Proof of Physical Behavior (PoPB) Protocol

v1.0.0 — Request for Comments · MIT / Apache 2.0

PoPB is an open, hardware-anchored protocol for generating verifiable proofs of human physical behavior — capturing real-world movement as native on-chain assets.

Abstract

PoPB establishes a cryptographically secure bridge between real-world human movement and on-chain verifiable proofs. Each proof is:

  1. Hardware-Anchored — signed by a factory-provisioned secure element at the moment of occurrence
  2. Privacy-Preserving — MPC-sharded raw data with ZK-proofs, user-controlled DID
  3. Open-Source — MIT/Apache 2.0, fully auditable
  4. Model 5: Physical-Native RWA — the proof IS the asset, no tokenization needed
