HNT

Helium Hotspot is a wireless network that provides coverage for low power IoT devices and allows anyone to earn the cryptocurrency Helium (HNT) by building a wireless network in their city. The algorithm used by Helium, called "Proof-of-Coverage" (PoC), verifies the location of Hotspots to ensure that they are where they claim to be. There is no pre-mining of HNT, and the maximum supply of HNT is 223 million. HNT is mined by compatible Hotspots, and the supply is halved every two years. Hotspot owners receive a higher proportion of HNT in the early days of the network to incentivize building and securing coverage, but as the network grows, Hotspots earn more for transferring device data while Helium Inc. and investors earn less. After 20 years, the distribution of HNT remains fixed.
