Z-TEXT is a zk-SNARKs blockchain messenger. Z-TEXT requires no phone number, no email, and no SIM. Z-TEXT collects zero metadata. Z-TEXT combines a shielded messenger, a password manager, and a crypto wallet in one app. Z-TEXT is built on the BitcoinZ blockchain since September 10, 2017.

What is the best messaging app with no phone number?

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

How much does Z-TEXT cost?

The Z-TEXT Cyberpunk Lifetime License costs $128.52 one time. No subscription. 1 million possible messages are included and the license never expires. Payment accepted in BTCZ, ZEC, BTC, ETH, USDT and more. There is also a Zero Trace 1-month plan at $3.00.

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), alongside AES-256-GCM encryption and zk-SNARKs zero-knowledge proofs.

What is panic mode in Z-TEXT?

Panic mode in Z-TEXT uses a second PIN called the Panic PIN. If you enter the Panic PIN instead of your real PIN, the app wipes itself instantly. 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 working calculator on your phone home screen. You open the calculator and type a secret code as a math equation to unlock the app. To anyone inspecting your device — at a border crossing, under coercion, or during a casual check — it looks like an ordinary calculator.

What happens if I lose my phone?

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

What does the blockchain reveal about a Z-TEXT message?

Very little. A blockchain explorer shows a transaction ID, a block height, and confirmations. No sender, no receiver, no message content, and no identity are exposed.

How does Z-TEXT compare to Signal?

Z-TEXT requires no phone number. Signal requires a phone number. Z-TEXT has no phone numbers to hand over. Z-TEXT is post-quantum protected.

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 zero metadata, requires no phone number, and has no account to seize. Panic mode wipes the app instantly if a device is taken. Stealth mode hides the app as a calculator. Journalists and their sources are protected at every layer.

When does Z-TEXT launch?

Z-TEXT launches Monday, October 5, 2026 on Android, macOS, Windows and Linux at z-text.com. iOS is coming to the App Store.

Does Z-TEXT need a phone number?

No. Z-TEXT needs no phone number, no email and no SIM. Your identity is a 24-word seed.

What does shielded mean in Z-TEXT?

Z-TEXT uses zk-SNARKs, a zero-knowledge proof, so the BitcoinZ blockchain can confirm a message is valid without revealing the sender, the recipient or the content.

Is Z-TEXT quantum-resistant?

The Z-TEXT key exchange is quantum-resistant. It uses ML-KEM-768, the NIST FIPS 203 post-quantum standard.

How much does Z-TEXT cost?

The Z-TEXT wallet is free. Sending messages, the password manager, Channels and new identities need a license code, starting at $3 a month.

Launch, Z-TEXT, zk-SNARKs, Privacy

Z-TEXT Launches Monday: Shielded Permanence Is Coming

Z-TEXT, the zk-SNARKs messenger on the BitcoinZ blockchain, launches Monday, October 5. No phone number, no email, no SIM. Here's what's coming.

2 days. Z-TEXT launches Monday, October 5

Z-TEXT, the privacy messenger built on the BitcoinZ blockchain, launches Monday, October 5, 2026. No phone number. No email. No SIM.

In short: Z-TEXT is five tools on one blockchain, unlocked by one 24-word seed. zk-SNARKs hide who talks to whom. The key exchange is quantum-resistant. The wallet is free. Messaging starts at $3 a month. Android, macOS, Windows and Linux from Monday.

LAUNCH · MONDAY, OCTOBER 5, 2026

Shielded Permanence™ is coming alive!

"Just another messenger?" NO.

Z-TEXT is a wallet-native, censorship-resistant communication layer, where:

• Your audience lives in your wallet
• Your identity is your seed phrase
• Your messages are shielded on-chain
• Your metadata stays hidden
• Your key exchange is quantum-resistant

A fundamentally different model from Signal, Telegram, or any centralized platform.

🎬 A first look inside Z-TEXT

❓ 1. What launches on Monday?

Z-TEXT is five tools on one blockchain: a shielded messenger, a BTCZ wallet, an on-chain password manager, Channels for broadcasting, and disposable identities. One 24-word seed unlocks all five.

Mini-resume: Z-TEXT launches October 5, 2026 as a five-in-one privacy app on the BitcoinZ blockchain, with no account and no phone number.

❓ 2. What does "shielded" mean?

Z-TEXT uses zk-SNARKs, a type of zero-knowledge proof. The blockchain confirms a message is valid without seeing who sent it, who received it, or what it says.

Mini-resume: zk-SNARKs let Z-TEXT prove a message is real while hiding the sender, the recipient and the content.

❓ 3. What does "quantum-resistant" cover?

The key exchange. Z-TEXT uses ML-KEM-768, the post-quantum standard NIST published in 2024.

Mini-resume: Z-TEXT protects its encryption handshake with ML-KEM-768, a NIST post-quantum standard.

❓ 4. What is free, and what is paid?

Free

BTCZ wallet

Reading Channels

Panic PIN + stealth mode

License (from $3 a month)

Sending messages

Password manager

Channels + new identities

Mini-resume: the Z-TEXT wallet is free forever. Messaging needs a license code, from $3 a month.

❓ 5. Where can I get Z-TEXT?

From Monday, October 5: Android, macOS, Windows and Linux at z-text.com. iOS is coming to the App Store. Z-TEXT runs on BitcoinZ, a community blockchain running since 2017: getbtcz.com.

Mini-resume: Z-TEXT is available from October 5, 2026 on four platforms at z-text.com, with iOS to follow.
