Aion is a smart contract platform created by Nuco in 2016 with the aim of addressing scalability, privacy and security issues found on other platforms.
Aion applications are written in Java enabling existing java developers to start creating decentralized applications without the need to learn new software such as solidity. Aion also hopes to act as a bridge between blockchains enabling buring and minting of tokens across different blockchains.
