A phone passes nearby
A participating phone detects a registered device's Bluetooth service when it comes within radio range.
Evidence for the physical world
Trust what is
on the ground.
GPS can be spoofed. Self-reported uptime can be wrong. Pathnod is building independent, privacy-conscious observations for physical networks.

01 — The blind spot
Networks know what a device reports.
Not always what is there.
Imagine a network paying thousands of chargers, hotspots or sensors for being deployed where they claim. A device-reported GPS coordinate alone is not independent evidence.
Physical inspections do not scale. Pathnod explores a new layer of observation: nearby smartphones interacting directly with devices over Bluetooth.
THE QUESTION
How can an operator gain confidence that infrastructure is actually present, without sending an inspector to every site?
02 — The approach
A different kind of
field evidence.
Built around local interaction, independent witnesses and measured confidence—not a single “verified location” claim.
The device responds
A fresh challenge asks the device to sign a response with its own key, linking the observation to that device.
Signals add up
Multiple observations can give operators a stronger, auditable signal than self-reporting alone.
WHAT THIS DOES NOT CLAIM
A nearby observation is not proof of exact GPS location, a unique human, or the absence of collusion. Those limits shape the product.
Where we are
Building the first
real-world test.
Pathnod is in an early validation stage. We are prototyping the device–phone exchange and speaking with physical network operators. The broader privacy and on-chain architecture is a direction under development, not a deployed guarantee.
