</h2>
|

<ul>
|

<li>Connectivity: Not publicly connectable vs static IP and DNS</li>

Accessibility and motivation

<a class="anchor" href="#accessibility-and-motivation">#</a>
|
|
</h2>
|
|
<p>Some examples:</p>
|
|
<ul>
|
|
<li>Opening browser window: costs nothing, but contribute nothing</li>
|
|
<li>Desktop: download, leave in background, contribute somewhat</li>
|
|
<li>Cluster: expensive, upkeep, but can contribute a lot</li>
|
|
</ul>
|
|
<p>These are also illustrative, so a node in a browser in certain environment might contribute similarly to Desktop.</p>

Adaptive nodes
|
|
<a class="anchor" href="#adaptive-nodes">#</a>
|
|
</h2>
|
|
<p>We call these nodes <em>adaptive nodes</em> to highlights different modes of contributing, such as:</p>
|
|
<ul>
|
|
<li>Only leeching from the network</li>
|
|
<li>Relaying messages for one or more topics</li>
|
|
<li>Providing services for lighter nodes such as lightpush and filter</li>
|
|
<li>Storing historical messages to various degrees</li>
|
|
<li>Ensuring relay network can’t be spammed with RLN</li>
|
|
</ul>

|
|
Planned incentives
|
|
<a class="anchor" href="#planned-incentives">#</a>
|
|
</h2>
|
|
<p>Incentives to run a node is currently planned around:</p>
|
|
<ul>
|
|
<li>SWAP for accounting and settlement of services provided</li>
|
|
<li>RLN RELAY for spam protection</li>
|
|
<li>Other incentivization schemes are likely to follow and is an area of active research</li>
|
|
</ul>
|

<h1 id="node-protocol-selection">
|
|
Node protocol selection
|
|
<a class="anchor" href="#node-protocol-selection">#</a>
|
|
</h1>
|
|
<p>Each node can choose which protocols to support, depending on its resources and goals.</p>
|
|
<p><img src="../../../../rfcs/30/adaptive_node_protocol_selection2.png" alt="Protocol selection" /></p>
|
|
<p>In the case of protocols like 11/WAKU2-RELAY etc (12, 13, 19, 21) these correspond to Libp2p protocols.</p>
|
|
<p>However, other protocols like 16/WAKU2-RPC (local HTTP JSON-RPC), 25/LIBP2P-DNS-DISCOVERY, Discovery v5 (DevP2P) or interfacing with distributed storage, are running on different network stacks.</p>
|
|
<p>This is in addition to protocols that specify payloads, such as 14/WAKU2-MESSAGE, 26/WAKU2-PAYLOAD, or application specific ones. As well as specs that act more as recommendations, such as 23/WAKU2-TOPICS or 27/WAKU2-PEERS.</p>

<p>The first one shows an example topology with different PubSub topics for the relay protocol.</p>

<p><img src="../../../../rfcs/30/adaptive_node_network_topology_protocols_legend.png" alt="Waku Network visualization legend" /></p>
|
|
<p>The dotted box shows what content topics (application-specific) a node is interested in.</p>
|
|
<p>A node that is purely providing a service to the network might not care.</p>
|
|
<p>In this example, we see support for toy chat, a topic in Waku v1 (Status chat), WalletConnect, and SuperRare community.</p>
