Welcome to PoPB — What sensor data would you like to see verified on-chain?

[ZWISERFIT]

Welcome to the PoPB community!

This is the first discussion thread — a conversation starter, not an announcement.

PoPB (Proof of Physical Behavior) is an open protocol for cryptographically verifiable human physical activity data.

We have the protocol running. Hardware deployed since 2019. The spec is open, the verifier runs, and the Pages site is live.

We want to hear from you

• What sensor do you have that would benefit from verifiable proofs?
• What use case feels most urgent?
• What would you build if this protocol worked out of the box?

Quick links

• Protocol Spec v1.0.0
• README
• GitHub Pages
• PIP Proposal

This is an open protocol. The direction is set by the people who show up and build.
