From heartbeat to consensus in six steps. Privacy-preserving by design.

Your wearable reads your vitals in real time.
Heart rate, HRV, SpO2, steps, skin temperature, gait entropy, and voice liveness — 7 signals captured continuously by your smartwatch or fitness tracker.
Your device proves you're alive — without exposing your data.
A Halo2 IPA proof is generated on-device. It says "this biometric data is real and human" without revealing actual readings. Your health data never leaves your wrist.
Your proof enters a Directed Acyclic Graph.
A signed event references 2-4 prior events from other participants, creating a web of trust. No blocks, no fixed intervals — events flow as fast as people produce them.
Vitality Score
0.67
Seven biometric signals combine into one score.
V(i) ∈ [0, 1] — weighted by signal importance. Resting earns ~0.55, active earns ~0.65. Presence matters more than performance. Differential privacy adds noise for protection.
2/3+ vital weight confirms finality
The network confirms your event is permanent.
Events become final when 2/3+ of the network's vital weight has transitively referenced them. No probabilistic finality, no forks — once confirmed, it's done.
Heartbeat Reward
Just now
You earn PULSE proportional to your vitality.
Your reward = base reward × vitality score. The event propagates to all peers via QUIC transport. The more alive you are, the more you earn.
