# Celestia Mocha-4 snapshot

Bootstrap a Celestia `mocha-4` testnet node in \~5 minutes instead of a multi-hour full sync.

<iframe src="https://snapshots.unitynodes.com/celestia-mocha/widget.html" width="100%" height="110" style={{ border: 'none', background: 'transparent', display: 'block' }} />

## What's inside

* `data/` folder from a live `celestia-appd v9.0.4-mocha` node running on **PebbleDB** with aggressive pruning (`custom` / `keep-recent=100` / `interval=19`, `indexer=null`).
* `snapshots/` sub-dir included so your node can immediately serve state-sync to peers.

**Download:** [snapshots.unitynodes.com/celestia-mocha/latest.tar.lz4](https://snapshots.unitynodes.com/celestia-mocha/latest.tar.lz4) - refreshed every 4 hours.
