Z-Text is building temporary messaging identities without phone numbers

Z-Text LLC is developing a temporary messaging identity that lets users create a separate cryptographic identity without a phone number, SIM card or email. The feature is in active development inside the company’s private beta as Z-Text prepares a planned release in early October 2026.

Why it matters: - Z-Text is trying to give users a disposable messaging identity that is separate from a primary account. - The feature is aimed at short-term conversations that users do not want tied to a phone number, SIM card or email address. - The company is positioning the feature as a privacy tool, not a way to erase blockchain history.

What happened: - Z-Text LLC said it is developing a temporary messaging identity for its blockchain-based messaging app built on BitcoinZ. - The planned feature would let a user create a separate cryptographic identity for temporary communication. - Z-Text proposed a $3 fee to create the identity. - Founder Eric Pierrot said the feature follows the same design principle as the rest of Z-Text: messaging does not require a phone number. - Z-Text is operating a private beta program and is preparing for a planned application release in early October 2026.

The details: - The temporary identity is designed to be separate from a user’s primary Z-Text identity. - The disposable identity would have its own local key. - Removing that local key would stop access to the identity through that key. - Removing the local key would not delete information already recorded on the BitcoinZ blockchain. - Z-Text says the application derives identity from a 24-word seed phrase rather than a phone number, email address or SIM card. - The broader Z-Text application combines private messaging, a cryptocurrency wallet, password management, on-chain Channels and disposable identities. - Z-Text says the app uses zk-SNARKs-based privacy technology and a hybrid key-exchange design involving ML-KEM-768 and X25519. - The company has published a technical threat model describing the application’s design and known limitations. - Z-Text is also operating a funded bug bounty program while preparing for an independent security audit. - The company said the temporary-identity feature is still in active development and has not been independently audited. - Additional technical information is available through the company’s technical explainer: Technical explanation of the planned feature. - Z-Text also lists packages and pricing here: Packages and pricing.

Between the lines: - Z-Text is drawing a hard line between local identity control and blockchain immutability. - That distinction matters because users may be able to abandon access to a disposable identity without removing the underlying on-chain record. - The $3 creation fee suggests Z-Text is treating disposable identities as a paid feature rather than a free privacy option. - The mention of a threat model, bug bounty and planned audit indicates the company is trying to build credibility before launch.

What's next: - Z-Text said the temporary-identity feature remains in development. - The company is expected to keep the feature in private beta as it moves toward the planned early-October 2026 release. - Z-Text said more technical details are available in its explainer as development continues.
