Private Messaging Without Metadata
Z-TEXT is a zk-SNARKs blockchain messenger built on BitcoinZ. No phone number. No email. No SIM.
Most apps protect what you say. Z-TEXT is built to expose less of who you talk to, and when — the metadata surveillance actually wants.
Don't trust the pitch. Check the proof.
❓ What is metadata?
Metadata is everything about your message except the words. Who you talked to. When. How often. From where. Most apps encrypt the message but leak all of this.
❓ Why does metadata matter?
Because metadata reveals your life. Encrypted content hides what you said. Metadata still shows who, when, and how often — enough to map your contacts, habits, and movements. Surveillance wants the metadata, not the words.
❓ How does Z-TEXT reduce metadata?
Z-TEXT needs no phone number, no email, no SIM. Your Z-TEXT identity is a 24-word seed phrase. Z-TEXT messages are shielded with zk-SNARKs zero-knowledge proofs and AES-256-GCM encryption on the BitcoinZ blockchain — built to expose as little as possible about who talks to whom.

❓ Do I need a phone number?
No. Z-TEXT is built to work without one.
❓ Can I trust this?
Don't guess — check. Z-TEXT publishes its threat model and funds an on-chain bug bounty. Review the proof, not the pitch.
