Follow these steps to sync your node from the latest snapshot.
Install Dependencies
Install lz4 and aria2 for decompression and fast downloads.
sudo apt-get update && sudo apt-get install -y lz4 aria2
Download Snapshot
Use aria2c for a faster multi-connection download. Replace the URL with the one shown above.
Download with aria2c
aria2c -x 16 -s 16 -k 1M https://snapshot.kalia.network/snapshots/casper/casper-test-8332460.tar.gz -o snapshot.tar.lz4
Stop Node & Back Up Keys
Stop the node before applying the snapshot. Always back up priv_validator_state.json to prevent double-signing.
Stop node
sudo systemctl stop casperd-test
Back up validator state
cp $HOME/.casper-test/data/priv_validator_state.json $HOME/priv_validator_state.json.bak
Reset Node Data
Clear existing chain data. Your address book is preserved.
casperd tendermint unsafe-reset-all --home $HOME/.casper-test --keep-addr-book
Decompress & Apply Snapshot
Stream-decompress the snapshot directly into the node data directory.
lz4 -c -d snapshot.tar.lz4 | tar -x -C $HOME/.casper-test
Restore Validator State
Restore priv_validator_state.json to prevent double-signing after restart.
cp $HOME/priv_validator_state.json.bak $HOME/.casper-test/data/priv_validator_state.json
Restart Node & Verify
Start the node and confirm it is catching up from the snapshot block height.
Start node
sudo systemctl start casperd-test

journalctl -u casperd-test -f --no-hostname -o cat
