The first modular blockchain network

Celestia is a modular consensus and data network, built to enable anyone to easily deploy their own blockchain with minimal overhead.

Advantages

Deploy a blockchain as easily as a smart contract

Celestia provides consensus and security on-demand, enabling anyone to deploy a blockchain without the overhead of bootstrapping a new consensus network.

Scaling made simple with data availability sampling

Because Celestia does not validate transactions, its throughput is not bottlenecked by state execution like traditional blockchains. Thanks to a property of data availability sampling, Celestia’s throughput scales with the number of users.

Secure interoperability for all Celestia chains

Blockchains built on top of Celestia do not rely on honest majority assumptions for state validity, meaning that they can interoperate with the highest security standards.

Choose your own execution environment

Since Celestia does not impose any execution logic, developers are free to define their own execution environments. Celestia will support all flavors of rollups, but we are initially focused on the EVM and Cosmos SDK.

How it works

Celestia is a minimal blockchain that only orders and publishes transactions and does not execute them. By decoupling the consensus and application execution layers, Celestia modularizes the blockchain technology stack and unlocks new possibilities for decentralized application builders.

Traditional monolithic architecture

Developers can only use programming languages supported by chain's execution environment
All applications run on the same process (the world computer model), with shared gas resources
Smart contracts cannot be updated without a hard fork

Celestia-enabled modular architecture

Developers can effortlessly define their own virtual execution environments; similar to virtual machines
Each application gets its own sovereign execution space, while inheriting the security of Celestia's consensus
Applications can be updated without main chain hard forks
