Celestia Testnet Snapshot

Network: Mocha-4 pruned consensus node
DB backend: PebbleDB
Cadence: every 4 hours via POSTHUMAN snapshot automation
Download: https://snapshots.posthuman.digital/celestia-testnet/snapshot-latest.tar.lz4

Up-to-date height, build time, size, and snapshot file name are published at snapshot.json alongside the snapshot file.

Snapshot Endpoint

• Index: https://snapshots.posthuman.digital/celestia-testnet/
• Metadata: https://snapshots.posthuman.digital/celestia-testnet/snapshot.json
• Snapshot file: https://snapshots.posthuman.digital/celestia-testnet/snapshot-latest.tar.lz4
• Genesis: https://snapshots.posthuman.digital/celestia-testnet/genesis.json
• Addrbook: https://snapshots.posthuman.digital/celestia-testnet/addrbook.json

Preflight

Always compare snapshot metadata with the live RPC before using the archive:

curl -fsS https://snapshots.posthuman.digital/celestia-testnet/snapshot.json | jq .
curl -fsS https://rpc-celestia-testnet.posthuman.digital/status | \
  jq '.result.node_info.network, .result.sync_info.latest_block_height, .result.sync_info.catching_up'

Stop and investigate before restoring if:

• chain_id is not mocha-4.
• RPC is catching up or the RPC height is behind snapshot metadata.
• The snapshot file is unexpectedly small or unavailable.
• You cannot preserve validator keys and priv_validator_state.json.

Quick restore

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

# Download and validate before stopping the node.
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

For validator recovery, preserving and restoring priv_validator_state.json is mandatory. Never replace it with an older value from a snapshot.

The pipeline keeps the PebbleDB snapshot pruned and ready for rapid validator or full-node recovery. Browse the current build at https://snapshots.posthuman.digital/celestia-testnet/.
