Communication in the present day is heavily influenced by third-party intervention, ranging from censorship and de-platforming to intermediaries that seek to profit from rent and the misuse of data in the surveillance economy.
Waku is intended to empower individuals by returning control of communication to them. It is the go-to standard for Web3 communication, offering a **scalable decentralized communication** solution.
| **Scalability** | Whisper doesn't scale very well, specifically when it comes to bandwidth usage on mobile devices. | Uses sharding to partition the network into separate gossipsub networks, while maintaining a shared discovery network for peer location. |
| **Spam Resistance** | Proof of work requires too much battery and compute power making it a poor mechanism for heterogeneous nodes. | Uses innovative p2p economic spam protection mechanism RLN Relay. |
| **Incentivization Infrastructure** | There is no incentive to run a Whisper node. | Research in progress to design incentivization for node operators. |
| **Formal Specification/Documentation** | Lack of formal and unambiguous specification. | The specs and docs are open-source and licensed under CC0, making them freely available for anyone to read, modify and improve without restrictions. |
| **Portability** | Runs over devp2p which limits where Whisper can run and how. | Waku is built using libp2p, making it easy to run Waku anywhere. |
