Waku is a decentralized communication network that supports person-to-person and machine-to-machine communication, enabling secure and private operation without a central authority.
The following is a list of some of the use cases that have been considered and their current status.
### Chat Messenger
Waku can be used as the communication layer when building a private, decentralized, and censorship-resistant messenger.
Waku can be used to take NFT bids and offers off-chain, enabling gas savings. Additionally, it allows for adding a social media layer, enabling NFT owners to like, comment, and perform other social actions.
Waku can enable two parties to set up and maintain a state channel.
### Voting and Proposals
To save on gas fees, votes for proposals submitted on the blockchain can be exchanged over Waku. These votes can then be aggregated and submitted to the blockchain to commit the result.
### Signature Exchange for Multi-Signature Wallets
Waku can enable multiple owners of a given multi-signature wallet to exchange signatures in a decentralized, private, and censorship-resistant manner, allowing for the approval of transactions.
### Game Mechanics Communication
Waku can be used as the communication layer for a peer-to-peer, decentralized game, eliminating the need for a centralized infrastructure for gameplay communications.
dApp operators can use communication between a user's wallet and their dApp to notify users (e.g., governance token holders can be notified to vote on a proposal) or to request transaction signatures from the wallet.
While chat messengers are a type of social media that can be decentralized and made censorship-resistant through Waku, other forms of social media, such as news feeds, blog posts, and audio or video sharing, can also benefit from using Waku.
