PoC (Proof-of-Coverage )

The Nebra HNT Outdoor Hotspot Miner earns HNT Helium tokens when devices connect, and for validating wireless coverage delivered by peers. Using a system called Proof-of-Coverage, Hotspot Miners earn more HNT when they’re in range of other miners, but need to be at least 300 metres apart.

The range depends on the environment:

Rural areas: ~10 miles or more.
Dense areas: ~ 1 mile.
Single HNT Hotspot Miners earn less as they can only issue Challenges over the internet, and can’t participate in Proof-of-Coverage.

Proof of Coverage Challenges
The “challenge” is the discrete unit of work for Proof of Coverage. To date, there have been 10s of millions of challenges issued and processed by the Helium blockchain. With each new challenge, the blockchain records more data about the quality of the network. Let’s take a look at how challenges actually happen.
