Helium (HNT) is a decentralized blockchain network that enables users to earn tokens by providing wireless coverage for IoT devices. Using a proof-of-coverage consensus algorithm, Helium incentivizes individuals to set up Hotspots that act as hubs for IoT communication. These Hotspots mine HNT tokens by validating wireless coverage and data transfer. Helium aims to create a low-power, long-range network for IoT devices, allowing for secure and efficient data transfer without the need for traditional cellular networks.
