ZK Geo Location Prover
Zero-Knowledge Geo Location Prover for DePIN node
About
The problem it solves The problem to be solved by this project is the provacy-preserving related problem that an exact geo location of a DePIN Device (i.e. Helium, XNET) can be shared. This ZK Geo Location Prover protocol can prove and verify whether or not a DePIN node (device) is working in legal region without revealing their exact locations (GPS coordinates) - thanks to ZKP (Zero-Knowledge Proof) produced via Boundless-powered by RISC Zero's zkVM. In other words, this protocol can attest a "proof of location" without revealing a DePIN Device's exact locations.
How it's made
Challenges we ran into The challenge was how to implement ZK guest program (ZK circuit) for proving a geo location.
