Celestia

Celestia is a modular consensus and data network built to enable anyone to deploy their own blockchain with minimal overhead easily. Celestia addresses the blockchain scalability trilemma by separating the consensus process from the execution layer. Instead of combining everything on the blockchain, Celestia provides a modular design in which the Consensus and Data Availability Levels are isolated from the Execution Layer. With Celestia's modular architecture, developers can easily define their own virtual execution environments. Additionally, each application gets its own execution space while inheriting the securities of Celestia's consensus. Finally, applications can be updated without main chain hard forks. Furthermore, Celestia offers high scalability for Web3 applications, flexibility to customize applications, and reduces the cost of deploying and maintaining your own blockchain.
