Every "private" messenger still asks for one thing that gives you away: a phone number, an email, or some other identity anchor.
Z-TEXT doesn't. It's a zk-SNARKs blockchain messenger built on BitcoinZ — combining a shielded messenger, a password manager, a crypto wallet, and Channels broadcasting, all under a single 24-word seed phrase.
The core idea
Instead of routing messages through a company's servers, Z-TEXT broadcasts them as shielded transactions on the BitcoinZ blockchain. zk-SNARKs zero-knowledge proofs hide sender, recipient, and content — not just encrypted in transit, but cryptographically invisible on-chain.
No phone number. No email. No SIM. Zero metadata by architecture, not by policy.
What's actually in the app
- Shielded messenger — end-to-end encrypted, zk-SNARKs + AES-256-GCM
- Password manager — on-chain, encrypted locally before it ever touches the blockchain
- Crypto wallet — BitcoinZ, shielded (Z) and transparent (T) addresses
- Channels — broadcast to unlimited subscribers for one flat 0.0002 BTCZ fee, same cost whether 1 person reads it or 500,000
