+::: note
 
-For private, permissioned blockchain networks, Besu uses the same synchronization modes as public networks, but with specific configurations for private network needs.
+We recommend Snap sync because it follows the Ethereum specification and enables you to serve full historical data, making you a valuable network peer.
 
-When setting up a private network, consider the following:
-
-- Use the same sync modes as public networks (snap, checkpoint, fast, or full sync).
-- Configure the network with a custom genesis file.
-- Set the network ID and bootnode(s) specific to your private network.
-- Implement permissioning features to control network access.
+:::
 
-Choose the appropriate sync mode based on your private network's requirements and node purposes.
+| Sync Mode | Description | Requirements | Method | Limitations |
+|-----------|-------------|--------------|--------|-------------|
+| Snap synchronization | Recommended for fastest sync and lowest storage requirements on Mainnet.| Besu version 22.4.0 or later | Downloads as many leaves of the trie as possible, reconstructs the trie locally. Snap is faster than Fast sync. | Cannot switch from fast sync to snap sync mid-process. |
+| Checkpoint synchronization | Efficient sync from a specific checkpoint block configured in the genesis file. | Besu version 22.4.3 or later | Syncs from a checkpoint block defined in the genesis file. Is the fast sync and has the lowest storage requirements. | Not supported for QBFT or IBFT 2.0 networks without a checkpoint configuration. |
+| Fast synchronization | Default for named networks except the dev development network. | None | Downloads block headers and transaction receipts, verifies chain from genesis block. | Might become impossible to sync Ethereum mainnet in the future; not supported with private transactions. |
+| Full synchronization | Downloads and verifies the entire blockchain and state from the genesis block. This builds an archive node, with full state history.| None | Downloads entire blockchain, verifies all states from genesis block. | Slowest sync mode, requires the most disk space. |
 
 :::note
-When configuring syncing for a private network, ensure all nodes use compatible sync modes and configurations.
+
+Ethereum nodes sync two types of data: chain data (blocks) and world state data. Snap and Checkpoint syncs handle chain data like Fast sync does. 
+They differ in how they process world state data.

 ## Run an archive node
 
 An archive node stores all historical states of the blockchain.
