Own your biometric data. Contribute to medical research. Earn $VITAL — all protected by zero-knowledge cryptography on Solana.
VitalNode connects your wearable devices — Apple Watch, Fitbit, Garmin, Oura Ring — aggregates your health data on-device, and lets you anonymously contribute to medical research pools that advance science and compensate you fairly.
Your biometric data is yours by default. VitalNode never stores raw health metrics on centralized servers. You hold the cryptographic keys — and the power to share or revoke access at any moment.
Opt into anonymized research pools where your health patterns — never your identity — help universities and pharmaceutical companies accelerate breakthroughs in cardiovascular health, sleep medicine, and metabolic research.
Research institutions bid for access to aggregated health data pools. When your anonymized patterns are used, you earn $VITAL tokens automatically via smart contracts — no middlemen, no hidden fees.
Six core biometric categories, each contributing unique scientific value to medical research — all processed with zero-knowledge privacy guarantees.
Real-time cardiac rhythm and heart rate variability data. Critical for cardiovascular disease prediction, stress research, and autonomic nervous system studies.
REM cycles, deep sleep duration, sleep stage transitions. Enables neuroscience research into cognitive function, metabolic health, and longevity biomarkers.
Continuous blood oxygen saturation monitoring. Vital for respiratory research, altitude medicine, sleep apnea studies, and early detection of pulmonary conditions.
Daily movement patterns, caloric expenditure, workout intensity. Powers epidemiological research linking physical activity to disease prevention and metabolic outcomes.
Physiological stress markers derived from HRV and skin conductance. Critical for mental health research, burnout prevention studies, and cortisol-related disease pathways.
Continuous core temperature variation tracking. Enables infectious disease surveillance, ovulation cycle research, fever detection, and thermal regulation studies at population scale.
Four transparent steps from biometric data collection to token rewards — with cryptographic privacy at every stage.
Link your Apple Watch, Fitbit, Garmin, or Oura Ring via secure Bluetooth API. VitalNode SDK works natively on iOS and Android.
Biometric data is encrypted on-device using zk-SNARKs before any transmission. Raw values never leave your device in readable form.
Choose which research categories to support. Your encrypted contribution joins anonymized aggregate datasets that researchers bid for access to.
Smart contracts on Solana automatically distribute $VITAL tokens to contributors when research pools are accessed. Transparent, instant, programmable.
Link your wearable via secure Bluetooth API. VitalNode SDK works on iOS and Android.
On-device zk-SNARK encryption before any transmission. Raw data never leaves your device.
Choose research categories. Your encrypted data joins anonymized datasets that researchers bid for.
Solana smart contracts auto-distribute $VITAL when pools are accessed.
Zero-knowledge proofs allow VitalNode to mathematically verify facts about your health data — without ever revealing the underlying values. A researcher can confirm "this person's average resting heart rate is in the healthy range" without seeing a single raw data point.
Raw health metrics are encrypted with your personal keys on-device. VitalNode servers never receive or store plaintext biometric values. Mathematically guaranteed.
ZK proofs enable statistical analysis on aggregated, anonymized datasets. Individual records cannot be extracted, re-identified, or reverse-engineered by any research partner.
Granular consent management lets you enable or disable access to specific data categories at any time. Your participation in any research pool is fully voluntary and instantly revocable.
Enterprise-grade infrastructure combining medical-grade data standards with cutting-edge cryptography and blockchain-native token economics.
20+ supported devices
