Celestia is a modular blockchain network that aims to create a scalable data availability layer that will enable the next generation of scalable blockchain designs - modular blockchains. Celestia scales by detaching execution from consensus and introducing data availability sampling, a new primitive.
Celestia is distributing 60 million TIA to ecosystem users and developers. Users of the top ten Ethereum rollups, such as Arbitrum and Optimism, as well as Cosmos Hub and Osmosis stakers, and numerous public GitHub contributors, are eligible to get free TIA tokens.
