IoTeX Trusted Location API

Trusted Location API is the first W3bstream-based, Layer-2 service that provides trusted GPS location of blockchain users to Web3 dApps. The service is created by MachineFi Lab, the core developers of the IoTeX blockchain.
Users who own enabled devices can configure if and how they want to contribute their GPS location to the service. With the approval of the device owner, dApps can then query the trusted location API to obtain proofs of location for their users, based on geofences and time ranges.
