Helium is a decentralized, open wireless network built on a new blockchain for the physical world. It relies on a novel type of work called Proof of Coverage, and a new consensus algorithm (based on HoneyBadger BFT). The Helium Network is used to route data for long range, lower power devices (often called "IoT" devices).

Proof-of-stake offers to lower the unnecessary risks posed by the proof-of-work system. It opens up the opportunity for more people to become validators and to keep the network more decentralised . The biggest capital investment a validator would need to make is a standard-quality computer, a reliable Internet connection, and 90% less electricity than what traditional miners would require.

What is Proof of Work. Visualize and Download High-Resolution Infographic. A proof of work is a piece of data which was difficult (costly, time-consuming) to produce so as to satisfy certain requirements. It must be trivial to check whether data satisfies said requirements. Producing a proof of work can be a random process with low probability, so that a lot of trial and error is required on average before a valid proof of work is generated.
