Finally, instruct the isomorphic tool to load the checkpoint:
isomorphic-tool apply-checkpoint --path $DATA_DIR/checkpoint.json --height 1234567
Success Output: You should see:

Manual downloads are fine for one-off setups, but production validators need automation. Here is a cron script that will download Isomorphic Tool Checkpoint weekly and roll back if corruption is detected.
#!/bin/bash
# save as /usr/local/bin/auto_checkpoint.sh
LOG_FILE="/var/log/isomorphic_checkpoint.log"
DATA_DIR="/var/lib/isomorphic/data"
LATEST_HEIGHT=$(curl -s https://checkpoints.isomorphic.org/mainnet/latest_height.txt) Finally, instruct the isomorphic tool to load the
echo "$(date): Starting checkpoint download for height $LATEST_HEIGHT" >> $LOG_FILE
Use wget with resume capability (vital for large files): Success Output: You should see:
wget -c --progress=bar:force https://checkpoints.isomorphic.org/mainnet/checkpoint_1234567.tar.zst -O $DATA_DIR/checkpoint.tar.zst
