Celestia is the first modular blockchain network that makes it effortless to deploy a new blockchain. It allows sovereign blockchains to break free from the constraints of monolithic architectures so that they can build with flexibility and freedom on their own terms. Celestia has no smart contract features; it only orders data and checks to see if it is available. This is because smart contracts are only necessary for blockchains where applications will live. This decoupling of features alleviates some of the largest problems that hold back blockchains from scaling.
