# Use Cases

Waku is a generalized communication network.
It can enable numerous use cases, both person-to-person (e.g. messenger) and machine-to-machine (e.g. state channels).

This is a non-exhaustive list of use cases that we have considered and their current status.

If we are aware of other projects using js-waku and other use cases that could be implemented,
feel free to open a [PR](https://github.com/vacp2p/docs.wakuconnect.dev).

Legend:

- _Live_: We are aware of projects who have implemented this use case.
- _SDK Available_: An SDK is available to easily implement this use case.
- _Work In Progress_: We are aware of projects working to implement this use case.
- _Proof of Concept_: A Proof of concept was created, sometimes as part of a hackathon.
- _Idea_: This is an unexplored use case, more research and work may be needed.

## Chat Messenger

| _Work In Progress_ |
| ------------------ |

<--->

## Voting and Proposals

| _SDK Available_ |
| --------------- |

For proposals submitted on the blockchain,
exchange votes over Waku to save gas.
Votes can then be aggregated and submitted to the blockchain to commit the result.

## Signature Exchange for Multi-Sig Wallets

| _Idea_ |
| ------ |

Use Waku to enable several owners of a given multi-sig wallets to exchange signatures in a decentralized,
private & censorship-resistant manner to approve transactions.

## Gameplay Communication

| _Proof of Concept_ |
| ------------------ |

Use Waku as the communication layer for a peer-to-peer, decentralize game.
Remove the need of a centralized infrastructure for gameplay communications.

- [Super Card Game](https://github.com/fjij/ethonline-2021)

<--->

## dApp to Wallet Communication

| _Live_ |
| ------ |

Communication between a user's wallet and a dApp can be used by dApp operators to notify users
(e.g. governance token holders get notified to vote on a proposal),
or for a dApp to request transaction signature to the wallet.

- [WalletConnect 2.0](https://walletconnect.com/)
- [HashPack](https://www.hashpack.app/hashconnect)

<--->

## Layer 2 Communication

| _Idea_ |
| ------ |

Use Waku as an existing communication network to broadcast and aggregate layer 2 transactions.
Possibly increasing privacy, anonymity and resilience.

## Generalized Marketplace

| _Proof of Concept_ |
| ------------------ |

Use Waku to enable users to offer, bid, accept and trade goods and services
to create a ride-sharing or tradings apps.

<--->

## Social Media Platform

| _Idea_ |
| ------ |

[Chat Messenger](#chat-messenger) is one form of social media that can be empowered by Waku to be decentralized
and censorship-resistant.
Other form of social media: news feed, blog posts, audio or video sharing, can also benefit of Waku.
