TIA

Celestia (TIA) is a blockchain project that functions as a data availability network designed to enable developers to create custom blockchains with reduced complexity. Operating as a modular blockchain layer, Celestia separates the consensus and data availability functions from execution, allowing developers to build application-specific chains without implementing these critical components from scratch. The network utilizes a novel data availability sampling technique that allows light clients to verify that block data has been made available to the network without downloading entire blocks, significantly improving scalability. TIA serves as the native token of the Celestia network, used for securing the network through proof-of-stake consensus and paying transaction fees for data availability services. The project is notable within the blockchain developer community for pioneering the modular blockchain architecture concept, which enables horizontal scalability by decoupling different blockchain layers and allowing specialized optimization for each function. This approach has gained significant attention from developers and researchers seeking alternatives to traditional monolithic blockchain designs that attempt to handle consensus, execution, and data availability simultaneously.
