Z-TEXT, a privacy messenger built on the BitcoinZ blockchain, launches with no phone number, email or SIM. zk-SNARKs hide who's talking; the blockchain never forgets what's said.
SHERIDAN, Wyo., Oct. 5, 2026 /PRNewswire-PRWeb/ -- Z-TEXT, a privacy messenger built on the BitcoinZ blockchain, is now available for download: no phone number, no email, no SIM card, no KYC. Identities are generated from a seed phrase and can be discarded and replaced anytime. zk-SNARKs shield who is talking to whom, and the blockchain gives every message shielded permanence.
PRIVATE: SHIELDED BY ZK-SNARKS
Every message travels as a shielded BitcoinZ transaction. zk-SNARKs are zero-knowledge proofs that let the blockchain confirm a transaction is valid without revealing who sent it or who received it. The message itself is encrypted on the device with AES-256-GCM before it leaves the phone.
No central message server holds Z-TEXT conversations: what exists on-chain is an encrypted, shielded transaction, not a readable transcript.
Live proof from the BitcoinZ explorer: a shielded-to-shielded transaction where both sender and recipient are private. Verify it at explorer.getbtcz.com.
TX hash: 46fea9f91c84675226d71f1030c056e692330f7928344a2d02681f01f1fbc7a2
ETERNAL: SHIELDED PERMANENCE
Most apps treat deletion as safety, but "delete" rarely erases anything. Data often lingers on a disk or on a server.
Z-TEXT messages do not sit in a company's message database. They settle on a decentralized blockchain, with no delete button to reach. Disappearing is surrender, not security.
zk-SNARKs hide who is talking, and AES-256-GCM encryption keeps what is written unreadable to anyone but the recipient.
ONE APP, ONE BLOCKCHAIN, FIVE TOOLS
Z-TEXT combines five tools in one app: a messenger, a BTCZ wallet, an on-chain password manager, a broadcast feature called Channels, and a disposable ID system (a shielded address you can discard and replace at will).
Each identity is its own 24-word seed, and that one seed unlocks all five tools. No phone, no email, no SIM, no separate account for each one.
FOUNDER QUOTE
"I believe in zk-SNARKs the way some people believe in free speech itself," said Eric Pierrot, founder of Z-TEXT. "A whistleblower, a journalist, anyone who needs to speak without being silenced: they shouldn't have to trust a company. The math should protect them, not a privacy policy."
HOW IT WORKS
Z-TEXT is built on three layers:
- The BitcoinZ blockchain: decentralized, permanent, recoverable from a seed
- zk-SNARKs: proving a transaction is valid without revealing sender or recipient
- Quantum-resistant cryptography: ML-KEM-768, live since version 3.7.0, protecting the key exchange against future quantum computers
Sending a message costs 0.0002 BTCZ: a 0.0001 BTCZ network fee plus 0.0001 BTCZ delivered to the recipient. In a normal back-and-forth, that amount comes back with each reply, so the real cost is about 0.0001 BTCZ per message. That is small enough for real conversations and expensive enough to make mass spam pointless.
CREDIBILITY PROOF
BitcoinZ's first block was mined on September 10, 2017: nine years of continuous operation combining Bitcoin's proof-of-work model with Zcash's zk-SNARK privacy, with no premine and no ICO. Its 21 billion BTCZ supply cap keeps individual coins accessible.
Z-TEXT does not own or control BitcoinZ. It is a community-run, GPU-mineable blockchain, not a company-controlled token. A June 2026 independent security review confirmed BitcoinZ's supply integrity.
Z-TEXT also runs an active bug bounty, with rewards up to $1,500 per finding, paid in ZEC from a public, verifiable pool at address t1bV6TkNwWBGBPtGhJCNEQZChpGVivHhHGE, with one payout already on record.
AVAILABILITY
Z-TEXT is available now at z-text.com/downloads for Android, macOS, Windows and Linux. iOS is coming to the App Store. Every build is published with a SHA-256 checksum so anyone can verify the file has not been altered.
Wallet functions, reading saved data and reading Channels are free. A license code unlocks messaging, new password manager entries, Channels posts and new disposable identities, starting at $3 per month at z-text.com/packages, payable in BTC, ETH, ZEC and other major cryptocurrencies. Unused credits never expire.
Signal is now testing phone-number-free sign-up in its Android beta, for a one-time $3 fee. Z-TEXT was built without phone numbers from day one: no phone, no email, no SIM, no KYC, with messenger, wallet, password manager, Channels and disposable IDs in one app.
ABOUT Z-TEXT
