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.
