Restore from Snapshot

WARNING: Stop the node before restoring. If you are running a validator, back up priv_validator_state.json FIRST.

1Install zstd

Decompression utility for .tar.zst files.

sudo apt install zstd -y

2Stop the node

sudo systemctl stop atomoned

3Back up validator state (validators only)

cp $HOME/.atomone/config/priv_validator_state.json $HOME/priv_validator_state.json.bak

4Download the snapshot

wget -O atomone-snapshot.tar.zst https://snapshots.apollo-validator.eu/atomone/snapshots/latest.tar.zst

5Restore from snapshot

rm -rf $HOME/.atomone/data/application.db $HOME/.atomone/data/state.db $HOME/.atomone/data/evidence.db
tar -I zstd -xf atomone-snapshot.tar.zst -C $HOME/.atomone/data/

6Restore validator state (validators only)

cat $HOME/priv_validator_state.json.bak > $HOME/.atomone/config/priv_validator_state.json

7Start the node

sudo systemctl start atomoned

8Verify and clean up

sudo systemctl status atomoned
rm -v atomone-snapshot.tar.zst

Snapshot Files

Old snapshots are automatically deleted. Only the latest 2 snapshots are kept.

ls -lh $HOME/.atomone/data/snapshots/

Snapshots are created every 6 hours without stopping the node. The script archives application.db, state.db, and evidence.db.

State Sync allows your node to sync by downloading a recent state snapshot from peers, without replaying all historical blocks. This is typically faster than block-by-block sync.

State Sync Setup

1Get trust parameters

Get the latest block height and hash from our RPC:

# Get latest height
HEIGHT=$(curl -s https://rpc.atomone.apollo-validator.eu/status | jq -r '.result.sync_info.latest_block_height')
echo "Height: $HEIGHT"

# Get block hash
HASH=$(curl -s "https://rpc.atomone.apollo-validator.eu/block?height=$HEIGHT" | jq -r '.result.block.header.app_hash')
echo "Hash: $HASH"

2Configure state sync in config.toml

Edit $HOME/.atomone/config/config.toml:

[state-sync]
rpc_servers = "https://rpc.atomone.apollo-validator.eu"
trust_height = <YOUR_HEIGHT>
trust_hash = "<YOUR_HASH>"
enable = true
trust_period = "168h"

3Set persistent peers

# Get peers from our list
PEERS=$(curl -s https://snapshots.apollo-validator.eu/atomone/peers.md | grep -oP '[a-f0-9]+@[0-9.]+:26656' | tr '\n' ',' | sed 's/,$//')

# Set in config.toml
sed -i "s/^persistent_peers = .*/persistent_peers = \"$PEERS\"/" $HOME/.atomone/config/config.toml

4Start the node

atomoned start

The node will sync via state sync protocol automatically.

5Verify sync

# Check sync status
curl -s https://rpc.atomone.apollo-validator.eu/status | jq '.result.sync_info'

# When synced, "catching_up" will be false

Troubleshooting

"state sync failed"

Verify trust_height is not too old (within trust_period). Verify trust_hash matches the block at trust_height.

"could not discover peers"

Add more persistent_peers. Check firewall allows port 26656.

Sync is slow

Add more RPC servers to rpc_servers (comma-separated). Ensure good network connectivity.

Alternative: If state sync doesn't work, you can use snapshot restore instead.

API

curl -s https://snapshots.apollo-validator.eu/api/atomone/snapshots/latest | jq

Returns JSON with height, size, and download URL.
