# Quick Start

The testnet has a base currency of ETH, as well as a token called HIVE. HIVE is used for payments and collateralization.

## Prerequisites

* A private key and funds for the testnet
  * See the instructions in [Quick Start](/user-guide/clients/quick-start.md) to set up MetaMask and use the faucet to receive initial funds
* Linux (latest Ubuntu LTS recommended)
* Docker
* Nvidia GPU
* Nvidia drivers
* Nvidia docker drivers

### Install Bacalhau

```
cd /tmp
wget https://github.com/bacalhau-project/bacalhau/releases/download/v1.0.3/bacalhau_v1.0.3_linux_amd64.tar.gz
tar xfv bacalhau_v1.0.3_linux_amd64.tar.gz
sudo mv bacalhau /usr/bin/bacalhau
sudo mkdir -p /app/data/ipfs
sudo chown -R $USER /app/data
```

### Install CoopHive

```
curl -sSL -o hive https://github.com/CoopHive/hive/releases/download/v0.1.12/hive-linux-amd64
chmod +x hive
sudo mv hive /usr/bin/
```

### Write .env file

Create a .env file for your node. `/app/coophive/resource-provider-gpu.env` should contain:

```bash
WEB3_PRIVATE_KEY=<your private key>
```

Caution: do not use the same key for both client and compute node, even for testing.

### Install systemd unit for Bacalhau

Open `/etc/systemd/system/bacalhau.service` and paste the following:

```
[Unit]
Description=CoopHive v0
After=network-online.target
Wants=network-online.target systemd-networkd-wait-online.service

[Service]
Environment="LOG_TYPE=json"
Environment="LOG_LEVEL=debug"
Environment="HOME=/app/coophive"
Environment="BACALHAU_SERVE_IPFS_PATH=/app/data/ipfs"
Restart=always
RestartSec=5s
ExecStart=/usr/bin/bacalhau serve --node-type compute,requester --peer none --private-internal-ipfs=false

[Install]
WantedBy=multi-user.target
```

### Install systemd unit for GPU provider

Open `/etc/systemd/system/coophive-resource-provider.service` and paste the following:

```
[Unit]
Description=CoopHive v0 Resource Provider GPU
After=network-online.target
Wants=network-online.target systemd-networkd-wait-online.service

[Service]
Environment="LOG_TYPE=json"
Environment="LOG_LEVEL=debug"
Environment="HOME=/app/coophive"
Environment="OFFER_GPU=1"
EnvironmentFile=/app/coophive/resource-provider-gpu.env
Restart=always
RestartSec=5s
ExecStart=/usr/bin/coophive resource-provider

[Install]
WantedBy=multi-user.target
```

Reload `systemd`'s units/daemons. This needs to be repeated if the `systemd` files above are modified.

```
sudo systemctl daemon-reload
```

Start `systemd` units:

```
sudo systemctl start bacalhau
sudo systemctl start coophive-resource-provider
```

Use `systemctl` to check the status, and debug with `journalctl` if needed. For example,&#x20;

`sudo journalctl -uf coophive-resource-provider`&#x20;

will stream the output from your CoopHive node. Records of the resource provider accepting jobs can be found in the logs.

## Security

### Allowlisting Modules

Set the environment variable `OFFER_MODULES` in the GPU provider to a comma separated list of module names of allowed modules.
