What is Pulse?

Pulse is a DAG-based distributed ledger where your heartbeat replaces mining. Instead of burning electricity to secure the network, Pulse uses zero-knowledge proofs of real biometric data from wearables — heart rate, HRV, SpO2, steps, temperature, gait, and voice — as proof that you're a living, participating human. Your raw health data never leaves your device.

This is called Zero-Knowledge Proof-of-Life. The more people pulsing, the more secure the network becomes. No GPUs, no staking capital — just life. Post-quantum cryptography keeps it secure for the long term.

How it works

  1. Your wearable captures heart rate, HRV, SpO2, steps, temperature, and gait data
  2. Your device generates a Halo2 zero-knowledge proof — proving the data is real without revealing it
  3. A signed DAG event referencing 2-4 parent events is broadcast to the network
  4. aBFT consensus finalizes the event when 2/3+ of vital weight has seen it
  5. You earn PULSE tokens proportional to your multi-modal vitality score
💡 Note:PULSE runs on its own DAG ledger — it's not an Ethereum or Solana token. Cross-chain bridges to Solana, Ethereum, BSC, and Polygon are built-in for trading.

Key concepts

  • Wallet — a Ed25519 keypair. Your public key is your address. No signup needed.
  • Heartbeat — a signed DAG event containing a zero-knowledge proof of your biometric data.
  • DAG Event — a node in the Directed Acyclic Graph, referencing 2-4 parent events. Replaces linear blocks.
  • Node — a device running the Pulse software that validates proofs, participates in aBFT consensus, and stores the DAG.
  • Vitality Score — your multi-modal biometric score (7 signals) from 0 to 1. Higher vitality = more rewards.
