 <h3 id="channels-relay-mediated-groups" tabindex="-1">Channels: relay-mediated groups</h3>
 <p>Channels are groups where message delivery is mediated by dedicated relay members rather than by direct connections between all members. Channels extend the group sub-protocol with additional roles (<code>relay</code>, <code>observer</code>), message signing for administrative actions, a binary batch format for signed and forwarded messages, and an asynchronous delivery pipeline.</p>
 <p>For architecture and design rationale, see <a href="/docs/protocol/channels-overview.html">SimpleX Channels Overview</a>. For protocol-level detail - wire formats, message types, signing mechanics, delivery pipeline - see <a href="/docs/protocol/channels-protocol.html">SimpleX Channels Protocol</a>.</p>
