PROOF OF
PULSE.
Biometric attestation on NEAR.
Upload heart rate data, get a cryptographic proof on-chain. No raw data exposed — only the proof.
FOUR STEPS. ONE PROOF.
Upload
Export HR data from Apple Health. XML or use the built-in demo data.
Analyze
Engine detects fraud, computes HR zones, and scores confidence 0–100.
Attest
Oracle submits proof to NEAR. Raw data goes to an encrypted NOVA vault.
Verify
Any dApp can verify the attestation with a single cross-contract call.
GENERATE YOUR PROOF.
Using server-side data/export.xml
Apple Watch app — auto-sync workout data directly from your wrist. Grant permission once and your heart rate data flows automatically. No manual exports.
Parse
Heart rate samples are extracted from your Apple Health export — or streamed directly from the Apple Watch app.
Detect
The engine checks for fraud: flat data, erratic swings, missing warmup patterns.
Score
A confidence score (0-100) is computed from duration, variability, sampling density, and HR range.
Prove
The attestation is signed and submitted to the NEAR blockchain. Raw data stays encrypted in NOVA.
