💾 Snapshots

PostHuman Snapshots:

• 📍 Mainnet: https://snapshots.posthuman.digital/celestia-mainnet/
• 📍 Testnet: https://snapshots.posthuman.digital/celestia-testnet/
• ⏱️ Mainnet and testnet snapshots are automated every 4 hours
• 🌐 Fast worldwide via Cloudflare R2

Manual snapshot restore:

export CELESTIA_HOME="$HOME/.celestia-app"
export SERVICE_NAME="celestia-appd-testnet"
export SNAP_DIR="$HOME/celestia-testnet-snapshot-restore"

rm -rf "${SNAP_DIR}"
mkdir -p "${SNAP_DIR}"
curl -fL https://snapshots.posthuman.digital/celestia-testnet/snapshot-latest.tar.lz4 | \
  lz4 -dc | tar -xf - -C "${SNAP_DIR}"
test -d "${SNAP_DIR}/data/application.db"

if [ -f "${CELESTIA_HOME}/data/priv_validator_state.json" ]; then
  cp "${CELESTIA_HOME}/data/priv_validator_state.json" "${CELESTIA_HOME}/priv_validator_state.json.backup"
fi

sudo systemctl stop "${SERVICE_NAME}"
BACKUP_DIR="${CELESTIA_HOME}/data.before-snapshot-$(date +%Y%m%d-%H%M%S)"
if [ -d "${CELESTIA_HOME}/data" ]; then
  mv "${CELESTIA_HOME}/data" "${BACKUP_DIR}"
fi
mv "${SNAP_DIR}/data" "${CELESTIA_HOME}/data"
sed -i -e 's|^db_backend *=.*|db_backend = "pebbledb"|' "${CELESTIA_HOME}/config/config.toml"
if grep -q '^app-db-backend' "${CELESTIA_HOME}/config/app.toml"; then
  sed -i 's|^app-db-backend *=.*|app-db-backend = "pebbledb"|' "${CELESTIA_HOME}/config/app.toml"
else
  printf '\napp-db-backend = "pebbledb"\n' >> "${CELESTIA_HOME}/config/app.toml"
fi
if [ -f "${CELESTIA_HOME}/priv_validator_state.json.backup" ]; then
  mv "${CELESTIA_HOME}/priv_validator_state.json.backup" "${CELESTIA_HOME}/data/priv_validator_state.json"
fi
sudo systemctl start "${SERVICE_NAME}" && sudo journalctl -u "${SERVICE_NAME}" -f

🆕 New Features

Network Selection

Supports both Mainnet and Testnet:

export NETWORK_TYPE=testnet  # or mainnet (default)
./celestia-manager.sh

Custom Installation Directory

Install to custom location (e.g., separate disk):

export CELESTIA_HOME=/mnt/data/.celestia-app
./celestia-manager.sh

Script now checks disk space of selected directory, not just root filesystem.

DA Nodes Management

Complete suite for Data Availability nodes:

• Main Menu → Option 5 (Data Availability Nodes)
• Option 1 → Install DA Node (submenu for all DA types)
• Support for Bridge, Full Storage, and Light nodes
• Unified management interface

---

🔄 Quick Update

./celestia-manager.sh
# Select: 2 (Update Node) → Press Enter for latest version

---

🛡️ Security Best Practices

• 🔐 Backup ~/.celestia-app/config/priv_validator_key.json
• 🔥 Use script's firewall configuration (Option 3 → 5)
• 🔑 Enable SSH key-based authentication
• 👁️ Setup monitoring and alerts
• 💰 Never share private keys or seed phrases

---

🐛 Troubleshooting

Node not syncing?

sudo journalctl -u celestia-appd -f -n 100
celestia-appd status 2>&1 | jq .SyncInfo

Service won't start?

sudo systemctl status celestia-appd
sudo journalctl -u celestia-appd -n 50 --no-pager

Check sync status:

./celestia-manager.sh
# Select: 7 (Status & Logs) → 2 (Check Sync Status)
