Abstract: Disclosed herein are systems and methods for providing and using a decentralized network using a blockchain. A provider (and/or miner) may provide network coverage to one or more devices in return for tokens on the blockchain. The blockchain may employ a proof-of-coverage scheme to verify (and even guarantee) that the miners are honestly representing the wireless network coverage they are providing. In some instances, the proof of coverage may require the providers to prove coverage periodically, upon demand, and/or at random intervals.

A vehicle computing device can implement the door interface component and/or an authentication component to control operation of a door of the vehicle or initiate a communication for assistance. For instance, the door interface component can include a button, that provides different visual indicators and functionality based on whether the user is authorized to enter the autonomous vehicle (e.g., open a door or provide visual indicators for the user to select to cause the door to open) or to request to move the vehicle, initiate hiring the vehicle, or call for help when the user is unauthorized to enter the autonomous vehicle.
