<p>The <code>portal_bridge</code> will connect to Fluffy node over the JSON-RPC
interface and start gossiping an <code>LightClientBootstrap</code> for

<p>Next, it will gossip a new <code>LightClientOptimisticUpdate</code>,
<code>LightClientFinalityUpdate</code> and <code>LightClientUpdate</code> as they become available.</p>
