How it works
Your phone holds the evidence. The network holds the proof.
The entire design follows one rule: the sensitive material stays with you, and everyone else gets answers. Here is the pipeline, in plain language.
Part one — on your device
-
Capture happens on your phone
Document scan (front and back), a selfie with active liveness challenges, and — for the highest level — fingerprint or iris through your phone's secure hardware.
-
Reading and checking happen on your phone
The document's text is read automatically (OCR) and quality checks run locally: edges, glare, face confidence, liveness gating. You review everything.
-
Encryption happens on your phone
Before anything is transmitted, the evidence is sealed with envelope encryption (X25519-XSalsa20-Poly1305). From this moment, your evidence is ciphertext everywhere except your device.
Part two — on the network
-
Verification runs inside trusted processing units
Your encrypted submission is opened only inside hardware-sealed enclaves — trusted processing units the chain checks by fingerprint before any data enters. Machine-learning models assess document authenticity, face match and liveness in an environment no operator can look into; raw data is destroyed when scoring ends.
-
Results are recorded, evidence is not
The network records the outcome: your verification level and pass/fail results, plus encrypted references. Your documents and biometrics are never written to the chain in readable form.
-
Your level becomes usable everywhere
Any participating service can now ask the network to confirm your identity — with your consent, per request — without any service ever holding your documents.
Why split it this way?
Conventional identity systems copy your documents into a central database — and central databases get breached. This design means there is nothing central to raid: your evidence exists in readable form only on your device, and the network holds tamper-proof results.
Inside the trusted processing unit
The step that deserves the closest look is the processing itself. Your encrypted evidence is opened only inside a hardware-sealed vault whose key is forged in the hardware and never exists outside it — and the chain checks the vault's exact fingerprint before any data enters.
When a service asks about you
Verification happens once. Sharing happens as often as you approve it — and only what you approve. Two screens do all the work:
What each party ends up holding
| Party | Holds | Never holds |
|---|---|---|
| You | Everything — your evidence, your keys, your consent history | — |
| The network | Encrypted payloads, verification results, consent records | Readable documents or biometrics |
| A service you approve | Your verification level and the specific answer you approved | Documents, photos, biometric data, unconsented scopes |
| Everyone else | Nothing about you | Everything |
