What are Appchains?
An appchain, or application-specific blockchain, is a specialized blockchain designed for a singular application. This concept was introduced by Cosmos and Polkadot in 2016 and aims to address the limitations of generalized blockchains like Ethereum.
Unlike public blockchains that handle multiple applications, appchains are optimized for specific use cases, ensuring tailored performance, scalability, and efficiency. This customization is particularly beneficial in avoiding the common pitfalls of traditional blockchains, such as network congestion and high gas fees.
How do Appchains work?
Appchains create customized blockchain environments tailored for specific applications. Transactions and smart contracts related to a particular decentralized application (dApp) are processed independently within the appchain. These chains can use native tokens for multiple purposes, including paying validators who secure the network. A generalized messaging system facilitates interoperability between chains, enhancing the utility and flexibility of dApps.
How architecture of an Appchain
The architecture of an appchain typically consists of several distinct layers, each serving a specific function to support the overall system. These layers include:
Smart Contract Layer: Handles the execution and management of smart contracts, which are self-executing contracts with the terms of the agreement directly written into code.
Consensus Layer: Implements the mechanism through which nodes agree on the state of the blockchain, ensuring consistency and reliability of the data.
Data Layer: Deals with the storage and retrieval of data, including transactions and blockchain state.
Application Layer: The topmost layer where the actual application logic resides, interacting with smart contracts and providing user interfaces or APIs for end-users.
Network Layer: Manages the peer-to-peer networking, allowing nodes to communicate and synchronize their data.
Benefits of Appchains
Sovereignty: Appchains operate independently, reducing the risk of cascading failures from issues in the main blockchain.
Customization: They allow for tailored designs to meet specific application needs, such as choosing the consensus mechanism and governance model.
Increased Efficiency: Dedicated resources lead to faster transaction speeds and reduced bottlenecks.
Cost-Effective: Without competition for block space, appchains avoid gas fee spikes.
Scalability: They can handle more users and transactions as the application grows.
Building on Appchains
Building on an appchain involves selecting the appropriate framework based on the application’s primary function. For blockchain games, networks like Ronin or Arbitrum’s Xai Network are optimal, while DeFi applications might prefer Cosmos SDKs or Polkadot Parachains. Developing smart contracts, the backbone of any dApp, can be streamlined using libraries like thirdweb’s smart contract templates and other developer tools.
Here are some notable and current Appchain projects:
dYdX v4: This decentralized exchange operates on a fully sovereign, open-source blockchain, built using the Cosmos SDK, allowing for full control over consensus and transaction types.
Axie Infinity: A play-to-earn game operating on the Ronin chain, addressing high gas fees on Ethereum.
DeFi Kingdoms: A web3 game on the DFK Chain, an Avalanche subnet, aiming to become the gaming appchain for community members and projects.
