Cardano (ADA) is a blockchain platform built on a proof-of-stake consensus protocol (called Ouroboros) that validates transactions without high energy costs. Development on Cardano uses the Haskell programming language, which is described as enabling Cardano “to pursue evidence-based development for unparalleled security and stability.” The blockchain’s native token, ADA, is named after the 19th century mathematician, Ada Lovelace.

Helium is a global, decentralized network enabling individuals to build and operate wireless infrastructure for mobile cellular traffic and the Internet of Things (IoT). Participants deploy Hotspots, plug-and-play devices that act as miniature cell towers, to provide coverage and earn rewards in HNT. The Helium Network offers a new approach to connectivity by distributing infrastructure ownership and incentivizing participation, creating a model that is more cost-effective and community-driven than the traditional telecom industry.
