What is Celestia? ✨
Celestia is the first modular blockchain network. By decoupling consensus from execution, Celestia enables anyone to easily deploy their own blockchain, without the overhead of bootstrapping a new consensus network. Blockchains on Celestia are free from constraints. They are simultaneously scalable, sovereign and secure. Developers want Celestia over monolithic architectures for more flexibility and the freedom to build on their own terms.
