How does it work?

The backbone of Waku Network is the Waku Relay protocol. It is a pubsub protocol based on libp2p gossipsub. Other Waku protocols have been defined to enable capabilities such as:

1. retrieving historical messages for mostly-offline devices
2. key turn solution for encrypted communication (symmetric encryption, ECIES/asymmetric encryption, noise handshake).
3. preserving bandwidth usage for resource-restricted devices
4. Economic spam protection (rate limit) with privacy preserving capabilities
5. Mass deanonymization protection (research in progress)
