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
