Hosted on the Algorand blockchain, Planetwatch is an air quality project founded by ex-CERN manager Claudio Parrinello. Their utility token, Planets, facilitates all of the project’s transactions on the blockchain and can be earned in a similar way to HNT with Helium miners. Helium uses a “proof of coverage” model to provide connectivity to the internet of things network through the HNT token.
The miners have been extremely popular, with most out of stock since early 2021. Helium has a market cap of around $2.7 billion and sits just inside the top 50 crypto projects in the world. However, the Planetwatch project has a market cap of a meager $21 million.

The data is then shared for “consumers, special
