App-specific blockchains remain a promising solution for scalability By Cointelegraph



App-specific blockchains, or appchains, are specifically designed to support the creation and deployment of decentralized applications (DApps). In an appchain, each app runs on its separate blockchain, linked to the main chain. This allows for greater scalability and flexibility, as each app can be customized and optimized for its specific use case.

Appchains are also an alternative solution for scalability to modular blockchains or layer-2 protocols. Appchains present similar characteristics to modular blockchains, as it is a type of blockchain architecture that separates the data, transaction processing and consensus processing elements into distinct modules that can be combined in various ways. These can be thought of as “pluggable modules” that can be swapped out or combined depending on the use case.

Scalability is one aspect of the blockchain trilemma facing developers.
