A specialized blockchain for applications or an Appchain is a blockchain built specifically for a particular application. Unlike public blockchains that support multiple applications, Appchains are optimized for single-use cases — ensuring efficient performance tailored to the needs of that application. The concept of Appchain was introduced by Cosmos and Polkadot in 2016. In theory, Bitcoin could be considered an Appchain for digital gold.

Appchains allow developers to customize the blockchain environment to suit their specific needs. This narrower focus enables developers to overcome common challenges faced by multi-application platforms, opening up innovation opportunities without compromising with other underlying blockchain platforms.

What are the advantages of using Appchains?

Typically, attempting to provide full scalability in traditional blockchains can lead to systemic vulnerabilities. Thus, Appchains are devised to address these risks. Appchains grant autonomy to protocols. This autonomy ensures that applications and protocols do not face issues propagated from the main blockchain. Furthermore, most protocols are better suited to autonomous operation, enabling them to function independently without being constrained by a larger ecosystem.

So, what are the benefits of building on Appchains?

1. Optimal Performance:

  • Appchains are optimized for specific use cases, ensuring the highest performance for your applications without sharing resources with other applications.

2. High Customizability:

  • Developers can customize blockchain parameters such as consensus mechanisms, governance models, and token standards to fit the specific requirements of the application.

3. Enhanced Security:

  • With a separate blockchain environment, Appchains minimize security risks associated with sharing the network with multiple applications.

4. Scalability:

  • Appchains allow scaling according to the specific needs of the application without being limited by other factors on the public blockchain.

5. Autonomy and Control:

  • Protocols and applications on Appchains can operate independently, minimizing dependencies and influences from other blockchains.

6. Interoperability:

  • Despite operating independently, Appchains can still interact with other blockchains through general messaging systems and interaction protocols.

How do Appchains work?

Appchains operate by creating custom blockchain environments designed specifically for particular applications or protocols. Each Appchain operates separately from the main blockchain (such as Ethereum). This separation ensures that transactions and smart contracts related to a specific dApp are processed independently within the Appchain.

The native tokens of Appchains can serve various purposes, including being used for gas fees to compensate validators protecting the network. Appchains also operate with a general messaging system, enhancing interaction between chains, increasing the utility and flexibility of dApps. Developers can customize dApp parameters such as selecting consensus mechanisms, governance models, token standards, and many other factors.

Utilizing Appchains not only resolves issues regarding performance and security but also opens up new opportunities for development and innovation in the blockchain field.
