Ardor is a “full blockchain-as-a-service” multi-chain platform that evolved from the time-tested Nxt blockchain. The mainnet went live on 01 January 2018. The unique parent-child chain architecture of Ardor, with a single security chain providing energy-efficient proof of stake consensus for multiple transactional “child chains,” enables three fundamental advantages – reduced blockchain bloat, increased scalability, and the ability to launch and host ready-to-use interconnected blockchains.
Ignis is Ardor’s first public, permissionless, and fully featured child chain maintained by Jelurida, the corporate entity responsible for the development of the Ardor and Nxt platforms. The features and functionality available on Nxt were implemented on Ignis – along with new features such as lightweight contracts, account and asset controls, and composite phased transactions. Businesses can launch apps and services using the features available on the Ignis child chain such as issuing and trading digital assets, launching voting systems, and leveraging distributed cloud storage.
Multiple additional child chains can be created on the Ardor platform for various organizations, such as public entities, enterprises, consortiums, research institutions, and financial service providers who wish to customize the features available to their child chain end-users. The platform’s technological innovations make it possible for large corporations and SMEs to have a child chain with ready-to-use features and a distributed security network, instead of creating their own network of nodes to support a blockchain and developing features from scratch. Child chains can be implemented in a cost-effective way without compromising their security, which is guaranteed through transaction “bundlers” connecting child chains to the parent Ardor chain.”Jelurida ardor Whitepaper
