## Data Directory Structure

```

├── identity.key      # Node's cryptographic identity
├── peers.json        # Known peer addresses
├── dht/              # DHT records

## Identity Management

Your node's identity is stored in `identity.key`. This file contains:

* Ed25519 private key
* Node ID (derived from public key)

**Important:**

* Back up this file to maintain your identity
* If lost, you'll appear as a new node
* Never share this file with anyone
