One of the more unique aspects of the @Helium Network is the Consensus Protocol. Proof-of-Coverage (#PoC) is used for sybil resistance and to periodically select a new #HoneyBadgerBFT group. 
Ask any Hotspot host and they will tell you how they dream of joining the coveted Consensus Group - a small group of Hotspots on #ThePeoplesNetwork that receives 6% of all $HNT mined per epoch.
Let’s take a walk back in time, shall we? We first read @socrates1024 #HoneyBadgerBFT paper in 2018. Our implementation was similar to @ethereum, using the GHOST protocol and @bitcoin #NakamotoConsensus to select a winner for each block.
How exactly do Hotspots mine $HNT? You asked. We answer.
The amount of $HNT Hotspots mine depends on the type of “work” they perform based on the value to the network. This validation of network contribution is accomplished by a new work algorithm called Proof-of-Coverage (PoC).

There are 5 types of work a Hotspot can participate in:
1. PoC CHALLENGER: Hotspots are chosen by the network to issue “challenges”, or encrypted messages, over the Internet to a target group of Hotspots. Challenges are used by PoC to validate wireless coverage.
1. PoC CHALLENGER: Hotspots are chosen by the network to issue “challenges”, or encrypted messages, over the Internet to a target group of Hotspots. Challenges are used by PoC to validate wireless coverage.
2. PoC CHALLENGEE: Hotspots validate nearby wireless coverage by broadcasting challenges received from challengers using Radio Frequency (RF). The amount of $HNT each Hotspot earns depends on whether any of these RF broadcasts are received by other nearby Hotspots.
