Helium (HNT) is a decentralized blockchain-powered network for Internet of Things (IoT) devices. Launched in July 2019, the Helium mainnet allows low-powered wireless devices to communicate with each other and send data across its network of nodes. Nodes come in the form of so-called Hotspots, which are a combination of a wireless gateway and a blockchain mining device. Users who operate nodes thus mine and earn rewards in Helium’s native cryptocurrency token, HNT. Helium’s goal is to prepare IoT communication for the future, identifying inadequacies in current infrastructure from its birth in 2013.
