Download Isomorphic: Tool Checkpoint

Add to crontab for weekly execution:

wget -c --progress=bar:force https://checkpoints.isomorphic.org/mainnet/checkpoint_1234567.tar.zst -O $DATA_DIR/checkpoint.tar.zst Most isomorphic checkpoints are compressed using Zstandard (zst) for speed.

wget https://checkpoints.isomorphic.org/mainnet/SHA256SUMS.sig gpg --recv-keys [ISOMORPHIC_TEAM_KEY_ID] gpg --verify SHA256SUMS.sig SHA256SUMS After applying the checkpoint, run: download isomorphic tool checkpoint

| Error Message | Likely Cause | Solution | | :--- | :--- | :--- | | 404 Not Found | The checkpoint height is too old (pruned) | Use checkpoint list --limit 10 to find recent heights. | | Checksum mismatch | Corrupt download or man-in-the-middle | Delete the file and re-download using wget -c or curl -C - . | | Unsupported compression | Missing zstd library | Install: sudo apt install zstd -y | | Out of memory | RAM insufficient for checkpoint size | Increase swap space: sudo fallocate -l 8G /swapfile | | Application hash mismatch | Wrong network (mainnet vs testnet) | Re-download with --network testnet flag. | 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.
