what's Ardor?

Ardor is a blockchain-as-a-service platform designed to enable the creation of customizable child chains that inherit the security and infrastructure of a main parent chain. Developed by Jelurida as an evolution of the Nxt blockchain, Ardor addresses scalability issues by allowing businesses and developers to launch independent blockchains for specific applications, such as supply chain tracking or digital asset management, without the overhead of maintaining a full network. The platform operates on a proof-of-stake consensus where ARDR tokens secure the parent chain through forging, while child chains process transactions in bundles to the parent for finality, preventing blockchain bloat. Features include native tokenization for child chain currencies, lightweight smart contracts for automation, and interoperability tools, making it suitable for enterprise use cases requiring regulatory compliance and efficiency.
