What is panic mode in Z-TEXT?

Panic mode in Z-TEXT means a second PIN called the Panic PIN. If you enter the Panic PIN instead of your real PIN, the app wipes itself instantly. No forensic trace remains. Your real data stays safe on the blockchain and is fully recoverable with your 24-word seed phrase on any clean device.

zk-SNARKs stands for Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge. It is a cryptographic method that proves a transaction happened without revealing who sent it, who received it, or what it contained. Z-TEXT uses zk-SNARKs to shield every message on the BitcoinZ blockchain.

Is Z-TEXT safe for journalists?

Yes. Z-TEXT stores no metadata, requires no phone number, and has no central server to subpoena. Panic mode wipes the app instantly if a device is seized. Stealth mode hides the app from view. Journalists and their sources are protected at every layer.

Honest Verdict

Threema is excellent — and we mean that sincerely. It has 12 million users, regular independent audits, open source code, Swiss legal protection, voice calls, group chats, and a fair price. For most people who want serious privacy, Threema is a mature, proven choice.

Z-TEXT is different — not just better in every way, but different by design. It eliminates the server entirely. No company sits between you and your contact. Messages travel on the BitcoinZ blockchain using zk-SNARKs shielding. Nobody can be subpoenaed because there is nothing to subpoena.

Z-TEXT is also honest about its limitations: currently in beta, no voice calls yet, costs more. If you need a messenger today with full features — Threema is your answer. If you want the next generation of private communication — Z-TEXT is worth the wait.
