Helium is a peer-to-peer wireless network that aims to provide a secure and cost-effective way for low-power Internet of Things (IoT) devices to interact with the internet.
Using Hotspots and other devices for sending and receiving data transmitted from sensors and IoT devices, miners can earn Helium tokens (HNT) by proving they are creating wireless networks in Proof of Coverage Challenges.
Proof of Coverage is a type of Proof of Work (PoW) algorithm that uses radio waves to validate that Hotspots are providing legitimate wireless coverage.
HNT tokens are consumed for the generation of Data Credits, which are used for data transmission and token transaction fees.
The Helium network runs on a blockchain infrastructure with a consensus protocol based on the HoneyBadgerBFT.
