# Run a Smart Vault Node

## Connecting to the Test Network

You will initialize and connect your node to the Lightstreams test blockchain network called Sirius. The nodes use the blockchain network for deploying and controlling smart contracts. 

**Smart Vault uses smart contracts for managing files access permissions.**

### Initialize the node

```bash
leth init --nodeid=1 --network=sirius --lightclient=true --blockchain_url=https://rpc.sirius.lightstreams.io --federation=false --demo=true
```

### Start the node

```bash
leth run --nodeid=1 --network=sirius --https

### Stopping the node

You can stop a node at any time by pressing **Ctrl+C**

## OPTIONAL: Create a Second Node

Smart Vault is all about peer-to-peer content sharing. If you are interested in Smart Vault, sooner or later you will want to share a file between two nodes. To have two Smart Vault nodes running locally on the same computer to test the peer-to-peer behaviour of sharing files then run the following commands:

### Initialize the node

In a new command window, start the second node:

```javascript
leth init --nodeid=2 --network=sirius --lightclient=true --blockchain_url=https://rpc.sirius.lightstreams.io
```

### Start the node

Run the secord node:

```bash
leth run --nodeid=2 --network=sirius --https
```
