Ardor (ARDR)

From CryptoWiki

Ticker symbolARDR
Consensus mechanismPlatform, blockchain for spawning blockchains



  • Split off from NXT, built on top of NXT tech.

"Ardor is operated by Jelurida and has its roots in the Nxt blockchain, which was one of the first PoS networks and has been running since 2013. Ardor was created by the same team to overcome the adoption challenges of traditional linear blockchain architecture. These include the use of a single token, a lack of customization capability, and blockchain bloating as a result of processing and storing every single transaction in the same way. 

Ardor aims to overcome this with an architecture that comprises the main parent chain and child chains. Each child chain is entirely customizable according to user requirements and can use its own token. Ardor also makes use of stateless, lightweight smart contracts programmed in Java."

How it works

“The contract code itself is a simple Java class uploaded to the blockchain and therefore digitally signed and time stamped. However, the execution of the contract is only performed by nodes who choose to run the Contract Runner addon. This removes the need for ‘metered’ execution using the gas model and removes the risk of systematic failure in case the contract malfunctions. Furthermore, this enables contracts to work as oracles, to freely integrate with external systems and thus removes the need for a separate layer of oracles.”

Projects that use or built on it

"Applications running on Ardor include augmented reality game Triffic, art-focused DAO Tarasca, and real estate management platform Dominium."


From this [[]]:

“Ignis will be the first child chain on Ardor. Think of Ardor as this giant mechanical robot torso and head. It has everything needed for processing but doesn't really have a lot of features beyond processing, and maybe transferring some data around itself. (There will be almost no features on the Ardor main chain and just the ability to transfer ARDR and forge) Child chains are like the limbs that can be attached to this robot. They can do all the cool things while being powered by the robot torso and head.

With Ardor, there can be multiple child chains. So, if one wants their own blockchain without the problems of having enough nodes, etc., then creating a child chain would be an ideal option. Transaction fees will be paid in the child chain token and not in ARDR, though each child chain will need a bundler in order to collect these fees and pay the main chain in ARDR for processing the bundled transactions.”

"The first and main child chain of Ardor is Ignis, which offers unique features and functions across other child chains operating on the Ardor network. These include asset issuance and user account configuration. Ignis also provides various on-chain features, including a voting system, exchange, and data cloud. Ardor and Ignis each operate their own tokens, under the tickers ARDR and IGNIS, respectively."

Pros and Cons




"Ardor runs on a parent and child chain structure, which offers improved throughput compared with a linear blockchain like Bitcoin or Ethereum. This structure can be compared to Ethereum 2.0’s sharding mechanism, where Ethereum’s Beacon Chain will have sharded chains operating as substructures in parallel with one another.

However, Ardor launched with another critical feature built in that is often overlooked by blockchain core developers: Ardor child-chain operators can issue their own native tokens, which are compatible with the parent chain."
