Abstract This talk, presented at EthPrague 2025, introduces "Proof-of-Habitat," a conceptual decentralized protocol designed to address the limitations of centralized data models in smart cities, mapping systems, and environmental protection. By utilizing RF fingerprinting through mobile sensors, Wi-Fi hotspots, and Bluetooth beacons, Proof-of-Habitat aims to validate unique locations securely while preserving privacy with zero-knowledge proofs. The concept prioritizes local participation, ec...
