One of the latest innovations in blockchain is the concept of application-specific blockchains, also referred to as appchains. Appchains bring customization and efficiency to blockchains. But what exactly is an appchain, and how does it work?
Read on as we explore appchains, their benefits and drawbacks, make comparisons, and discover some of the leading appchains.
What Are Appchains?
Appchains are specialized blockchains built for a specific use. Unlike broad-use blockchains that aim to support various applications, appchains are crafted to serve the distinct needs of individual applications.
Because appchains are built for a particular use, their architecture can be tailored to satisfy precise business needs. This design boosts performance and effectiveness in operation, ensuring smooth integration with workflow systems meant for use by such applications.
Focusing on a specific use case means that appchains have better efficiency, alleviate network congestion and lower transaction costs than their general-purpose counterparts. They also excel in managing large transaction volumes and handling specialized data types, making them optimal for niche applications.
How Do Appchains Work?
Appchains work on the basic principles of blockchain but are created to address the requirements of individual applications. Each appchain allocates resources to the selected task, ensuring efficient utilization without dispersing efforts across unrelated applications.
Appchains can adopt different consensus mechanisms, such as Proof-of-Work (PoW) or Proof-of-Stake (PoS), to meet each application's specific needs. Smart contracts within appchains are also tailored to each appchain's precise requirements.
Full-fledged appchains typically consist of five layers:
Appchains usually work on top of other main blockchains like Ethereum. Still, they are independent, often connected to Layer 0 protocols such as Cosmos. Layer 0 serves as a foundational network, providing interoperability and infrastructure, enabling multiple Layer 1 appchains to coexist and interact within a broader ecosystem.
Examples of Leading Appchains
As the concept of appchains grows, a growing number of appchains are being introduced. Here are some of the leading appchains.
Cosmos Zones
Cosmos zones function as standalone blockchains connected to the Cosmos Hub, analogous to appchains within the Cosmos ecosystem. These zones utilize the Inter-Blockchain Communication (IBC) protocol, allowing seamless data transfer across the network.
Avalanche Subnets
Avalanche subnets are independent blockchains within the Avalanche network that facilitate the creation of application-specific blockchains. Each subnet is supported by a unique set of validators responsible for achieving consensus on the state of associated blockchains.
Polkadot Parachains
Polkadot's parachains are individual blockchains that operate side by side within the Polkadot ecosystem. Each parachain is linked to the main Relay Chain and equipped with its tokenomics, governance models, and functionalities, allowing them to be customized for different uses.
Benefits and Drawbacks of Appchains
While appchains have a lot of benefits, such as scalability and interoperability, they still present some drawbacks.
Benefits
Drawbacks
Resource-intense: Developing an appchain can be resource-intensive, potentially deterring developers or organizations with limited resources from pursuing appchain development.
