Openbands is a privacy‑first social app for verified employees. Connect a wallet, sign in with your work email, and generate a zero‑knowledge proof that reveals only your email domain (e.g., openbands.xyz). Your identity never leaves your device; posts and comments are anonymous.
Live app: https://app.openbands.xyz
- Verified anonymity via ZK proofs (domain‑only disclosure)
- Wallet connect (EVM) and on‑chain proof recording
- Company‑first feeds (New / Hot)
- Anonymous posts and comments
- Search by company domain
- Connect EVM wallet
- Sign in with Google (work email)
- Client generates a ZK proof – only the email domain becomes public
- Public inputs (domain, nullifier, wallet) are recorded on‑chain
- Post/comment anonymously; domain is displayed, identity is not
Google may be able to probabilistically de-anonymize users:
-
If someone sends a message right after registering, Google could attempt a timing attack by matching the OAuth completion time with the message activity.
-
If only a small number of users from a given domain are using the app, Google could narrow down the sender by linking activity back to those few accounts.
