Celestia is a modular network that functions as a data availability and consensus layer for other blockchains.

Celestia is a blockchain platform built with Cosmos SDK and designed for customized blockchain creation. Its modular architecture separates the execution layer from the consensus and data availability layers, allowing developers to easily create or integrate networks with their own transaction execution mechanisms. This enables platforms with different execution engines to leverage Celestia’s consensus and security features while maintaining their unique properties.

Celestia uses a proof-of-stake consensus mechanism, with 100 initial validating nodes and staking delegation options. The platform’s data availability layer, featuring Data Availability Sampling (DAS) and Namespaced Merkle Trees (NMTs), distributes and verifies data across the network. This setup allows light nodes to verify block data efficiently, supporting network scaling.

Celestia also supports sovereign rollups, allowing rollup protocols to operate independently from the consensus and data availability layers. These rollups execute their own computation, akin to independent Layer 1 networks. Although not exclusive to rollups, Celestia’s architecture is designed to support a variety of rollup solutions.
