Appchains
Appchains are application-specific blockchains designed to run a single decentralized application (dApp) or a set of related applications, rather than hosting multiple apps on a general-purpose blockchain. They provide dedicated infrastructure with customizable consensus mechanisms, governance models, and execution environments tailored to the needs of a particular application. This approach aims to improve scalability, performance, and flexibility by isolating the app's operations from the broader network.
Developers should consider using appchains when building high-throughput dApps that require specialized features, such as custom transaction fees, privacy controls, or unique consensus rules, which are not feasible on shared blockchains like Ethereum. They are particularly useful for gaming, DeFi protocols, or enterprise solutions where performance and customization are critical, as they reduce congestion and allow for optimized resource allocation. Learning appchains is valuable for those working in blockchain ecosystems like Cosmos, Polkadot, or Avalanche, which support interoperable appchain architectures.
