 # Waku - Idea Board
 
-- Chat app : P2P messaging app that uses wallet addresses/ENS domains as user IDs and facilitates chat between users.
-- Poll app : App for users to create or participate in polls that require users to connect their wallet.
-- Customer support chat bubbles : A web widget that can be embedded in any website to facilitate messaging between a customer and a customer support agent.
-- Community chat : Chats that are gated to specific communities that own a specific NFT/Token/Onchain proof.
-- Authentication methods : New methods to authenticate a user while using a dapp. For example : connect your wallet by scanning a QR code that holds a URI on Waku.
+
+- Polling/Voting: Enable polling or voting off-chain, vote results could be aggregated and submitted on chain in one transaction.
+- Marketplace (buy/sell goods or NFTs, ride-share, etc): Send offer and negotiate off-chain. Highest bids sent over Waku could be binding and submitted to the contract by seller.
+- Collaborative editing: Use Waku for live collaborative editing of documents, saved version of documents can then be stored on decentralized storage.
+- Multiplayer games: Waku can be used to communicate game move off-chain, final state (e.g. winner) can then be submitted on chain for reward (e.g. NFT mint or winner takes stake).
+- IoT systems: Enable devices to communicate or report small data payload in a decentralized manner.
+- Decentralized wallet address ownership verification: Use Waku to enable communication between dApp and wallet such as signature or zeroknowledge proof exchange to prove identity.
+- Notifications centre: use an SDK (probably go-waku?) to build general Notification protocol over Waku and a mobile app allowing you to replace centralized Push Notifications provided by Apple/Google
+- API generator: build a tool to generate a Waku protocol (and code) from a provided OpenAPI specification 
 - Leader Election Protocol: Leader election can viewed as a soft consensus mechanism. Implement something like [RAFT](https://raft.github.io/) as a library on top of Waku (using any SDK), so that users can easily plug it in their applications

+- Chat app: Proper chat protocol is complex, we recommend to instead wait for our upcoming Chat SDK.
