Sync/Snapshot Options

Option 1: Sync Using Snapshot (Cumulo)

Snapshot Update Steps

1. Stop the Node:

   sudo systemctl stop axone

2. Backup Validator State:

   [ -f $HOME/.axoned/data/priv_validator_state.json ] && cp $HOME/.axoned/data/priv_validator_state.json $HOME/.axoned/priv_validator_state.json.backup

3. Remove Old Data:

   rm -rf $HOME/.axoned/data

4. Download & Extract Snapshot:

   curl -L https://snap.cumulo.pro/axone/axoned.tar.lz4 | lz4 -d | tar -xf - -C $HOME/.axoned

5. Restore Validator State (if backed up):

   [ -f $HOME/.axoned/priv_validator_state.json.backup ] && mv $HOME/.axoned/priv_validator_state.json.backup $HOME/.axoned/data/priv_validator_state.json

6. Restart the Node:

   sudo systemctl restart axone

7. Monitor Logs:

   sudo journalctl -u axone -f --no-pager

---

Option 2: State Sync

1. Stop the Node:

   sudo systemctl stop axone

2. Reset the Node:

   axoned tendermint unsafe-reset-all --home $HOME/.axoned

3. Configure State Sync:

   • Set RPC server:

     SNAP_RPC="https://rpc-axone-mainnet.onenov.xyz:443"

   • Get block height and hash:

     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)

   • Update config.toml:

     sed -i \
       -e "s|^enable *=.*|enable = true|" \
       -e "s|^rpc_servers *=.*|rpc_servers = \"$SNAP_RPC,$SNAP_RPC\"|" \
       -e "s|^trust_height *=.*|trust_height = $BLOCK_HEIGHT|" \
       -e "s|^trust_hash *=.*|trust_hash = \"$TRUST_HASH\"|" \
       $HOME/.axoned/config/config.toml

4. Restart the Node:

   sudo systemctl restart axone

5. Monitor Logs:

   sudo journalctl -u axone -f -o cat

6. Check Sync Status:

   axoned status | jq .SyncInfo
