Ardor is a blockchain-as-a-service platform that will allow people to utilize the blockchain technology of Nxt through the use of child chains. Since all processing will be done on the Ardor main chain, child chain creators won’t need to worry about common issues when creating a blockchain as well as securing it with enough nodes. Child chains will be able to utilize features currently seen in Nxt such as decentralized phasing, voting, and trading, as well as be able to interact with other child chains on the platform, including IGNIS, the first child chain to be launched.
The Jelurida developers have identified an elegant solution that allows addressing the above limitations of the current Nxt software, while building upon existing design and code, and reusing the time-tested platform features without having to re-implement them. The architecture of the next generation Nxt platform - Nxt 2.0, now known as "Ardor", takes the system further, provides scalability, makes it even more flexible, yet preserves its security and stability. The fundamental concept of the Ardor design is a clean separation between "forging token" and "transactional token". In Nxt, it is the NXT coin that serves this dual purpose, being used both to determine forging stake, i.e. the right of an account to generate blocks, and to execute all kinds of value-transfer transactions, i.e. represent unit of value. In Ardor, a separation of these two functions is used to achieve both much greater scalability, by reducing blockchain bloat, and flexibility, by allowing multiple other transactional tokens to be used, in effect allowing custom "child chains" to exist and run on the same network of nodes.
