transactions but still maintains data completeness. This mode is recommended when your P2P peer nodes are trustworthy. The sync time is about 1 hour on the testnet.

For the bootnodes configuration, you can use the following geth bootnode nodes:
