State Sync

State Sync is a module built into the Cosmos SDK to allow validators to rapidly join the network by syncing your node with a snapshot enabled RPC from a trusted block height.

💡 Tip: State sync is much faster than downloading a snapshot and is recommended for quickly joining the network.

Stop the service and reset the data

sudo systemctl stop lavad
cp $HOME/.lava network mainnet/data/priv_validator_state.json $HOME/.lava network mainnet/priv_validator_state.json.backup
lavad tendermint unsafe-reset-all --home $HOME/.lava network mainnet

Configure the state sync

STATE_SYNC_RPC="https://rpc-lava.winnode.xyz"
STATE_SYNC_PEER=PEER_NODE_ID_HERE@rpc-lava.winnode.xyz:26656
LATEST_HEIGHT=$(curl -s $STATE_SYNC_RPC/block | jq -r .result.block.header.height)
SYNC_BLOCK_HEIGHT=$(($LATEST_HEIGHT - 1000))
SYNC_BLOCK_HASH=$(curl -s "$STATE_SYNC_RPC/block?height=$SYNC_BLOCK_HEIGHT" | jq -r .result.block_id.hash)

sed -i \\
  -e "s|^enable *=.*|enable = true|" \\

Restart the service and check the log

sudo systemctl restart lavad && sudo journalctl -u lavad -f
