WhiZper represents the future of social media, prioritizing privacy and freedom of expression, and offering a truly anonymous platform for users worldwide to create secret communities and speak freely. 🥷🏻

Users of WhiZper can anonymously create a group, join a group and send messages. The system is protected by mobile biometrics authentication and zero knowledge proofs.

• 📄 contracts: WhiZper smart contracts. It extends @iden3/contracts EmbeddedZKPVerifier to verify on-chain proofs and control creating group and sending messages.
• 🎯 lib: WhiZper flutter code. It implements the Privado ID protocol and the UI of the mobile app.
  • ios: Specific settings in iOS system.
  • android Sepcific settings in Android system.
• 🧩 subgraph: WhiZper's onchain subgraph.

1. Run flutter pub get from example directory.
2. Configure the environment with the following .env, or copy env.sample and fill your the keys.
3. Run build_runner to generate .g.dart files:

   dart run build_runner build --delete-conflicting-outputs

flutter run

and choose the device (now it only works for iOS device and Android)

1. Privado.iD: Privado ID protocol is used to verify the users' credentials.
2. Scaling technologies: WhiZper wants to bring privacy to the whole EVM ecosystems. We deployed WhiZper smart contract on many Layer2 or EVM-compatible chains to scale the ZKPs. See contracts for more deployments.
3. The Graph: The Graph is used to store and query on-chain data. See subgraph for the deployments.

• Customize users credentials: Group creators can decide the users who join the group should have which data. For example: more than 20 years old, joined some hackathon event before.
• Encrypt messages: Now the messages are not encrypted, but it can be done by Privado credentials very easily. See example schemas.
• Improve infrastructures: Now the main resources are host by iden3 and Polygon, but the Privado ID is EVM compatible. There should be more decentralized issuers and verifiers.
• Improve UI/UX: Support more functions in a chat app, support better UX, smooth onchain experience.
