1️⃣ Introduction
Problem — Verifying Geolocation Trustlessly
In many blockchain and distributed applications, knowing where a node or user is located is essential for:
- Regulatory compliance (e.g., geofencing certain jurisdictions)
- Content delivery optimization
- Fraud prevention
- Proof-of-presence protocols in IoT or supply chains
The Challenge:
Geolocation on the internet is usually verified via IP-based lookup or self-reported coordinates. Both methods suffer from:
- Spoofing — A malicious actor can use VPNs, proxy servers, or manipulated GPS data to fake their location.
- Centralization Risk — Reliance on trusted third-party geolocation services means that verification can be biased, unavailable, or compromised.
- Byzantine Behavior — In adversarial environments (like blockchain), some participants may actively manipulate delay measurements or submit falsified proofs to mislead the system.
- Network Noise & Measurement Errors — RTT measurements over the internet are noisy due to routing variations, congestion, and jitter, making raw delay-to-distance conversions unreliable.
Without a trustless, decentralized, and robust geolocation verification method, location-dependent blockchain applications remain vulnerable to fraud.
