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 SimpleX relay operators read channel content?

Yes. SimpleX Channels hide who owns and follows a channel, but channel content is still visible to relay operators while stored. Z-TEXT Channels run directly on BitcoinZ blockchain with zk-SNARKs + AES-256-GCM, so no relay or operator can read content. Only followers with the viewing key can.

Is there a private SimpleX Channels alternative?

Yes. Z-TEXT Channels are the private alternative to SimpleX Channels. SimpleX protects WHO you are, Z-TEXT protects WHO + WHAT you post. Z-TEXT has no relay, no server, no company. Content is zk-SNARKs shielded on BitcoinZ blockchain since 2017 and recoverable with 24-word seed.

Is SimpleX or Z-TEXT better for permanent channels?

For permanent channels, Z-TEXT is better. SimpleX relays hold messages only until delivered, then delete them. Z-TEXT writes one shielded transaction to BitcoinZ blockchain - permanent, thousands of independent computers store it. Reading is always free, history never disappears.

SimpleX Channels vs Z-TEXT: Content Privacy Explained

WHO vs WHAT Privacy comparison

⚡ Quick Verdict: SimpleX Channels [launched April 2026] hide WHO owns and follows a channel. No relay knows your identity. But the channel content is still visible to relay operators. Z-TEXT goes further: content AND identity are zk-SNARKs shielded on the BitcoinZ blockchain. No relay. No operator. No company.

The Core Difference: WHO vs WHAT

SimpleX = Privacy of WHO
SimpleX relays don't know who you are. That's powerful. No phone, no ID. Your channel owner identity is hidden from the relay.

But relays hold your channel messages until followers download them, then delete them. And while they hold them, relay operators can read the content. SimpleX docs confirm this.

Z-TEXT = Privacy of WHO + WHAT
Z-TEXT Channels run directly on the BitcoinZ blockchain. There is no relay. There is no operator.

One post from you equals one shielded transaction. zk-SNARKs + AES-256-GCM. Nobody reads it - not the network, not an outsider. Only followers who hold your viewing key.

Your followers restore from 24 words even if they lose their phone.

What SimpleX Does Better - Be Honest

SimpleX is free. Z-TEXT is a paid license. That's upfront.

SimpleX has independent security audits from Trail of Bits. That's serious credibility.

If you need free, temporary, anonymous chat where history doesn't matter - SimpleX is excellent.

What Z-TEXT Does Better

If you need permanent, uncensorable broadcast.

SimpleX relays hold messages only until delivered. For a channel with 10,000 followers, that's a lot of temporary storage. History is gone.

Z-TEXT keeps everything. Permanently. On BitcoinZ blockchain. Thousands of independent computers worldwide. Not one building someone can raid.

One post, one transaction. Same fee whether 10 people follow you or 10,000. Reading is always free.

No company in the loop. No server to seize. No support desk to delete you. No policy team to ban you.

Resilience: What Can Take Your Channel Down?

A support ticket? No.
A policy violation? No.
A court order? No - there's no company to serve it to.

One honest limit: your channel exists as long as the BitcoinZ network exists. That's thousands of independent computers since September 10, 2017.

Final Verdict

Telegram channels can be deleted. WhatsApp channels are watched by Meta. SimpleX Channels protect who you are, not what you post.

Z-TEXT Channels run on the BitcoinZ blockchain itself — no company, no relay reading your content. Your followers restore from 24 words. One seed. Total resurrection..
