+
+This is an informational spec that show cases the concept of adaptive nodes.
+
+# Node types - a continuum
+
+We can look at node types as a continuum, from more restricted to less restricted, fewer resources to more resources.
+
+![Node types - a continuum](../../../../rfcs/30/adaptive_node_continuum2.png)
+
+## Possible limitations
+
+- Connectivity: Not publicly connectable vs static IP and DNS
+- Connectivity: Mostly offline to mostly online to always online
+- Resources: Storage, CPU, Memory, Bandwidth
+
+## Accessibility and motivation
+
+Some examples:
+
+- Opening browser window: costs nothing, but contribute nothing
+- Desktop: download, leave in background, contribute somewhat
+- Cluster: expensive, upkeep, but can contribute a lot
+
+These are also illustrative, so a node in a browser in certain environment might contribute similarly to Desktop.
+
+## Adaptive nodes
+
+We call these nodes *adaptive nodes* to highlights different modes of contributing, such as:
+
+- Only leeching from the network
+- Relaying messages for one or more topics
+- Providing services for lighter nodes such as lightpush and filter
+- Storing historical messages to various degrees
+- Ensuring relay network can't be spammed with RLN
+
+## Planned incentives
+
+Incentives to run a node is currently planned around:
+
+- SWAP for accounting and settlement of services provided
+- RLN RELAY for spam protection
+- Other incentivization schemes are likely to follow and is an area of active research
+
+# Node protocol selection
+
+Each node can choose which protocols to support, depending on its resources and goals.
+
+![Protocol selection](../../../../rfcs/30/adaptive_node_protocol_selection2.png)
+
+In the case of protocols like 11/WAKU2-RELAY etc (12, 13, 19, 21) these correspond to Libp2p protocols.
+
+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.
+
+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.
+
+# Waku network visualization
+
+We can better visualize the network with some illustrative examples.
+
+## Topology and topics
+
+The first one shows an example topology with different PubSub topics for the relay protocol.

+
+## Legend
+
+![Waku Network visualization legend](../../../../rfcs/30/adaptive_node_network_topology_protocols_legend.png)
+
+The dotted box shows what content topics (application-specific) a node is interested in.
+
+A node that is purely providing a service to the network might not care.
+
+In this example, we see support for toy chat, a topic in Waku v1 (Status chat), WalletConnect, and SuperRare community.
+
+## Auxiliary network
+
+This is a separate component with its own topology.
+
+Behavior and interaction with other protocols specified in Vac RFCs, e.g. 25/LIBP2P-DNS-DISCOVERY, 15/WAKU-BRIDGE, etc.
+
+## Node Cross Section
+
+This one shows a cross-section of nodes in different dimensions and shows how the connections look different for different protocols.
