Definition

Celestia is a modular blockchain network focused on data availability. It provides a base layer where block data can be published and made available for verification by other systems.

Why it matters

By separating data availability from execution, Celestia supports a modular architecture where rollups and other systems can specialize without carrying every responsibility in one monolithic chain.

Validator context

Celestia validators help operate this base layer. Their reliability, upgrade discipline, and security posture contribute to the trustworthiness of the data availability infrastructure.
