Z-TEXT — zk-SNARKs Blockchain Messenger. No Phone. No Email. No SIM. Zero Metadata.

What is Z-TEXT?

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. Z-TEXT uses zk-SNARKs zero-knowledge proofs combined with AES-256-GCM encryption and post-quantum protection. Panic mode and stealth mode are included. One 24-word seed phrase recovers everything. Z-TEXT is a private messaging app for journalists, activists, and crypto users.

Z-TEXT vs Signal vs Telegram vs WhatsApp

Signal requires a phone number. Telegram stores messages on central servers. WhatsApp shares your data with Meta. Z-TEXT requires no phone number, no email, no identity. Z-TEXT is a censorship resistant blockchain messenger with zero-knowledge proof privacy.

"Memory that never fades. Privacy that never breaks. That's Z-TEXT."

The internet only knows two settings. Forget, or expose. Your messages vanish the second you close the app — or they sit on a company's server forever, readable by anyone who asks the right way.

There was never a third option. Until now.

Z-TEXT is the elephant in the room. The one messenger with private eternal memory. Your words, kept forever — and seen only by you. Not deleted. Not exposed. Remembered, privately, for eternity.

Memory that never fades. Privacy that never breaks. That's Z-TEXT.

❓ What did Z-TEXT just do?

Z-TEXT did something a company is not supposed to do.

Z-TEXT wrote down what it believes — a manifesto on the right to a private conversation — and placed it somewhere Z-TEXT can no longer reach to change it or take it down.

It lives on IPFS, a decentralized network where a file is held by its content, not by any server a company owns. No host to pressure. No button to delete. Z-TEXT gave up control on purpose.

And Z-TEXT wrote the manifesto's fingerprint into the BitcoinZ blockchain itself. A permanent timestamp. Proof that on this day, these words existed — kept the way Z-TEXT keeps everything. Privately. For eternity.

❓ Why does this matter?

Things disappear from the internet every day. A post gets deleted. A site goes dark. A company folds and takes everything it ever said with it.

Z-TEXT is two people. No investor. No safety net. Real privacy has a cost, and Z-TEXT pays it. Maybe Z-TEXT survives. Maybe it doesn't.

But the manifesto stays. That part is already out of our hands.

The right to a private conversation shouldn't depend on who holds power this year. Organizations like the Electronic Frontier Foundation and Reporters Without Borders have spent decades making that case. Z-TEXT built a messenger that lives it — and a manifesto that outlives it.

The Z-TEXT Manifesto

The right to a private conversation.

Every conversation you have ever had built the person you are. The ones that shaped you most were private. A word to a friend. A confession. A doubt said out loud before you were ready to defend it. None of that happened under watch. That was the point.

Surveillance changes what people are willing to say. A person who knows they are being recorded edits themselves, hesitates, stays quiet. This is called the chilling effect, and it is not an accident. It is the purpose. Power has always understood that the cheapest way to control what people do is to control what they feel free to say.

Today that watching is industrial. Governments scan messages and call it safety. Companies harvest metadata and call it product. The justification changes with the decade — terrorism, child safety, fraud, order — but the machine underneath is the same machine, and it is always pointed at the individual.

The trap of identity

Almost every messenger asks for a phone number. That number is not a detail. It is the thread that ties every private word back to a SIM, a carrier, a legal name, a home. Hold that thread and you hold the person. Most of the privacy industry has spent a decade improving the locks while leaving that thread in place.

Z-TEXT cuts the thread. No phone. No email. No SIM. Your identity is a 24-word seed phrase and nothing else. There is no central directory of users to subpoena, and no company database that turns a name into a target.

Z-TEXT is built on BitcoinZ, a blockchain running since 2017, using zk-SNARK zero-knowledge proofs — the mathematics that lets a message be proven real without revealing who sent it, who received it, or what it said. Privacy here is not a promise written in a policy. It is the architecture.

What we believe

01   Privacy is not secrecy. A person can have nothing to hide and still deserve a door that closes.
02   Metadata is content. Who you spoke to, when, and how often can reveal more than the words ever could.
03   The right to a private conversation should not depend on the mood of whoever holds power this year.
04   An honest tool states its limits. Z-TEXT publishes its own threat model and runs a live bug bounty, in the open.
05   What can be erased can be censored. So this is placed where it cannot be erased.

If you are reading this years from now, in a place where it was supposed to be gone — that was the whole idea.

Written for everyone who still believes a conversation can be their own.

Memory that never fades. Privacy that never breaks. That's Z-TEXT.

This manifesto is also published un-censorably on IPFS and timestamped on the BitcoinZ blockchain. For the permanent version: manifesto.z-text.org
