The Aion Network is a multi-tier blockchain network designed to support a future where many blockchains exist to solve unique industry problems and to power the services of the modern world. Aion will become the common protocol used for these blockchains, enabling more efficient and decentralized systems to be built. The Aion protocol enables the development of a federated blockchain network, making it possible to seamlessly integrate dissimilar blockchain systems in a multi-tier hub-and-spoke model, similar to the internet.
