⛓️Sync

We take one node snapshot every day. We then delete all the previous snapshots to free up the space on the file server. The snapshot is designed for node opeartors to run an efficient node on Shentu

Download snapshot | Time: 00:00, 12:00 UTC | db: goleveldb | pruning: 100/0/50 | indexer: null

sudo systemctl stop shentud
cp $HOME/.shentud/data/priv_validator_state.json $HOME/.shentud/priv_validator_state.json.backup

State Sync

If you don't want to wait for a long synchronization you can use:

sudo systemctl stop shentud

cp $HOME/.shentud/data/priv_validator_state.json $HOME/.shentud/priv_validator_state.json.backup
shentud tendermint unsafe-reset-all --home $HOME/.shentud

peers="[email protected]:14656" 
SNAP_RPC="https://shentu-rpc.nodesphere.net:443"

sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" $HOME/.shentud/config/config.toml 

LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height);
BLOCK_HEIGHT=$((LATEST_HEIGHT - 2000));
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash) 

echo $LATEST_HEIGHT $BLOCK_HEIGHT $TRUST_HASH && sleep 2
