The other day we shared a thread on the 5 types of work a Hotspot can perform to mine $HNT. Today we take a look at the work of a Challenger in Proof-of-Coverage (PoC).

Challenges are used by PoC to validate wireless coverage. As a Challenger, your Hotspot is chosen by the network to create a challenge, or encrypted multi-layer packet, over the Internet.
The challenge process begins with the Challenger selecting an initial target Hotspot, followed by a group of Hotspots known by the @helium blockchain to be within range of each other as a result of RF witnessing.
These Hotspots are given a multi-layer packet (think an “envelope of envelopes”) that only they can decrypt to prove they are providing legitimate wireless coverage.
The Challenger could be anywhere in the world and does not need to be co-located near other Hotspots. Challenge requests occur every 120 blocks, and if the consensus group accepts the challenge transaction as being valid, the challenge proceeds.
One very cool thing about public key cryptography is that data can be encrypted for decryption by a specific recipient while only knowing the recipient's public key. This allows the Challenger to encrypt each layer of the packet specifically for only certain Hotspots to decrypt.
The Challenger delivers this multi-layered packet via the Internet #p2p network to the first Hotspot in the challenge path.
Once Challengees and Witnesses broadcast and receive the layers of the packet via RF, they send proof they decrypted their layer of the packet back to the Challenger. The Challenger then bundles the receipts together and submits them to the consensus group to be rewarded in $HNT.
The role of the Challenger is similar to something like the role of a client in the @filecoin network. In that case, the client is asking a miner for proof that the file they are storing is still being stored.
In the case of Helium, the Challenger is asking the miners on the network to prove they are still creating network coverage that can be used by devices.

So we had to develop technologies like this to barely manage control over limited areas in Iraq's few urban centers. Only ~8 in 100 Iraqi adults owns a personal vehicle. That rate is > 1 car/adult in America yet I have never seen any doctrine paper or work of fiction address this


We've seen and struggled in civil conflicts with instant, local, universal, distributed communications (cell phone era, basically every conflict since 2000). We've seen and struggled in conflicts with instant, global, universal distributed communications (everything since 2011).

The world's most overfunded military and glow in the dark agencies struggle and largely fail to contain conflicts where fhe vast, vast majority of people are locked into a ~5mi radius of their home.

How can they possibly contain a conflict in a nation with universal car ownership and the most developed road network in the world? The average car can travel over 400 miles on one tank of gas, how can you contain the potential of that kind of mobility?

I think that's partially why the system was so freaked out by 1/6. Yes, most of it is histrionics but you don't decide to indefinitely turn your capital into the Baghdad Green Zone with fortifications and 25k troops over histrionics alone.
