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)
|
||
|
|
