Ignis Smart contract Ardor child chain

Ignis is the public and permissionless core child chain of the Ardor platform. Ignis enables anyone to deploy lightweight smart contracts in Java and automate on-off chain business processes using a library of more than 250+ APIs. Application and service end-users never need to directly interact with the blockchain because the “bundling” system allows businesses and dapp owners to sponsor transaction validation fees for their users. The project is maintained by the developers at Jelurida and receives frequent feature upgrades.

Technology

The advanced features and functionality available on the time-tested Nxt blockchain were implemented on the public and permissionless Ignis child chain when it launched as the core child chain of the Ardor platform on 01 January 2018. Ignis offers lightweight smart contracts coded in Java and 250+ APIs, making it simple for anyone to tokenize supply chains, launch dApps, manage KYC/AML compliant STOs, and run blockchain based services that interface seamlessly with off-chain databases.

Ignis transactions are “bundled” and validated by the Ardor parent chain’s energy efficient proof of stake consensus. Bundlers can be run by anyone and they are nodes that collect transaction fees in the native child chain token, IGNIS, while paying with ARDR tokens to send the child chain transactions for validation on the parent chain. Five custom bundler templates are built-in to the platform to enable app and service owners to sponsor the transaction fees for only their intended end-users, eliminating the need for users to directly interface with the blockchain. Ignis is interoperable with all other child chains on the Ardor platform.

The Ignis chain offers powerful features such as issuing and trading digital assets and nonfungible tokens (NFTs) on the built-in decentralized exchange, launching voting systems, app creation through arbitrary messaging, sending private transactions, and a data cloud. The potential use cases of these features are further expanded by revolutionary offerings such as secure transaction vouchers, account and asset controls, asset properties, and composite phased transactions.
