We moved our proof anchoring bridge to the cloud.

Always-on. Zero-PII. Production-ready.

[HEXADECIFY @hexadecify]

We tried to break our own liveness check. It broke.

A pre-recorded video was enough to pass it — so we fixed it: randomized challenge order + screen-replay detection.

Heuristic-tier, not certified yet. But we found it ourselves first.

Scaling across borders by design. 🌍 Excited to announce that Hexadecify now reads Malaysian ePassports alongside Thai ones, without a single line of app code being changed!

[HEXADECIFY @hexadecify]

This week: from a bug report → a proof on-chain. 🧵
NFC read ✓ Passive Auth ✓ Face match (0.83) ✓ Anchored on Sepolia ✓ Ran standalone, no lab setup ✓
Still a prototype — accuracy pilot + security audit next. Try it → https://t.co/5NbTBFVeXQ

[HEXADECIFY @hexadecify]

One line fixed it. 0.83 similarity after. Real hardware finds real bugs.

Thread: the bug that turned every selfie green 🧵
Face match kept scoring near 0.02 — should've been 0.8+. Detection worked fine (uses brightness), but the embedding model needs accurate color. Turned out our camera pipeline was assembling color channels wrong.

This is real code from our SDK. The instant verification finishes, your face is wiped from memory. Never written to disk. Ever.

[HEXADECIFY @hexadecify]

Don't trust us. Verify it yourself.
Every proof we generate lives on-chain, public, forever.
Contract, tx hash, all checkable on Etherscan → https://t.co/4T3yJvJu7i

[HEXADECIFY @hexadecify]

Verified. End to end. 🔒
Real passport → real face match → real proof, anchored on-chain.

Zero PII stored. Check it yourself → https://t.co/4T3yJvJu7i

[HEXADECIFY @hexadecify]

Our first smart contract is now live on Ethereum Sepolia Testnet. 🚀

Every verification can now be anchored on-chain with immutable cryptographic proofs—while storing zero raw PII.

Privacy-first identity starts here.

[HEXADECIFY @hexadecify]

Hexadecify is built upon peer-reviewed cryptographic research, combining modern identity verification with privacy-preserving architecture.

From academic foundations to real-world deployment.

Deep-tech identity.
Privacy by design.

🌐 https://t.co/bvQ7bCv0uv

[HEXADECIFY @hexadecify]

Built on the ICAO 9303 ePassport standard, Hexadecify enables privacy-first identity verification across 150+ countries using any NFC-enabled smartphone.

One global standard.
Zero raw PII stored.

Privacy by design. Global by default.

🌐 https://t.co/bvQ7bCv0uv

[HEXADECIFY @hexadecify]

Traditional identity systems accumulate sensitive personal information that becomes a high-value target.

Hexadecify changes the model.

No centralized storage of raw passport data.
No unnecessary collection.
Just privacy-first verification.

Store proofs. Not identities.

[HEXADECIFY @hexadecify]

Instead of collecting and retaining sensitive documents, Hexadecify transforms successful verification into a verifiable proof.

✔ Verified
✖ No raw identity stored

Less data. Less risk. More trust.

#Hexadecify #ZeroKnowledge #PrivacyTech #Identity

[HEXADECIFY @hexadecify]

Hexadecify verifies passport authenticity and matches the rightful holder—without storing raw personal data.

Read the chip.
Match the face.
Store nothing.

Privacy isn’t an afterthought. It’s the architecture.
