Z-TEXT Bug Bounty Is Live. Plus: The Honest Board.
Z-TEXT is a zk-SNARKs blockchain messenger built on BitcoinZ. It requires no phone, no email, and no SIM, and it collects zero metadata. Today Z-TEXT is doing two things at once: opening a live bug bounty, and publishing an honest scored board comparing Z-TEXT to its real competitors.
Most apps tell you to trust them. Z-TEXT would rather you test it.
❓ What is the Z-TEXT bug bounty?
The Z-TEXT bug bounty is a live, open invitation to independent security researchers. Find a real flaw in the Z-TEXT zk-SNARKs blockchain messenger, report it, and get paid.
Z-TEXT runs zk-SNARKs zero-knowledge proofs, AES-256-GCM encryption, and post-quantum cryptography. None of that matters if no independent eyes ever stress it. So Z-TEXT is putting the system in front of people who understand cryptography and real-world attack surfaces — and asking them to break it.

❓ How does Z-TEXT compare to Signal, Session, and Briar?
Below is the honest field guide. Each attribute is scored 0 to 10. Z-TEXT does not win every row, and the board says so out loud. That is the point.
| Attribute | Z-TEXT | S / Se / Br |
| No central message server | 7 | 3 / 8 / 10 |
| No phone number | 9 | 2 / 9 / 9 |
| Hides who-talks-to-whom | 8 | 7 / 9 / 10 |
| Hides your IP from the recipient | 9 | 8 / 8 / 4 |
| Works fully offline | 1 | 1 / 1 / 10 |
| Post-quantum encryption | 9 | 8 / 3 / 3 |
| Recover messages (lost device) | 10 | 4 / 2 / 2 |
| Shielded payments | 9 | 2 / 0 / 0 |
| Password vault | 9 | 0 / 0 / 0 |
| TOTAL (out of 90) | 71 | 35 / 40 / 48 |
| AVERAGE | 7.9 | 3.9 / 4.4 / 5.3 |
Columns after Z-TEXT: Signal (S) / Session (Se) / Briar (Br). Scores are draft estimates, published openly for scrutiny.
❓ Who leads where?
Z-TEXT — highest overall at 7.9. Z-TEXT leads on IP-hiding, post-quantum encryption, message recovery, shielded payments, and the password vault. Z-TEXT is the only one combining all of these in one app.
Briar — true peer-to-peer with no server, and it works with zero internet. But Briar has no recovery, exposes your IP to peers, and runs on a tiny network.
Session — strong anonymity, onion-routed, a solid all-rounder. Session wins no single row outright here.
Signal — the benchmark everyone measures against. Signal's post-quantum work is real: the Triple Ratchet now adds quantum-safe forward secrecy. But Signal still requires a phone number, has no vault, and has no working payments.
❓ Where does Z-TEXT NOT lead?
Honesty first. On "no central message server," Z-TEXT scores lowest at 7. Briar and Session use peer-to-peer designs, so they can claim "no server" more literally.
But that same P2P design exposes your IP to the person you message — which is exactly where Z-TEXT scores highest at 9. The Z-TEXT on-chain model gives the recipient no direct channel to learn your IP. No architecture is free. P2P trades IP-exposure and lost history for a serverless claim.
Z-TEXT keeps lightwalletd in the path. Z-TEXT discloses this openly, and it can be replaced with Tor or a self-hosted node.
Z-TEXT's honest gaps: no independent audit yet, a paid license, and a smaller network than Signal. That is also why the bug bounty exists — to close the audit gap in the open.
❓ What is Z-TEXT, in one line?
Z-TEXT is three tools in one app: a shielded messenger, a password manager, and a crypto wallet. Z-TEXT is built on the BitcoinZ blockchain, whose first block was mined on September 10, 2017. One 24-word seed phrase recovers everything. Each message costs about $0.00003 in network fees.
No phone. No email. No SIM. Zero metadata.
