Celestia, conceived by founders Ismail Khoffi and Mustafa Al-Bassam, is a modular data availability network designed to scale securely with its growing user base, facilitating the creation of individual blockchains. Its approach decouples execution from consensus and employs data availability sampling. The latter ensures data authenticity by allowing light nodes to sample random data chunks from each block. Celestia's native asset, $TIA, serves multiple pivotal roles within the network. It's used to pay for data space, bootstrap new rollups without the immediate need to issue a new token, secure the network through a proof-of-stake mechanism built on the Cosmos SDK, and foster decentralized governance where stakers can influence network parameters and oversee block rewards. With its unique structure and vision, Celestia promises a future where blockchain deployment is as straightforward as creating a smart contract.
