Six blockchain messengers, eight criteria, every score sourced. Z-TEXT leads on technology and trails on verifiability.

Z-TEXT ranks first on Technology (26/30), last on Verifiability (2/10) and fourth overall (28/40). Every score is sourced.

Six messengers. Eight criteria. Every score sourced. And yes, we scored ourselves too.

Z-TEXT is a private messenger on the BitcoinZ blockchain with no phone number, no email and no SIM. We built a public scorecard of blockchain messengers to answer one question honestly: which one actually protects your privacy best?

We rated six apps on eight criteria, from 0 to 5. Signal is included as the non-blockchain baseline everyone knows. Z-TEXT is in the list, and Z-TEXT does not come first.

Mini-resume

This scorecard rates ADAMANT, Session, Status, Secure Legion, Z-TEXT and Signal on 8 criteria, split into Technology (what the app does, /30) and Verifiability (can outsiders check it, /10). Z-TEXT scores highest on Technology (26/30) and lowest on Verifiability (2/10), for a total of 28/40. Session leads the total with 31/40.

❓ 1. Which blockchain messaging apps are on the market in 2026?

The blockchain messaging app market splits into two families.

On-chain messengers store each encrypted message on a blockchain. Z-TEXT (BitcoinZ) and ADAMANT (its own chain) work this way. ADAMANT writes every message as a blockchain transaction.

Blockchain-linked messengers use a blockchain for identity, a wallet or a node network, but do not keep messages on a ledger. Session runs on the Session Network, Status pairs messaging with an Ethereum wallet, and Secure Legion uses a seed-based identity and sends messages peer-to-peer over Tor.

Also on the market, not scored here: ZChat (Zcash memos), OpenChat (Internet Computer), BChat (Beldex) and XMTP-based wallet chat apps.

Mini-resume

In 2026 the blockchain messaging app market has two families: on-chain messengers that store encrypted messages on a blockchain (Z-TEXT, ADAMANT, ZChat) and blockchain-linked messengers that use a chain for identity or networking (Session, Status, Secure Legion, BChat, XMTP apps).

❓ 2. How were these blockchain messengers evaluated?

Each app gets 0 to 5 on each criterion. 0 means no. 1 means announced but not shipped. 2 to 3 means partial. 4 means yes, with a limit. 5 means yes, shipped and documented.

Criteria 1 to 6 measure Technology: what the app does for your privacy. Criteria 7 and 8 measure Verifiability: whether outsiders can check those claims. The total is out of 40. Every score links to a public source.

Mini-resume

Scale: 0 to 5 per criterion, 8 criteria, 40 points maximum. Technology (criteria 1 to 6, /30) measures what the app does; Verifiability (criteria 7 and 8, /10) measures whether outsiders can check it. Every score is backed by a public source.

❓ 3. Which blockchain messenger needs no phone number?

Criterion 1 — No phone number

ADAMANT — 5/5
No phone, email or social account (whitepaper).

Session — 5/5
Random Account ID backed by a Recovery Password (Session docs).

Status — 5/5
Identity from a recovery phrase, no phone number (Status).

Secure Legion — 5/5
Identity is a Tor .onion address made from a seed (GitHub).

Z-TEXT — 5/5
Identity is a 24-word seed made on your phone (Z-TEXT docs).

Signal — 1/5
Usernames hide your number, but a phone number is still needed to register.

Mini-resume

Every blockchain messenger in this scorecard works without a phone number (5/5). Signal still requires a phone number to register (1/5), even though usernames can hide it from contacts.

❓ 4. Can you recover your messages on a new phone?

Criterion 2 — Message recovery on a new phone

ADAMANT — 5/5
Message history is on-chain and readable from any device (whitepaper).

Session — 2/5
The account comes back, but the network keeps messages about 14 days.

Status — 2/5
Store nodes keep about 30 days of data.

Secure Legion — 0/5
Backup and restore of message history is not available yet.

Z-TEXT — 5/5
24 words restore messages, contacts, passwords and wallet from the BitcoinZ blockchain (Z-TEXT docs).

Signal — 4/5
Opt-in secure backups since 2025 (Signal blog).

Mini-resume

On-chain messengers win on recovery: ADAMANT and Z-TEXT both score 5/5 because messages live on the blockchain. Signal scores 4/5 with opt-in backups. Session and Status keep only recent messages on their networks (2/5). Secure Legion has no restore yet (0/5).

❓ 5. How do they rate on end-to-end encrypted chat?

End-to-end encryption means only the sender and the recipient can read a message. Forward secrecy means each message gets a fresh key, so a stolen key cannot unlock old messages. In this scorecard, 5/5 needs documented forward secrecy.

Criterion 3 — End-to-end encryption

ADAMANT — 4/5
Curve25519 + XSalsa20-Poly1305, keys derived from the account (ADAMANT).

Session — 4/5
End-to-end encrypted; forward secrecy is planned for Protocol v2 (Wikipedia).

Status — 5/5
X3DH + Double Ratchet on all 1:1 chats by default (Status).

Secure Legion — 4/5
XChaCha20-Poly1305 with a hybrid key exchange; forward secrecy not documented (GitHub).

Z-TEXT — 4/5
Three layers: BitcoinZ Sapling zk-SNARKs, X25519 + AES-256-GCM, and ML-KEM-768. One key per contact pair, rebuilt from your seed (Z-TEXT docs).

Signal — 5/5
Double Ratchet plus the post-quantum SPQR ratchet (Schneier on Security).

Z-TEXT makes a deliberate trade-off. Forward secrecy and seed recovery pull in opposite directions: if keys change with every message, a seed cannot rebuild them. Z-TEXT chose recovery. Status chose forward secrecy and, as its own tech page explains, a recovered account cannot read old messages from existing contacts.

Mini-resume

Status and Signal score 5/5 thanks to Double Ratchet forward secrecy. ADAMANT, Session, Secure Legion and Z-TEXT score 4/5. Z-TEXT wraps every message in three layers (zk-SNARKs, X25519 + AES-256-GCM, ML-KEM-768) but uses one key per contact pair so the 24-word seed can restore history.

❓ 6. Is a blockchain messenger really decentralized?

Criterion 4 — Decentralization

ADAMANT — 5/5
Runs its own blockchain node network (ADAMANT).

Session — 5/5
Runs on the Session Network of community nodes (Wikipedia).

Status — 4/5
Peer-to-peer Waku network; store nodes keep recent history (Status forum).

Secure Legion — 4/5
Peer-to-peer over Tor, no company-owned servers (GitHub).

Z-TEXT — 4/5
Messages live on the BitcoinZ blockchain; the app syncs through a lightwalletd server and checks a licence server (Z-TEXT docs).

Signal — 1/5
Central servers run by the Signal Foundation.

Mini-resume

ADAMANT and Session score 5/5 on decentralization. Status, Secure Legion and Z-TEXT score 4/5: Z-TEXT stores messages on the BitcoinZ blockchain but still syncs through a lightwalletd server. Signal is centralized (1/5).

❓ 7. How do they rate on privacy-preserving messaging?

Metadata is the data about your messages: who talks to whom, when, and from where. Encryption hides the words. Metadata privacy hides the relationship.

Criterion 5 — Metadata privacy

ADAMANT — 2/5
Messages are encrypted, but every transaction is public, so sender and recipient addresses are visible on-chain (ADAMANT).

Session — 5/5
Onion routing; the privacy policy says IP addresses are not logged (Wikipedia).

Status — 3/5
Status aims for no metadata leakage over its peer-to-peer relay; a goal, not a proof (Status).

Secure Legion — 4/5
All traffic over Tor, but an "online" heartbeat is sent to contacts (GitHub).

Z-TEXT — 4/5
zk-SNARKs hide sender, recipient and content on the blockchain. Tor is built in but off until you switch it on (Z-TEXT docs).

Signal — 3/5
Sealed sender hides who sent a message, but accounts are tied to phone numbers on central servers.

Mini-resume

Session leads privacy-preserving messaging (5/5) with onion routing. Z-TEXT (4/5) hides sender, recipient and content on-chain with zk-SNARKs, the same privacy technology as Zcash; Tor is optional. ADAMANT scores 2/5 because sender and recipient addresses are public on its blockchain.

❓ 8. Which blockchain messengers are quantum-resistant?

Quantum-resistant means using encryption designed to survive future quantum computers. The threat is "harvest now, decrypt later": recording messages today to break them later.

Criterion 6 — Post-quantum protection

ADAMANT — 0/5
Classical cryptography only (ADAMANT).

Session — 1/5
ML-KEM announced for Protocol v2; not quantum-resistant today.

Status — 0/5
No post-quantum key exchange found.

Secure Legion — 4/5
Hybrid X25519 + ML-KEM-1024 key exchange, in beta (GitHub).

Z-TEXT — 4/5
Hybrid X25519 + ML-KEM-768 on every contact handshake since version 3.7.0; signatures still Ed25519 (Z-TEXT docs).

Signal — 5/5
Post-quantum key exchange plus the SPQR ratchet (Schneier on Security).

Mini-resume

Signal leads post-quantum protection (5/5). Z-TEXT and Secure Legion score 4/5 with hybrid ML-KEM key exchange. Session has announced ML-KEM but not shipped it (1/5). ADAMANT and Status use classical cryptography only (0/5).

❓ 9. Are they open source and independently audited?

This is Verifiability: can outsiders check the claims above?

Criterion 7 — Open source

ADAMANT — 5/5
Open source code (whitepaper).

Session — 5/5
Open source clients (Wikipedia).

Status — 5/5
Open source app and protocol.

Secure Legion — 2/5
Source-available under a non-commercial licence (GitHub).

Z-TEXT — 1/5
The BitcoinZ blockchain is open source; the Z-TEXT app is not.

Signal — 5/5
Open source client, server and library.

Criterion 8 — Independent audit

ADAMANT — 2/5
Internal audit plus a public bounty contest; says an independent audit followed, report not public (ADAMANT).

Session — 4/5
Independent review by Quarkslab in 2021 (Wikipedia).

Status — 3/5
Trail of Bits audit of the mobile app, November 2019 (Status).

Secure Legion — 0/5
No audit yet; planned before 1.0 (GitHub).

Z-TEXT — 1/5
No independent audit yet. An active bug bounty pays researchers in ZEC.

Signal — 5/5
Many independent and academic analyses (Schneier on Security).

Mini-resume

Signal leads Verifiability (10/10), followed by Session (9/10). Z-TEXT and Secure Legion score lowest (2/10). Z-TEXT has no independent audit and a closed app, with only the BitcoinZ blockchain open source and a ZEC bug bounty running.

❓ 10. Isn't a blockchain public?

Yes. A blockchain is a public record that never forgets. That is exactly why the privacy layer matters.

On ADAMANT, messages are encrypted, but all transactions are available to everyone, so the sender and recipient addresses are visible. On Z-TEXT, each message is a shielded BitcoinZ transaction: zk-SNARKs, zero-knowledge proofs, let the network verify a transaction without seeing who sent it, who received it or what it said (Z-TEXT docs).

Mini-resume

A blockchain is public and permanent. A blockchain messenger is only private if the transactions themselves are shielded. Z-TEXT uses zk-SNARKs to hide sender, recipient and content on the BitcoinZ blockchain, running since September 10, 2017.

❓ 11. How does Z-TEXT score?

Z-TEXT — 28/40

Technology — 26/30 — 1st
No phone 5 · recovery 5 · encryption 4 · decentralization 4 · metadata 4 · post-quantum 4

Verifiability — 2/10 — last
Open source 1 · independent audit 1

Z-TEXT has the strongest technology in this scorecard. It is also the least verifiable. Both weak points are decisions, not missing features: publishing the protocol and paying for an independent audit would move Z-TEXT from 28 to 33, the top of the table.

Mini-resume

Z-TEXT scores 28/40: first on Technology (26/30) and last on Verifiability (2/10). An open protocol specification (+2) and an independent audit (+3) would raise Z-TEXT to 33/40.

❓ 12. Which blockchain company offers the best private messaging app?

Final ranking — total /40 (Technology + Verifiability)

Session — 31
22 + 9

Signal (baseline) — 29
19 + 10

ADAMANT — 28
21 + 7

Z-TEXT — 28
26 + 2

Status — 27
19 + 8

Secure Legion — 23
21 + 2

Session wins the total today. Z-TEXT wins the technology. If you want the most verified app right now, pick Session or Signal. If you want no phone number, messages that survive a lost phone and zk-SNARKs privacy on-chain, pick Z-TEXT, and hold us to the audit.

Z-TEXT leads on technology. Now we have to prove it.

Mini-resume

Final ranking: Session 31, Signal 29, ADAMANT 28, Z-TEXT 28, Status 27, Secure Legion 23. Session offers the best overall private messaging app among blockchain messengers today; Z-TEXT has the best technology score.

No phone. No email. No SIM. Zero metadata. Z-TEXT zk-SNARKs privacy.
