# State sync

In order to use this feature, you will have to edit a couple of things inside your `~/.realionetwork/config/config.toml` file, under the `statesync` section:

1. Enable state sync by setting `enable=true`
2. Set the RPC addresses from where to get the snapshots using the `rpc_servers` field:
   * See Peer & Seeds information in order to get RPC addresses in our [discord group](https://discord.gg/Nv9EUbRnKb)
3. Get a trusted chain height, and the associated block hash. To do this, you will have to:
   * Get the current chain height by running:

     <pre class="language-bash" data-full-width="false"><code class="lang-bash">curl -s &#x3C;rpc-endpoint>/commit | jq "{height: .result.signed_header.header.height}"
     </code></pre>
   * Once you have the current chain height, get a height that is a little lower (200 blocks) than the current one.\
     To do this you can execute:

     <pre class="language-bash" data-full-width="false"><code class="lang-bash">curl -s &#x3C;rpc-endpoint>/commit?height=&#x3C;your-height> | jq "{height: .result.signed_header.header.height, hash: .result.signed_header.commit.block_id.hash}"

     # Example
     # curl -s &#x3C;rpc-endpoint>/commit?height=100000 | jq "{height: .result.signed_header.header.height, hash: .result.signed_header.commit.block_id.hash}"
     </code></pre>
   * Now that you have a trusted height and block hash, use those values as the `trust_height` and `trust_hash` values. Also, make sure they're the right values for the Realio Network version you're starting to synchronize:

     | **State sync height range** | **RealioNetwork version** |
     | --------------------------- | ------------------------- |
     | `0 - 1235764`               | `v1.0.2`                  |
   * Here is an EXAMPLE (no not copy!) of what the `statesync` section of your `~/.realionetwork/config/config.toml` file should look like in the end (the `trust_height` and `trust_hash` should contain your values instead):

     ```
       enable = true

       rpc_servers = "0.0.0.0:26657"
       trust_height = 100
       trust_hash = "E8ED7A890A64986246EEB02D7D8C4A6D497E3B60C0CAFDDE30F2EE385204C314"
       trust_period = "336h0m0s"
     ```
4. Add peers to `~/.realionetwork/config/config.toml` file:

TIP\
Our discord group is a great source for getting peer information from the community. After joining the [Discord Group](https://discord.gg/Nv9EUbRnKb), look for the #testnet-seeds-peers channel or the #mainnet-seeds-peers channel and ask the current members for one if needed.
{% endhint %}

Add these seeds here to the `~/.realionetwork/config/config.toml` file

```
seeds = "....." 
peers = "....."
```
