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.

Can I verify a Z-TEXT shielded transaction?

Yes. Shielded Z-TEXT transactions are visible on the public BitcoinZ explorer at explorer.getbtcz.com: the transaction exists, but sender and recipient show as private.

Shielded Permanence™: Private Messages That Last Forever

Shielded Permanence™: Z-TEXT messages are permanent on the BitcoinZ blockchain and unreadable thanks to zk-SNARKs. No one can erase them. No one can read them.

The proof is public. Everything else is invisible.

Shielded Permanence™ is the privacy model behind Z-TEXT, the blockchain messenger with no phone number, no email and no SIM.

Z-TEXT messages are permanent on the BitcoinZ blockchain, so no one can erase them. zk-SNARKs make them unreadable, so no one can read them except the recipient.

The proof a message exists is public.
Everything else is invisible.

❓ What is Shielded Permanence™?

Shielded Permanence™ is a messaging model with two properties at once:

Permanent: every Z-TEXT message is written to the BitcoinZ blockchain, a public ledger running since September 2017. No company can delete it.
Shielded: zk-SNARKs hide who sent the message, who received it and what it says.

Most messengers sell deletion. Z-TEXT sells something else: messages no one can read and no one can erase.

❓ How does Shielded Permanence™ work?

zk-SNARKs (zero-knowledge proofs) confirm a message is valid without revealing sender, recipient or content. Same technology as Zcash (Sapling protocol, Electric Coin Co.).
AES-256-GCM encrypts the text on the phone before it leaves.
ML-KEM-768 protects the key exchange: quantum-resistant.
The BitcoinZ ledger stores the shielded message permanently. No central message server.

❓ Why not disappearing messages?

Because "delete" rarely deletes. The data often stays on the drive until it is overwritten, and the other person still has their copy, their backups, their screenshots.

Disappearing is surrender, not security.

Encrypted

Locked, but the box still exists and someone holds the key.

Deleted

Hidden, often recoverable.

Shielded Permanence™

Stays forever on the BitcoinZ ledger. zk-SNARKs hide who, to whom and what. Nothing to recover, because nothing readable was ever exposed.

❓ Can I verify it?

Yes. Here is a real shielded Z-TEXT transaction on the BitcoinZ explorer. It exists. Sender and recipient show as private.

👉 See it live on explorer.getbtcz.com

Believe what you see.

❓ And my phone?

Permanent doesn't mean exposed. What you control is your device:

Stealth mode: Z-TEXT hides behind a working calculator, "Calculator Pro." Only your secret sum opens it.
Panic PIN: wipes keys, seed and history from the device in one move.
24 recovery words: bring everything back on a new phone.

Lose the phone. Keep the conversation.

❓ Who is Shielded Permanence™ for?

Journalists protecting sources
Activists and whistleblowers who can't trust a company
Crypto users who want messages, wallet and passwords under one seed
Anyone leaving WhatsApp, Telegram or Signal who doesn't want to give a phone number

Real privacy isn't a promise or an ideology. It's math: zk-SNARKs.
