What's State Sync?

The Tendermint Core 0.34 release includes support for state sync, which allows a new node to join a network by fetching a snapshot of the application state at a recent height instead of fetching and replaying all historical blocks. This can reduce the time needed to sync with the network from days to minutes. Click here for more infomation.

Starting New Node From State Sync

1. Install Binary (Version: )
We need to install the binary first and make sure that the version is the one currently in use on mainnet.

2. Enable State Sync
We can configure Tendermint to use state sync in $DAEMON_HOME/config/config.toml.

3. Start the daemon:
If you are resetting node, run unsafe-reset-all or tendermint unsafe-reset-all --home ~/.HOME before you start the daemon.

Enable Snapshot For State Sync

To make state sync works, we can enable snapshot in $DAEMON_HOME/config/app.toml
