Celestia is a modular data availability network built with the Cosmos SDK. Celestia’s unique architecture offers developers a platform to build highly scalable decentralized applications and rollups. As Celestia directly provides the data availability and consensus layer, and Optimint provides the settlement layer, developers only have to focus on building the execution layer. TIA is the native token of Celestia, and can be used for gas fee payment, network governance, and staking participation.
