Helium network, which launched its mainnet in 2020, is a notable early example of a community-driven wireless network that rewarded its citizen-network-suppliers significantly while reducing costs and increasing accessibility for users (in certain geographies anyway). Its Helium Mobile offering, while still augmented by TMobile, continues gaining traction and was recently cited to have 335,000 subscribers. Many are also familiar with early decentralized storage networks such as Filecoin, Storj, and Arweave, which are becoming more essential to the advancement of AI due to their scalability, cost efficiency, and decentralization.
