Z-TEXT - zk-SNARKs messenger. No phone, no email, no SIM.

by•
Private messenger with no phone number, no email, no SIM. New: Shielded Permanence™. Messages live permanently on the BitcoinZ blockchain and stay unreadable thanks to zk-SNARKs. The proof a message exists is public. Everything else is invisible. One 24-word seed runs 5 tools: messenger, BTCZ wallet, password manager, Channels and disposable identities. Stealth mode hides the app behind a calculator. Quantum-resistant key exchange (ML-KEM-768). Android, macOS, Windows, Linux.

Hi Product Hunt 👋 I'm Eric, founder of Z-TEXT. Why I built it: every messenger promises your messages disappear. But deleted data rarely disappears, and almost every app still wants your phone number. Z-TEXT does the opposite: - No phone, no email, no SIM. Your identity is a 24-word seed. - Messages are shielded transactions on the BitcoinZ blockchain: zk-SNARKs hide sender, recipient and content. You can see one live on the public explorer. - No central message server holding your chats. Honest limits: the app hasn't had an independent audit yet (we run a public bug bounty paid in ZEC), and iOS is still on its way. Reading is free. A license code starts at $3/month and includes BTCZ fuel for your messages. Ask me anything, especially the hard questions. 🙏

Hi Product Hunt, I'm Eric, founder of Z-TEXT.

I believe in zk-SNARKs the way some people believe in free speech. A journalist or a whistleblower shouldn't have to trust a company. The math should protect them, not a privacy policy.

So I built a messenger that never asks for a phone number. Your identity is 24 words.

What's new: Shielded Permanence™. Your messages can't be erased, and no one but the recipient can read them. Not even us. Honest limits: • Text only, no photos or voice. •

The app isn't independently audited yet.
There's a public bug bounty and a published threat model.

• iOS is coming to the App Store. Ask me the hard questions. I'll answer every comment today.

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.

Why blockchain?

So there's no central message server to seize, hack or shut down.

zk-SNARKs prove each message is valid without revealing who sent it or to whom.

Maker

Why pay?

The wallet and reading messages are free, forever.

Sending needs a license, from $3 a month. We're self-funded with no ads, so you pay with money, not with your data.

Your metadata stays hidden

Maker

Lost phone?

Type your 24 words on any device: messages, contacts, wallet and passwords come back. Lose the 24 words, and nobody can recover them.

Not even us
