Trust-Free Proof of Location for 
AVSes
Validate geographical locations of nodes running EigenLayer AVSes without any trust assumptions
What is Proof of Location
A decentralized proof of geolocation that validates the geographical location of devices connected to the Internet without requiring trust in centralized authorities.
Location claims are verified through a distributed network of EigenLayer operators using Witness Chain's Proof of Location protocol.
Tamper-proof location attestations using advanced cryptographic techniques and blockchain technology for immutable records.
EigenLayer operators stake to ensure honest behavior. False location claims incur slashing, ensuring a robust, trust-minimized system via cryptoeconomic guarantees.
How Proof of Location Works
Our decentralized challenge system ensures trust-free location verification through a multi-step process involving smart contracts, challenge coordinators, and distributed challengers.
Challenge Process Flow
The complete lifecycle of a Proof of Location challenge from initiation to completion
Challenge Initiation
User submits location challenge request to smart contract, which generates a unique challenge ID
Challenger Selection
Challenge coordinator selects distributed challengers from the pool and initiates the verification process
Ping & Response
Prover sends pings to selected challengers, who respond with timing data for distance calculation
Result Aggregation
Estimator service processes delay data and calculates final location verification results
