Ardor(ARDR)

What Is Ardor?#

Ardor is a blockchain-as-a-service platform that uses a parent-child chain architecture to let businesses and developers create their own blockchains without building from scratch. The parent chain (Ardor) handles security and consensus, while child chains handle specific business applications. Each child chain can have its own tokens, rules, and features while sharing the parent chain's security.

Think of Ardor like a shopping centre. The building itself (the parent chain) provides the structure, security, and utilities. Individual shops (child chains) operate independently within it, each with their own products and customers.

The Problem It Solves#

As a blockchain grows, its database (the ledger of all transactions ever made) gets larger and larger — a problem called "blockchain bloat." This makes running a node increasingly expensive and slow. Additionally, creating a new blockchain from scratch requires enormous technical effort and the challenge of building a secure validator network. Ardor solves both problems: child chains can periodically prune old transaction data, and they inherit the parent chain's security without needing their own validators.

How It Works#

The Ardor parent chain runs on a Proof of Stake consensus mechanism using the ARDR token. Validators (called forgers) stake ARDR to participate in block creation and earn rewards. Child chains process their own transactions and maintain their own token economies, but the transaction records are ultimately secured by the parent chain.

Child chains benefit from built-in features like asset issuance, a decentralised marketplace, voting systems, and messaging — all available out of the box without custom development.

Why It Matters#

Ardor's parent-child architecture was one of the early solutions to blockchain scalability and bloat. While Polkadot uses parachains and Avalanche uses subnets to achieve similar multi-chain goals, Ardor was among the first to implement this concept. Its ready-made features make it particularly suited for businesses that want blockchain capabilities without a large development team.

Ardor Introduction#

Ardor is a blockchain-as-a-service platform designed to tackle some of the persistent issues within existing blockchain systems, such as blockchain bloat and the need for multiple transactional tokens. Ardor's innovation lies in its unique parent-child chain architecture, which enables a single security chain and multiple transactional chains. This structure allows for a reduction in blockchain bloat and provides a versatile ecosystem for various organizations to create their own interconnected blockchains without compromising security. The project aims to propel blockchain technology forward by providing a scalable, secure, and flexible solution for businesses and developers alike.

Description: What Does Ardor Do?

Ardor is a blockchain-as-a-service platform that evolved from the Nxt blockchain. It aims to address major scalability and usability issues in the blockchain space through an innovative parent-child chain architecture. The project’s main goals include reducing blockchain bloat, enabling multiple transactional tokens, and providing ready-to-use interconnected blockchains for organizations.

Ardor achieves its objectives through a unique architecture where the parent chain (Ardor) ensures security, while multiple child chains handle various transactional activities. This setup allows for features like customizable child chains with their own native tokens, thus providing a versatile and scalable blockchain solution.

Problem: Why Ardor Is Being Developed?

The primary problem Ardor aims to solve is blockchain bloat, a condition where the blockchain becomes increasingly large and difficult to manage over time. This issue impacts the efficiency and scalability of blockchain systems. It also aims to simplify the creation and management of blockchain applications for businesses and developers.

Existing solutions often require businesses to create their own blockchains from scratch, which can be cumbersome and resource-intensive. Ardor’s architecture allows for the deployment of multiple child chains that can be pruned and managed efficiently without compromising security, thus addressing the limitations of current solutions.

Use Cases#

• Customizable Child Chains: Organizations can create child chains with specific functionalities tailored to their needs.
• Decentralized Foreign Exchange: Child chains can be pegged to fiat currencies or other cryptocurrencies, enabling decentralized forex trading.
• Crowdsales and Token Distribution: The platform can be used for conducting token sales and distributing tokens in a secure and transparent manner.

How Does Ardor Work?#

Ardor operates through a parent-child chain architecture. The parent chain, Ardor, provides security and handles the consensus mechanism, while the child chains handle various transactional activities. Each child chain has its own native token and can be customized to meet specific requirements of different organizations.

1. Components:

   • Parent Chain (Ardor): Ensures security and handles the consensus mechanism.
   • Child Chains: Handle transactional activities and can be customized.

2. Operation:

   1. Transactions are initiated on a child chain.
   2. Child chain transactions are bundled into blocks.
   3. These blocks are then linked to the parent chain through a special ChildChainBlock transaction.
   4. The parent chain ensures the security and validation of these child chain transactions.
   5. Any unnecessary data from child chains can be pruned to reduce bloat, while the parent chain maintains a secure and immutable record.

Technical Details#

Ardor utilizes a Proof-of-Stake (PoS) consensus mechanism similar to its predecessor, Nxt. The platform features a unique parent-child chain structure where the parent chain provides security, and child chains handle specific transactions.

• Blockchain: Parent-child chain structure
• Consensus Mechanism: Proof-of-Stake (PoS)

1. Novel Technologies:
   • Pruning: Removal of unnecessary data from child chains to maintain a lightweight blockchain.
   • ChildChainBlock Transactions: Special transaction types that link child chain blocks to the parent chain.
   • Bundlers: Entities that bundle child chain transactions and pay fees in the parent chain’s token (ARDR).

Ardor Tokenomics: Token Utility & Distribution#

Ardor’s ecosystem uses multiple tokens, primarily the ARDR token for the parent chain and various native tokens for child chains.

The ARDR token is used within the ecosystem to secure the network through the PoS mechanism, pay transaction fees, and facilitate interactions between child chains. Child chain tokens are used for specific transactions within their respective chains.

The IGNIS token, for example, is the native token for the first unrestricted child chain, Ignis. The distribution strategy for IGNIS included a crowdsale and airdrop to NXT holders.

Key Ardor Characteristics#

Ardor embodies several core blockchain characteristics:

• Decentralization: Employs a PoS mechanism to ensure decentralized security.
