:::tip Use Warp sync for faster syncing

By default, the node performs `full` sync, which downloads and validates the full blockchain
history. `warp` sync can be used as a faster way to sync the validator node.

`./target/production/polkadot --sync warp`

Warp sync initially downloads and validates the finality proofs from [GRANDPA](../learn/learn-consensus.md#finality-gadget-grandpa)
and then downloads the state of the latest finalized block. After the warp sync, the node is ready to
import the latest blocks from the network and can be used as a Validator. The blocks from genesis
will be downloaded in the background. Check
[this discussion](https://substrate.stackexchange.com/questions/334/what-kinds-of-sync-mechanisms-does-substrate-implement/)
for more information about the different sync options available.

:::note Validators should sync using the RocksDb backend

This is implicit by default, but can be explicit by passing the `--database RocksDb` flag.
