Definition
Celestia is a modular blockchain protocol and native asset that provides data availability and consensus as standalone base-layer services for other chains. It separates transaction execution from ordering and data publishing, enabling external rollups and sovereign chains to post their data to Celestia’s blobspace while maintaining their own execution environments and state transition rules. The Celestia token coordinates economic security, fee payment, and protocol incentives.
In Simple Terms
Celestia is a blockchain that focuses on ordering and publishing transaction data for other blockchains instead of executing their transactions itself. It offers a shared data layer, called blobspace, that rollups and other chains use to store their data securely, while the Celestia token is used for fees and economic alignment within the protocol.
Context and Usage
Celestia is discussed in the context of modular blockchain architectures, where execution, settlement, and data availability are decoupled into distinct layers. It is referenced when describing how rollups and other chains outsource data availability and consensus to a specialized base layer. The term appears in technical discussions about scaling, data availability guarantees, and the design of node roles in modular ecosystems.
