Celestia is a modular blockchain network designed for developers who need to launch and scale application-specific blockchains. It provides a foundational layer for consensus and data availability, allowing teams to focus on building execution environments without managing the underlying security of a full network.

• Modular Architecture: Separates the core functions of a blockchain into distinct layers. Celestia handles consensus and data availability, while execution is managed by separate rollups or chains.
• Data Availability Sampling: A cryptographic technique that allows light nodes to verify data availability without downloading entire blocks. This enables secure scaling while maintaining decentralization.
• Sovereign Rollups: Developers can deploy their own independent blockchains (sovereign rollups) that use Celestia for data and consensus. These rollups have full control over their upgrade paths and governance.
• Simplified Deployment: Reduces the complexity of launching a new blockchain. Teams do not need to bootstrap a validator set or create a new token for security, as they rely on Celestia's established network.
