What Is Z-TEXT? The Number-Free Blockchain Messenger
Security Announcement
🔒 Z-TEXT Just Became the Most Secure Messenger on Earth
Four layers of protection. Zero servers. Nobody else has this combination.
Most messaging apps protect your content. But they still know who you are, who you talk to, and when. That data gets logged, stored, and handed to authorities on request.
Z-TEXT doesn't work that way. No central message server sees who talks to whom. And now, with our latest update, we've added a fourth layer of protection that makes Z-TEXT the only messenger in the world with this complete security stack.
The 4-Layer Z-TEXT Security Stack
| 🛡️ |
Layer 1 — zk-SNARKs On-Chain Shield Every message is wrapped in a BitcoinZ Sapling shielded transaction. Your name, your contact's name, the content — all hidden on the blockchain. zk-SNARKs hide who talked to whom on the blockchain. |
| 🔐 |
Layer 2 — X25519 + Ed25519 End-to-End Encryption The message body itself is encrypted with battle-tested IETF standards, audited by security researchers worldwide for over a decade. The same tech trusted by global security professionals. |
| 🚫 |
Layer 3 — Zero Servers. Zero Accounts. Zero Data. Messages travel device-to-device through shielded transactions. You hold your seed, your keys, your messages. There’s no phone number or message log to hand over. Nothing to breach. No company holding your data. |
| ⚛️ |
Layer 4 — ML-KEM-768 Post-Quantum Encryption ✅ LIVE NOW The newest NIST FIPS 203 standard, protecting your messages against future quantum computers. Already active in Z-TEXT today — not a roadmap promise. |

Score based on: metadata shielding · E2E encryption · decentralized architecture · post-quantum · no identity required
The bottom line: Signal has post-quantum encryption but runs on central servers — so your metadata can still be logged and subpoenaed. WhatsApp and iMessage are the same story. Only Z-TEXT combines all four layers with zero servers. That combination is, as far as we know, unique in the world.
