# Sunrise Data

[Sunrise Data](https://github.com/sunriselayer/sunrise-data) acts as a relay server connecting the L2 chain to the Sunrise DA layer.

## Sunrise Consensus Node

Requires a networked Sunrise node to operate. [Networks](/run-a-sunrise-node/networks.md) running Sunrise v0.3.0 or higher support Data Availability Layer.

Follow the [Node Guide](/run-a-sunrise-node/types/consensus.md) on how to create a consensus node.

### How to set up sunrise-data

1. Running `sunrised` See [Consensus Node](https://github.com/SunriseLayer/gitbook/blob/main/build/node/types/consensus/full-consensus-node.md) for setting up.
2. Clone sunrise-data repo

   ```bash
   cd ~
   git clone https://github.com/sunriselayer/sunrise-data.git
   cd sunrise-data
   make install
   ```
3. Create and edit `config.toml`

   ```bash
   cp config.default.toml config.toml
   nano config.toml
   ```

   To connect to a local IPFS daemon, leave the `ipfs_api_url` field empty

   Change `home_path` to your .sunrise directory and `publisher_account` to your sunrised key's name

   ```toml
   [api]
   port = 8000
   ipfs_api_url = ""
   ipfs_addrinfo = ""

   [chain]
   address_prefix="sunrise"
   home_path="/home/ubuntu/.sunrise"
   keyring_backend="test"
   sunrised_rpc="http://localhost:26657"

   [publish]
   publisher_account="your_publisher_account"
   publish_fees="10000uusdrise"

   [rollkit]
   port=7980
   data_shard_count=5
   parity_shard_count=5
   ```

   `home_path`, `keyring_backend`, `publisher_account` must be entered values on your sunrised keyring. See [Local Key Pair document](/run-a-sunrise-node/types/consensus/full-consensus-node.md#create-or-restore-a-local-key-pair) and set with `--keyring-backend test` option. For `home_path`, enter the path where the sunrise keyring exists. 　 For `sunrised_rpc`, it is preferable to run sunrised locally, but if this is not possible, use the published RPC. See our [Network Document](/run-a-sunrise-node/networks.md). A local key pair is still required in such cases.

   The other fields can be left as is.

### Run IPFS on local

1. Run IPFS

   ```bash
   wget https://dist.ipfs.tech/kubo/v0.31.0/kubo_v0.31.0_linux-amd64.tar.gz
   tar -xvzf kubo_v0.31.0_linux-amd64.tar.gz
   cd kubo
   sudo ./install.sh
   ipfs init --profile=lowpower
   ipfs daemon
   ```
2. Check the IPFS node ID and optionally share and add a remote peer

   ```bash
   ipfs id
   ```

### Start

```bash
sunrise-data rollkit
```
