"The Aion blockchain network is like a computer network that makes it possible for dissimilar systems to communicate.
The Aion network will pass logic and value among participating blockchains as freely as liquid assets, where every transaction occurs without centralized intermediaries.
The Aion network will be centered on a public, purpose-built third-generation blockchain called Aion-1. Designed to connect other blockchains and manage its own robust applications, Aion-1 also provides the crypto-economic system that incentivizes interoperability in the ecosystem."
https://aion.network/The AION network token will be the fundamental method of interaction within the Aion network. Within Aion-1, the token will enable users to develop applications, connect blockchains, and participate in consensus; while providing the crypto-economic system to ensure a well-adopted decentralized ecosystem.

scheduled for October 3, 2017 - 1400 UTC.
