Examples of the present disclosure describe systems and methods for verifying the location of a device using blockchain technology and zero-knowledge proofs (ZKPs). In one example aspect, a system may receive raw geolocation and timestamp data from a device. The geolocation data may be corroborated by other third-party trusted devices in a network. Upon receiving the raw geolocation and timestamp data, the system may construct at least one ZKP. In one example, the ZKP involves determining whether the geolocation of the device is within an authorized region from a database of authorized regions. If the geolocation is determined to be in an authorized region, then a ZKP predicate stating that the device was in an authorized region may be constructed. This ZKP predicate may be written to a blockchain so that a verifier may read the block and verify the device's location without receiving the raw, underlying geolocation/timestamp data.
