The Ardor Main Chain will be where all Ardor tokens ARDR will reside. It will serve as the system that secures all child chains and processes their transactions.
Ardor is a blockchain-as-a-service-platform that evolved from the time-tested Nxt blockchain. It launched on January 1, 2018 after a successful year on testnet. The unique parent-child chain architecture of Ardor, with a single security chain and multiple transactional chains, offers three advantages: reducing blockchain bloat, providing multiple transactional tokens, and hosting ready-to-use interconnected blockchains called child chains.
