One of the most frequent questions asked by crypto skeptics is: What can you act
ually do with crypto, besides financial speculation and crimes? It’s a tough que
stion to answer, in part because most of the successful (and legal) uses of cryp
tocurrency so far have been in finance or finance-adjacent fields. There are ple
nty of crypto exchanges, nonfungible-token trading platforms and video games tha
t involve buying and selling crypto tokens. But so far, not many crypto projects
 have had what I’d call “normie utility” — solving problems that exist for peopl
e outside the crypto world, that aren’t primarily about buying or selling digita
l assets, and that would be impossible to solve with normal, noncrypto technolog
y.
Recently, though, I discovered one that does.
It’s called Helium. And while it’s not the most attention-grabbing crypto projec
t out there — no cartoon apes or copies of the Constitution are involved — tryin
g it out has helped me understand how crypto can be quite useful in solving cert
ain types of problems.
On a basic level, Helium is a decentralized wireless network for “internet of th
ings” devices, powered by cryptocurrency

On a basic level, Helium is a decentralized wireless network for “internet of th
ings” devices, powered by cryptocurrency.

   -The network is made up of devices called Helium hot spots, gadgets
   with antennas that can send small amounts of data over long distances
   using radio frequencies. These hot spots, which cost roughly $500
   apiece and can reach 200 times farther than conventional Wi-Fi hot
   spots, share their owners’ bandwidth with nearby internet-connected
   devices — like parking meters, air-quality sensors or smart kitchen
   appliances.

   Anyone can use the Helium network, although most of its users so far
   are companies like Lime (which has used Helium to keep tabs on its
   connected scooters) and the Victor mousetrap company (which uses it for
   a new line of internet-connected traps). More than 500,000 Helium hot
   spots are in use around the world, with thousands being added to the
   network every day.

Jim  Bell' comment:

This Helium network looks very interesting.  I foresee a time when in which a se
lf-selected person will be somewhere, ready to do something, at a moment's notic
e.  But he will want to take credit, somewhat anonymously, so he will prove his
entitlement to a large reward.

So, he will want to transmit a packet of data, encrypted and/or possibly hashed.
  The data might include latitude and longitude, time, nearby WiFi spectrum info
rmation.  Also may be included hashed video and audio information.

He will want to transmit this information, and he may want to wait until there i
s a return confirmation that the encrypted information has been published on a s
pecific website.
