Ardor

What is Ardor?

Ardor presents a multichain blockchain platform featuring a distinctive parent-child chain structure. The overall network security is ensured by the parent Ardor chain, while the interoperable child chains boast extensive functionality. This sophisticated design, coupled with hybrid user permissioning capabilities, is pivotal in providing the flexibility required for diverse use cases, ultimately paving the way for the widespread acceptance of blockchain technology. Furthermore, Ardor is crafted with scalability as a primary consideration, addressing prevalent industry challenges such as blockchain bloat, reliance on a single token, and the demand for easily customizable yet compatible blockchain solutions.

How Ardor Works

In the Ardor Platform, the traditional single blockchain model is replaced by a combination of a forging chain, denominated in the Ardor token, and multiple child chains, each with its own transactional token. The forging chain handles specific transaction types, including Ardor transfers, trading between Ardor and child chain tokens, leasing Ardor balances for forging, and special "ChildChainBlock" transactions. The forging power is determined by the Ardor balance, maintaining the consensus model from the Nxt platform.

Transactions modifying Ardor balances are recorded on the forging chain, ensuring proof-of-stake security. However, transactions altering child chain token balances or other account holdings are recorded only on their respective child chains. Pruning these child chain transactions does not compromise blockchain security, as Ardor account balances can be verified trustlessly by each node.

Child-chain transactions are anchored to the forging chain using ChildChainBlock transactions, which include a list of child chain transactions affecting account balances. While no actual forging occurs on child chains, the cryptographic hash linking enables signature verification even after pruning.

Nodes validate transactions from all child chains, and while a node downloading the blockchain cannot fully validate pruned child chain transactions, overall blockchain security remains intact. Nodes process transactions from all chains, storing child chain transactions for the last 1440 blocks until their expiration or phasing finish height, depending on which is longer. Nodes not configured for longer archiving prune child chain transactions, but archival nodes can choose to store one or more child chains for an extended or indefinite period.

Advantages of Ardor

Ardor's architecture offers three fundamental advantages:

1. Each child chain possesses its own native tokens, serving as a unit of value and for transaction fee payments, along with a range of readily available features.
2. Scalability is achieved through the pruning of unnecessary data from child chains once they are incorporated into the permissionless Ardor parent chain, preventing network "bloat."
3. All child chains are interconnected, sharing the same source code to ensure ecosystem interoperability. This enables fully decentralized trading of child chain tokens and allows transactions on one child chain to access data or entities on another.

Moreover, all child chain transactions are included in the parent Ardor chain through the bundling system. This process groups multiple child chain transactions into parent chain blocks, allowing application owners to sponsor transaction fees for their end users.

Ardor employs a 100% pure proof-of-stake consensus algorithm, contributing to its energy efficiency and significantly reducing the hardware requirements for network security. The Ardor parent chain token, ARDR, is utilized for forging— the generation of new blocks and network consensus. Forgers of ARDR receive transaction fees from the blocks they forge, but no new ARDR coins are created.

Ardor Team Background

Ardor is deceloped by Jelurida, a Swiss blockchain software development company. The company was initially incorporated in the Netherlands in 2016 with the objective to further develop and maintain the Nxt and Ardor blockchain platforms. The primary goal was to ensure the sustainability and longevity of both projects and explore commercial opportunities by providing public, private, and hybrid blockchain solutions.

In 2017, Jelurida moved its main operations to Switzerland and expanded internationally. The company has established a presence in many countries spread over three continents, including Spain, Israel, the Netherlands, Bulgaria, and South Korea. Jelurida has experienced growth in its team, achieved milestones on its development roadmap, and continued to expand its partner and client base.
