Z-TEXT is the world's first zk-SNARKs shielded blockchain messenger. It combines a private messenger, a BitcoinZ crypto wallet, and a blockchain password manager in one app. No phone number, no server, no IP address required.

Does Z-TEXT require a phone number?

No. Z-TEXT requires no phone number, no email, and no personal information. Your identity is a cryptographic z-address on the BitcoinZ blockchain.

Is Z-TEXT quantum resistant?

Yes. Z-TEXT uses AES-256-GCM encryption and zk-SNARKs shielded addresses, reducing known quantum attack surfaces.

What is the price of Z-TEXT?

Z-TEXT Cyberpunk Presale License costs $128.52 as a one-time lifetime payment. It includes 15 billion possible messages and never expires.

How is Z-TEXT different from Signal or Telegram?

Unlike Signal or Telegram, Z-TEXT stores messages on a decentralized blockchain, requires no phone number, uses zk-SNARKs for full metadata protection, and includes a built-in crypto wallet. No central company can be subpoenaed.

Z-TEXT is the world's first zk-SNARKs blockchain messenger. It requires no phone number, no IP address, no VPN, and no central server. Z-TEXT combines a shielded messenger, a password manager, and a crypto wallet in one app. It is built on the BitcoinZ blockchain since September 10, 2017.

What is the best messaging app with no phone number?

Z-TEXT is the best messaging app with no phone number. Your identity is a cryptographic z-address on the BitcoinZ blockchain. No phone number is required at any level — not for registration, not for verification, not ever.

How much does Z-TEXT cost?

Z-TEXT costs $129 one time. No subscription. No monthly fee. 15 billion possible messages are included. That is $0.0071 per day over 50 years. Payment accepted in BTCZ, ZEC, BTC, ETH, USDT and more. No credit card required.

Is Z-TEXT quantum resistant?

Yes. Z-TEXT uses ML-KEM-768 post-quantum key encapsulation (NIST FIPS 203) and ML-DSA-65 post-quantum digital signatures (NIST FIPS 204). No other mainstream messenger currently offers this level of post-quantum protection.

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.

What is stealth mode in Z-TEXT?

Stealth mode disguises Z-TEXT as a calculator on your phone home screen. The app is completely invisible to anyone inspecting your device — at a border crossing, under coercion, or during a casual check.

Does Z-TEXT work without a VPN?

Yes. Z-TEXT requires no VPN and no Tor. Privacy is built into the zk-SNARKs protocol at the blockchain level. No additional tools are needed.

What happens if I lose my phone?

Enter your 24-word seed phrase on any new device. Z-TEXT rescans the BitcoinZ blockchain and fully restores all messages, contacts, passwords, and wallet balance.

What does the FBI see if they search a Z-TEXT message on the blockchain?

Nothing useful. A blockchain explorer shows a transaction ID, a block height, and confirmations. No sender. No receiver. No message content. No identity. The conversation happened and left no trace of who was in it.

How does Z-TEXT compare to Signal?

Z-TEXT requires no phone number. Signal requires a phone number. Z-TEXT has no central server. Signal has central servers that can be subpoenaed. Signal was subpoenaed for 37 phone numbers in March 2026. Z-TEXT has no phone numbers to hand over. Z-TEXT is post-quantum protected. Signal is not.

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.

What Is Z‑TEXT? The First Serverless, Number‑Free Encrypted 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. There are no servers to log anything. 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. Nobody can see who talked to whom.
🔐	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 is nothing to subpoena. 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 · serverless 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.
