Z-TEXT zk-SNARKs Messenger Opens to the Public: No Phone, No SIM

Z-TEXT, a privacy messenger built on the BitcoinZ blockchain, is now available for download with no phone number, no email, no SIM card, and no KYC. Identities are generated from a seed phrase and can be discarded and replaced at any time. Zero-knowledge proofs shield who is messaging whom, while the blockchain gives every message permanence instead of a forced expiration date.

Every message is shielded using zk-SNARKs. zk-SNARKs are a proof system that lets the blockchain confirm a message is valid without revealing who sent it, who received it, or what it says. Message content is encrypted on the sender’s device before it leaves. Z-TEXT does not hold the keys needed to read it.

Most messaging apps treat deletion as a safety feature. But deleting a file rarely erases it, because the data often lingers on disk or on a server. Z-TEXT’s message layer runs on a decentralized blockchain and does not rely on a single company-owned message server. The company describes this as “shielded permanence”: private enough that no one can read a message, and permanent enough that no one can erase it.

Z-TEXT combines five functions on one blockchain: a messenger, a BTCZ wallet, an on-chain password manager, a broadcast feature called Channels, and a disposable identity system. Each identity is its own 24-word seed. That one seed unlocks all five functions, with no separate account required for any of them.
