What is an application-specific blockchain (AppChain)?

• AppChains, or application-specific blockchains, are designed to meet the unique requirements of a particular use case or business need.

• Unlike general-purpose blockchains, AppChains are optimized for specific functions, striving for more efficient processing, reduced congestion, and lower transaction costs.

• AppChains present a nimble and targeted approach, built precisely for the needs of the protocol they are built for, aiming for more efficient processing, reduced congestion, and lower transaction costs.

An AppChain, short for "application-specific blockchain," is a tailored solution specifically designed to meet unique task requirements of a decentralized application or web3 protocol.

Unlike multi-purpose blockchains that strive to be a one-size-fits-all solution, AppChains can be finely tuned to the specific performance, security, and governance needs of an application.

This specialization seeks to allow for more efficient processing, reduced congestion, and lower transaction costs, making AppChains a suitable choice for applications requiring high throughput, security, or unique functionality.

AppChains function by creating their customized blockchain environments, tailored for specific applications. They operate independently, reducing the risk of cascading failures from other systems. This independence also allows for tailored designs to meet specific application needs, leading to increased efficiency.

Dedicated resources also mean faster transaction speeds and reduced bottlenecks. Without the competition for block space, AppChains may potentially avoid gas fee spikes. As the application grows, dedicated resources can handle more users and transactions.

AppChains provide sovereignty to protocols, ensuring apps and protocol don’t face cascading failures of the main blockchain. Most protocols are more suited to sovereign operations, allowing them to operate independently without the constraints of a larger ecosystem. This narrow focus allows developers to eliminate common challenges faced on multi-app platforms, facilitating innovation within the given parameters.

AppChains differ from other types of blockchains in several ways.

Unlike monolithic chains, which are designed to handle a wide range of applications, AppChains are optimized for a specific function. This aims to make them more efficient and less congested than general chains.

Compared to modular chains, which are made up of interchangeable parts, AppChains are built for efficiency around specific tasks.

Finally, unlike Layer-2 chains, which are built on top of existing blockchains to improve scalability, AppChains can operate independently.

Several AppChains have emerged in recent years. For example, Osmosis is an AppChain that strives to provide a high-performance, customizable environment for DeFi applications, and Litentry is another AppChain that focuses on decentralized identity solutions.

These AppChains illustrate the diverse range of applications that can benefit from the specialized environments provided by AppChains.
