Waku is the decentralized communication protocol and network built for the Ethereum ecosystem. Thanks to js-waku, you can leverage the Waku network and add censorship-resistant communications to your dApp. Waku can be used to enable human-to-human communications such as chat groups and encrypted private messages. It can also be used for machine-to-machine use cases, such as multi-sig signature aggregation, layer-2 coordination or game communication layer.
