Transports help move data packets across a network by establishing connections between peers. They define the rules and protocols to ensure efficient network transmission, routing, and data delivery.

Waku is a transport-agnostic framework that allows developers to choose and support multiple protocols according to their requirements. For Waku nodes, the following transports are recommended:

  • TCP: By default, Waku nodes use TCP for communication. Service nodes should employ TCP for listening to and connecting with other nodes.
  • Secure WebSocket: In browser environments, secure WebSocket is used. Service nodes are encouraged to set up SSL certificates to enable incoming connections from browsers and serve them securely.
  • Other protocols like WebRTC, WebTransport, and QUIC have been researched and studied for potential integration.

Waku ensures compatibility and improved communication capabilities by following these recommended transports.
