Frequently Asked Questions

Here are some common questions and answers about Aion. If your question isn’t included, ask us on Discord


Aion is a common protocol for blockchain interoperability. Among other things, it will enable any private or public blockchain to federate, scale, and spoke. For more information, see our Executive Summary.
Aion is a community-driven project lead by Nuco Global Inc. (, the founding company, and the Aion Foundation.

About the Aion Protocol and Aion-1 Network

As it relates to Aion: To federate is to send data and value between any AION compliant blockchain and Ethereum. To scale is to provide fast transaction processing and increased data capacity to all AION compliant blockchains. To spoke is to allow for the creation of customized public and private blockchains that maintain interoperability with other blockchains, but allow publishers to choose governance, consensus mechanisms, issuance, and participation. For more information, see our White Paper.
The Aion-1 blockchain is the genesis implementation of the connecting network. It is designed to be a fair, distributed, open blockchain architecture that is capable of fulfilling the requirements specified in the multi-tier blockchain network architecture. As an open blockchain, Aion-1 was designed with the following goals:
  • Connecting blockchains and external services (e.g., oracles and databases) together through the contiguous network and providing accountable communication maintained through a decentralized network.
  • Providing the necessary infrastructure to develop high-performance, decentralized, inter-blockchain applications.
  • Creating a maintainable network through a robust and sustainable economic model. Users will be able to deploy adjacent participating networks suitable for their own use cases and communicate with other networks through an accountable routing architecture.
Users ranging from large enterprises hosting consortium networks to community-oriented open networks are all welcome to participate. In the future, decentralized applications could sit on top of the connecting network with logic driven by integrating data from a multitude of blockchain networks. In addition, the Aion-1 blockchain is equipped with a full-functioning economic system intended to drive the continued maintenance and integrity of the network. For more information, see our White Paper.
A bridge is a communication protocol that facilitates communication between the participating network and the connecting network. A bridge is composed of its own distinct network of validators that assures translation of protocols and accountability between networks. Bridges are directional; the source blockchain is the chain where transactions are emitted and the target blockchain is the chain where the transactions are forwarded. A bridge has two main responsibilities:
  • Signing and broadcasting an interchain transaction only if they have been sealed in the source blockchain and an interchain transaction forwarding fee has been paid.
  • Informing the connecting network of the merkle hash updates of the participating network.
For more information, see our White Paper.
Aion-compliant blockchains refer to the participating blockchains that comply with the Aion protocol and on which bridges can be established easily to forward interchain transactions through Aion-1. To be Aion-compliant, a blockchain must meet certain requirements including:
  • Be decentralized in some fashion and support procedures commonly found in blockchains such as atomic broadcast and transactions. The exact implementation is left to the discretion of the bridging protocol and the network itself.
  • Be able to recognize interchain transactions as distinct from regular transactions.
  • Be aware of the consensus protocol used by the bridge and store a transaction deemed valid.
  • Implement locktime or a similar feature that allows tokens to be held by the network for a period of time.
Blockchain vendors will be able to adapt their offerings to be Aion-compliant. The Nuco blockchain infrastructure will be among the first Aion-compliant networks. For more information, see our White Paper.

About the Aion Token and Token Distribution

AION network tokens are the fuel used to create new blockchains, monetize inter-chain bridges, and secure the overall network. For more information, see our White Paper.
The AION network token sale will be executed in three phases, each offering a unique set of benefits to various investor profiles. Private Sale
  • Mid 2017
  • 30 million tokens sold
  • Targeted to institutional and accredited investors
  • October 3rd, 2017 - UTC 1400
  • 15 million USD soft cap + 4 hour time cap
  • Limited token generation event
Public Sale
  • TBA
  • 5x sum of tokens sold in the Private Sale and Pre-Sale
For more information, see our Token Sale Mechanics page.
In order to ensure the highest level of security, the AION network token sale will be conducted on the Ethereum blockchain. The only accepted contribution method will therefore be Ether. We do provide Shapeshift integration to streamline the process of converting any other cryptocurrency to Ether. At the start of the Pre Sale, we will post the Ether addresses where contributions can be made using an ERC-20 enabled Ethereum wallet. At the close of the Pre Sale, tokens will be allocated to the accounts from which the contributions were made. For more information, see our Token Pre-Sale page.
Purchased AION network tokens will be distributed at the close of the Pre-Sale. For more information, see our Token Pre-Sale page.
Pre-Sale contributors will be provided with the choice of either receiving their allocated tokens immediately or according to a one-year token release schedule (TRS). Any purchased tokens can be contributed to the TRS at any point prior to the TRS lock date, ahead of the Public Sale. Immediate Token Release At the moment of minting (following the close of the Pre-Sale), purchased tokens are distributed immediately to contributors’ wallets. Token Release Schedule Purchased tokens can be set to follow a release schedule at the time of purchase or any time prior to the TRS lock date. At the close of the Public Sale, 25% of tokens in the TRS will be distributed to contributors’ wallets, with the remaining tokens being distributed monthly for one year. For more information, see our Token Sale Mechanics page.
