# Using State Sync
Regen Mainnet and Redwood Testnet support State Sync (opens new window), which allows node operators to quickly spin up a node without downloading the existing chain data.
Although convenient, only a limited number of nodes should be spun up on the network using this method as these nodes will be unable to propagate historical data to other nodes.
Export a node moniker for the script to use:
Download and execute the state sync script:
