Z-Text Develops Temporary Messaging Identity Without Identifiers

SHERIDAN, WY, UNITED STATES, September 28, 2026 /CourierPR/ -- Z-Text LLC, a blockchain-based messaging application built on BitcoinZ, is developing a new feature designed to provide users with a separate cryptographic identity for temporary messaging. The planned feature would allow a user to create a separate identity for short-term communication, without the need for a phone number, SIM card, or email address. The company is currently operating a private beta program and is preparing for a planned application release in early October 2026.

The temporary identity feature is part of the broader Z-Text application, which combines private messaging, a cryptocurrency wallet, password management, on-chain Channels, and disposable identities. According to the company, the disposable identity would have its own local key. When the user removes that key, access to the identity would no longer be available through that key. Removing the local key would not delete information already recorded on the BitcoinZ blockchain. Z-Text therefore distinguishes between removing local access to an identity and removing data from the blockchain.

The company is not presenting the planned feature as a method for making blockchain messages disappear. The disposable identity is designed to be separate from a user's primary Z-Text identity and intended for temporary communication. A temporary identity can be useful when someone does not want a short-term contact or conversation connected to their primary identity, according to Eric Pierrot, the founder of Z-Text LLC.

The planned feature is designed to be an extension of the application's existing account architecture, which does not require a phone number, SIM card, or email address for identity creation. The feature is based on a hybrid key-exchange design involving ML-KEM-768 and X25519, and derives identity from a 24-word seed phrase rather than requiring a phone number. The company has published a technical threat model describing the application's design and known limitations, and is operating a funded bug bounty program while preparing for an independent security audit.

The temporary-identity feature remains in active development and is not being presented as a completed, independently audited feature. Z-Text is currently available through a private beta program, with a planned application release in early October 2026. Additional technical information about the planned feature is available through the company's technical explainer.

The application, which combines private messaging, a cryptocurrency wallet, password management, on-chain Channels, and disposable identities, is built on BitcoinZ and is designed around shielded blockchain communication, zk-SNARKs-based privacy technology, and identity creation without requiring a phone number, email address, or SIM card. Z-Text has published a technical threat model describing known limitations and operates a funded bug bounty program.
