Helium is an Internet-of-Things developer platform for building the network and transferring IoT device data. The platform builds the peer-to-peer wireless network to simplify connecting anything to the Internet by rewarding anyone to become a network operator. It provides wireless coverage for low-power Internet of Things (IoT) devices and earns a new cryptocurrency, Helium, from your living room. Helium tokens are earned by verifying network transactions, adding new blocks to the blockchain, and performing other tasks. The Proof-of-Coverage is a unique work algorithm that uses radio waves to validate that hotspots are providing legitimate wireless coverage.
