Celestia Network is a modular blockchain and data availability layer that aims to simplify the development of decentralised applications by providing scalability and flexibility. Unlike traditional blockchains that bundle consensus and execution into a single layer, Celestia separates these functions, allowing developers to build more customised and efficient decentralised applications.

Celestia’s modular architecture offers developers the flexibility to create their own sovereign blockchains without the need to implement their own consensus mechanisms. This separation of consensus from execution allows for greater scalability and independence, as developers can focus solely on the application logic while relying on Celestia for data availability and security.

Celestia comprises several key components: the consensus layer, which handles the agreement on the state of the network; the data availability layer, which ensures that data necessary to validate transactions is available to all nodes; and the execution environment, which can be customized by developers to execute the specific logic of their decentralized applications.

By decoupling data availability from transaction execution, Celestia allows multiple execution chains to operate independently while still being anchored to a secure consensus layer. This means that execution chains can process transactions in parallel, significantly increasing throughput and reducing bottlenecks common in traditional blockchain systems.
