Advantages

Build

Deploy your own blockchain in minutes, as easily as a smart contract

Scale

Access the dynamic scaling unlocked by data availability sampling, where scale increases with the number of users

Customize

Create applications using your favorite VM or define your own

Sovereign

Build sovereign rollups, a new type of self-governing blockchain with minimal platform risk

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
